The only safe and honorable course for a self-respecting man is to do what I have decided to do, that is, to submit without protest to the penalty of disobedience ... not for want of respect for lawful authority, but in obedience to the higher law of our being, the voice of conscience.
Animal experimentation is the blackest of all the black crimes that a man is at present committing... We should be able to refuse to live if the price of living be the torture of sentient beings... I abhor [animal] experimentation with my whole soul. All the scientific discoveries stained with innocent blood I count as of no consequence... The greatness of a nation and its moral progress can be judged by the way its animals are treated.
