What does he desire who aspires after wisdom? He wishes to free himself from what the senses offer him in every-day perception. He seeks for the spirit in the sense-world. Is not this a fact which may be compared with dying? "For," according to Socrates, "those who occupy themselves with philosophy in the right way are really striving after nothing else than to die and to be dead, without this being perceived by others. If this is true, it would be strange if, after having aimed at this all through life, when death itself comes they should be indignant at that which they have so long striven after and taken pains about." To corroborate this, Socrates asks one of his friends: "Does it seem to you befitting a philosopher to take trouble about so-called fleshly pleasures, such as eating and drinking? or about sexual pleasures? And do you think that such a man pays much heed to other bodily needs? To have fine clothes, shoes, and other bodily adornments,--do you think he considers or scorns this more than utmost necessity demands? Does it not seem to you that it should be such a man's whole preoccupation not to turn his thoughts to the body, but as much as possible away from it and towards the soul? Therefore this is the first mark of the philosopher, that he, more than all other men, relieves his soul of association with the body." On this subject Socrates has something more to say, _i.e._, that aspiration after wisdom has this much in common with dying, that it turns man away from the physical. But whither does he turn? Towards the spiritual. But can he desire the same from spirit as from the senses? Socrates thus expresses himself on this point: "But how is it with reasonable knowledge itself? Is the body a hindrance or not, if we take it as a companion in our search for knowledge? I mean, do sight and hearing procure man any truth? Or is what the poets sing meaningless, that we see and hear nothing clearly?... When does the soul catch sight of truth? For when it tries to examine something with the help of the body, it is manifestly deceived by the latter." Everything of which we are cognisant by means of our bodily senses appears and disappears. And it is this appearing and disappearing which is the cause of our being deceived. But when with our reasonable intelligence we look deeper into things, the eternal element in them is revealed to us. Thus the senses do not offer us the eternal in its true form. The moment we trust them implicitly they deceive us. They cease to deceive us if we confront them with our thinking insight and submit what they tell us to its examination.
