The Works of Robert G. Ingersoll, Vol. 07 (of 12) / Dresden Edition—Discussions

This lecture was delivered by Col. Ingersoll in San Francisco Cal., June 27, 1877. It was a reply to various clergymen of that city, who had made violent attacks upon him after the delivery of his lectures, The Liberty of Man, Woman and Child, and The Ghosts.
AGAINST the aspersions of the pulpit and the religious press, I offer in evidence this magnificent audience. Although I represent but a small part of the holy cause of intellectual liberty, even that part shall not be defiled or smirched by a single personality. Whatever I say, I shall say because I believe it will tend to make this world grander, man nearer just, the father kinder, the mother more loving, the children more affectionate, and because I believe it will make an additional flower bloom in the pathway of every one who hears me.
In the first place, what have I said? What has been my offence? What have I done? I am spoken of by the clergy as though I were a wolf that in the absence of the good shepherd had fattened upon his innocent flock. What have I said?
I delivered a lecture entitled, The Liberty of Man, Woman and Child. In that lecture I said that man was entitled to physical and intellectual liberty. I defined physical liberty to be the right to do right; the right to do anything that did not interfere with the real happiness of others. I defined intellectual liberty to be the right to think right, and the right to think wrong—provided you did your best to think right.
This must be so, because thought is only an instrumentality by which we seek to ascertain the truth. Every man has the right to think, whether his thought is in reality right or wrong; and he cannot be accountable to any being for thinking wrong. There is upon man, so far as thought is concerned, the obligation to think the best he can, and to honestly express his best thought. Whenever he finds what is right, or what he honestly believes to be the right, he is less than a man if he fears to express his conviction before an assembled world.
