Empedocles, a native of the Greek city of Akragas in Sicily, was born probably about 493 B.C. and may have lived until about 433. His activities and his character alike seem to have been extraordinarily various. He was an aristocrat and also a champion of the democracy. He was offered and declined the kingship of Akragas. He was exiled and recited at Olympia his poem "The Purifications," in which he claimed to be a god. He was a keen observer — much more of a "scientist" than Parmenides — and he was also a kind of magician. He was a considerable poet and one of the founders of the new art of rhetorical and balanced prose. He had an important influence on medicine. He was an evolutionist and may be credited with the invention of the theory of "the survival of the fittest." He seems to have followed, at least to some extent, the Pythagorean way of life. "Wretches," he exclaims, "utter wretches, keep your hands from beans!" Some idea of his own notion of himself may be gained from another passage from the "Purifications".
112. Friends, that inhabit the great town looking down on the yellow rock of Akragas, up by the citadel, busy in goodly works, harbours of honour for the stranger, men unskilled in meanness, all hail. I go about among you an immortal god, no mortal now, honoured among all as is meet, crowned with fillets and flowery garlands. Straightway, whenever I enter with these in my train, both men and women, into the flourishing towns, is reverence done me; they go after me in countless throngs, asking of me what is the way to gain; some desiring oracles, while some, who for many a weary day have been pierced by the grievous pangs of all manner of sickness, beg to hear from me the word of healing.
We may notice here, apart from the claim to divinity, a great confidence in the power of wisdom to bring about results. And in fact Empedocles' theory of the four (or six) elements has proved very much more capable of useful development than have the various theories of "the One."
His philosophy is expressed in the poem "On Nature," of which 350 verses survive. His problem, it seems, was, while repairing the theory of Parmenides about "what is," to reconcile it with the apparent facts of change and of motion. And (though Burnet does not accept this view) his method appears to be based on a kind of compromise between Parmenides and Heraclitus. He accepts the idea of the permanency of "what is," but insists also on the permanency of a "process." In doing so he abandons the original Milesian hypothesis of a single substratum and comes forward with the view that the world is composed not of one "stuff" but of four "roots" or elements — fire, air, water and earth. These, as seems natural to a person of his temperament, are given divine names, though they are examined both experimentally and logically. Three of these "roots" had already been put forward as the ultimate reality by Empedocles' predecessors. In adding earth to the list and in asserting the existence of four elements rather than one "stuff," he may have been actuated simply by a kind of common sense; and those who, whether from a logical or an aesthetic impulse, wish to see all things explained by one hypothesis must deplore the pluralism. Yet it was a pluralism which led to results and which, unlike the splendid monism of Parmenides, did, if not make, at least account for, sense. In a way, too, it was the first step towards the atomic theory. But more remarkable than the theory of the four "roots" is the theory which is intended to account for change and motion, for the process of development and dissolution. Here Empedocles proclaims the existence of two "things" which he calls Strife and Love. We should, without question, call these "things" "forces." As Sambursky says, "Empedocles was the first to distinguish matter from force." And this is probably true, though it may be possible to find some such distinction in Heraclitus. However, though the distinction is a real one, the fragments show that Empedocles himself was scarcely aware of it. His "forces" are to him material. They have weight, length and breadth. How he thought of them we do not know. But do we know how we think of our own "forces"?
Strife and Love, or, as we should say, attraction and repulsion, account for change and motion. The elements are compounded under their influence and their influence can be imagined in more dimensions than the "upward and downward path" of Heraclitus. The cyclical process of the "Sphere" in which we live can be imagined or demonstrated as follows. Love is the unifier and Strife the divider. Four distinct historical periods must follow each other.
Obviously the kind of world which we know can only exist in periods 2 and 4. There are good reasons for believing that Empedocles thought that our world is in period 2.
This theory was evidently worked out in great detail. Perhaps its most interesting applications are in the realm of biology. Empedocles' theory of sensation and of vision was to have a long future and was taken up both by Plato and Aristotle and by the atomists. The theory is that "effluences" come to us from things and by "fitting into the forces" of the various organs of sense communicate to us vision, taste, smell, etc.
In the following extracts (taken from Burnet) it has seemed advisable, however, to give more space to the general theory of this remarkable man than to his detailed applications of it.
6. Hear first the four roots of all things: shining Zeus, life-bringing Hera, Aidoneus and Nestis whose tear-drops are a well-spring to mortals.
8. And I shall tell thee another thing. There is no substance of any of all the things that perish, nor any cessation for them of baneful death. They are only a mingling and interchange of what has been mingled. Substance is but a name given to these things by men.
16. For even as they (Strife and Love) were aforetime, so too they shall be; nor ever, methinks, will boundless time be emptied of that pair.
17. I shall tell thee a twofold tale. At one time it grew to be one only out of many; at another, it divided up to be many instead of one. There is a double becoming of perishable things and a double passing away. The coming together of all things brings one generation into being and destroys it; the other grows up and is scattered as things become divided. And these things never cease continually changing places, at one time all uniting in one through Love, at another each borne in different directions by the repulsion of Strife. Thus, as far as it is their nature to grow into one out of many, and to become many once more when the one is parted asunder, so far they come into being and their life abides not. But, in-as-much as they never cease changing their places continually, so far they are ever immovable as they go round the circle of existence. . . .
But come, hearken to my words, for it is learning that increaseth wisdom. As I said before, when I declared the heads of my discourse, I shall tell thee a twofold tale. At one time it grew together to be one only out of many, at another it parted asunder so as to be many instead of one; Fire and Water and Earth and the mighty height of Air, dread Strife, too, apart from these, of equal weight to each, and Love in their midst, equal in length and breadth. Her do thou contemplate with thy mind, nor sit with dazed eyes. It is she that is known as being implanted in the frame of mortals. It is she that makes them have thoughts of love and work the works of peace. They call her by the names of Joy and Aphrodite. Her has no mortal yet marked moving round among them, but do thou attend to the undeceitful ordering of my discourse.
For all these are equal and alike in age, yet each has a different prerogative and its own peculiar nature, but they gain the upper hand in turn when the time comes round. And nothing comes into being besides these, nor do they pass away; for, if they had been passing away continually, they would not be now, and what could increase this All and whence could it come? How, too, could it perish, since no place is empty of these things? There are these alone; but, running through one another, they become now this, now that, and like things evermore.
35,36. But now I shall retrace my steps over the paths of song that I have travelled before, drawing from my saying a new saying. When Strife was fallen to the lowest depth of the vortex, and Love had reached to the centre of the whirl, in it do all things come together so as to be one only; not all at once, but coming together at their will each from different quarters; and, as they mingled, Strife began to pass out to the furthest limit. Yet many things remained unmixed, alternating with the things that were being mixed, namely, all that Strife not fallen yet retained; for it had not yet altogether retired perfectly from them to the outermost boundaries of the circle. Some of it still remained within, and some had passed out from the limbs of the All. But in proportion as it kept rushing out, a soft, immortal stream of blameless Love kept running in, and straightway those things became mortal which had been immortal before, those things were mixed that had before been unmixed, each changing its path. And, as they mingled, countless tribes of mortal creatures were scattered abroad endowed with all manner of forms, a wonder to behold.
57. On it (the earth) many heads sprung up without necks and arms wandered bare and bereft of shoulders. Eyes strayed up and down in want of foreheads.
60. Shambling creatures with countless hands.
61. Many creatures with faces and breasts looking in different directions were born; some, offspring of oxen with faces of men, while others, again, arose as offspring of men with the heads of oxen, and creatures in whom the nature of women and men was mingled, furnished with sterile parts.
