Albert Sabin

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

We cannot solve our problems with the same thinking we used when we created them.

The true sign of intelligence is not knowledge but imagination.

Try not to become a man of success, but rather try to become a man of value.

The only source of knowledge is experience.

A person who never made a mistake never tried anything new.

Education is not the learning of facts, but the training of the mind to think.

The measure of intelligence is the ability to change.

Logic will get you from A to B. Imagination will take you everywhere.

The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.

The only thing that interferes with my learning is my education.

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

The mind is everything. What you think you become.
