Presocratic Philosophers

"Any explanation... of night will... be an explanation of day, and vice versa; for it will be an account of that which is common... manifests itself now as one and now as the other. ...[B]ecause it has manifested... in the one form... it must next appear in the other... [as] required by the law of compensation or Justice."

"Herakleitos meant to say, not that day was night or that night was day, but that they were two sides of the same process, namely, the oscillation of the "measures" of fire and water, and... neither would be possible without the other."

"[A] number of Herakleitean fragments... form a class by themselves, and are among the most striking... Their common characteristic... they assert... the identity of... things... usually regarded as opposites."

"The painter produces his harmonious effects by the contrast of colours, the musician by that of high and low notes. "If one were to make all things alike, there would be no delight in them." There are many similar examples in the Hippokratean tract, some... come from Herakleitos; but it is not easy to separate them..."

"The argument was that men... act just in the same way as Nature, and it is therefore surprising that they do not recognise the laws by which she works."

"We know from Philo that Herakleitos supported his theory of the attainment of harmony through strife... There is... agreement between a passage of this kind in the pseudo-Aristotelian treatise... The Kosmos, and the Hippokratean work... [B]oth drew from... Herakleitos... made practically certain by the fact that this agreement extends... to the Letters of Herakleitos, which, though spurious, were... composed by some one who had access to the original work."

"[N]either fire nor water can prevail completely... The whole process depends... on the fact that Surfeit is... Want... [i.e.,] an advance of fire increases the moist exhalation, while an advance of water deprives the fire of the power to cause evaporation. The conflagration... would destroy the opposite tension on which the rise of a new world depends, and... motion would become impossible."

"[M]an, like the heavenly bodies, oscillates between fire and water; and that is... what Herakleitos taught."

"[I]n fr. 20 it is this world, and not merely the "ever-living fire," which is... eternal; and... its eternity depends upon... always kindling and always going out in the same "measures"... [i.e.,] encroachment in one direction is compensated by... encroachment in the other."

"[In] fr. 43... Herakleitos blames Homer for desiring the cessation of strife... The cessation of strife would mean that all things should take the upward or downward path... and cease to “run in opposite directions” If they all took the upward path, we should have a general conflagration."

"[W]hen anything becomes fire, something... equal... must cease to be fire, if the "exchange" is... just... and... we are assured by... the Erinyes (fr. 29)... that the sun does not take more than he gives. Of course there is... variation; but... strictly confined within limits, and is compensated in the long run by a variation in the other direction."

"It is much easier to find fragments which are on the face of them inconsistent with a general ."

"[T]he absence of anything to show that Herakleitos spoke of a general ... becomes more patent when we turn to the few fragments which are supposed to prove it. The favourite is fr. 24, where... Fire was Want and Surfeit. [I]t has a perfectly intelligible meaning on our interpretation... confirmed by fr. 36. [I]t seems... artificial to understand the Surfeit as referring to the fact that fire has burnt everything else up, and... more so to interpret Want as meaning... fire... has turned into a world. The next is fr. 26 where... fire... will judge and convict all things. There is nothing... to suggest... fire will judge... at once rather than in turn, and... the advance of fire and water... we have seen... is... limited... These appear to be the only passages... the Stoics and the Christian apologists could discover, and... cannot bear the weight of their conclusion... [T]here was certainly nothing more definite to be found."

"Plato’s contrast between Herakleitos and Empedokles ...is ...that, while Herakleitos said the One was always many, and the Many always one, Empedokles said the All was many and one by turns."

"[R]eal weariness is continuance in the same state (fr. 82), and... real rest, is change (fr. 83). Rest in any other sense is... dissolution (fr. 84). So they too are born once more."

"The living and the dead are always changing places (fr. 78)... not only to the souls that have become water, but to those that have become fire and are now guardian spirits."

"Everything is... the death of something else (fr. 64)."

"So, too... (fr. 67)... gods and men are... one. They live each others' life, and die each others' death. Those mortals that die the fiery death become immortal... [i.e.,] the guardians of the quick and the dead (fr. 123); and those immortals become mortal in their turn."

"The soul that has died from excess of moisture sinks down to earth; but from the earth comes water, and from water is once more exhaled a soul (fr. 68)."

"[T]he soul will be now living and now dead... it will only turn to fire or water... to recommence... its unceasing upward and downward path."

"[A]s summer and winter are one, and... reproduce one another by their "opposite tension," so do life and death... and so... youth and age (fr. 78)."

"Those who die the fiery... death, become... gods... in a different sense from that in which the one Wisdom is god. It is probable that the corrupt fragment 123 refers to this unexpected fate (fr. 122)..."

"The dry soul, that which has least moisture, is... best (fr. 74); but... preponderance of fire causes... a... different death... and wins "greater portions"... (fr. 101). ...[T]hose who fall in battle share their lot (fr. 102)."

"That is why it is... necessary... to quench wantonness (fr. 103); for whatever our heart’s desire insists on it purchases at the price of life... [i.e.,] the fire within us (fr. 105)."

"It is death... to souls to become water (fr. 68); but that is... what happens to souls which seek after pleasure... a moistening of the soul (fr. 72), as... in... the drunken man, who... has moistened his soul to... an extent that he does not know where he is going (fr. 73). Even in gentle relaxation over our cups, it is... difficult to hide folly... (fr. 108)."

"[I]n no soul are the fire and water... evenly balanced for long. One... acquires predominance, and the result... is death."

"The true Herakleitean doctrine doubtless was, that sleep was produced by the encroachment of moist, dark exhalations from the water in the body, which cause the fire to, burn low. In sleep, we lose contact with the fire in the world which is common to all, and retire to a world of our own (fr. 95). In a soul where the fire and water are evenly balanced, the equilibrium is restored in the morning by an equal advance of the bright exhalation."

"The locus classicus on this... is... Sextus Empiricus, which reproduces the account of the Herakleitean psychology given by Ainesidemos... (R. P. 41):— The natural philosopher is of opinion that what surrounds us is rational and endowed with consciousness. According to Herakleitos, when we draw in this divine reason by... respiration, we become rational. In sleep we forget, but at our waking we become conscious once more. For in sleep... the mind... is cut off from... that which surrounds us, and only our connexion... by... respiration is preserved as a... root (from which the rest may spring again); and, when... thus separated, it loses the power of memory... When we awake again... it looks out through the openings of the senses, as if through windows, and coming together with the surrounding mind, it assumes the power of reason. Just... as embers... brought near the fire, change and become red-hot, and go out when they are taken away... so does the portion of... mind... become irrational when... cut off, and... become of like nature to the whole... through the greatest number of openings. In this passage there is... a... large admixture of later... ideas. In particular... identification of "that which surrounds us" with the air... for Herakleitos can have known nothing of air, which in his day was regarded as a form of water... The reference to the pores or openings of the senses is probably foreign... for the theory of pores is due to Alkmaion. ...[T]he distinction between mind and body is far too sharply drawn. ...[T]he important rôle assigned to respiration may very well be Herakleitean; for we ... met with it ...in Anaximenes. ...[T]he striking simile of the embers which glow when ...near the fire is genuine (cf. fr. 77)."

"Man is subject to... in his "measures" of fire and water... [T]his gives rise to the alternations of sleeping and waking, life and death."

"We are just as much in perpetual flux as anything else in the world. We are and are not the same for two consecutive instants (fr. 81). The fire in us is perpetually becoming water, and the water earth; but, as the opposite process goes on simultaneously, we appear to remain the same."

"[T]he fire which animates man is subject to the "upward and downward path," just as much as the fire of the world. ..."All things are passing, both human and divine, upwards and downwards by exchanges.""

"Herakleitos... explained the world by man rather than man by the world. ...Aristotle implies that soul is identical with the dry exhalation, and this is ...confirmed by the fragments. Man is made... of... fire, water, and earth. But, just as in the macrocosm fire is... the one wisdom, so in the microcosm... fire alone is conscious. When it has left the body..., the mere earth and water, is... worthless (fr. 85)."

"Αll things are "exchanged" for fire and fire for all things (fr. 22), and this implies that for everything it takes, fire will give as much. “The sun will not exceed his measures” (fr. 29)."

"How is it that, in spite of this constant flux, things appear relatively stable? ...[I]t is owing to the observance of the "measures," in virtue of which the aggregate bulk of each form of matter in the long run remains the same, though its substance is constantly changing, Certain "measures" of the "ever-living fire" are always being kindled, while like "measures" are always going out (fr. 20)..."

"[O]ur best account of the Theophrastean of Herakleitos is the fuller of the two accounts... in Laertios Diogenes... as follows:— ...He held that Fire was the element, and that all things were an exchange for fire, produced by condensation and rarefaction. But he explains nothing clearly. All things were produced in opposition, and all things were in flux like a river. The all is finite and the world is one. It arises from fire, and is consumed again by fire alternately through all eternity in... cycles. This happens according to fate. That which leads to the becoming of the opposites is called War and Strife; that which leads to the final conflagration is Concord and Peace. He called change the upward and the downward path, and held that the world comes into being in virtue of this. When fire is condensed it becomes moist, and when compressed it turns to water; water being congealed turns to earth, and this he calls the downward path. And, again, the earth is in turn liquefied, and from it water arises, and from that everything else; for he refers almost everything to the evaporation from the sea. This is the path upwards. R. P. 36 He held, too, that exhalations arose both from the sea and the land; some bright and pure, others dark. Fire was nourished by the bright ones, and moisture by the others. He does not make it clear what is the nature of that which surrounds the world. He held, however, that there were bowls in it with the concave sides turned towards us, in which the bright exhalations were collected and produced flames. These were the heavenly bodies. The flame of the sun was the brightest and warmest; for the other heavenly bodies were more distant from the earth; and for that reason gave less light and heat. The moon, on the other hand, was nearer the earth; but it moved through an impure region. The sun moved in a bright and unmixed region, and at the same time was at just the right distance from us. That is why it gives more heat and light. The eclipses of the sun and moon were due to the turning of the bowls upwards, while the monthly phases of the moon were produced by a gradual turning of its bowl. Day and night, months and seasons and years, rains and winds, and things like these, were due to the different exhalations. The bright exhalation, when ignited in the circle of the sun, produced day, and the preponderance of the opposite exhalations produced night. The increase of warmth proceeding from the bright exhalation produced summer, and the preponderance of moisture from the dark exhalation produced winter. He assigns the causes of other things in conformity with this. As to the earth, he makes no clear statement about its nature, any more than he does about that of the bowls. These, then, were his opinions. R. P. 39 b."

"In the fragments... we find nothing about rarefaction and condensation. The expression used is "exchange" (fr. 22)... a very good name for... when fire gives out smoke and takes in fuel..."

"The Milesians held a similar view. The flux of Herakleitos was at most more unceasing and universal."

"Herakleitos held..., that any... thing, however stable in appearance, was merely a section in the stream, and... the matter composing it was never the same in any two consecutive moments... [T]he idea was not... novel, and... hardly the central point in the system of Herakleitos."

"Aristotle says the same... "All things are in motion," "nothing steadfastly is.""

"Plato... expresses the idea... clearly. "Nothing ever is, everything is becoming"; "All things are in motion like streams"; "All things are passing, and nothing abides"; "Herakleitos says somewhere that all things pass and naught abides; and, comparing things to the current of a river, he says that you cannot step twice into the same stream". (cf. fr. 41)—these are the terms in which he describes the system."

"This theory is usually summed up... "All things are flowing"... though... it cannot be proved that this is a quotation from Herakleitos."

"This necessarily brings... a certain way of looking at the change and movement of the world. ...It follows that ...reality is like an ever-flowing stream ...nothing is ever at rest ...The substance of ...things ...is in constant change."

"The quantity of fire in a flame... appears to remain the same, the flame seems to be... a "thing"... yet the substance... is continually changing. ...[P]assing away in smoke ...its place ...always being taken by fresh ...fuel that feeds it. ...If we regard the world as an "ever-living fire" (fr. 20), we can understand ...it ...always becoming all things, while all things are always returning to it."

"[T]his made it necessary for him to seek... a new primary substance... not merely... out of which the diversified world... might... be made, or from which opposites could be "separated out," but... which of its own nature would pass into everything else, while everything else would pass in turn into it. This he found in Fire..."

"This identity had been realised... by the Milesians, but they... found a difficulty in the difference. Anaximander had treated the strife of opposites as an "injustice," and... Herakleitos set himself to show... it was the highest justice (fr, 62)."

"The identity ...as consisting in difference is simply that of the primary substance in all its manifestations."

"We must be careful... not to imagine that Herakleitos thus discovered... a logical principle. The identity in and through difference... was purely physical; logic did not yet exist, and... the principle of identity had not been formulated, it would have been impossible to protest against an abstract application of it."

"[T]he differentiation of the one into many, and the integration of the many into one, are both eternal and simultaneous, and... this is the ground upon which... Herakleitos is contrasted with... Empedokles. ...[A]ccording to Plato, Herakleitos taught that reality was at once many and one."

"[In] Plato.., the Sophist (242 d), the Eleatic stranger, after explaining how the maintained that what we call many is really one, proceeds:— But certain Ionian and (at a later date) certain Sicilian Muses remarked that it was safest to unite these two things, and to say that reality is both many and one, and is kept together by Hate and Love. "For," say the more severe Muses, "in its division it is always being brought together" (cf. fr. 59); while the softer Muses relaxed the requirement that this should always be so, and said that the All was alternately one and at peace through the power of Aphrodite, and many and at war with itself because of something they called Strife. ...the Ionian Muses stand ...for Herakleitos, and the Sicilian for Empedokles."

"Anaximander had taught... the opposites were separated... from the Boundless, but passed away into it once more... paying the penalty for... unjust encroachments on one another. It is... implied... there is something wrong in the war of opposites, and... existence of the Many is a breach in the unity of the One. ...Herakleitos proclaimed ...there is no One without the Many, and no Many without the One. The world is at once one and many, and ...the "opposite tension" of the Many ...constitutes the unity of the One."
