Indeed in general I hold that there is nothing truer than happiness, and nothing happier and sweeter than truth.
Gottfried LeibnizTaking mathematics from the beginning of the world to the time when Newton lived, what he had done was much the better half.
Gottfried LeibnizLet there be two possible things, A and B, one of which is such that it is necessary that it exists, and let us assume that there is more perfection in A than in B. Then, at least, we can explain why A should exist rather than B and can foresee which of them will exist; indeed, this can be demonstrated, that is, rendered certain from the nature of the thing.
