“It is wrong to think that belief in freedom always leads to victory; we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it.”

Those who promise us paradise on earth never produced anything but hell.

Science is most significant as one of the greatest spiritual adventures that man has yet known.

And it implies that if we respect truth, we must search for it by persistently searching for our errors: by indefatigable rational criticism, and self-criticism.

Instead of the greatest happiness for the greatest number, one should demand, more modestly, the least amount of avoidable suffering for all.

I would rather find a single causal law than be the king of Persia!

We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure.

All life is problem-solving.

In my view, aiming at simplicity and lucidity is a moral duty of all intellectuals: lack of clarity is a sin, and pretentiousness is a crime.

He who decides one day that scientific statements do not call for any further test and that they can be regarded as finally verified retires from the game.

The way of science is paved with discarded theories that were once declared self-evident.

The method of learning by trial and error – of learning from our mistakes – seems to be fundamentally the same whether it is practiced by lower or by higher animals, by chimpanzees, or by men of science.

In philosophy methods are unimportant; any method is legitimate if it leads to results capable of being rationally discussed.

In so far as a scientific statement speaks about reality, it must be falsifiable: and in so far as it is not falsifiable, it does not speak about reality.

Theology, I still think, is due to a lack of faith.

Science may be described as the art of systematic oversimplification.

The game of science is, in principle, without end.

While I believe that when you are in the glamour industry, you have to look your best, I also believe being skinny is not ‘hot and happening.’

We believe in the dignity of man as an individual, whatever his race, colour or creed, and his right to better, fuller, and richer life.

I don’t believe in proving a point to anybody. Nobody is that important.

I am inspired by those who have the courage to do things that have never been done before; things that were believed to be impossible.

God didn’t have time to create a nobody, just a somebody. I believe that each of us has God given talents within us waiting to be brought to fruition. Each person is unique and special.

I always believed that my silence on several topics will be an advantage in the long run.

Don’t limit yourself. Many people limit themselves to what they think they can do. You can go as far as your mind lets you. What you believe, remember, you can achieve.

I believe the power to make money is a gift from God to be developed and used to the best of our ability for the good of mankind.
