c. He further made this fire to be a real process; because its reality is for itself the whole process, the moments have become concretely determined. Fire, as the metamorphosis of bodily things, is the transformation and exhalation of the determinate; for this process Heraclitus used a particular word—evaporation (ἀναθυμίασις)—but it is rather transition. Aristotle (De anim. I. 2) says of Heraclitus in this regard, that, according to his view, “the soul is the principle because it is evaporation, the origination of everything; it is what is most incorporeal and always in a state of flux.” This is quite applicable to the primary principle of Heraclitus.
Furthermore he determined the real process in its abstract moments by separating two sides in it—“the way upwards (ὁδὸς ἄνω) and the way downwards (ὁδὸς κάτω)”—the one being division, in that it is the existence of opposites, and the other the unification of these existent opposites. Corresponding to these, he had, according to Diogenes (IX. 8), the further determinations “of enmity and strife (πόλεμος, ἔρις), and friendship and harmony (ὁμολογία, εἰρήνη); of these two, enmity and strife is that which is the principle of the origination of differences; but what leads to combustion is harmony and peace.” In enmity amongst men, the one sets himself up independently of the other, or is for himself and realizes himself; but unity and peace is sinking out of independence into indivisibility or non-reality. Everything is thre-fold and thereby real unity; nature is the never-resting, and the all is the transition out of the one into the other, from division into unity, and from unity into division.
The more detailed accounts of this real process are, in great measure, deficient and contradictory. In this connection, it is in some accounts[63] said of Heraclitus that he defined it thus: “Of the forms taken by fire there is first of all the sea, and then of it half is the earth and the other half the lightning flash (πρηστήρ),” the fire which springs up. This is general and very obscure. Diogenes Laertius (IX. 9) says: “Fire is condensed into moisture, and when concrete it becomes water; water hardens into earth and this is the way downwards. The earth then again becomes fluid, and from it moisture supervenes, and from this the evaporation of the sea, from which all else arises; this is the way upwards. Water divides into a dark evaporation, becoming earth, and into what is pure, sparkling, becoming fire and burning in the solar sphere; what is fiery becomes meteors, planets and stars.” These are thus not still, dead stars, but are regarded as in Becoming, as being eternally productive. We thus have, on the whole, a metamorphosis of fire. These oriental, metaphorical expressions are, however, in Heraclitus not to be taken in their strictly sensuous signification, and as if these changes were present to the outward observation; but they depict the nature of these elements by which the earth eternally creates its suns and comets.
Nature is thus a circle. With this in view, we find Heraclitus, according to Clement of Alexandria (Strom. V. 14, p. 711), saying: “The universe was made neither by God nor man, but it ever was and is, and will be, a living fire, that which, in accordance with its laws, (μέτρῳ) kindles and goes out.” We now understand what Aristotle says of the principle being the soul, since the latter is evaporation; that is to say, fire, as this self-moving process of the world, is the soul. Another statement follows, which is also found in Clement of Alexandria (Strom. VI. 2, p. 746): “To souls (to the living) death is the becoming water; to water death is the becoming earth; on the other hand from earth, water arises, and from water, the soul.” Thus, on the whole, this process is one of extinction, of going back from opposition into unity, of the re-awakening of the former, and of issuing forth from one. The extinction of the soul, of the fire in water, the conflagration that finally results, some, and amongst others, Diogenes Laertius (IX. 8), Eusebius (Præp. Evang. XIV. 3) and Tennemann (Vol. I. p. 218), falsely assert to be a conflagration of the world. What Heraclitus is said to have spoken of as a conflagration of this world, was thought to be an imaginary idea that after a certain time—as, according to our ideas, at the end of the world—the world would disappear in flames. But we see at once from passages which are most clear,[64] that this conflagration is not meant, but that it is the perpetual burning up as the Becoming of friendship, the universal life and the universal process of the universe. In respect of the fact that, according to Heraclitus, fire is the animating, or the soul, we find in Plutarch (De esu. carn. I. p. 995, ed. Xyl.) an expression which may seem odd, namely, that “the driest soul is the best.” We certainly do not esteem the most moist the best, but, on the other hand, the one which is most alive; however dry here signifies fiery and thus the driest soul is pure fire, and this is not lifeless but life itself.
These are the principal moments of the real life-process; I will stop here a moment because we here find expressed the whole Notion of speculative reflection regarding Nature. In this Notion, one moment and one element goes over into the other; fire becomes water, water earth and fire. The contention about the transmutation and immutability of the elements is an old one; in this conception the ordinary, sensuous science of nature separates itself from natural philosophy. In the speculative point of view, which is that of Heraclitus, the simple substance in fire and the other elements in itself becomes metamorphosed; in the other, all transition is abolished and only an external separation of what is already there is maintained. Water is just water, fire is fire, &c. If the former point of view upholds transmutation, the latter believes in the possibility of demonstrating the opposite; it no longer, indeed, maintains water, fire, &c., to be simple realities, for it resolves them into hydrogen, oxygen, &c., but it asserts their immutability. It justly asserts that what is asserted and implied in the speculative point of view, must also have the truth of actuality; for if to be the speculative means to be the very nature and principle of its elements, this must likewise be present. We are wrong in representing the speculative to be something existent only in thought or inwardly, which is no one knows where. It is really present, but men of learning shut their eyes to it because of their limited point of view. If we listen to their account, they only observe and say what they see; but their observation is not true, for unconsciously they transform what is seen through their limited and stereotyped conception; the strife is not due to the opposition between observation and the absolute Notion, but between the one Notion and the other. They show that changes—such as that of water into earth—are non-existent. Even in modern times this transformation was indeed maintained, for when water was distilled, a residuum of earth was found. On this subject, however, Lavoisier carried on a number of very conclusive researches; he weighed all the receptacles, and it was shown that the residuum proceeded from the vessels. There is a superficial process that does not carry us beyond the determinate nature of substance. They say in reference to it, “water does not change into air but only into moisture, and moisture always condenses back into water again.” But in this they merely fix on a one-sided, insufficient process, and give it out to be the absolute process. In the real process of nature they, however, found by experience that the crystal dissolved gives water, and in the crystal, water is lost and solidifies, or becomes the so-called water of crystallization; they found that the evaporation of the earth is not to be found as moisture, in outward form in the air, for air remains quite pure, or hydrogen entirely disappears in pure air; they have sought in vain to find hydrogen in the atmospheric air. Similarly they discovered that quite dry air in which they can show neither moisture nor hydrogen, passes into mist, rain, &c. These are their observations, but they spoilt all their perceptions of changes by the fixed conception which they brought with them of whole and part, and of consistence out of parts, and of the previous presence as such, of what manifests itself in coming into existence. When the crystal dissolved reveals water, they say, “it is not that water has arisen, for it was already present there.” When water in its decomposition reveals hydrogen and oxygen, that means, according to them, “these last have not arisen for they were already there as such, as the parts of which the water subsists.” But they can neither demonstrate water in crystal nor oxygen and hydrogen in water, and the same is true of “latent heat.” As we find in all expression of perception and experience, as soon as men speak, there is a Notion present; it cannot be withheld, for in consciousness there always is a touch of universality and truth. For the Notion is the real principle, but it is only to cultured reason that it is absolute Notion, and not if it remains, as here, confined in a determinate form. Hence these men necessarily attain to their limits, and they are troubled because they do not find hydrogen in air; hygrometers, flasks full of air brought down from heights by an air-balloon, do not show it to exist. And similarly the water of crystallization is no longer water, but is changed into earth.
To come back to Heraclitus, there is only one thing wanting to the process, which is that its simple principle should be recognized as universal Notion. The permanence and rest which Aristotle gives, may be missed. Heraclitus, indeed, says that everything flows on, that nothing is existent and only the one remains; but that is the Notion of the unity which only exists in opposition and not of that reflected within itself. This one, in its unity with the movement of the individuals, is the genus, or in its infinitude the simple Notion as thought; as such, the Idea has still to be determined, and we shall thus find it again as the νοῦς of Anaxagoras. The universal is the immediate simple unity in opposition which goes back into itself as a process of differences; but this is also found in Heraclitus; he called this unity in opposition Fate (εἱμαρμένη) or Necessity.[65] And the Notion of necessity is none other than this, that determinateness constitutes the principle of the existent as individual, but in that very way, relates it to its opposite: this is the absolute “connection (λόγος) that permeates the Being of the whole.” He calls this “the ethereal body, the seed of the Becoming of everything”;[66] that to him is the Idea, the universal as reality, as process at rest.
[3. Relation of the Principle to Consciousness.] There is still something else to consider, and that is what position in this principle Heraclitus gives to consciousness; his philosophy has, on the whole, a bent towards a philosophy of nature, for the principle, although logical, is apprehended as the universal nature-process. How does this λόγος come to consciousness? How is it related to the individual soul? I shall explain this here in greater detail: it is a beautiful, natural, childlike manner of speaking truth of the truth. The universal and the unity of the principle of consciousness and of the object, and the necessity of objectivity, make their first appearance here. Several passages from Heraclitus are preserved respecting his views of knowledge. From his principle that everything that is, at the same time is not, it immediately follows that he holds that sensuous certainty has no truth; for it is the certainty for which something exists as actual, which is not so in fact. Not this immediate Being, but absolute mediation, Being as thought of, Thought itself, is the true Being. Heraclitus in this relation says of sensuous perception—according to Clement of Alexandria—(Strom. III. 3, p. 520): “What we see waking is dead, but what we see sleeping, a dream,” and in Sextus (adv. Math. VII. 126, 127), “Men’s eyes and ears are bad witnesses, for they have barbarous souls. Reason (λόγος) is the judge of truth, not the arbitrary, but the only divine and universal judge”—this is the measure, the rhythm, that runs through the Being of everything. Absolute necessity is just the having the truth in consciousness; but every thought, or what proceeds from the individual, every relation in which there is only form and which has the content of the ordinary idea, is not such; what is so is the universal understanding, the developed consciousness of necessity, the identity of subjective and objective. Heraclitus says in this connection, according to Diogenes (IX. 1): “Much learning (πολυμαθίν) does not instruct the mind, else it had instructed Hesiod, Pythagoras, Xenophanes and Hecatæus. The only wisdom is to know the reason that reigns over all.”
Sextus (adv. Math. VII. 127-133), further describes the attitude of the subjective consciousness, of particular reason, to the universal, to this nature-process. That attitude has still a very physical appearance, resembling the state of mind we suppose in men who are mad or asleep. The waking man is related to things in a universal way, which is in conformity with the relation of the things and is the way in which others also regard them, and yet he still retains his independence. If, and in so far as I stand in the objectively intelligent connection of this state of mind, I am, just because of this externality, in finitude; but waking, I have the knowledge of the necessity of a connection in the form of objectivity, the knowledge of the universal existence, and thus the Idea in finite form. Sextus puts this in definite form: “Everything that surrounds us is logical and intelligent”—yet not therefore accompanied by consciousness. “If we draw this universal reality through our breath, we shall be intelligent, but we are so waking only, sleeping we are in oblivion.” The waking consciousness of the outer world, what belongs to the sphere of the understanding, is rather what may be called a condition; but here it is taken as the whole of rational consciousness. “For in sleep the channels of feeling are closed and the understanding that is in us is prevented from uniting (συμφυΐας) with the surroundings; the breath is the only connection (πρόσφυσις) maintained, and it may be compared to a root.” This breath is thus distinguished from the universal breath, i.e. from the being of another for us. Reason is this process with the objective: when we are not in connection with the whole, we only dream. “Separated, the understanding loses the power of consciousness (μνημονικὴν δύναμιν) that it formerly had.” The mind as individual unity only, loses objectivity, is not in individuality universal, is not the Thought which has itself as object. “In a waking condition, however, the understanding—gazing through the channels of sense as though it were through a window, and forming a relationship with the surroundings—maintains the logical power.” We here have the ideal in its native simplicity. “In the same way as coals which come near fire, themselves take fire, but apart from it, go out, the part which is cut off from the surroundings in our bodies becomes, through the separation, almost irrational.” This confutes those who think that God gives wisdom in sleep or in somnambulism. But in connection with the many channels it becomes similar to the whole. This whole, the universal and divine understanding, in unity with which we are logical, is, according to Heraclitus, the essence of truth. Hence that which appears as the universal to all, carries with it conviction, for it has part in the universal and divine Logos, while what is subscribed to by an individual carries with it no conviction from the opposite cause. He says in the beginning of his book on Nature: “Since the surroundings are reason, men are irrational both before they hear and when they first hear. For since what happens, happens according to this reason, they are still inexperienced when they search the sayings and the works which I expound, distinguishing the nature of everything and explaining its relations. But other men do not know what they do awake, just as they forget what they do in sleep.” Heraclitus says further: “We do and think everything in that we participate in the divine understanding (λόγος). Hence we must follow the universal understanding. But many live as if they had an understanding (φρόνησιν) of their own; the understanding is, however, nothing but interpretation” (being conscious) “of the manner in which all is ordered. Hence in so far as we participate in the knowledge (μνήμης) of it, we are in the truth; but in so far as we are singular (ἰδιάσωμεν) we are in error.” Great and important words! We cannot speak of truth in a truer or less prejudiced way. Consciousness as consciousness of the universal, is alone consciousness of truth; but consciousness of individuality and action as individual, an originality which becomes a singularity of content or of form, is the untrue and bad. Wickedness and error thus are constituted by isolating thought and thereby bringing about a separation from the universal. Men usually consider, when they speak of thinking something, that it must be something particular, but this is quite a delusion.
However much Heraclitus may maintain that there is no truth in sensuous knowledge because all that exists is in a state of flux, and that the existence of sensuous certainty is not while it is, he maintains the objective method in knowledge to be none the less necessary. The rational, the true, that which I know, is indeed a withdrawal from the objective as from what is sensuous, individual, definite and existent; but what reason knows within itself is necessity or the universal of being; it is the principle of thought, as it is the principle of the world. It is this contemplation of truth that Spinoza in his Ethics (P. II. propos. XLIV., coroll. II. p. 118, ed. Paul), calls “a contemplation of things in the guise of eternity.” The being-for-self of reason is not an objectless consciousness, or a dream, but a knowledge, that which is for itself; but this being-for-self is awake, or is objective and universal, i.e. is the same for all. The dream is a knowledge of something of which I alone know; fancy may be instanced as just such a dream. Similarly it is by feeling that something is for me alone, and that I have something in me as in this subject; the feeling may profess to be ever so elevated, yet it really is the case that for me as this subject, it is what I feel, and not an object independent of me. But in truth, the object is for me something essentially free, and I am for myself devoid of subjectivity; similarly this object is no imaginary one made an object by me alone, but is in itself a universal.
There are, besides, many other fragments of Heraclitus, solitary expressions, such as his saying, “men are mortal gods, and gods immortal men; living is death to the former and dying is their life.”[67] Life is the death of the gods, death is the life of the gods; the divine is the rising through thought above mere nature which belongs to death. Hence Heraclitus also says, according to Sextus (adv. Math. VII., 349): “the power of thinking is outside the body,” which, in a remarkable way, Tennemann makes into: “outside of men.” In Sextus (Pyrrh. Hyp. III. 24, § 230) we further read: “Heraclitus says that both life and death are united in our life as in our death; for if we live, our souls are dead and buried in us, but if we die, our souls arise and live.” We may, in fact, say of Heraclitus what Socrates said: “What remains to us of Heraclitus is excellent, and we must conjecture of what is lost, that it was as excellent.” Or if we wish to consider fate so just as always to preserve to posterity what is best, we must at least say of what we have of Heraclitus, that it is worthy of this preservation.
