Plato and the Other Companions of Sokrates, 3rd ed. Volume 2

If the arguments whereby Sokrates proves the immortality of the soul are neither forcible nor conclusive, not fully satisfying even Simmias39 to whom they are addressed — the adverse arguments, upon the faith of which the doctrine was denied (as we know it to have been by many philosophers of antiquity), cannot be said to be produced at all. Simmias and Kebês are represented as Sokratic companions, partly Pythagoreans; desirous to find the doctrine true, yet ignorant of the proofs. Both of them are earnest believers in the pre-existence of the soul, and in the objective reality of Ideas or intelligible essences. Simmias however adopts in part the opinion, not very clearly explained, “That the soul is a harmony or mixture”: which opinion Sokrates refutes, partly by some other arguments, partly by pointing out that it is inconsistent with the supposition of the soul as pre-existent to the body, and that Simmias must make his election between the two. Simmias elects without hesitation, in favour of the pre-existence: which he affirms to be demonstrable upon premisses or assumptions perfectly worthy of trust: while the alleged harmony is at best only a probable analogy, not certified by conclusive reasons.40 Kebês again, while admitting that the soul existed before its conjunction with the present body, and that it is sufficiently durable to last through conjunction with many different bodies — still expresses his apprehension that though durable, it is not eternal.

Accordingly, no man can be sure that his present body is not the last with which his soul is destined to be linked; so that immediately on his death, it will pass away into nothing. The opinion of Kebês is remarkable, inasmuch as it shows how constantly the metempsychosis, or transition of the soul from one body to another, was included in all the varieties of ancient speculation on this subject.41

Before replying to Simmias and Kebês, Sokrates is described as hesitating and reflecting for a long time. He then enters into a sketch of42 his own intellectual history. How far the sketch as it stands depicts the real Sokrates, or Plato himself, or a supposed mind not exactly coincident with either — we cannot be certain: the final stage however must belong to Plato himself.

“You compel me (says Sokrates) to discuss thoroughly the cause of generation and destruction.43 I will tell you, if you like, my own successive impressions on these subjects. When young, I was amazingly eager for that kind of knowledge which people call the investigation of Nature. I thought it matter of pride to know the causes of every thing — through what every thing is either generated, or destroyed, or continues to exist. I puzzled myself much to discover first of all such matters as these — Is it a certain putrefaction of the Hot and the Cold in the system (as some say), which brings about the nourishment of animals? Is it the blood through which we think — or air, or fire? Or is it neither one nor the other, but the brain, which affords to us sensations of sight, hearing, and smell, out of which memory and opinion are generated: then, by a like process, knowledge is generated out of opinion and memory when permanently fixed?44 I tried to understand destructions as well as generations, celestial as well as terrestrial phenomena. But I accomplished nothing, and ended by fancying myself utterly unfit for the enquiry. Nay — I even lost all the knowledge of that which I had before believed myself to understand. For example — From what cause does a man grow? At first, I had looked upon this as evident — that it was through eating and drinking: flesh being thereby added to his flesh, bone to his bone, &c.

So too, when a tall and a short man were standing together, it appeared to me that the former was taller than the latter by the head — that ten were more than eight because two were added to them45 — that a rod of two cubits was greater than a rod of one cubit, because it projected beyond it by a half. Now — I am satisfied that I do not know the cause of any of these matters. I cannot explain why, when one is added to one, such addition makes them two; since in their separated state each was one. In this case, it is approximation or conjunction which is said to make the two: in another case, the opposite cause, disjunction, is said also to make two — when one body is bisected.46 How two opposite causes can produce the same effect — and how either conjunction or disjunction can produce two, where there were not two before — I do not understand. In fact, I could not explain to myself, by this method of research, the generation, or destruction, or existence, of any thing; and I looked out for some other method.

“It was at this time that I heard a man reading out of a book, which he told me was the work of Anaxagoras, the affirmation that Nous (Reason, Intelligence) was the regulator and cause of all things. I felt great satisfaction in this cause; and I was convinced, that if such were the fact, Reason would ordain every thing for the best: so that if I wanted to find out the cause of any generation, or destruction, or existence, I had only to enquire in what manner it was best that such generation or destruction should take place. Thus a man was only required to know, both respecting himself and respecting other things, what was the best: which knowledge, however, implied that he must also know what was worse — the knowledge of the one and of the other going together.47 I thought I had thus found a master quite to my taste, who would tell me, first whether the earth was a disk or a sphere, and would proceed to explain the cause and the necessity why it must be so, by showing me how such arrangement was the best: next, if he said that the earth was in the centre, would proceed to show that it was best that the earth should be in the centre. Respecting the Sun, Moon, and Stars, I expected to hear the like explanation of their movements, rotations, and other phenomena: that is, how it was better that each should do and suffer exactly what the facts show. I never imagined that Anaxagoras, while affirming that they were regulated by Reason, would put upon them any other cause than this — that it was best for them to be exactly as they are.

I presumed that, when giving account of the cause, both of each severally and all collectively, he would do it by setting forth what was best for each severally and for all in common. Such was my hope, and I would not have sold it for a large price.48 I took up eagerly the book of Anaxagoras, and read it as quickly as I could, that I might at once come to the knowledge of the better and worse.

“Great indeed was my disappointment when, as I proceeded with the perusal, I discovered that the author never employed Reason at all, nor assigned any causes calculated to regulate things generally: that the causes which he indicated were, air, æther, water, and many other strange agencies. The case seemed to me the same as if any one, while announcing that Sokrates acts in all circumstances by reason, should next attempt to assign the causes of each of my proceedings severally:49 As if he affirmed, for example, that the cause why I am now sitting here is, that my body is composed of bones and ligaments — that my bones are hard, and are held apart by commissures, and my ligaments such as to contract and relax, clothing the bones along with the flesh and the skin which keeps them together — that when the bones are lifted up at their points of junction, the contraction and relaxation of the ligaments makes me able to bend my limbs — and that this is the reason why I am now seated here in my present crumpled attitude: or again — as if, concerning the fact of my present conversation with you, he were to point to other causes of a like character — varieties of speech, air, and hearing, with numerous other similar facts — omitting all the while to notice the true causes, viz.50 — That inasmuch as the Athenians have deemed it best to condemn me, for that reason I too have deemed it best and most righteous to remain sitting here and to undergo the sentence which they impose.

For, by the Dog, these bones and ligaments would have been long ago carried away to Thebes or Megara, by my judgment of what is best — if I had not deemed it more righteous and honourable to stay and affront my imposed sentence, rather than to run away. It is altogether absurd to call such agencies by the name of causes. Certainly, if a man affirms that unless I possessed such joints and ligaments and other members as now belong to me, I should not be able to execute what I have determined on, he will state no more than the truth. But to say that these are the causes why I, a rational agent, do what I am now doing, instead of saying that I do it from my choice of what is best — this would be great carelessness of speech: implying that a man cannot see the distinction between that which is the cause in reality, and that without which the cause can never be a cause.51 It is this last which most men, groping as it were in the dark, call by a wrong name, as if it were itself the cause. Thus one man affirms that the earth is kept stationary in its place by the rotation of the heaven around it: another contends that the air underneath supports the earth, like a pedestal sustaining a broad kneading-trough: but none of them ever look out for a force such as this — That all these things now occupy that position which it is best that they should occupy.

These enquirers set no great value upon this last-mentioned force, believing that they can find some other Atlas stronger, more everlasting, and more capable of holding all things together: they think that the Good and the Becoming have no power of binding or holding together any thing.

“Now, it is this sort of cause which I would gladly put myself under any one’s teaching to learn. But I could neither find any teacher, nor make any way by myself. Having failed in this quarter, I took the second best course, and struck into a new path in search of causes.52 Fatigued with studying objects through my eyes and perceptions of sense, I looked out for images or reflections of them, and turned my attention to words or discourses.53 This comparison is indeed not altogether suitable: for I do not admit that he who investigates things through general words, has recourse to images, more than he who investigates sensible facts: but such, at all events, was the turn which my mind took. Laying down such general assumption or hypothesis as I considered to be the strongest, I accepted as truth whatever squared with it, respecting cause as well as all other matters. In this way I came upon the investigation of another sort of cause.54
