I'm no expert in philosophy, but I do know that many renowned ancient philosophers like Socrates and Aristotle owned slaves. When did philosophers start talking about human rights, like right to self-ownership, right to dignity, or even right to free expression? Is there a single philosopher or school of philosophy credited for "inventing" human rights?
I know there are some ancient documents supporting the idea of human rights, like the Code of Hammurabi, but I'm more interested in the philosophical aspect of it all. Like, when was the first time someone said "hey, maybe it's not morally right to own people as slaves"?
The first mention that I know of comes from 1499, from Gonzalo García de Santa María, Spanish writer, in his Chronicle of Aragon. I translate:
And I say, "why were they not put to work?". I tell you that not for a lack of strength and disposition, but for being measurate, and just, that they never liked stealing what was not theirs, or to force anyone. They never wanted to use their strength to take profit from others, inflicting damage, breaking human rights, the rule of reason, and Nature's law that compels humanity to recognise eachother as brothers.
García de Santa María, Gonzalo, Chronicle of Aragon, 1499, fol 10r.
At least in Spain, that is the first time we see the concept of "human rights".
