America doesn't know today how proud she ought to be of her Ingersoll.

Shocked? I consider Bob one of the constellations of our time — of our country — America — a bright, magnificent constellation. Besides, all the constellations—not alone of this but of any time—shock the average intelligence for a while. In one respect that helps to prove it a constellation. Think of Voltaire, Paine, Hicks, not to say anything of modern men whom we could mention.

{Whitman's thoughts on his close friend, the great Robert Ingersoll}

Paine was a grand fellow — high—with the most splendid sense of justice. But he was a reasoner — not warm — not letting out the natural palpitating passion... which perhaps he didn't have. But I see all that and more in Ingersoll. His imagination flames and plays up, up, up. It is a grand height! And he has so sharp a blade, too; is many-sided, gifted for great effects in different spheres. I don't suppose we ever had a man here so well adapted to that work.

{Whitman's thought on Thomas Paine and his good friend, Robert Ingersoll}

Ingersoll is with Homer and Tully and Shakespeare and Burns.

He is a type of our best — our rarest. Electrical, I was going to say, beyond anyone, perhaps, ever was: charged, surcharged. Not a founder of new philosophies — not of that build. But a towering magnetic presence, filling the air about with light, warmth, inspiration. A great intellect, penetrating, in ways (on his field) the best of our time — to be long kept, cherished, passed on... It should not be surprising that I am drawn to Ingersoll, for he is 'Leaves of Grass.' He lives, embodies, the individuality I preach. 'Leaves of Grass' utters individuality, the most extreme, uncompromising. I see in Bob the noblest specimen —American-flavored—pure out of the soil, spreading, giving, demanding light.

{Whitman's thought on his good friend, the great Robert Ingersoll}

He had all the attributes of a perfect man, and, in my opinion, no finer personality ever existed.
