The safest thing is always to try to convert everything that is in us and around us into action; let the others talk and argue about it as they please.

Children, love one another, and if that is not possible-at least try to put up with one another.

Truth is a torch, but a terrific one; therefore we all try to reach it with closed eyes, lest we should be scorched.

There is nothing worth thinking but it has been thought before; we must only try to think it again.
