The right of revolution is an inherent one. When people are oppressed by their government, it is a natural right they enjoy to relieve themselves of the oppression, if they are strong enough, whether by withdrawal from it, or by overthrowing it and substituting a government more acceptable.
~ in Personal Memoirs, vol. 1
I never learned to swear. When a boy I seemed to have an aversion to it, and when I became a man I saw th folly of it. I have always noticed, too, that swearing helps to rouse a man’s anger; and when a man flies into a passion his adversary who keeps cool always gets the better of him. In fact, i could never see the use of swearing. I think it is the case with many people who swear excessively that they do not mean to be profane; but, to say the least, it is a great waste of time.
