The only true wisdom is in knowing you know nothing.

The more I see, the less I know for sure.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

People who boast about their I.Q. are losers.

The most important knowledge is that which guides the way you lead your life.

I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

We should seek the greatest value of our action.
