An idea is something that won't work unless you do.

To me, the idea and expectation that the day is slowly and surely coming when we will be able to honestly say we are our brother's keeper and not his oppressor is very beautiful .

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

Results? Why, man, I have gotten lots of results! If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is often a step forward.

I owe my success to the fact that I never had a clock in my workroom.

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 am both pleased but astonished by the fact that mankind has not yet begun to use all the means and devices that are available for destruction. I hope that such weapons are never manufactured in quantity.
