I value society for the abundance of ideas that it brings before us, like carriages in a frequented street; but I value solitude for sincerity and peace, and for the better understanding of the thoughts that are truly ours. Only in solitude do we learn our inmost nature and its needs. He who has lived for some great space of existence apart from the tumult of the world, has discovered the vanity of the things for which he has no natural aptitude or gift--their _relative_ vanity, I mean, their uselessness to himself, personally; and at the same time he has learned what is truly precious and good for him. Surely this is knowledge of inestimable value to a man: surely it is a great thing for any one in the bewildering confusion of distracting toils and pleasures to have found out the labor that he is most fit for and the pleasures that satisfy him best. Society so encourages us in affectations that it scarcely leaves us a chance of knowing our own minds; but in solitude this knowledge comes of itself, and delivers us from innumerable vanities. Montaigne tells us that at one time he bought books from ostentation, but that afterwards he bought only such books as he wanted for his private reading. In the first of these conditions of mind we may observe the influence of society; in the second the effect of solitude. The man of the world does not consult his own intellectual needs, but considers the eyes of his visitors; the solitary student takes his literature as a lonely traveller takes food when he is hungry, without reference to the ordered courses of public hospitality.
