Intelligence is what you use when you don't know what to do.

The true sign of intelligence is not knowledge but imagination. I have no special talent. I am only passionately curious.

The true sign of intelligence is not knowledge but imagination.

Intelligence isn't just about what you know. It is also the ability to avoid being your own bottleneck.

• If you lack the skills, be willing to look foolish while you learn them.
• If you lack the connections, be courageous enough to reach out and build them.
• If you feel uncertain, be bold enough to figure it out along the way.

Many people have the ability, but they talk themselves out of trying.

The real test of ‘knowledge’ is not whether it is true, but whether it empowers us.

Knowledge is power. The real test of knowledge is not whether it is true but whether it empowers us. Scientists usually assume that no theory is 100% correct. Truth, consequently, is a poor test for knowledge. The real test is utility. A theory that enables us to do new things constitutes knowledge.

If, as I maintain and firmly believe, there is no objective definition of intelligence, and what we call intelligence is only a creation of cultural fashion and subjective prejudice, what the devil is it we test when we make use of an intelligence test?

The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.
One should, for example, be able to see that things are hopeless and yet be determined to make them otherwise.

Knowing a great deal is not the same as being smart; intelligence is not information alone but also judgement, the manner in which information is co-ordinated and used. Still, the amount of information to which we have accessed is one index of our intelligence.

Textbook intelligence is not true intelligence. It only marks a man good at memorization.

... intelligence is not just a matter of acting or behaving intelligently. Behavior is a manifestation of intelligence, but not the central characteristic or primary definition of being intelligent. A moment's reflection proves this: You can be intelligent just lying in the dark, thinking and understanding. Ignoring what goes on in your head and focusing instead on behavior has been a large impediment to understanding intelligence and building intelligent machines

The only real test of intelligence is if you get what you want out of life.

The universe is an intelligence test
