Men rise from one ambition to another: first, they seek to secure themselves against attack, and then they attack others.

Great ambition, the desire of real superiority, of leading and directing, seems to be altogether peculiar to man, and speech is the great instrument of ambition.

It's stasis that kills you off in the end, not ambition.

Ambition never is in a greater hurry than I; it merely keeps pace with circumstances and with my general way of thinking.
