He who, when called upon to speak a disagreeable truth, tells it boldly and has done is both bolder and milder than he who nibbles in a low voice and never ceases nibbling.

He who is passionate and hasty is generally honest. It is your cool, dissembling hypocrite of whom you should beware.

A sneer is often the sign of heartless malignity.

Copiousness and simplicity, variety and unity, constitute real greatness of character.

Each particle of matter is an immensity, each leaf a world, each insect an inexplicable compendium.

The proportion of genius to the vulgar is like one to a million.

All finery is a sign of littleness.
