I have long held the opinion that the amount of noise that anyone can bear undisturbed stands in inverse proportion to his mental capacity and therefore be regarded as a pretty fair measure of it.
As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.
For it is a matter of daily observation that people take the greatest pleasure in that which satisfies their vanity; and vanity cannot be satisfied without comparison with others.

A man who has no mental needs, because his intellect is of the narrow and normal amount, is, in the strict sense of the word, what is called a philistine.
We must set limits to our wishes, curb our desires, moderate our anger, always remembering that an individual can attain only an infinitesimal share in anything that is worth having; and that on the other hand, everyone must incur many of the ills of life
If the world were a paradise of luxury and ease, a land flowing with milk and honey, where every Jack obtained his Jill at once and without any difficulty, men would either die of boredom or hang themselves; or there would be wars, massacres, and murders; so that in the end mankind would inflict more suffering on itself than it has now to accept at the hands of Nature.
The vanity of existence is revealed in the whole form existence assumes: in the infiniteness of time and space contrasted with the finiteness of the individual in both; in the fleeting present as the sole form in which actuality exists; in the contingency and relativity of all things; in continual becoming without being; in continual desire without satisfaction; in the continual frustration of striving of which life consists. . . Time is that by virtue of which everything becomes nothingness in our hands and loses all real value.
