Never does nature say one thing and wisdom another.

The wisdom of the wise is an uncommon degree of common sense.

Virtues are acquired through endeavor, which rests wholly upon yourself.

You must learn day by day, year by year to broaden your horizon. The more things you love, the more you are interested in, the more you enjoy, the more you are indignant about, the more you have left when anything happens.

Man's wisdom is his best friend folly his worst enemy.
