Lunheng (Discourses Weighed in the Balance) Discourse on the Sun Wang Chong, a man of the Later Han, gave the sense of his book in four characters — hating what is empty and false. He takes up one by one the sayings of his age: that Heaven answers the affairs of men and sends down calamity, that the dead become ghosts and take revenge, that a man must choose his days or come to harm. The grain of his argument is unlike others'. He does not let a saying stand because an elder said it — he questions Confucius, he pricks Mencius, he holds Han Fei wrong. To the saying that Heaven rebukes men and sends calamity he asks back: then why, for one ruler, does Heaven send drought upon a whole country? Nine chapters bearing the word "empty" stand in a row, taking up in turn the marvels written in the old books, and three bearing the word "swollen" deal with how words grow past their size. The chapter on fortune and misfortune has the tale of Dongmyeong of Buyeo, who shot so well with the bow that the king wished to kill him, and who fled south and came to the Yanhu River. It is the earliest form of the Dongmyeong record that survives.

儒者曰:「日朝見,出陰中;暮不見,入陰中。陰氣晦冥,故沒不見。」如實論之,不出入陰中。何以效之?夫夜,陰也,氣亦晦冥,或夜舉火者,光不滅焉。夜之陰,北方之陰也,朝出(日)〔暮〕入,所舉之火也。火夜舉,光不滅,日暮入,獨不見,非氣驗也。夫觀冬日之出入,朝出東南,暮入西南,東南西南非陰,何故謂之出入陰中?且夫星小猶見,日大反滅,世儒之論,竟虛妄也。

The scholars say, "The sun is seen in the morning because it comes out of the yin; in the evening it is not seen because it goes into the yin. The breath of yin is dark and murky, and so the sun sinks and is not seen." Discussed as it really is, the sun does not come out of the yin or go into it. How is this shown? Night is yin, and its breath too is dark and murky; yet if a man lifts a torch at night, the light is not put out. The yin of night is the yin of the north. What comes out in the morning and goes in at evening is like the torch a man lifts. A torch lifted at night is not put out, but the sun, going in at evening, alone is not seen. This is no proof that the breath does it. Look at where the winter sun comes out and goes in. In the morning it comes out in the southeast, in the evening it goes in in the southwest. The southeast and the southwest are not yin. Why then say that it comes out of the yin and goes into the yin? A star is small and is still seen; the sun is great and is put out instead. The argument of the scholars of the age is empty and false in the end.

儒者曰:「冬日短,夏日長,亦復以陰陽。夏時陽氣多,陰氣少,陽氣光明,與日同耀,故日出輒無鄣蔽。冬陰氣晦冥,掩日之光,日雖出,猶隱不見,故冬日日短,陰多陽少,與夏相反。」如實論之,日之長短,不以陰陽。

The scholars say, "The winter day is short and the summer day is long, and this too is from yin and yang. In summer the breath of yang is much and the breath of yin is little. The breath of yang is bright and shines together with the sun, and so when the sun comes out nothing screens it. In winter the breath of yin is dark and covers the light of the sun, so that although the sun comes out it is still hidden and not seen. Therefore in winter the day is short: yin is much and yang is little, the opposite of summer." Discussed as it really is, the length of the day is not from yin and yang.

何以驗之?復以北方之星。北方之陰,日之陰也,北方之陰,不蔽星光,冬日之陰,何故(猶)〔獨〕滅日明?由此言之,以陰陽說者,失其實矣。實者,夏時日在東井,冬時日在牽牛,牽牛去極遠,故日道短,東井近極,故日道長。夏北至東井,冬南至牽牛,故冬夏節極,皆謂之至,春秋未至,故謂之分。

How is this proved? Again by the stars of the north. The yin of the north is the yin of the sun. The yin of the north does not cover the light of the stars. Why then should the yin of the winter day alone put out the brightness of the sun? From this it is plain that those who explain it by yin and yang have missed the truth. The truth is that in summer the sun is in Dongjing and in winter the sun is in Qianniu. Qianniu is far from the pole, and so the sun's road is short. Dongjing is near the pole, and so the sun's road is long. In summer the sun goes north and reaches Dongjing; in winter it goes south and reaches Qianniu. So the turning points of the winter and summer seasons are both called the arrival, zhi (至), and spring and autumn have not arrived, and so they are called the division, fen (分).

或曰:「夏時陽氣盛,陽氣在南方,故天舉而高;冬時陽氣衰,天抑而下。高則日道多,故日長;下則日道少,故日短也。」(日)〔曰〕:陽氣盛,天南方舉而日道長,月亦當復長。案夏日長之時,日出東北,而月出東南;冬日短之時,日出東南,月出東北。如夏時天舉南方,日月當俱出東北,冬時天復下,日月亦當俱出東南。由此言之,夏時天不舉南方,冬時天不抑下也。然則夏日之長也,其所出之星在北方也;冬日之短也,其所出之星在南方也。問曰:「當夏五月日長之時在東井,東井近極,故日道長,今案察五月之時,日出於寅,入於戌。日道長,去人遠,何以得見其出於寅入於戌乎?」日東井之時,去人極近。夫東井近極,若極旋轉,人常見之矣。使東井在極旁側,得無夜常為晝乎?日晝行十六分,人常見之,不復出入焉。儒者或曰:「日月有九道,故曰日行有近遠,晝夜有長短也。」夫復五月之時,晝十一分,夜五分;六月,晝十分,夜六分;從六月往至十一月,月減一分:此則日行月從一分道也,歲日行天十六道也,豈徒九道?

Someone says, "In summer the breath of yang is at its height, and the breath of yang is in the south, and so heaven is lifted up and high. In winter the breath of yang is weak, and heaven is pressed down and low. When heaven is high the sun's road is long, and so the day is long; when heaven is low the sun's road is short, and so the day is short." I answer: if the breath of yang is at its height, and heaven is lifted in the south, and the sun's road is long, then the moon's road should be long as well. Look: when the summer day is long, the sun comes out in the northeast and the moon comes out in the southeast; when the winter day is short, the sun comes out in the southeast and the moon comes out in the northeast. If in summer heaven were lifted in the south, the sun and the moon should both come out in the northeast; if in winter heaven came down again, the sun and the moon should both come out in the southeast. From this it is plain that in summer heaven is not lifted in the south, and in winter heaven is not pressed down. Then the summer day is long because the star from which the sun comes out is in the north, and the winter day is short because the star from which it comes out is in the south. Question: "In the fifth month of summer, when the day is long, the sun is in Dongjing, and Dongjing is near the pole, and so the sun's road is long. But look at the fifth month: the sun comes out at yin and goes in at xu. If its road is long and it is far from men, how can men see it come out at yin and go in at xu?" When the sun is in Dongjing it is very near to men. If Dongjing were near the pole, it would turn as the pole turns, and men would see it always. If Dongjing stood at the side of the pole, would not night be day forever? If the sun traveled sixteen parts by daylight, men would see it always, and it would no longer come out and go in. Some of the scholars say, "The sun and the moon have nine roads, and so the sun's going is now near and now far, and night and day are now long and now short." But in the fifth month the day is eleven parts and the night five parts; in the sixth month the day is ten parts and the night six parts; and from the sixth month to the eleventh month each month takes away one part. Then the sun's going follows a road of one part each month, and in a year the sun travels sixteen roads in heaven. How should there be only nine?

或曰:「天高南方下北方,日出高故見,入下故不見,天之居若倚蓋矣,故極在人之北,是其效也。極其天下之中,今在人北,其若倚蓋,明矣。」日明既以倚蓋喻,當若蓋之形也;極星在上之北,若蓋之葆矣;其下之南,有若蓋之莖者,正何所乎?夫取蓋倚於地不能運,立而樹之然後能轉。今天運轉,其北際不著地者,觸礙何以能行?由此言之,天不若倚蓋之狀,日之出入不隨天高下,明矣。

Someone says, "Heaven is high in the south and low in the north. The sun comes out high, and so it is seen; it goes in low, and so it is not seen. Heaven rests like a tilted canopy, and so the pole is to the north of men, and that is the proof. The pole is the middle of heaven, and now it lies to the north of men, and so it is clear that heaven is like a tilted canopy." If the brightness of the sun is likened to a tilted canopy, then heaven should have the shape of a canopy. The pole star is above and to the north, like the knob of the canopy. Then below it, in the south, where is the thing that answers to the shaft of the canopy? Take a canopy and tilt it against the ground, and it cannot be turned; stand it up and plant it, and then it can turn. Now heaven turns and moves, and its northern edge does not touch the ground. If it struck and caught, how could it move? From this it is plain that heaven is not shaped like a tilted canopy, and that the coming out and going in of the sun does not follow the height and lowness of heaven.

或曰:「天北際下地中,日隨天而入地,地密鄣隱,故人不見。」然天地,夫婦也,合為一體。天在地中,地與天合,天地并氣,故能生物。北方陰也,合體并氣,故居北方。天運行於地中乎,不則北方之地低下而不平也。如審運行地中,鑿地一丈,轉見水源,天行地中,出入水中乎,如北方低下不平,是則九川北注,不得盈滿也。實者,天不在地中,日亦不隨天隱,天平正與地無異。然而日出上日入下者,隨天轉運,視天若覆盆之狀,故視日上下然,似若出入地中矣。然則日之出,近也,其入遠,不復見,故謂之入,運見於東方近,故謂之出。何以驗之?繫明月之珠於車蓋之,轉而旋之,明月之珠旋邪?

Someone says, "The northern edge of heaven goes down into the earth, and the sun goes into the earth along with heaven; the earth screens it thickly, and so men do not see it." But heaven and earth are husband and wife, and joined they make one body. Heaven is within the earth and the earth joins with heaven; heaven and earth put their breaths together, and so they can bring things to birth. The north is yin; there they join their bodies and put their breaths together, and so it dwells in the north. Does heaven then turn and travel inside the earth, or is the land of the north low and not level? If heaven truly traveled inside the earth, then dig the ground one zhang and the springs of water appear; if heaven traveled inside the earth, would it come out of the water and go into the water? And if the north were low and not level, then the nine rivers would pour northward and could never be filled. The truth is that heaven is not inside the earth, and the sun does not hide along with heaven, and heaven is flat and level, no different from the earth. Yet the sun comes out above and goes in below because it follows the turning of heaven. Heaven is seen as though it were an overturned basin, and so the sun is seen to go up and down in this way, as though it came out of the earth and went into it. So the sun's coming out is its being near, and its going in is its being far and no longer seen, and that is called going in; and when it turns and is seen near in the east, that is called coming out. How is this proved? Hang a bright moon pearl on a carriage canopy and turn it round. Does the bright moon pearl come out and go in?

人望不過十里,天地合矣,遠非合也。今視日入,非入也,亦遠也。當日入西方之時,其下民亦將謂之日中,從日入之下東望今之天下,或時亦天地合,如是方〔今〕天下在南方也,故日出於東方入於北方之地,日出北方,入於南方,各於近者為出,遠者為入,實者不入遠矣。臨大澤之濱,望四邊之際與天屬,其實不屬,遠若屬矣。日以遠為入,澤以遠為屬,其實一也。澤際有陸,人望而不見,陸在,察之若(望)〔亡〕,日亦在,視之若入。皆遠之故也。太山之高,參天入雲,去之百里,不見塊。夫去百里,不見太山,況日去人以萬里數乎?太山之險,則既明矣,試使一人把大炬火夜行於道,平易無險,去人不一里,火光滅矣,非滅也,遠也。

A man's sight does not reach beyond ten li, and there heaven and earth seem to meet; they are far off, and are not joined. Now when the sun is seen to go in, it is not going in; it is only far away. When the sun goes in in the west, the people below it will also call it noon; and looking east from under the place where the sun goes in, toward the world of men here, they too may find that heaven and earth seem to meet. In this way, the world of men here lies to the south, and so it is said that the sun comes out in the east and goes into the land of the north; and where the sun comes out in the north and goes in in the south, each takes what is near for the coming out and what is far for the going in. In truth the sun does not go in; it is far. Stand at the shore of a great marsh and look at the edge on every side, and it seems to join with heaven; in truth it does not join, but it is far and seems to join. The sun takes distance for its going in, and the marsh takes distance for its joining, and the truth of them is one. Beyond the edge of the marsh there is dry land, and a man looks and does not see it; the land is there, but to the eye it is as though gone. The sun too is there, but to the eye it is as though it had gone in. Distance is the cause of both. Mount Tai is so high that it pierces heaven and enters the clouds, yet go a hundred li away and you do not see a lump of it. If at a hundred li Mount Tai is not seen, how much more the sun, whose distance from men is counted in tens of thousands of li! The steepness of Mount Tai is plain already. Try this: let a man take a great torch and walk a road at night, on level ground with nothing steep, and before he is one li from you the torchlight is put out. It is not put out; it is far.

今日西轉不復見者,非入也。問曰:「天平正與地無異,今仰視天,觀日月之行,天高南方下北方,何也?」曰:方今天下在東南之上,視天若高,日月道在人之南,今天下在日月道下,故觀日月之行,若高南下北也。何以驗之?即天高,南方之星亦當高,今視南方之星低下,天復低南方乎?夫視天之居近者則高,遠則下焉,極北方之民以為高,南方為下,極東極西,亦如此焉。皆以近者為高,遠者為下。從北塞下近仰視斗極,且在人上。匈奴之北,地之邊陲,北上視天,天復高北下南,日月之道,亦在其上。立太山之上,太山高,去下十里,太山下。夫天之高下,猶人之察太山也。平正,四方中央高下皆同,今望天之四邊若下者,非也,遠也。非徒下,若合矣。

Now when the sun turns west and is no longer seen, it has not gone in. Question: "If heaven is flat and level, no different from the earth, then why, when we look up at heaven and watch the going of the sun and moon, is heaven high in the south and low in the north?" I answer: the world of men here lies above the southeast, and so heaven seems high to the eye, and the road of the sun and moon lies to the south of men. The world of men here lies below the road of the sun and moon, and so, watching the going of the sun and moon, it seems high in the south and low in the north. How is this proved? If heaven were high, the stars of the south should be high as well; but look at the stars of the south and they are low. Is heaven then low in the south too? When a man looks at where heaven rests, the near part is high and the far part is low. The people at the far north hold the north to be high and the south to be low, and it is the same at the far east and the far west. All take what is near for high and what is far for low. From below the northern frontier, look up nearby at the Dipper and the pole, and they are straight above men. North of the Xiongnu is the rim of the earth; go up north and look at heaven, and again heaven is high in the north and low in the south, and the road of the sun and moon is above it as well. Stand on Mount Tai and Mount Tai is high; go ten li down from it and Mount Tai is low. The height and lowness of heaven is like a man looking at Mount Tai. Heaven is flat and level, and the four quarters and the center are all alike in height and lowness. Now the four edges of heaven seem low to the eye; they are not low, they are far. And not only low: they seem to meet the earth.

儒者或以旦暮日出入為近,日中為遠。或以日中為近,日出入為遠。

Some of the scholars hold that the sun is near at morning and evening, when it comes out and goes in, and far at noon. Others hold that it is near at noon and far when it comes out and goes in.

其以日出入為近,日中為遠者,見日出入時大,日中時小也。察物近則大,遠則小,故日出入為近,日中為遠也。其以日出入為遠,日中時為近者,見日中時溫,日出入時寒也。夫火光近人則溫,遠人則寒,故以日中為近,日出入為遠也。二論各有所見,故是非曲直未有所定。如實論之,日中近而日出入遠,何以驗之?以植竿於屋下,夫屋高三丈,竿於屋棟之下,正而樹之,上扣棟,下抵地,是以屋棟去地三丈。如旁邪倚之,則竿末旁跌,不得扣棟,是為去地過三丈也。日中時,日正在天上,猶竿之正樹,去地三丈也。日出入,邪在人旁,猶竿之旁跌,去地過三丈也。夫如是,日中為近,出入為遠,可知明矣。試復以屋中堂而坐一人,一人行於屋上,其行中屋之時,正在坐人之上,是為屋上之人,與屋下坐人,相去三丈矣。如屋上人在東危若西危上,其與屋下坐人,相去過三丈矣。日中時猶人正在屋上矣,其始出與入,猶人在東危與西危也。日中去人近故溫,日出入遠故寒。然則日中時日小,其出入時大者,日中光明故小,其出入時光暗故大,猶晝日察火光小,夜察之火光大也。既以火為效,又以星為驗,晝日星不見者,光耀滅之也,夜無光耀,星乃見。夫日月,星之類也。平旦日入光銷,故視大也。

Those who hold that the sun is near when it comes out and goes in, and far at noon, have seen that it is big when it comes out and goes in and small at noon. When a man looks at a thing it is big if it is near and small if it is far, and so they say it is near when it comes out and goes in and far at noon. Those who hold that it is far when it comes out and goes in and near at noon have seen that it is warm at noon and cold when the sun comes out and goes in. The light of a fire is warm when it is near a man and cold when it is far from him, and so they say it is near at noon and far when it comes out and goes in. Each of the two arguments has seen something, and so right and wrong, crooked and straight, have not been settled. Discussed as it really is, the sun is near at noon and far when it comes out and goes in. How is this proved? By planting a pole under a roof. The house is three zhang high. Plant the pole upright under the ridgebeam, so that above it strikes the ridgebeam and below it reaches the ground, and the ridgebeam is three zhang from the ground. Tilt the pole to the side, and its end slips away and cannot reach the ridgebeam, and the distance from the ground is more than three zhang. At noon the sun stands straight above in heaven, like the pole planted upright, three zhang from the ground. When the sun comes out and goes in, it is aslant at a man's side, like the pole slipped to the side, more than three zhang from the ground. This being so, it may be known plainly that the sun is near at noon and far when it comes out and goes in. Try it again: let one man sit in the hall of a house and another walk on the roof. When his walking is at the middle of the roof he is straight above the man sitting, and the man on the roof and the man sitting below are three zhang apart. When the man on the roof is on the east eaves or the west eaves, he and the man sitting below are more than three zhang apart. Noon is like the man straight above on the roof, and the first coming out and the going in are like the man at the east eaves and the west eaves. At noon the sun is near to men, and so it is warm; when it comes out and goes in it is far, and so it is cold. Then why is the sun small at noon and big when it comes out and goes in? At noon its light is bright, and so it is small; when it comes out and goes in its light is dim, and so it is big. It is like a fire, whose light is small when a man looks at it by day and big when he looks at it by night. Fire has been taken for proof; take the stars for proof as well. The stars are not seen by day because the glare puts them out; at night there is no glare, and then the stars are seen. The sun and moon are of the same kind as the stars. At dawn and at the sun's going in the light melts away, and so to the eye it is big.

儒者論日旦出扶桑,暮入細柳。扶桑,東方地;細柳,西方野也。

The scholars argue that the sun comes out of Fusang in the morning and goes into Xiliu in the evening. Fusang is a land of the east, and Xiliu is a field of the west.

桑、柳,天地之際,日月常所出入之處。問曰:歲二月八月時,日出正東,日入正西,可謂日出於扶桑,入於細柳。今夏日長之時,日出於東北,入於西北,冬日短之時,日出東南,入於西南,冬與夏日之出入,在於四隅,扶桑、細柳,正在何所乎?所論之言,猶謂春秋,不謂冬與夏也。如實論之,日不出於扶桑,入於細柳。何以驗之?隨天而轉,近則見,遠則不見。當在扶桑、細柳之時,從扶桑、細柳之民,謂之日中之時,從扶桑、細柳察之,或時為日出入,(若)〔皆〕以其上者為中,旁則為旦夕,安得出於扶桑入細柳?儒者論曰:天左旋,日月之行,不繫於天,各自旋轉。

Fusang and Xiliu, they say, are the ends of heaven and earth, the places where the sun and moon always come out and go in. Question: in the second month and the eighth month of the year the sun comes out due east and goes in due west, and one may say that it comes out of Fusang and goes into Xiliu. But when the summer day is long the sun comes out in the northeast and goes in in the northwest, and when the winter day is short it comes out in the southeast and goes in in the southwest. In winter and summer the sun comes out and goes in at the four corners. Where then do Fusang and Xiliu stand? What they argue holds for spring and autumn, and not for winter and summer. Discussed as it really is, the sun does not come out of Fusang or go into Xiliu. How is this proved? It turns along with heaven; when it is near it is seen, and when it is far it is not seen. When it is over Fusang and Xiliu, the people of Fusang and Xiliu will call it noon; and looked at from Fusang and Xiliu, it may at that time be coming out and going in elsewhere. All take what is above them for the middle of the day and what is at their side for morning and evening. How then should it come out of Fusang and go into Xiliu? The scholars argue and say: heaven turns to the left, and the going of the sun and moon is not tied to heaven, but each turns of itself.

難之曰:使日月自行,不繫於天,日行一度,月行十三度,當日月出時,當進而東旋,何還始西轉?繫於天,隨天四時轉行也。其喻若蟻行於上,日月行遲天行疾,天持日月轉,故日月實東行,而反西旋也。

I object and say: if the sun and moon went of themselves and were not tied to heaven, the sun going one degree and the moon thirteen degrees, then when the sun and moon come out they should go forward and turn east. Why do they turn west as at the first? They are tied to heaven, and they turn and go along with heaven through the four seasons. The likeness is an ant walking on a millstone. The going of the sun and moon is slow and the going of heaven is swift; heaven holds the sun and moon and turns, and so the sun and moon in truth go east while they turn west instead.

或問:「日、月、天皆行,行度不同,三者舒疾,驗之人物,(為)〔何〕以(何)〔為〕喻?」

Someone asks, "The sun, the moon and heaven all go, and the degrees of their going are not the same. If we prove the slowness and swiftness of the three by men and things, to what shall we liken them?"

曰:天,日行一周。日行一度二千里,日晝行千里,行千里,(麒麟)〔騏驥〕晝日亦行千里。然則日行舒疾,與(麒麟)〔騏驥〕之步相似類也。月行十三度,十度二萬里,三度六千里,月一(旦)〔日〕〔一〕夜行二萬六千里,與晨鳧飛相類似也。

I answer: heaven goes one round in a day. The sun goes one degree, two thousand li. By daylight the sun goes a thousand li, and a qiji horse also goes a thousand li in a day. So the slowness and swiftness of the sun's going is of the same sort as the step of a qiji. The moon goes thirteen degrees: ten degrees are twenty thousand li and three degrees six thousand li, and so the moon goes twenty-six thousand li in one day and one night. This is of the same sort as the flight of a wild duck at dawn.

天行三百六十五度,積凡七十三萬里也,其行甚疾,無以為驗,當與陶鈞之運,弩矢之流,相類似乎!天行已疾,去人高遠,視之若遲,蓋望遠物者,動若不動,行若不行。何以驗之?乘船江海之中,順風而驅,近岸則行疾,遠岸則行遲,船行一實也,或疾或遲,遠近之視,使之然也。仰視天之運,不若(麒麟)〔騏驥〕負日而馳,(皆)〔比〕〔日〕暮而日在其前,

Heaven goes three hundred and sixty-five degrees, seven hundred and thirty thousand li in all. Its going is very swift, and there is nothing by which to prove it; it must be of the same sort as the turn of a potter's wheel and the flight of a crossbow bolt. The going of heaven is swift already, but it is high and far from men, and to the eye it seems slow. When a man looks at a far-off thing, it seems not to move though it moves, and not to go though it goes. How is this proved? Ride a boat on a river or the sea and run before the wind: near the bank the going is swift, and far from the bank the going is slow. The going of the boat is one and the same, yet it is now swift and now slow; seeing it from near and from far makes it so. Look up at the turning of heaven, and it is not like a qiji running with the sun on its back. Set them against each other at evening, and the sun is ahead of it.

何則?(麒麟)〔騏驥〕近而日遠也。遠則若遲,近則若疾,六萬里之程,難以得運行之實也。

Why? The qiji is near and the sun is far. What is far seems slow and what is near seems swift, and in a course of sixty thousand li it is hard to get at the truth of the turning and going.

儒者說曰:「日行一度,天一日一夜行三百六十五度,天左行,日月右行,與天相迎。」問:日月之行也,繫著於天也,日月附天而行,不(直)〔自〕行也。何以言之?《易》曰:「日月星辰麗乎天,百果草木麗於土。」麗者,附也。附天所行,若人附地而圓行,其取喻若蟻行於上焉。問曰:「何知不離天直自行也?」如日能直自行,當自東行,無為隨天而西轉也。月行與日同,亦皆附天。何以驗之?驗之(似)〔以〕雲。雲不附天,常止於所處,使不附天,亦當自止其處。由此言之,日行附天明矣。

The scholars explain it and say, "The sun goes one degree, and heaven goes three hundred and sixty-five degrees in one day and one night. Heaven goes to the left and the sun and moon go to the right, and they meet heaven face to face." Question: the going of the sun and moon is tied and fastened to heaven; the sun and moon cling to heaven and go, and they do not go of themselves. How do I say so? The Yi says, "The sun, the moon and the stars cling to heaven; the hundred fruits and the grasses and trees cling to the earth." To cling, li (麗), is to be attached. What is attached to heaven and goes is like a man attached to the earth and going round it, and the likeness taken for it is an ant walking on a millstone. Question: "How do you know that they do not leave heaven and go straight of themselves?" If the sun could go straight of itself, it should go east of itself, and there would be no reason for it to follow heaven and turn west. The going of the moon is the same as the going of the sun, and both of them cling to heaven. How is this proved? It is proved by the clouds. The clouds do not cling to heaven, and they stay always in the place where they are; if the sun did not cling to heaven, it too should stay of itself in its place. From this it is plain that the going of the sun clings to heaven.

問曰:「日,火也。火在地不行,日在天,何以為行?」曰:附天之氣行,附地之氣不行。火附地,地不行,故火不行。難曰:「附地之氣不行,水何以行?」曰:水之行也,東流入海也。

Question: "The sun is fire. Fire on the earth does not go; the sun is in heaven, and how is it that it goes?" I answer: the breath that clings to heaven goes, and the breath that clings to the earth does not go. Fire clings to the earth, and the earth does not go, and so fire does not go. It is objected: "If the breath that clings to the earth does not go, how is it that water goes?" I answer: the going of water is its flowing east into the sea.

西北方高,東南方下,水性歸下,猶火性趨高也。使地不高西方,則水亦不東流。難曰:「附地之氣不行,人附地何以行?」曰:人之行,求有為也。人道有為,故行求。古者質朴,鄰國接境,雞犬之聲相聞,終身不相往來焉。難曰:「附天之氣行,列星亦何以不行?」曰:列星著天,天已行也,隨天而轉,是亦行也。難曰:「人道有為故行,天道無為何行?」曰:天之行也,施氣自然也,施氣則物自生,非故施氣以生物也。不動,氣不施,氣不施,物不生,與人行異。日月五星之行,皆施氣焉。

The northwest is high and the southeast is low. The nature of water is to return downward, as the nature of fire is to run upward. If the land were not high in the west, water too would not flow east. It is objected: "If the breath that clings to the earth does not go, how is it that men cling to the earth and go?" I answer: the going of a man is a seeking to do. The way of man is to do, and so he goes and seeks. In old times men were plain and simple; neighboring states touched at their borders and the sound of their cocks and dogs was heard from one to the other, yet to the end of their lives they did not go to and fro. It is objected: "If the breath that clings to heaven goes, how is it that the host of stars does not go?" I answer: the host of stars is fixed to heaven, and heaven goes already; to turn along with heaven is also to go. It is objected: "The way of man is to do, and so he goes; the way of heaven does nothing, and how then does it go?" I answer: the going of heaven is the giving out of breath, and it is so of itself. Give out breath, and things are born of themselves; heaven does not give out breath on purpose in order to bear things. If it did not move, breath would not be given out; if breath were not given out, things would not be born. This is unlike the going of man. The going of the sun, the moon and the five stars all gives out breath.

儒者曰:「日中有三足烏,月中有兔、蟾蜍。」夫日者,天之火也,與地之火,無以異也。地火之中無生物,天火之中何故有烏?火中無生物,生物入火中,爛而死焉,烏安得立?夫月者,水也,水中有生物,非兔、蟾蜍也。兔與蟾蜍久在水中,無不死者。日月毀於天,螺蚌汨於淵,同氣審矣,所謂兔、蟾蜍者,豈反螺與蚌邪?且問儒者:烏、兔、蟾蜍,死乎生也?如死,久在日月,枯腐朽。如生,日蝕時既,月晦常盡,烏、兔、蟾蜍皆何在?夫烏、兔、蟾蜍,日月氣也,若人之腹髒,萬物之心膂也。月尚可察也,人之察日無不眩,不能知日審何氣,通而見其中有物名曰烏乎?審日不能見烏之形,通而能見其足有三乎?此已非實。且聽儒者之言,蟲物非一,日中何為有烏,月中何為有兔、蟾蜍?

The scholars say, "In the sun there is a three-footed crow; in the moon there are a hare and a toad." Now the sun is the fire of heaven, and it is no different from the fire of the earth. In the fire of the earth there is no living thing; why should there be a crow in the fire of heaven? There is no living thing in fire, and a living thing that goes into fire is scorched and dies. How should a crow stand there? The moon is water. There are living things in water, but they are not hares and toads. A hare or a toad long in the water would die without fail. When the sun and moon wane in heaven, conches and clams dwindle in the deeps, and it is clear that their breath is the same. Then are what they call the hare and the toad the conch and the clam instead? And I ask the scholars: are the crow, the hare and the toad dead or alive? If they are dead, they have been long in the sun and the moon, and they are dried and rotted. If they are alive, then when the sun is wholly eaten, and when the moon is always spent at the month's end, where are the crow, the hare and the toad? The crow, the hare and the toad are the breath of the sun and moon, like the organs in a man's belly, like the heart and the backbone of the ten thousand things. The moon may still be looked at, but no man looks at the sun without being dazzled. He cannot know what breath the sun truly is; shall he see through it and see a thing inside it and name it a crow? If he truly cannot see the shape of a crow in the sun, shall he see through it and see that its feet are three? This is not the truth already. And hear the words of the scholars: creatures and things are not of one kind. Why then should there be a crow in the sun and a hare and a toad in the moon?

儒者謂日蝕、月蝕也。彼見日蝕常於晦朔,晦朔月與日合,故得蝕之。

The scholars say that when the sun is eaten, it is the moon that eats it. They have seen that the sun is eaten always at the month's end or on the first day, and that at the month's end and on the first day the moon joins with the sun, and so they say it can eat it.

夫春秋之時,日蝕多矣。《經》曰:某月朔,日有蝕之。日有蝕之者,未必月也。知月蝕之,何諱不言月?說日蝕之變,陽弱陰強也,人物在世,氣力勁強,乃能乘凌。案月晦光既,朔則如盡,微弱甚矣,安得勝日?夫日之蝕,月蝕也。日蝕謂月蝕之,月誰蝕之者,無蝕月也,月自損也。以月論日,亦如日蝕,光自損也。

In the time of the Chunqiu the sun was eaten many times. The Classic says: in such a month, on the first day, there was an eating of the sun. "There was an eating of the sun" need not mean the moon. If it were known that the moon ate it, why should the writer shun the word and not say the moon? Speaking of the strangeness of the sun's eating, they say that yang is weak and yin is strong. Among men and things in the world, only what is stout and strong in force can ride over another and put it down. Look: at the month's end the moon's light is done, and on the first day it is as though spent; its weakness is extreme. How should it overcome the sun? The eating of the sun is like the eating of the moon. If the eating of the sun is the moon eating it, who eats the moon? Nothing eats the moon; the moon takes from itself. Argue from the moon to the sun, and the eating of the sun too is a light taking from itself.

大率四十一二月日一食,百八十日月一蝕,蝕之皆有時,非時為變,及其為變,氣自然也。日時晦朔,月復為之乎?夫日當實滿,以虧為變,必謂有蝕之者,山崩地動,蝕者誰也?或說:「日食者,月掩之也,日在上,月在下,障於(日)〔月〕之形也。日月合相襲,月在上日在下者,不能掩日。日在上,月在日下,障於日,月光掩日光,故謂之食也,障於月也,若陰雲蔽日月不見矣。其端合者,相食是也。其合相當如襲(辟)〔璧〕者,日既是也。」

Roughly, in forty-one or forty-two months the sun is eaten once, and in a hundred and eighty days the moon is eaten once. Their eatings all have their times; what is out of its time is held a strange thing, and even when it becomes a strange thing, the breath is so of itself. The sun is eaten at the month's end and on the first day; does the moon do it again and again? The sun ought to be full and whole, and its waning is taken for a strange thing. If it must be said that something eats it, then when mountains fall and the earth shakes, who is the eater? Someone explains it and says, "The eating of the sun is the moon covering it. The sun is above and the moon is below, and the sun is screened by the shape of the moon. When the sun and moon join and lie one on the other, with the moon above and the sun below, the moon cannot cover the sun. When the sun is above and the moon is below the sun and screens the sun, the light of the moon covers the light of the sun, and so we say it is eaten. It is screened by the moon, as when dark clouds hide the sun and moon so that they are not seen. When their edges join, that is the eating of one by the other; and when they join and match like two jade discs laid one on the other, that is the sun wholly eaten."

日月合於晦朔,天之常也。日食,月掩日光,非也。何以驗之?使日月合,月掩日光,其初食崖當與旦復時易處。假令日在東,月在西,月之行疾,東及日,掩日崖,須臾過日而東,西崖初掩之處光當復,東崖未掩者當復食。今察日之食,西崖光缺,其復也,西崖光復,過掩東崖復西崖,謂之合襲相掩障,如何?

That the sun and moon join at the month's end and on the first day is the constant way of heaven; but that the eating of the sun is the moon covering the light of the sun is wrong. How is this proved? If the sun and moon joined and the moon covered the light of the sun, then the edge first eaten should change places with the edge that comes back at the end. Suppose the sun is in the east and the moon in the west. The moon goes swiftly and comes east up to the sun and covers the sun's edge, and in a moment it passes the sun and goes east. Then the light of the west edge, the place first covered, should come back, and the east edge, not yet covered, should be eaten in its turn. Now look at the eating of the sun: the light of the west edge is gone, and when it comes back, it is the light of the west edge that comes back. To pass over and cover, going to the east edge and then back to the west edge, and to call this joining and lying one on the other and screening, how can it be?

儒者謂日月之體皆至圓,彼從下望見其形,若斗筐之狀,狀如正圓,不如望遠光氣,氣不圓矣。夫日月不圓,視若圓者,〔去〕人遠也。何以驗之?夫日者,火之精也;月者,水之精也。在地水火不圓,在天水火何故獨圓?日月在天猶五星,五星猶列星,列星不圓,光耀若圓,去人遠也。何以明之?春秋之時,星宋都,就而視之,石也,不圓。以星不圓,知日月五星亦不圓也。

The scholars hold that the bodies of the sun and moon are both perfectly round. They look up at their shape from below and find it like the shape of a measure or a basket, a form truly round; but this is not as good as looking at the far-off light and breath, and the breath is not round. The sun and moon are not round, and they seem round because they are far from men. How is this proved? The sun is the essence of fire and the moon is the essence of water. On the earth water and fire are not round; why in heaven should water and fire alone be round? The sun and moon in heaven are like the five stars, and the five stars are like the host of stars. The host of stars is not round, and its light seems round because it is far from men. How is this made plain? In the time of the Chunqiu stars fell on the capital of Song. Men went and looked at them, and they were stones, and not round. Because the stars are not round it is known that the sun, the moon and the five stars are not round either.

儒者說日及工伎之家,皆以日為一。禹、(貢)〔益〕《山海經》言日有十,在海外東方有湯谷,上有扶桑,十日浴沐水中,有大木,九日居下枝,一日居上枝。

The scholars who speak of the sun, and the masters of the crafts, all take the sun to be one. The Shanhai jing of Yu and Yi says that there are ten suns. Beyond the sea, in the east, there is Tanggu, and above it is Fusang; the ten suns bathe in the water, and there is a great tree, and nine suns dwell on its lower branches and one sun dwells on its upper branch.

《淮南書》又言燭十日,堯時十日并出,萬物焦枯,堯上射十日,以故不并一日見也。世俗又名甲乙為日,甲至癸凡十日,日之有十,猶星之有五也。通人談士,歸於難知,不肯辨明。是以文二傳而不定,世兩言而無主。誠實論之,且無十焉。何以驗之?夫日猶月也,日而有十,月有十二乎?星有五,五行之精,金木水火土各異光色。如日有十,其氣必異。今觀日光無有異者,察其小大前後若一。如審氣異,光色宜殊;如誠同氣,宜合為一,無為十也。驗日陽遂,火從天來,日者、大火也,察火在地,一氣也,地無十火,天安得十日?然則所謂十日者,殆更自有他物,光質如日之狀,居湯谷中水,時緣據扶桑,禹、益見之,則紀十日。數家度日之光,數日之質,刺徑千里,假令日出是扶桑木上之日,扶桑木宜覆萬里,乃能受之。何則?一日徑千里,十日宜萬里也。天之去人萬里餘也,仰察之,日光眩耀,火光盛明,不能堪也。使日出是扶桑木上之日,禹、益見之,不能知其為日也。何則?仰察一日,目猶眩耀,況察十日乎?當禹、益見之,若斗筐之狀,故名之為日。夫火如斗筐,望六萬之形,非就見之,即察之體也。由此言之,禹、益所見,意似日非日也。天地之間,物氣相類,其實非者多。海外西南有珠樹焉,察之是珠,然非魚中之珠也。夫十日之日,猶珠樹之珠也,珠樹似珠非真珠,十日似日非實日也。淮南見《山海經》,則虛言真人燭十日,妄紀堯時十日并出。且日,火也;湯谷,水也。水火相賊,則十日浴於湯谷,當滅敗焉。火燃木,扶桑,木也,十日處其上,宜枯焉。今浴湯谷而光不滅,登扶桑而枝不不枯,與今日出同,不驗於五行,故知十日非真日也。且禹、益見十日之時,終不以夜,猶以晝也,則一日出,九日宜留,安得俱出十日?如平旦日未出,且天行有度數,日隨天轉行,安得留扶桑枝間,浴湯谷之水乎?

The Huainan book says further that the Torch Dragon lit the ten suns, and that in the time of Yao ten suns came out together and the ten thousand things were scorched and withered, and that Yao shot upward at the ten suns, and that for this reason they are not seen together as one sun. The common people also name the days by jia and yi, and from jia to gui is ten days in all, and they say that the sun being ten is like the stars being five. Men of wide learning and masters of talk put it away as hard to know and are unwilling to make it clear. So the writings come down in two forms and are not settled, and the world speaks with two voices and has no master. Truly discussed as it is, there are not ten. How is this proved? The sun is like the moon; if there are ten suns, are there twelve moons? The stars are five, the essences of the five elements, and metal, wood, water, fire and earth differ each in light and color. If there were ten suns, their breath would have to differ. Now look at the sunlight, and there is nothing different in it; look at its size and at its order, first and last, and it is all one. If their breath truly differed, their light and color should be unlike; and if their breath is truly the same, they should join into one, and there is no reason for them to be ten. Prove the sun by the burning mirror, and the fire comes down from heaven. The sun is a great fire. Look at fire on the earth, and it is one breath; on the earth there are not ten fires, and how should heaven have ten suns? Then what are called the ten suns are perhaps some other thing, whose light and substance are like the shape of the sun, dwelling in the water of Tanggu and at times climbing and resting on Fusang. Yu and Yi saw them, and so they wrote down ten suns. The reckoners measure the light of the sun and count the substance of the sun, and its diameter is a thousand li. Suppose the sun that comes out were this sun on the Fusang tree: then the Fusang tree would have to cover ten thousand li to hold them. Why? Because one sun is a thousand li across, and ten suns should be ten thousand li. Heaven is more than ten thousand li from men, and looking up at it the sunlight dazzles the eye, and the light of the fire is so strong that no man can bear it. If the sun that comes out were this sun on the Fusang tree, Yu and Yi could not have seen it and known it for the sun. Why? Looking up at one sun the eyes are dazzled already; how much more at ten suns! When Yu and Yi saw them they were like the shape of a measure or a basket, and so they named them suns. A fire like a measure or a basket is a shape seen at sixty thousand li; they did not go up and see it, and it is not the body they looked at. From this it is plain that what Yu and Yi saw seemed to be suns and were not suns. Between heaven and earth things and breaths resemble one another, and many of them are not what they seem. Beyond the sea, in the southwest, there is a pearl tree. Look at it and it is pearls, yet they are not the pearls that come from a fish. The suns of the ten suns are like the pearls of the pearl tree: the pearl tree is like pearls and is not true pearls, and the ten suns are like suns and are not real suns. Huainan saw the Shanhai jing, and so he said emptily that a true man lit the ten suns, and wrote down wildly that in the time of Yao ten suns came out together. Moreover the sun is fire and Tanggu is water, and water and fire harm one another; if ten suns bathed in Tanggu they should be put out and undone. Fire burns wood, and Fusang is a tree; if ten suns dwelt above it, it should wither. Now they bathe in Tanggu and their light is not put out, and they climb Fusang and its branches do not wither, and it is the same as the sun that comes out today. This is not borne out by the five elements, and so it is known that the ten suns are not true suns. And when Yu and Yi saw the ten suns it was surely not at night but by day; then when one sun came out the nine should have stayed. How should ten suns come out together? And if at dawn the sun had not yet come out, still the going of heaven has its degrees and number, and the sun turns and goes along with heaven. How should it stay among the branches of Fusang and bathe in the water of Tanggu?

留則失行度,行度差跌不相應矣。如行出之日與十日異,是意似日而非日也。

If it stayed, it would lose the degrees of its going, and the degrees would fall out of step and no longer answer one another. And if the sun that goes and comes out differs from the ten suns, then these seemed to be suns and were not suns.

《春秋》莊公七年:「夏四月辛卯,夜中恆星不見,星如雨。」(者)《公羊傳》曰「如雨者何?非雨也。非雨則曷為謂之如雨?不修《春秋》曰:雨星,不及地尺而復。君子修之曰:星如雨。」不修《春秋》者,未修《春秋》時魯史記,曰「(星如)雨〔星〕,不及地尺而復」。君子者,孔子,孔子修之曰「星如雨」孔子之意以為地有山陵樓台,云不及地尺,恐失其實,更正之曰如雨。如雨者,為從地上而下,星亦從天而復,與同,故曰如。夫孔子雖云不及地尺,但言如雨,其謂之者,皆是星也。孔子雖定其位,著其文,謂為星,與史同焉。從平地望泰山之巔,鶴如烏,烏如爵者,泰山高遠,物之小大失其實。天之去地六萬餘里,高遠非直泰山之巔也;星著於天,人察之,失星之實,非直望鶴烏之類也。數等,星之質百里,體大光盛,故能垂耀,人望見之,若鳳卵之狀,遠失其實也。如星審者,天之星而至地,人不知其為星也。何則?時小大不與在天同也。今見星如在天時,是時星也非星,則氣為之也。人見鬼如死人之狀,其實氣象聚,非真死人。然則星之形,其實非星。孔子云正者,非星而徙,正言如雨非雨之文,蓋俱失星之實矣。《春秋》《左氏傳》:「四月辛卯,夜中恆星不見,夜明也;星如雨,與雨俱也。」其言夜明,故不見,與《易》之言日中見斗相依類也。日中見斗,幽不明也;夜中星不見,夜光明也。事異義同,蓋其實也。其言與雨俱之,集也。夫辛卯之夜明,故星不見,明則不雨之驗也,雨氣陰暗安得明?明則無雨,安得與雨俱?夫如是言與雨俱者非實,且言夜明不見,安得見星與雨俱?又僖公十六年正月戊申,石於宋五,《左氏傳》曰:「星也。」夫謂石為星,則謂為石矣。辛卯之夜星,為星則實為石矣。辛卯之夜,星如是石,地有樓台,樓台崩坏。孔子雖不合言及地尺,雖地必有實數,魯史目見,不空言者也,雲與雨俱,雨集於地,石亦宜然。至地而樓台不坏,非星明矣。且左丘明謂石為星,何以審之?當時石輕然。

The Chunqiu, in the seventh year of Duke Zhuang, says, "In summer, in the fourth month, on the day xinmao, in the middle of the night the fixed stars were not seen, and the stars were like rain." The Gongyang Commentary says, "What is 'like rain'? It was not rain. If it was not rain, why is it called like rain? The unrevised Chunqiu said: stars rained down, and before they came within a foot of the ground they went back up. The gentleman revised it and said: the stars were like rain." The unrevised Chunqiu is the record of the historians of Lu before the Chunqiu was revised, which said, "Stars rained down, and before they came within a foot of the ground they went back up." The gentleman is Confucius. Confucius revised it and said, "The stars were like rain." The meaning of Confucius was this: on the earth there are hills and mounds and towers and terraces, and to say that they did not come within a foot of the ground would be to miss the truth, and so he set it right and said "like rain." "Like rain" means that rain comes down from above the ground, and the stars too came back from heaven; they were alike, and so he said "like." Though Confucius did not say "within a foot of the ground" but only "like rain," what both of them named were stars. Though Confucius fixed their place and set down his words, in calling them stars he was at one with the historians. Look from level ground at the peak of Mount Tai, and a crane is like a crow and a crow like a sparrow, because Mount Tai is high and far and the size of things loses its truth. Heaven is more than sixty thousand li from the earth, and its height and distance are not merely those of the peak of Mount Tai. The stars are fixed to heaven, and when a man looks at them he loses the truth of the stars, and it is not merely like looking at cranes and crows. By the reckoning, the substance of a star is a hundred li; its body is great and its light is strong, and so it can hang down its shining, and a man looks at it and it is like the shape of a phoenix egg, for distance has lost its truth. If they were truly stars, then when a star of heaven came to the ground a man would not know it for a star. Why? Because its size then would not be the same as in heaven. Now these stars were seen as they are in heaven; then the stars of that time were not stars, and breath made them. A man sees a ghost in the shape of a dead man, and in truth it is the shapes of breath gathered, and not a real dead man. So the shape of those stars was in truth not a star. What Confucius is said to have set right was a thing that was not a star and moved, and his setting right of the words "like rain, and not rain" misses the truth of the stars all the same. The Zuo Commentary on the Chunqiu says, "In the fourth month, on the day xinmao, in the middle of the night the fixed stars were not seen: the night was bright. The stars were like rain: they came together with the rain." Its saying that the night was bright and so they were not seen is of the same sort as the saying in the Yi that at noon the Dipper is seen. At noon the Dipper is seen when it is dark and not bright; in the middle of the night the stars are not seen when the night is light and bright. The matters differ and the sense is the same, and this is likely the truth. Its saying that they came together with the rain means that they gathered. Now if the night of xinmao was bright and so the stars were not seen, then brightness is proof that it did not rain. The breath of rain is dark and murky; how should it be bright? If it was bright there was no rain, and how then should they come together with the rain? This being so, to say that they came together with the rain is not the truth; and having said that the night was bright and they were not seen, how could one see the stars coming together with the rain? Again, in the sixteenth year of Duke Xi, in the first month, on the day wushen, five stones fell in Song, and the Zuo Commentary says, "They were stars." Now if stones are called stars, then stars are called stones. If the stars of the night of xinmao were stars, then in truth they were stones; and if the stars of the night of xinmao were like these stones, then where there were towers and terraces on the ground, the towers and terraces would have been thrown down. Though Confucius did not agree to say "within a foot of the ground," there must have been a true measure on the ground, and the historians of Lu saw it with their eyes and did not speak emptily. Clouds go together with rain, and the rain gathers on the ground, and the stones should do the same. They came to the ground and the towers and terraces were not thrown down, and it is plain that they were not stars. And how did Zuo Qiuming look into it, to call stones stars? Were the stones of that time light?

何以其從天墜也,秦時三山亡,亡(有)〔者〕不消散,有在其集下時必有聲音,或時夷狄之山從集於宋,宋聞石,則謂之星也,左丘明省,則謂之星。夫星,萬物之精,與日月同。說五星者,謂五行之精之光也,五星眾星同光耀,獨謂列星為石,恐失其實。實者辛卯之夜,星若雨而非星也,與彼湯谷之十日,若日而非日也。

How do they know that they fell from heaven? In the time of Qin three mountains vanished, and what vanishes does not melt away; when they came down and gathered there must have been a sound. It may be that a mountain of the barbarians came and gathered in Song, and Song heard of stones and called them stars, and Zuo Qiuming looked into it and called them stars. Now the stars are the essence of the ten thousand things and are one with the sun and moon. Those who speak of the five stars say that they are the light of the essence of the five elements. The five stars and the host of stars shine with the same light, and to call the host of stars stones alone is, I fear, to miss the truth. The truth is that on the night of xinmao the stars were like rain and were not stars, just as the ten suns of Tanggu were like suns and were not suns.

儒者又曰:雨從天下,謂正從天墜也。如(當)〔實〕論之,雨從地上不從天下,見雨從上集,則謂從天下矣,其實地上也。然其出地起於山。何以明之?《春秋傳》曰:「觸石而出,膚寸而合,不崇朝而遍天下,惟太山也。」

The scholars say further that rain comes down from heaven, meaning that it falls straight down from heaven. Discussed as it really is, rain comes up from the earth and does not come down from heaven. Seeing the rain gather above, they say it comes down from heaven; but in truth it is from the earth. Yet its coming out of the earth rises in the mountains. How is this made plain? The commentary on the Chunqiu says, "It strikes the rocks and comes out, it joins inch by inch, and before the morning is over it covers all under heaven: only Mount Tai does this."

太山雨天下,小山雨一國,各以小大為近遠差。雨之出山,或謂雲載而行,雲散水墜,名為雨矣。夫雲則雨,雨則雲矣,初出為雲,雲繁為雨,猶甚而泥露濡污衣服,若雨之狀,非雲與俱,雲載行雨也。或曰:《尚書》曰:「月之從星,則以風雨。」《詩》曰:「月麗於畢,俾滂㩗矣。」二經咸言,所謂為之非天,如何?夫雨從山發,月經星麗畢之時,麗畢之時當雨也。時不雨,月不麗,山不雲,天地上下自相應也。月麗於上,山於下,氣體偶合,自然道也。雲霧,雨之徵也,夏則為露,冬則為霜,溫則為雨,寒則為雪。雨露凍凝者,皆由地發,不從天降也。

Mount Tai rains on all under heaven and a small mountain rains on one state, and each makes the difference of near and far by its size. Of the coming of rain out of the mountains, some say that the clouds carry it as they go, and that when the clouds scatter the water falls, and that this is named rain. But cloud is rain and rain is cloud: what first comes out is cloud, and when the cloud thickens it is rain. It is like a heavy mud-dew that wets and stains the clothes and has the look of rain. It is not that the cloud goes along with the rain, that the cloud carries the rain as it goes. Someone says: the Shangshu says, "When the moon follows the stars, there will be wind and rain," and the Shi says, "When the moon clings to Bi, it brings a downpour." Both classics say it; how then can you say that what does it is not heaven? Rain rises from the mountains, and when the moon passes the stars and clings to Bi, at the time of its clinging to Bi it ought to rain. When it does not rain at that time, the moon does not cling and the mountains send up no clouds: heaven and earth, above and below, answer one another of themselves. The moon clings above and the mountain sends up clouds below, and breath and body meet and join, and this is the way of nature. Cloud and mist are the sign of rain; in summer they become dew and in winter frost, and when it is warm they become rain and when it is cold snow. Rain and dew and what freezes and congeals all rise from the earth and do not come down from heaven.
