23. It is this that makes such carelessness in a matter of supreme importance all the more worthy of blame. I say "supreme importance," because friendship is the one thing about the utility of which everybody with one accord is agreed. That is not the case in regard even to virtue itself; for many people speak slightingly of virtue as though it were mere puffing and self-glorification. Nor is it the case with riches. Many look down on riches, being content with a little and taking pleasure in poor fare and dress, And as to the political offices for which some have a burning desire--how many entertain such a contempt for them as to think nothing in the world more empty and trivial! And so on with the rest; things desirable in the eyes of some are regarded by very many as worthless. But of friendship all think alike to a man, whether those have devoted themselves to politics, or those who delight in science and philosophy, or those who follow a private way of life and care for nothing but their own business, or those lastly who have given themselves body and soul to sensuality--they all think, I say, that without friendship life is no life, if they want some part of it, at any rate, to be noble. For friendship, in one way or another, penetrates into the lives of us all, and suffers no career to be entirely free from its influence. Though a man be of so churlish and unsociable a nature as to loathe and shun the company of mankind, as we are told was the case with a certain Timon at Athens, yet even he cannot refrain from seeking some one in whose hearing he may disgorge the venom of his bitter temper. We should see this most clearly, if it were possible that some god should carry us away from these haunts of men, and place us somewhere in perfect solitude, and then should supply us in abundance with everything necessary to our nature, and yet take from us entirely the opportunity of looking upon a human being. Who could steel himself to endure such a life? Who would not lose in his loneliness the zest for all pleasures? And indeed this is the point of the observation of, I think, Archytas of Tarentum. I have it third hand; men who were my seniors told me that their seniors had told them. It was this: "If a man could ascend to heaven and get a clear view of the natural order of the universe, and the beauty of the heavenly bodies, that wonderful spectacle would give him small pleasure, though nothing could be conceived more delightful if he had but had some one to whom to tell what he had seen." So true it is that nature abhors isolation, and ever leans upon something as a stay and support; and this is found in its most pleasing form in our closest friend.
