Mai 2011Berlin 2011D83”Cruelty to animals is one of the most significant vices of a low and ignoble people.Wherever one notices them, they constitute a sure sign of ignorance and brutalitywhich cannot be painted over even by all the evidence of wealth and luxury. Crueltyto animals cannot exist together with true education and true learning.”– Alexander von Humboldt†”I am not interested to know whether vivisection produces results that are profitableto the human race. The pain which it inflicts upon unconsenting animals is the basisof my enmity toward it, and it is to me sufficient justification of the enmity withoutlooking further”.– Mark Twain†”Imagine living your life in a small, filthy cage constantly in pain, unable to standor lie down comfortably. After months of agony, your torture finally ends, but notat the slaughterhouse.
