Pity is not natural to man. Children are always cruel. Savages are always cruel. Pity is acquired and improved by the cultivation of reason. We may have uneasy sensations from seeing a creature in distress, without pity; for we have not pity unless we wish to relieve them.

Merit rather enforces respect than attracts fondness.

Health is so necessary to all the duties, as well as pleasures of life, that the crime of squandering it is equal to the folly.

From ignorance our comfort flows, the only wretched are the wise

In most ages many countries have had part of their inhabitants in a state of slavery; yet it may be doubted whether slavery can ever be supposed the natural condition of man. It is impossible not to conceive that men in their original state were equal; and very difficult to imagine how one would be subjected to another but by violent compulsion. An individual may, indeed, forfeit his liberty by a crime; but he cannot by that crime forfeit the liberty of his children.

The prosperity of a people is proportionate to the number of hands and minds usefully employed. To the community, sedition is a fever, corruption is a gangrene, and idleness is an atrophy. Whatever body or society wastes more than it acquires, must gradually decay, and every being that continues to be fed, and eases to labor, takes away something from the public stock.

He who praises everybody, praises nobody.
