Incurably religious, that is the best way to describe the mental condition of so many people.

I have been at work for some time building an apparatus to see if it is possible for personalities which have left this earth to communicate with us.

Being busy does not always mean real work. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence, and honest purpose, as well as perspiration. Seeming to do is not doing.

There will one day spring from the brain of science a machine or force so fearful in its potentialities, so absolutely terrifying, that even man, the fighter, who will dare torture and death in order to inflict torture and death, will be appalled, and so abandon war forever.

Sleep is like a drug. Take too much at a time and it makes you dopey. You lose time and opportunities.

Opportunity is missed by most people because it is dressed in overalls and looks like work.

I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.
