"H[er] own good, either physical or moral, is not a sufficient warrant. [Sh]e cannot rightfully be compelled to do or forbear because it will be better for h[er] to do so, because it will make h[er] happier, because, in the opinions of others, to do so would be wise or even right. [...] The only part of the conduct of anyone for which [s]he is amenable to society is that which concerns others. In the part which merely concerns h[er]self, h[er] independence is, of right, absolute. Over h[er]self, over h[er] own body and mind, the individual is sovereign." -- John Stuart Mill, On Liberty
