WHEREVER I lecture, as a rule, some ministers think it their duty to reply for the purpose of showing either that I am unfair, or that I am blasphemous, or that I laugh. And laughing has always been considered by theologians as a crime. Ministers have always said you will have no respect for our ideas unless you are solemn. Solemnity is a condition precedent to believing anything without evidence. And if you can only get a man solemn enough, awed enough, he will believe anything. In this city the Rev. Dr. Thomas has made a few remarks, and I may say by way of preface that I have always held him in the highest esteem. He struggles, according to his statement, with the problem of my sincerity, and he about half concludes that I am not sincere. There is a little of the minister left in Dr. Thomas. Ministers always account for a difference of opinion by attacking the motive. Now, to him, it makes no difference whether I am sincere or insincere; the question is, Can my argument be answered? Suppose you could prove that the maker of the multiplication table held mathematics in contempt; what of it? Ten times ten would be a hundred still. My sincerity has nothing to do with the force of the argument--not the slightest. But this gentleman begins to suspect that I am doing what I do for the sake of applause. What a commentary on the Christian religion, that, after they have been preaching it for sixteen or eighteen hundred years, a man attacks it for the sake of popularity--a man attacks it for the purpose of winning applause! When I commenced to speak upon this subject there was no appreciable applause; most of my fellow-citizens differed with me; and I was denounced as though I had been a wild beast. But I have lived to see the majority of the men and women of intellect in the United States on my side; I have lived to see the church deny her creed; I have lived to see ministers apologize in public for what they preached; and a great and glorious work is going on until, in a little while, you will not find one of them, unless it is some old petrifaction of the red-stone period, who will admit that he ever believed in the Trinity, in the Atonement, or in the doctrine of Eternal Agony. The religion preached in the pulpits does not satisfy the intellect of America, and if Dr. Thomas wishes to know why people go to hear infidelity it is this: Because they are not satisfied with the orthodox Christianity of the day. That is the reason. They are beginning to hold it in contempt.
