Too much company is worse than none. - James Burgh

Make your company a rarity, and people will value it. Men despise what they can easily have.

There is no occasion to trample upon the meanest reptile, nor to sneak to the greatest prince. Insolence and baseness are equally unmanly.

In disputes upon moral or scientific points, ever let your aim be to come at truth, not to conquer your opponent: so you never shall be at a loss in losing the argument, and gaining a new discovery.
