Nothing that's good works by itself, you've got to make the damn thing work.

When you have exhausted all possibilities, remember this - you haven't.

Until man duplicates a blade of grass, nature can laugh at his so called scientific knowledge.

Each time you fail, you have eliminated another wrong option.

We don't know a millionth of one percent about anything.

Nature is what we know. We do not know the gods of religions. And nature is not kind, or merciful, or loving. If God made me - the fabled God of the three qualities of which I spoke: mercy, kindness, love - He also made the fish I catch and eat. And where do His mercy, kindness, and love for that fish come in? No; nature made us - nature did it all - not the gods of the religions.

We are striking it big in the electric light, better than my vivid imagination first conceived. Where this thing is going to stop Lord only knows.
