After the primary necessities of food and raiment, freedom is the first and strongest want of human nature. - John Stuart Mill

Protection, therefore, against tyranny of the magistrate is not enough: there needs protection also against the tyranny of the prevailing opinion and feeling; against the tendency of society to impose, by other means than civil penalties, its own ideas and practices as rules of conduct on those who dissent from them; to fetter the development, and, if possible, prevent the formation, of any individuality not in harmony with its ways, and compel all characters to fashion themselves upon the model of its own.

There is always need of persons not only to discover new truths, and point out when what were once truths are true no longer, but also to commence new practices, and set the example of more enlightened conduct, and better taste and sense in human life.

The greater part of the world has, properly speaking, no history, because the despotism of Custom is complete. This is the case over the whole East. Custom is there, in all things, the final appeal; justice and right mean conformity to custom; the argument of custom no one, unless some tyrant intoxicated with power, thinks of resisting. And we see the result. Those nations must once have had originality; they did not start out of the ground populous, lettered, and versed in many of the arts of life; they made themselves all this, and were then the greatest and most powerful nations in the world. What are they now? The subjects or dependants of tribes whose forefathers wandered in the forests when theirs had magnificent palaces and gorgeous temples, but over whom custom exercised only a divided rule with liberty and progress.
