“Twice two is four is not life, gentlemen, but the beginning of death.”

“Twice two makes four seems to me simply a piece of insolence. Twice two makes four is a pert coxcomb who stands with arms akimbo barring your path and spitting.”

“Twice two makes four seems to me simply a piece of insolence. Twice two makes four is a pert coxcomb who stands with arms akimbo barring your path and spitting.

And although our life, in this manifestation of it, is often worthless, yet it is life and not simply extracting square roots.”
