This gave me occasion to observe, that when Men are employ'd they are best contented. For on the Days they work'd they were good-natur'd and chearful; and with the consciousness of having done a good Days work they spent the Evenings jollily; but on the idle Days they were mutinous and quarrelsome, finding fault with their Pork, the Bread, and in continual ill-humour. (Autobiography, 1771)

The worst wheel of the cart makes the most noise.

People willing to trade their freedom for temporary security deserve neither and will lose both.

Hot things, sharp things, sweet things, cold things All rot the teeth, and make them look like old things.

If you, do what you should not, you must bear what you would not.
