89. To sum up. What is, is a finite, spherical, motionless corporeal plenum, and there is nothing beyond it. The appearances of multiplicity and motion, empty space and time, are illusions. We see from this that the primary substance of which the early cosmologists were in search has now become a sort of “thing in itself.” It never quite lost this character again. What appears later as the elements of Empedokles, the so-called “homoeomeries” of Anaxagoras and the atoms of Leukippos and Demokritos, is just the Parmenidean “being.” Parmenides is not, as some have said, the “father of idealism”; on the contrary, all materialism depends on his view of reality.

The beliefs of “mortals.”

90. It is commonly said that, in the Second Part of his poem, Parmenides offered a dualistic theory of the origin of things as his own conjectural explanation of the sensible world, or that, as Gomperz says, “What he offered were the Opinions of Mortals; and this description did not merely cover other people’s opinions. It included his own as well, as far as they were not confined to the unassailable ground of an apparent philosophical necessity.”[[454]] Now it is true that in one place Aristotle appears to countenance a view of this sort, but nevertheless it is an anachronism.[[455]] Nor is it really Aristotle’s view. He was perfectly well aware that Parmenides did not admit the existence of “not-being” in any degree whatever; but it was a natural way speaking to call the cosmology of the Second Part of the poem that of Parmenides. His hearers would understand at once in what sense this was meant. At any rate, the Peripatetic tradition was that Parmenides, in the Second Part of the poem, meant to give the belief of “the many.” This is how Theophrastos put the matter, and Alexander seems to have spoken of the cosmology as something which Parmenides himself regarded as wholly false.[[456]] The other view comes from the Neoplatonists, and especially Simplicius, who very naturally regarded the Way of Truth as an account of the intelligible world, and the Way of Opinion as a description of the sensible. It need hardly be said that this is almost as great an anachronism as the Kantian parallelism suggested by Gomperz.[[457]] Parmenides himself tells us in the most unequivocal language that there is no truth at all in the theory which he expounds, and he gives it merely as the belief of “mortals.” It was this that led Theophrastos to speak of it as the opinion of “the many.”

His explanation however, though preferable to that of Simplicius, is not convincing either. “The many” are as far as possible from believing in an elaborate dualism such as Parmenides expounded, and it is a highly artificial hypothesis to assume that he wished to show how the popular view of the world could best be systematised. “The many” would hardly be convinced of their error by having their beliefs presented to them in a form which they would certainly fail to recognise. This, indeed, seems the most incredible interpretation of all. It still, however, finds adherents, so it is necessary to point out that the beliefs in question are called “the opinions of mortals” simply because the speaker is a goddess. Further, we have to note that Parmenides forbids two ways of research, and we have seen that the second of these, which is also expressly ascribed to “mortals,” must be the system of Herakleitos. We should surely expect, then, to find that the other way too is the system of some contemporary school, and it seems hard to discover any of sufficient importance except the Pythagorean. Now it is admitted by every one that there are Pythagorean ideas in the Second Part of the poem, and it is therefore to be presumed, in the absence of evidence to the contrary, that the whole system comes from the same source. It does not appear that Parmenides said any more about Herakleitos than the words to which we have just referred, in which he forbids the second way of inquiry. He implies, indeed, that there are really only two ways that can be thought of, and that the attempt of Herakleitos to combine them was futile.[[458]] In any case, the Pythagoreans were far more serious opponents at that date in Italy, and it is certainly to them that we should expect Parmenides to define his attitude.

It is still not quite clear, however, why he should have thought it worth while to put into hexameters a view which he believed to be false. Here it becomes important to remember that he had been a Pythagorean himself, and that the poem is a renunciation of his former beliefs. In such cases men commonly feel the necessity of showing where their old views were wrong. The goddess tells him that he must learn of those beliefs also “how men ought to have judged that the things which seem to them really are.”[[459]] That is clear so far; but it does not explain the matter fully. We get a further hint in another place. He is to learn these beliefs “in order that no opinion of mortals may ever get the better of him” (fr. [8], 61). If we remember that the Pythagorean system at this time was handed down by oral tradition alone, we shall perhaps see what this means. Parmenides was founding a dissident school, and it was quite necessary for him to instruct his disciples in the system they might be called upon to oppose. In any case, they could not reject it intelligently without a knowledge of it, and this Parmenides had to supply himself.[[460]]

The dualist cosmology.

91. The view that the Second Part of the poem of Parmenides was a sketch of contemporary Pythagorean cosmology is, doubtless, incapable of rigorous demonstration, but it can, I think, be made extremely probable. The entire history of Pythagoreanism up to the end of the fifth century B.C. is certainly conjectural; but, if we find in Parmenides ideas which are wholly unconnected with his own view of the world, and if we find precisely the same ideas in later Pythagoreanism, the most natural inference will surely be that the later Pythagoreans derived these views from their predecessors, and that they formed part of the original stock-in-trade of the society to which they belonged. This will only be confirmed if we find that they are developments of certain features in the old Ionian cosmology. Pythagoras came from Samos, which always stood in the closest relations with Miletos; and it was not, so far as we can see, in his cosmological views that he chiefly displayed his originality. It has been pointed out above ([§ 53]) that the idea of the world breathing came from Anaximenes, and we need not be surprised to find traces of Anaximander as well. Now, if we were confined to what Aristotle tells us on this subject, it would be almost impossible to make out a case; but his statements require, as usual, to be examined with a certain amount of care. He says, first of all, that the two elements of Parmenides were the Warm and the Cold.[[461]] In this he is so far justified by the fragments that, since the Fire of which Parmenides speaks is, of course, warm, the other “form,” which has all the opposite qualities, must of necessity be cold. But, nevertheless, the habitual use of the terms “the warm” and “the cold” is an accommodation to Aristotle’s own system. In Parmenides himself they were simply one pair of attributes amongst others.

Still more misleading is Aristotle’s identification of these with Fire and Earth. It is not quite certain that he meant to say Parmenides himself made this identification; but, on the whole, it is most likely that he did, and Theophrastos[Theophrastos] certainly followed him in this.[[462]] It is another question whether it is accurate. Simplicius, who had the poem before him ([§ 85]), after mentioning Fire and Earth, at once adds “or rather Light and Darkness”;[[463]] and this is suggestive enough. Lastly, Aristotle’s identification of the dense element with “what is not,”[[464]] the unreal of the First Part of the poem, is not very easy to reconcile with the view that it is earth. On the other hand, if we suppose that the second of the two “forms,” the one which should not have been “named,” is the Pythagorean Air or Void, we get a very good explanation of Aristotle’s identification of it with “what is not.” We seem, then, to be justified in neglecting the identification of the dense element with earth for the present. At a later stage, we shall be able to see how it may have originated.[[465]] The further statement of Theophrastos, that the Warm was the efficient cause and the Cold the material or passive,[[466]] is intelligible enough if we identify them with the Limit and the Unlimited respectively; but is not, of course, to be regarded as historical.

We have seen that Simplicius, with the poem of Parmenides before him, corrects Aristotle by substituting Light and Darkness for Fire and Earth, and in this he is amply borne out by the fragments which he quotes. Parmenides himself calls one “form” Light, Flame, and Fire, and the other Night, and we have now to consider whether these can be identified with the Pythagorean Limit and Unlimited. We have seen good reason to believe ([§ 58]) that the idea of the world breathing belonged to the earliest form of Pythagoreanism, and there can be no difficulty in identifying this “boundless breath” with Darkness, which stands very well for the Unlimited. “Air” or mist was always regarded as the dark element.[[467]] And that which gives definiteness to the vague darkness is certainly light or fire, and this may account for the prominence given to that element by Hippasos.[[468]] We may probably conclude, then, that the Pythagorean distinction between the Limit and the Unlimited, which we shall have to consider later (Chap. VII.), made its first appearance in this crude form. If, on the other hand, we identify darkness with the Limit, and light with the Unlimited, as most critics do, we get into insuperable difficulties.
