"Although I have been prevented by outward circumstances from observing a strictly vegetarian diet, I have long been an adherent to the cause in principle. Besides agreeing with the aims of vegetarianism for aesthetic and moral reasons,it is my view that a vegetarian manner of living by its purely physical effect on the human temperament would most beneficially influence the lot of mankind."
Translation of letter to Hermann Huth, December 27, 1930. Einstein Archive 46-756
"If a man aspires towards a righteous life, his first act of abstinence is from injury to animals."
