“Of all the groups that sometimes claim to own your life, family is the hardest to defend your individual sovereignty from.”

Discourse on Voluntary Servitude (1548)
Context: Poor, wretched, and stupid peoples, nations determined on your own misfortune and blind to your own good! You let yourselves be deprived before your own eyes of the best part of your revenues; your fields are plundered, your homes robbed, your family heirlooms taken away. You live in such a way that you cannot claim a single thing as your own; and it would seem that you consider yourselves lucky to be loaned your property, your families, and your very lives. All this havoc, this misfortune, this ruin, descends upon you not from alien foes, but from the one enemy whom you yourselves render as powerful as he is, for whom you go bravely to war, for whose greatness you do not refuse to offer your own bodies unto death. He who thus domineers over you has only two eyes, only two hands, only one body, no more than is possessed by the least man among the infinite numbers dwelling in your cities; he has indeed nothing more than the power that you confer upon him to destroy you. Where has he acquired enough eyes to spy upon you, if you do not provide them yourselves? How can he have so many arms to beat you with, if he does not borrow them from you? The feet that trample down your cities, where does he get them if they are not your own? How does he have any power over you except through you? How would he dare assail you if he had no cooperation from you? What could he do to you if you yourselves did not connive with the thief who plunders you, if you were not accomplices of the murderer who kills you, if you were not traitors to yourselves? You sow your crops in order that he may ravage them, you install and furnish your homes to give him goods to pillage; you rear your daughters that he may gratify his lust; you bring up your children in order that he may confer upon them the greatest privilege he knows — to be led into his battles, to be delivered to butchery, to be made the servants of his greed and the instruments of his vengeance; you yield your bodies unto hard labor in order that he may indulge in his delights and wallow in his filthy pleasures; you weaken yourselves in order to make him the stronger and the mightier to hold you in check.

The Blank Slate (2002)

Context: [E]quality is not the empirical claim that all groups of humans are interchangeable; it is the moral principle that individuals should not be judged or constrained by the average properties of their group. … If we recognize this principle, no one has to spin myths about the indistinguishability of the sexes to justify equality.

Context: Looking back, I think he knew that in my innocence I was eager to love everything and please everybody, and he was trying to warn me not to lose my own identity in the process. Time after time he came back to this theme. " The individual has always had to struggle to keep from being overwhelmed by the tribe. To be your own man is a hard business. If you try it, you'll be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself."
