The Past - the dark unfathomed retrospect! The teeming gulf -the sleepers and the shadows! The past! the infinite greatness of the past! For what is the present after all but a growth out of the past?

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}

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.
