What is Intelligence ?

Mechanism to solve problem is one of the very basic definitions. 

Following are the different aspects of intelligence:

• Information 
• Memory
• Learning 
• Knowledge 
• Creativity 
• The use of physical tools
• The ability to plan for the future Cultural intelligence

The relationship between learning and intelligence:

Although learning and intelligence can be conceptually distinguished in terms of formal definitions and measurements, a review of evidence on the relationship between individual differences in measures of learning and of intelligence suggests that no clear distinction can be made between the cognitive processes that contribute to individual differences in these two different realms

Intelligence and memory:

Learning and memory are closely related concepts. Learning is the acquisition of skill or knowledge, while memory is the expression of what you’ve acquired. Another difference is the speed with which the two things happen. If you acquire the new skill or knowledge slowly and laboriously, that’s learning. If acquisition occurs instantly, that’s Even though scientists have highlighted the differences and connections between all those aspects of intelligence, 52 experts agreed on the following definition of intelligence in 1994

Intelligence is a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test-taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings—"catching on," "making sense" of things, or "figuring out" what to do.

No single person could ever build a space rocket or particle accelerator. But thanks to our ability to work together and to share knowledge across generations, we can overcome challenges beyond any single individual's ability. Almost no progress would have been possible without the ability to work together and give knowledge onto the next generations. Compared to our ancestors who lived gens of thousands of years ago, our brain didn’t really grew since then. What did grow however, is the knowledge that we are able to store and to pass to the next generation.

It would at first sight seem that these tremendous advances indicate a comparable growth of intelligence; that although our bodies have made no significant advance (such as separate pathways for the lungs and stomach, better drainage for facial sinuses, improved resistance to cold or damp- the possibilities are numerous) our intellects, by a mysterious alchemy, have developed to a degree that places us on a level different from that of our Neolithic ancestors. This is not so: there is ample reason to believe that Neolithic man was just as intelligent as ourselves- the difference between our ways of life is due to the fact that we are more widely informed. What we have achieved is the ability to store the facts we harvest by means that a real improvement on passing them on by word of mouth. The number of facts the average man stores in his mind today is probably no greater than it ever has been and, due to the cushioning of civilization, probably of decreasing basic importance.
