I read these words which are the sum of all moral philosophy, and which cut short all the disputes of the casuists: When in doubt if an action is good or bad, refrain.

If you have two religions in your land, the two will cut each other’s throats; but if you have thirty religions, they will dwell in peace

What can you say to a man who tells you he prefers obeying God rather than men, and that as a result he's certain he'll go to heaven if he cuts your throat?

If there were only one religion in England there would be danger of despotism, if there were two, they would cut each other's throats, but there are thirty, and they live in peace and happiness.
