| ==== Q: What is Intelligence? A: A Natural Phenomenon==== | ==== What is Intelligence? ==== |
| | \\ Intelligence | A phenomenon encountered in nature. Intelligence is a phenomenon with good examples in the natural world, but may have more forms than the examples from nature. \\ The only one that //everyone// agrees on to call 'intelligent': **humans**. | | | Why The Question Matters | It is important to know what you're studying and researching! \\ A researcher selects topics in nature; an engineer decides what problem to solve. \\ AI has elements of both these approaches. | |

| | ==== Key Terms ==== |
| | Natural Intelligence | Intelligence as it appears in nature. Some kinds of animals are considered "intelligent", or at least some behavior of some individuals of an animal species other than humans are deemed indicators of intelligence. | | | Natural Intelligence | Intelligence as it appears in nature.

However, each of these denotes a large and ill-defined collection of capabilities or features. There is no definite collection of nec- essary or sufficient conditions (nor any disjunction of conjunctions) that can be used to define such terms."

| | Be Careful with Definitions! | By definition, a definition of a phenomenon is useful only if it helps you in your research. So a good definition is fantastic: It advances research and helps with progress towards the goal of understanding a novel phenomenon. But what is the effect of a bad definition? | | | Be Careful with Definitions! | By definition, a definition of a phenomenon is useful only if it helps you in your research.

| | 'Insufficient' | means that it cannot be guaranteed, and in fact, can never be guaranteed to be sufficient to guarantee that goals are achieved. The reason it cannot is that an agent in the physical world can never know for //sure// that it has everything needed to achieve its goals. | | | 'Insufficient' | means that it cannot be guaranteed, and in fact, can never be guaranteed to be sufficient to guarantee that goals are achieved.

| | | ...it can really learn //anything//, but it takes the duration of the universe for it to learn each of those things? | Lifetime | |
| | | ...it can only learn one task, but it can get better at it than any other system or controller in the universe? | Generality | |
| | | ...it can only learn one task at a time, and can only learn something else by forgetting what it knew before? | Generality | |
| | | ...it can respond to anything and everything correctly, but always responds too late? | Response Time | |
| | | ...it can learn to do anything //in principle//, but is in principle impossible to implement? | Implementation | |
| | | ...it can learn to do anything //in principle//, but requires as much energy as is available in the whole universe to run? | Implementation | |
| | | ...it can learn and do anything, but it cannot do anything entirely on its own and always requires help from the outside? | Autonomy | |
| | | ...it can learn anything, but it cannot learn whether or not to trust its own abilities? | Autonomy | |
| | | ...it can learn anything, but cannot handle any variation on what it has learned? | Autonomy | |
