Mathematical proofs, like diamonds, are hard and clear, and will be touched with nothing but strict reasoning.

Now, I appeal to the consciences of those that persecute, torment, destroy, and kill other men upon pretence of religion, whether they do it out of friendship and kindness towards them or no?
