We are the product of 4.5 billion years of fortuitous, slow biological evolution. There is no reason to think that the evolutionary process has stopped. Man is a transitional animal. He is not the climax of creation.
Animals have these advantages over man: they never hear the clock strike, they die without any idea of death, they have no theologians to instruct them, their last moments are not disturbed by unwelcome and unpleasant ceremonies, their funerals cost them nothing, and no one starts lawsuits over their wills.
It is easy to find fault, if one has that disposition. There was once a man who, not being able to find any other fault with his coal, complained that there were too many prehistoric toads in it.
He hath not eat paper, as it were; he hath not drunk ink; his intellect is not replenished; he is only an animal, only sensible in the duller parts. (Shakespeare, Love's Labor's Lost, IV)

I am not interested to know whether vivisection produces results that are profitable to the human race or doesn't...The pain which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of the enmity without looking further.
Three quiet days. This hell fiend is like a cat with a mouse. She lets me loose only to pounce upon me again. I am never so frightened as when every thing is still.
He had been content with daily labour and rough animal enjoyments, 'till Catherine crossed his path.
