Alexis de Tocqueville

They [socialists] unceasingly attempt to mutilate, to curtail, to obstruct personal freedom in any and all ways. They hold that the State must not only act as the director of society, but must further be master of each man, and not only master, but keeper and trainer. For fear of allowing him to err, the State must place itself forever by his side, above him, around him, better to guide him, to maintain him, in a word, to confine him. They call, in fact, for the forfeiture, to a greater or less degree, of human liberty, to the point where, were I to attempt to sum up what socialism is, I would say that it was simply a new system of serfdom.

Alexis de Tocqueville, September 12, 1848, a speech in front of the Constituent Assembly.
