Quotes

"If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence."
- Bertrand Russell

  3. Can consent override rights? by Laughable Junnyzup in Ethics
