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.
Thomas A. EdisonThe inventor can't do it all, you've got to change people. We have an enormous capacity to invent super-machinery. But our desire to install the device is weak. Human inertia is the problem, not invention. Something in man makes him resist change.
Thomas A. EdisonWhen we learn how to store electricity, we will cease being apes ourselves; until then we are tailless orangutans. You see, we should utilize natural forces and thus get all of our power. Sunshine is a form of energy, and the winds and the tides are manifestations of energy. Do we use them? Oh, no! We burn up wood and coal, as renters burn up the front fence for fuel. We live like squatters, not as if we owned the property.
