"I am most deeply anxious to impress upon the minds and understandings of every true Irishman, that disloyalty to his sovereign would be double treason to his country; it would be perjury, aggravated by folly, and followed by the eternal extinction of the liberties of Ireland. And what prospect could there possibly be of aught besides destruction? ... For myself, I will tell you honestly, that if ever that fatal day arrive, you will find me arrayed against you. There will not be so heavy a heart; but there will not be a more ready hand to sustain the constitution against every enemy!"
