Now I have spoken and advised you enough on these studies for the present. It remains to tell you about “wisdom” and “philosophy.”See General Introd. pp. xxvi ff. It is true that if one were pleading a case on any other issue it would be out of place to discuss these words (for they are foreign to all litigation), but it is appropriate for me, since I am being tried on such an issue, and since I hold that what some people call philosophy is not entitled to that name, to define and explain to you what philosophy, properly conceived, really is.

My view of this question is, as it happens, very simple. For since it is not in the nature of man to attain a science by the possession of which we can know positively what we should do or what we should say, in the next resort I hold that man to be wise who is able by his powers of conjecture to arrive generally at the best course, and I hold that man to be a philosopher who occupies himself with the studies from which he will most quickly gain that kind of insight.See Isoc. 15.184 and note.

What the studies are which have this power I can tell you, although I hesitate to do so; they are so contrary to popular belief and so very far removed from the opinions of the rest of the world, that I am afraid lest when you first hear them you will fill the whole court-room with your murmurs and your cries. Nevertheless, in spite of my misgivings, I shall attempt to tell you about them; for I blush at the thought that anyone might suspect me of betraying the truth to save my old age and the little of life remaining to me.Cf. Plat. Apol. 38c.
