The editor of a volume of Ingersoll's works writes about Ingersoll the following: "Colonel Robert G. Ingersoll occupies a unique position. He is to a large extent the productof his own generation. A man of the times, for the times. He has had no predecessor, he will have no successor.. Such a man was impossible a hundred years ago; the probabilities are that a century hence no such man will be needed. His work needs only to be done once."
McCabe writes about Ingersoll that "He was admittedly the foremost orator of the United States, and he is probably second to Voltaire in the record of enlightenment."
This work contains, among many other essays, poems, and sayings of Ingersoll, essays on Voltaire, Humboldt, August Compte, Napoleon, Thomas Paine, Bruno, Abraham Lincoln, Horace Seaver, Mrs. Mary H. Fiske, and Spinoza. It also includes tributes to Ebron C. Ingersoll (his brother), Rev. Alexander Clark, John G. Mills, Henry Ward Beecher, Courtlandt Palmer, Roscoe Conkling, Richard H. Whiting, and Walt Whitman.
This is the 6th edition of this work and it has been greatly enlarged, going from 248 pages to 405 pages.
