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

I believe I am not interested to know whether vivisection produces results that are profitable to the human race or doesn’t. To know that the results are profitable to the race would not remove my hostility to it. The pains which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of enmity without looking further.

Perhaps the greatest social service that can be rendered by anybody to the country and to mankind is to bring up a family.

The lack of money is the root of all evil.

What we want is to see the child in pursuit of knowledge, and not knowledge in pursuit of the child.
