The truth is, of course, that the curtness of the Ten Commandments is an evidence, not of the gloom and narrowness of a religion, but, on the contrary, of its liberality and humanity. It is shorter to state the things forbidden than the things permitted: precisely because most things are permitted, and only a few things are forbidden.
G. K. Chesterton

To have a right to do a thing is not at all the same as to be right in doing it.
G. K. Chesterton, A Short History of England, Ch.10
