There are three classes of men; the retrograde, the stationary and the progressive.

You may tell a man thou art a fiend, but not your nose wants blowing; to him alone who can bear a thing of that kind, you may tell all.

Let none turn over books, or roam the stars in quest of God, who sees him not in man.

He submits himself to be seen through a microscope, who suffers himself to be caught in a fit of passion.

He whom common, gross, or stale objects allure, and when obtained, content, is a vulgar being, incapable of greatness in thought or action.

He who sedulously attends, pointedly asks, calmly speaks, coolly answers and ceases when he has no more to say is in possession of some of the best requisites of man

He who always seeks more light the more he finds, and finds more the more he seeks, is one of the few happy mortals who take and give in every point of time. The tide and ebb of giving and receiving is the sum of human happiness, which he alone enjoys who always wishes to acquire new knowledge, and always finds it.
