"Remember that animals are born to live their own lives, not to serve you! Do not use them; do not exploit them. Let them live their own lives."

To be born, to live and to die is merely to change forms... And what does one form matter any more than another?... Each form has its own sort of happiness and unhappiness. From the elephant down to the flea... from the flea down to the sensitive and living molecule which is the origin of all, there is not a speck in the whole of nature that does not feel pain or pleasure.

— John Dewey
