Whenever I hear the quote 'I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops' I think about women. All the women from the beginning of time who have spent their lives cleaning up after men, serving men their meals, raising men's children, while the men around them, their brothers and sons, by the accident of being born a man, have enjoyed relative freedom and autonomy. Enslaving half of the population isn't just a tragedy for those enslaved...it is a tragedy for society in general when you're not tapping into the brain power of half of the human population for almost the entirety of human history.
