Michel de Montaigne

A wise man sees as much as he ought, not as much as he can.

Rejoice in the things that are present; all else is beyond thee.

He who establishes his argument by noise and command shows that his reason is weak.

Political differences will always generate a healthy debate, but over time the dialogue has become more hateful and at times violent.

But with each passing year and each new study, the evidence for the genetic contribution to individual and group differences becomes more firmly established than ever.

A doubtful friend is worse than a certain enemy. Let a man be one thing or the other, and we then know how to meet him.
