Nothing that goes on in anyone else's mind can harm you.

Hast thou reason? I have. Why then dost not thou use it? For if this does its own work, what else dost thou wish?

Anything that is beautiful is beautiful just as it is. Praise forms no part of its beauty, since praise makes things neither better nor worse. This applies even more to what it commonly called beautiful: natural objects, for example, or works of art. True beauty has no need of anything beyond itself.

Search men's governing principles, and consider the wise, what they shun and what they cleave to.

Cultivate these, then, for they are wholly within your power: sincerity and dignity; industriousness; and sobriety. Avoid grumbling, be frugal, considerate, and frank; be temperate in manner and speech; carry yourself with authority.

Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.

If any man despises me, that is his problem. My only concern is not doing or saying anything deserving of contempt.
