Phaedo.To begin with, then, it is clear that in such matters the philosopher, more than other men, separates the soul from communion with the body?It is.Now certainly most people think that a man who takes no pleasure and has no part in such things doesn’t deserve to live, and that one who cares nothing for the pleasures of the body is about as good as dead.That is very true.Now, how about the acquirement of pure knowledge? Is the body a hindrance or not, if it is made to share in the search for wisdom? What I mean is this: Have the sight and hearing of men any truth in them, or is it true, as the poets are always telling us, that we neither hear nor see any thing accurately? And yet if these two physical senses are not accurate or exact, the rest are not likely to be, for they are inferior to these. Do you not think so?Certainly I do, he replied.Then, said he, when does the soul attain to truth? For when it tries to consider anything in company with the body, it is evidently deceived by it. True.In thought, then, if at all, something of the realities becomes clear to it? Yes. But it thinks best when none of these things troubles it, neither hearing nor sight, nor pain nor any pleasure, but it is, so far as possible, alone by itself, and takes leave of the body, and avoiding, so far as it can, all association or contact with the body, reaches out toward the reality.That is true.In this matter also, then, the soul of the philosopher greatly despises the body and avoids it and strives to be alone by itself?Evidently. Now how about such things as this, Simmias? Do we think there is such a thing as absolute justice, or not?We certainly think there is.And absolute beauty and goodness.Of course.Well, did you ever see anything of that kind with your eyes?Certainly not, said he.Or did you ever reach them with any of the bodily senses? I am speaking of all such things, as size, health, strength, and in short the essence or underlying quality of everything. Is their true nature contemplated by means of the body? Is it not rather the case that he who prepares himself most carefully to understand the true essence of each thing that he examines would come nearest to the knowledge of it?Certainly.

Phaedo.Would not that man do this most perfectly who approaches each thing, so far as possible, with the reason alone, not introducing sight into his reasoning nor dragging in any of the other senses along with his thinking, but who employs pure, absolute reason in his attempt to search out the pure, absolute essence of things, and who removes himself, so far as possible, from eyes and ears, and, in a word, from his whole body, because he feels that its companionship disturbs the soul and hinders it from attaining truth and wisdom? Is not this the man, Simmias, if anyone, to attain to the knowledge of reality?That is true as true can be, Socrates, said Simmias. Then, said he, all this must cause good lovers of wisdom to think and say one to the other something like this: There seems to be a short cut which leads us and our argument to the conclusion in our search that so long as we have the body, and the soul is contaminated by such an evil, we shall never attain completely what we desire, that is, the truth. For the body keeps us constantly busy by reason of its need of sustenance; and moreover, if diseases come upon it they hinder our pursuit of the truth. And the body fills us with passions and desires and fears, and all sorts of fancies and foolishness, so that, as they say, it really and truly makes it impossible for us to think at all. The body and its desires are the only cause of wars and factions and battles; for all wars arise for the sake of gaining money, and we are compelled to gain money for the sake of the body. We are slaves to its service. And so, because of all these things, we have no leisure for philosophy. But the worst of all is that if we do get a bit of leisure and turn to philosophy, the body is constantly breaking in upon our studies and disturbing us with noise and confusion, so that it prevents our beholding the truth, and in fact we perceive that, if we are ever to know anything absolutely, we must be free from the body and must behold the actual realities with the eye of the soul alone. And then, as our argument shows, when we are dead we are likely to possess the wisdom which we desire and claim to be enamored of, but not while we live.
