Nature and society are so replete with startling contrasts that wit often consists in the mere statement and comparison of facts, as when Hume says that the ancient Muscovites wedded their wives with a whip instead of a ring.

The essence of the ludicrous consists in surprise,--in unexpected terms of feeling and explosions of thought,--often bringing dissimilar things together with a shock; as when some wit called Boyle, the celebrated philosopher, the father of chemistry and brother of the Earl of Cork.

Nature does not capriciously scatter her secrets as golden gifts to lazy pets and luxurious darlings, but imposes tasks when she presents opportunities, and uplifts him whom she would inform. The apple that she drops at the feet of Newton is but a coy invitation to follow her to the stars.

Some men find happiness in gluttony and in drunkenness, but no delicate viands can touch their taste with the thrill of pleasure, and what generosity there is in wine steadily refuses to impart its glow to their shriveled hearts.

A composition which dazzles at first sight by gaudy epithets, or brilliant turns or expression, or glittering trains of imagery, may fade gradually from the mind, leaving no enduring impression; but words which flow fresh and warm from a full heart, and which are instinct with the life and breath of human feeling, pass into household memories, and partake of the immortality of the affections from which they spring.

Men educate each other in reason by contact or collision, and keep each other sane by the very conflict of their separate hobbies. Society as a whole is the deadly enemy of the particular crotchet of each, and solitude is almost the only condition in which the acorn of conceit can grow to the oak of perfect self-delusion.

The strife of politics tends to unsettle the calmest understanding, and ulcerate the most benevolent heart. There are no bigotries or absurdities too gross for parties to create or adopt under the stimulus of political passions.
