„I cannot kill. Unfortunately, there are so many who can and do kill. As I cannot kill I cannot authorize others to kill. Do you see? If you are buying from a butcher you are authorizing him to kill — kill helpless, dumb creatures, which neither I nor you could kill ourselves. So that I am for that reason a vegetarian, as most Russians are. For nine years I have been a vegetarian, and I shall be one — mind, I am a man with strong convictions — to the end of my life.“
— Paolo Troubetzkoy
