Intelligence has been defined in many different ways including, but not limited to, abstract thought, understanding, self-awareness, communication, reasoning, learning, having emotional knowledge, retaining, planning, and problem solving.
Intelligence is most widely studied in humans, but has also been observed in animals and in plants. Artificial intelligence is the simulation of intelligence in machines.
Within the discipline of psychology, various approaches to human intelligence have been adopted. The psychometric approach is especially familiar to the general public, as well as being the most researched and by far the most widely used in practical settings.
Famous quotes containing the word intelligence:
“In the mythus a superhuman intelligence uses the unconscious thoughts and dreams of men as its hieroglyphics to address men unborn.”
—Henry David Thoreau (18171862)
“... it is a great mistake to confuse conventionality with simplicity ... it takes a good deal of intelligence and a great many inhibitions to follow a social code.”
—Katharine Fullerton Gerould (18791944)
“It is not, truly speaking, the labour that is divided; but the men: divided into mere segments of menbroken into small fragments and crumbs of life, so that all the little piece of intelligence that is left in a man is not enough to make a pin, or a nail, but exhausts itself in making the point of a pin or the head of a nail.”
—John Ruskin (18191900)
