The nature of human beings never changes; it is immutable. The present generation of children and the present generation of young adults from the age of thirteen to eighteen is, therefore, no different from that of their great-great-grandparents.

Men who retain irony are not to be trusted. They can't always resist an impulse to tickle themselves.

Honest men live on charity in their age; the almshouses are full of men who never stole a copper penny. Honest men are the fools and the saints.
