Truth is a fruit that can only be picked when it is very ripe.

Doubt is not a pleasant condition, but certainty is absurd.

Chance is a word void of sense; nothing can exist without a cause.

Pleasure has its time; so too, has wisdom. Make love in thy youth, and in old age attend to thy salvation.

Stand upright, speak thy thoughts, declare The truth thou hast, that all may share; Be bold, proclaim it everywhere: They only live who dare.

Quand celui à qui l'on parle ne comprend pas et celui qui parle ne se comprend pas, c'est de la métaphysique When he to whom a person speaks does not understand, and he who speaks does not understand himself, that is metaphysics.

Reading nurtures the soul, and an enlightened friend brings it solace.
