Men need some kind of external activity, because they are inactive within. - Arthur Schopenhauer

Pride is an established conviction of one’s own paramount worth in some particular respect, while vanity is the desire of rousing such a conviction in others, and it is generally accompanied by the secret hope of ultimately coming to the same conviction oneself. Pride works from within; it is the direct appreciation of oneself. Vanity is the desire to arrive at this appreciation indirectly, from without.

When you find human society disagreeable and feel yourself justified in flying to solitude, you can be so constituted as to be unable to bear the depression of it for any length of time, which will probably be the case if you are young. Let me advise you, then, to form the habit of taking some of your solitude with you into society, to learn to be to some extent alone even though you are in company; not to say at once what you think, and, on the other hand, not to attach too precise a meaning to what others say; rather, not to expect much of them, either morally or intellectually, and to strengthen yourself in the feeling of indifference to their opinion, which is the surest way of always practicing a praiseworthy toleration. If you do that, you will not live so much with other people, though you may appear to move amongst them: your relation to them will be of a purely objective character. This precaution will keep you from too close contact with society, and therefore secure you against being contaminated or even outraged by it. Society is in this respect like a fire — the wise man warming himself at a proper distance from it; not coming too close, like the fool, who, on getting scorched, runs away and shivers in solitude, loud in his complaint that the fire burns.

The intellectual attainments of a man who thinks for himself resemble a fine painting, where the light and shade are correct, the tone sustained, the colour perfectly harmonised; it is true to life. On the other hand, the intellectual attainments of the mere man of learning are like a large palette, full of all sorts of colours, which at most are systematically arranged, but devoid of harmony, connection and meaning.
