Famous Richard D. Ryder Quote
The cruel experimenter cannot be allowed to have it both ways. He cannot, in the same breath, defend the scientific validity of vivisection on the grounds of the physical similarities between man and the other animals, and then defend the morality of vivisection on the grounds that men and animals are physically different. The only logical alternatives for him are to admit he is either pre-Darwinian or immoral.
