I think that Ingersoll had all the attributes of a perfect man, and, in my opinion, no finer personality ever existed. Judging from the past, I cannot help thinking that the intention of the Supreme Intelligence that rules the world is to ultimately make such a type of man universal.

I do not believe any type of religion should ever be introduced into the public schools of the United States.

I am long on ideas, but short on time. I expect to live to be only about a hundred.

Focus on how the end-user customers perceive the impact of your innovation - rather than on how you, the innovators, perceive it.

I never view mistakes as failures. They are simply opportunities to find out what doesn't work.
