Choose always the way that seems the best, however rough it may be; custom will soon render it easy and agreeable

Rest satisfied with doing well, and leave others to talk of you as they will

Take the course opposite to custom and you will almost always do well

Wisdom thoroughly learned will never be forgotten

The custom and fashion of today will be the awkwardness and outrage of tomorrow - so arbitrary are these transient laws

As long as man continues to be the ruthless destroyer of lower living beings he will never know health or peace. For as long as men massacre animals, they will kill each other.
