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.

There is always a better way.

I know this world is ruled by infinite intelligence. Everything that surrounds us- everything that exists - proves that there are infinite laws behind it. There can be no denying this fact. It is mathematical in its precision.

The secret of success is focus of purpose.

If I had not had so much ambition and not tried to do so many things, I probably would have been happier, but less useful.

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.

Be courageous! Have faith! Go forward.
