Chapter VIII. Philosophers’ Opinions Concerning the System of the Universe

[PLUTARCH] ‘Thales, it is said, was the first of all who supposed that water was the original element of the universe, for that all things spring from it and return to it.

‘After him Anaximander, who had been a companion of Thales, said that the Infinite contained the whole cause of both the generation and decay of all things, and out of it he says that the heavens, and, generally, all the worlds, which are infinite in number, have been brought into distinct form. He declared that decay and, long before that, generation originated in the revolution of all these worlds from infinite ages. The earth, he says, is in figure cylindrical, and its depth a third part of its breadth. He says too that the eternal generative force of heat and cold was separated at the generation of this world, and that from it a kind of sphere of flame grew round the atmosphere of the earth as bark round a tree; and that when this flame was rent asunder and shut off into certain orbits, the sun and moon and stars came into existence. Further, he says that man at first was generated d from animals of other kinds, because while the other animals quickly find food of themselves, man alone needs to be nursed for a long time; and for this reason, being such as he is, he could not in the beginning have been kept alive. These then are the opinions of Anaximander.

‘But Anaximenes, it is said, declared the air to be the first element of the universe, and that this is in its generic nature infinite, but is differentiated by the qualities attached to it, and that all things are generated by virtue of a certain condensation and subsequent rarefaction of this air. Its motion however subsists eternally, and when the air was compressed, first, he said, the earth was produced, and was very broad, and therefore according to reason floated upon the air; and the sun, and moon, and other heavenly bodies were originally produced out of earth. He declares, for instance, that the sun is earth, but because of its swift motion it has a great supply of heat.

‘Xenophanes of Colophon has proceeded by a way of his own, diverging from all who have been previously mentioned, for he leaves neither generation nor decay, but says that the All is always alike. For, says he, if it were to begin to be, it must previously not be; but Non-being cannot begin to be, nor can Non-being make anything, nor from Non-being can anything begin to be.

‘He declares also that the senses are fallacious, and with them altogether disparages even reason itself. Also he declares that the earth being continuously carried down little by little in time passes away into the sea. He says also that the sun is formed from a gathering of many small sparks. With regard to the gods; also he declares that there is no ruling power among them; for it is not right that any of the gods should be under a master: and none of them needs anything at all from any; and that they hear and see universally and not partially.

‘Also he declares that the earth is infinite, and not surrounded; by air on every side; and that all things are produced out of earth: the sun, however, and the other heavenly bodies he says ‘are produced out of the clouds.

‘But Parmenides the Eleatic, the companion of Xenophanes, both claimed to hold his opinions and at the same time tried to establish the opposite position. For he declares that in real truth the All is eternal and motionless; for he says it is

“Sole, of sole kind, unmoving, uncreated”

and that generation belongs to the things which upon a false assumption are thought to exist, and he denies the truth of the sensual perceptions. He says too that if anything subsists besides Being, this is Non-being, and Non-being does not exist in the universe. Thus he concludes that Being is uncreated. The earth, he says, has arisen from the dense air having settled down.

‘Zeno the Eleatic put forth nothing properly his own, but discussed these opinions more at large.

‘Democritus of Abdera supposed that the All is infinite, because there was none who could possibly have framed it: he further says that it is unchangeable; and generally, everything being such as it is, he expressly asserts that the causes of the processes now going on have no beginning, but all things absolutely, past, present, and to come, are wholly fixed beforehand by necessity from infinite time. Of the generation of the sun and moon he says, that they moved in their separate courses, when as yet they had no natural heat at all, nor generally any brightness, but on the contrary were assimilated to the nature of the earth; for each of them had been produced earlier when the world was as yet in some peculiar rudimentary condition, and afterwards, when the orbit round the sun became enlarged, the fire was included in it.

‘Epicurus son of Neocles, an Athenian, endeavours to suppress the vain conceit about gods: but also says that nothing is produced out of Non-being, because the All always was and always will be such as it is; that nothing new is brought to pass in the All because of the infinite time which has already passed; that all is body, and not only unchangeable, but also infinite; that the summum bonum is pleasure.

‘Aristippus of Gyrene says that pleasure is the summum bonum, and pain the worst of evils; but all other physiology he excludes by saying that the only useful thing is to inquire

“What for your home is evil and what good.” [1]

‘Empedocles of Agrigentum made four elements, fire, water, air, and earth, and their cause friendship and enmity. There was first the mixture of the elements, out of which, he says, the air was separated and diffused all around; and next to the air the fire leaped out, and having no other place was driven upwards by the freezing of the air. And there are two hemispheres, he says, moving in a circle round the earth, the one wholly of fire, the other of air and a little fire mixed, which he supposes to be night; and the beginning of their motion resulted from its having happened when the fire predominated in the combination. And the sun is in its nature not fire, but a reflexion of fire, like the reflexion formed from water. The moon, he says, was formed separately by itself out of the air left by the fire; for this air froze just like hail: but its light it has from the sun. The ruling power, he says, is neither in the head nor in the breast, but in the blood; whence also he thinks that in whatever part of the body this ruling power (the blood) is more largely diffused, in that part men excel.

‘Metrodorus of Chios says that the All is eternal, because if it were created it would have come from Non-being; and infinite, because eternal, for it had no first principle to start from, nor any limit, nor end. But neither does the All partake of motion; for it cannot be moved without changing its place; and a change of place must of necessity be either into plenum or into vacuum. The air being condensed makes clouds, then water, which also flowing down upon the sun extinguishes it: and it is rekindled again by evaporation. And in time the sun is made solid by the dryness, and forms stars out of the clear water, and from being extinguished and rekindled makes night and day, and eclipses generally.

‘Diogenes of Apollonia supposes that air is the primary element, that all things are in motion, and that the worlds are infinite. His cosmogony is as follows: when the All was in motion, and was becoming in one part rare and in another dense, where the dense part happened to meet it formed a concretion, and so the other parts on the same principle; and the lightest having taken the highest position produced the sun.’

Such is the judgement of the all-wise Greeks, those, forsooth, who were entitled physicists and philosophers, concerning the constitution of the All and the original cosmogony; in which they did not assume any creator or maker of the universe, nay, they made no mention of God at all, but referred the cause of the All solely to irrational impulse and spontaneous motion.

So great also is their mutual opposition; for in no point have they agreed one with another, but have filled the whole subject with strife and discord. Wherefore the admirable Socrates used to convict them all of folly, and to say that they were no better than madmen, that is, if you think Xenophon a satisfactory witness, when in the Memorabilia he speaks thus:

[XENOPHON] ‘But no one ever yet either saw Socrates do, or heard him say, anything impious or irreligious. For even concerning the nature of all things, or other such questions, he did not discourse, as most did, speculating what is the nature of the cosmos, as the sophists call it, and by what necessary forces the heavenly bodies are each produced, but he even used to represent those who troubled their minds about such matters as talking folly.’[2]

And presently he adds:

‘And he used to wonder, that it was not manifest to them, that it is impossible for men to discover these things; since even those who prided themselves most highly on discoursing of these subjects did not hold the same opinions one with another, but behaved to each other like mad people. For as among madmen some do not fear even things that should be feared, and others fear what is not at all fearful; ... so of those who trouble themselves about the nature of all things, some think that Being is one only, others that it is an infinite multitude; and some that all things are ever in motion, but others that nothing ever can be moved: and some that all things are created and perish, but others that nothing ever can either be created or perish.’[3]

So says Socrates, according to the testimony of Xenophon. And Plato also agrees with this account in his dialogue Concerning the Soul, describing him as thus speaking:

[PLATO] ‘For in my youth, Cebes, said he, I myself had a wonderful longing for this kind of wisdom which they call Physical Research: it seemed to me a magnificent thing to know the causes of everything, why each comes into being, and why it perishes, or why it exists. And I was constantly turning my mind this way and that, in examining first such questions as these:—Is it when hot and cold have assumed a kind of putrefaction, as some used to say,—is it then that living things are bred and nourished? And is the blood that by which we think, or the air, or the fire? Or is it none of these, but is the brain that which supplies the sensation of sight, and hearing, and smell? And from these might come memory and opinion, and from memory and opinion, when they have reached a settled state, in the same manner knowledge arises. And then again I speculated on their decay, and the changes to which the heaven and the earth are subject, and at last it seemed to me that I was of all things in the world the least fitted by nature for such speculation. And I will tell you a good proof of it: I was so utterly blinded by the mere inquiry, that even what I clearly understood before, at least as I and others thought, I then unlearned,— even what I thought I knew before.’[4]

So said Socrates, that very man so celebrated by all the Greeks. When, therefore, even this great philosopher had such an opinion of the physiological doctrines of those whom I have mentioned, I think that we too have with good reason deprecated the atheism of them all, since their polytheistic error also seems not to be unconnected with the opinions already mentioned. This, however, shall be proved on the proper occasion, when I shall show that Anaxagoras is the first of the Greeks mentioned as having set mind to preside over the cause of the All.

But now pass on with me to Diodorus, and consider what he narrates concerning the primitive theology of mankind.[5]
