Charles R. Magel, Professor and Animal rights activist. - "Ask the experimenters why they experiment on animals, and the answer is: 'Because the animals are like us.' Ask the experimenters why it is morally okay to experiment on animals, and the answer is: 'Because the animals are not like us.' Animal experimentation rests on a logical contradiction."
