When intuition and logic agree, you are always right.

Let a man choose what condition he will, and let him accumulate around him all the goods and gratifications seemingly calculated to make him happy in it; if that man is left at any time without occupation or amusement, and reflects on what he is, the meagre, languid felicity of his present lot will not bear him up. He will turn necessarily to gloomy anticipations of the future; and unless his occupation calls him out of himself, he is inevitably wretched.

By space the universe encompasses and swallows me up like an atom; by thought I comprehend the world.

Kind words do not cost much. They never blister the tongue or lips. They make other people good-natured. They also produce their own image on men's souls, and a beautiful image it is.

Our nature consists in motion; complete rest is death.

Apart from Jesus Christ, we do not know what is our life, nor our death, nor God, nor ourselves.

Earnestness is enthusiasm tempered by reason.
