Know that thou art not fit to be thine own counsellor, and therefore shouldst fear and be diffident of thine own opinions as proceeding from a source that is marred and corrupt. Under this conviction thou wilt, as far as it is possible, always take counsel of some wise and conscientious person, and prefer rather to be led by one better than thyself than to follow thine own devices.
-Pope Leo XIII, Vaughan.
