Albert Einstein

I live in that solitude which is painful in youth, but delicious in the years of maturity.

Peace cannot be kept by force; it can only be achieved by understanding.

The important thing is not to stop questioning. Curiosity has its own reason for existing.

Never lose a holy curiosity.

The true sign of intelligence is not knowledge but imagination.

Memory is deceptive because it is colored by today's events.

I never think of the future - it comes soon enough.

Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

The distinction between the past, present and future is only a stubbornly persistent illusion.

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

I do not believe that civilization will be wiped out in a war fought with the atomic bomb. Perhaps two-thirds of the people of the earth will be killed.

He who can no longer pause to wonder and stand rapt in awe, is as good as dead; his eyes are closed.
