I’d never heard of this 19th-Century (born 1833) lecturer, lawyer, teacher, politician, and Union colonel (who served at Shiloh), until I read an article on him.
I claim that the Democratic party embraces within its filthy arms the worst elements in American society. I claim that every enemy that this Government has had for twenty years has been and is a Democrat . . . every State that has seceded from this Union was a Democratic State . . . The man that shot Lincoln was a Democrat. And every man that was glad of it was a Democrat.
— Robert Ingersoll, 1876
.
I admit that the Republican party is not altogether good. [Laughter.] I admit, and you will wonder at my candor, that the Democratic party is not altogether bad. [Renewed laughter.] I admit that the Democratic party in its great and splendid effort to do wrong has sometimes by mistake done right. [Laughter and applause.]
— Speech, 1880
Undated quotes, from the same article:
In wars between great nations, the gods still interfere; but in prize fights, the best man with an honest referee, is almost sure to win.
Let me tell you . . . it is far more important to build a home than to erect a church. The holiest temple beneath the stars is a home that love has built. And the holiest altar in all the wide world is the fireside . . .
Defending himself against a charge of blasphemy:
To enslave the minds of men, padlocks upon their lips — that is blasphemy.
When asked about advocates of the new morality and free love:
Let them spend their time in examining each other’s sexual organs and in letting ours alone.
On politics:
. . . a low dirty scramble, through misrepresentation, slander, falsehood, and filth, and success brings nothing but annoyance & fear of defeat next time.
An anecdote about his failed bid to run for governor as a Republican:
A friend visiting Ingersoll’s office saw a copy of Thomas Paine’s The Age of Reason, a book often denounced by nineteenth-century churchmen. “How much did this cost you?” the friend asked him. “The governorship of Illinois.”
And finally:
If there is no other life, we should make the best of this. If there is another life, we should still make the best of this.

A great speaker who rejected the claims of Christ. Missed salvation by a twelve inches, the distance between his head and his heart.
That’s true. One quote of his that I omitted was:
“With soap, baptism is a good thing.”
