Mark Twain Biography

American writer and humorist
Con to the question "Should Animals Be Used for Scientific or Commercial Testing?"

“I believe I am not interested to know whether Vivisection produces results that are profitable to the human race or doesn’t. To know that the results are profitable to the race would not remove my hostility to it. The pains which it inflicts on unconsenting animals is the basis of my enmity toward it, & is to me sufficient justification of the enmity without looking further.”

Letter to the London Anti-Vivisection Society dated May 26, 1899, Mark Twain’s Book of Animals, 2010
