It is a great act of cleverness to be able to conceal one's being clever.

What seems to be generosity is often no more than disguised ambition, which overlooks a small interest in order to secure a great one.

However glorious an action in itself, it ought not to pass for great if it be not the effect of wisdom and intention.

They that apply themselves to trifling matters commonly become incapable of great ones.
