Never been said better than this: I think this is so appropriate, particluarly in regards to the last two weeks developments. As we try to figure out which way the culture is sliding on any given day, it's nice to be reminded of the ideal.

The sole end for which mankind are warranted, individually of collectively, in interfering with the liberty or action of any of their number is self-protection...The only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant...The only part of the conduct of any one, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign.

John Stuart Mill On Liberty
