Pleasure is never as pleasant as we expected it to be and pain is always more painful. The pain in the world always outweighs the pleasure. If you don't believe it, compare the respective feelings of two animals, one of which is eating the other.

One should use common words to say uncommon things

Whether we are in a pleasant or a painful state depends, finally, upon the kind of matter that pervades and engrosses our consciousness and what we compare it to - better and we envious and sad, worse and we feel grateful and happy.

Everybody's friend is nobody's.

Human life must be some form of mistake.

Life is short and truth works far and lives long: let us speak the truth.

The best consolation in misfortune or affliction of any kind will be the thought of other people who are in a still worse plight than yourself; and this is a form of consolation open to every one. But what an awful fate this means for mankind as a whole! We are like lambs in a field, disporting themselves under the eye of the butcher, who chooses out first one and then another for his prey.
