Vivisection, viv'i-sek'shan, n. [< L. vivus, alive, and sectio, sectionis, a cutting.]
The dissection of, or otherwise experimenting on, a living animal, esp. for the purpose of ascertaining or demonstrating some
fact in physiology or pathology. -Websters Dictionary
"Practically all animal experiments are untenable on a statistical scientific basis, for they possess no scientific validity or reliability. They merely perform an alibi function for pharmaceutical companies, who hope to protect themselves thereby."
From Tierversuch und Tierexperimentator (Vivisection and Vivisector) by Herbert Stiller, M.D. and Margot Stiller, M.D., Hanover, 1976
"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 upon unconsenting animals is the basis of my enmity towards it, and it is to me sufficient justification of the enmity without looking further. It is so distinctly a matter of feeling with me, and is so strong and so deeply-rooted in my make and constitution, that I am sure I could not even see a vivisector vivisected with anything more than a sort of qualified satisfaction. I do not say I should not go and look on; I only mean that I should almost surely fail to get out of it the degree of contentment which it ought, of course, to be expected to furnish."
Mark Twain (1835-1910), author, lecturer, satirist and humorist, Letter to London Anti-Vivisection Society, May 26, 1899
