Leonardo da Vinci

Truly man is the king of beasts, for his brutality exceeds theirs. We live by the death of others: we are burial places! I have from an early age abjured the use of meat, and the time will come when men such as I will look on the murder of animals as they look now on the murder of men. 

~ Leonardo da Vinci
