We must recognise that duty and morality vary under different circumstances; not that the man who resists evil is doing what is always and in itself wrong, but that in the different circumstances in which he is placed it may become even his duty to resist evil.
Anything which is a living and not a dying body... will have to be an incarnate will to power, it will strive to grow, spread, seize, become predominant - not from any morality or immorality but because it is living and because life simply is will to power... 'Exploitation'... belongs to the essence of what lives, as a basic organic function; it is a consequence of the will to power, which is after all the will to life.
There is too much tendency to attribute to God the evils that man does of his own free will. I must concede you the Devil. God doesn't really need to punish us, Miss Barton. We're so busy punishing ourselves.
Know thyself as the pride of His creation, the link uniting divinity and matter; behold a part of God Himself within thee; remember thine own dignity nor dare descend to evil or meanness.

Vivisection is a social evil because if it advances human knowledge, it does so at the expense of human character.
