“The greatest deception men suffer is from their own opinions.”

“I have from an early age abjured the use of meat, and the time will come when men such as I will look upon the murder of animals as they now look upon the murder of men.”

“If you find from your own experience that something is a fact and it contradicts what some authority has written down, then you must abandon the authority and base your reasoning on your own findings.”

“The time will come when men such as I will look upon the murder of animals as they now look on the murder of men.”

“What is fair in men, passes away, but not so in art”

“Men of lofty genius when they are doing the least work are most active.”

“The worst evil which can befall the artist is that his work should appear good in his own eyes.”
