Is a Universal Definition of Intelligence and Life Possible?

Jensen's use of the word 'intelligence'

Can anyone provide a positive definition of intelligence

• To avoid confusion between 'intelligence' and the g factor, I have used the word 'intelligence' in an open-ended, generic sense to include various behavioral and cognitive phenomena recognized by psychologists as stimulus apprehension, perception, discrimination, generalization, learning, memory, insight, reasoning, problem solving, and the like. These capacities are the subject matter of both experimental cognitive psychology and artificial intelligence, which can work hand-in-hand in their attempts to model these phenomena, without reference to species differences (i.e., comparative psychology), individual differences (i.e., differential psychology), or neural underpinnings (i.e., cognitive neuropsychology).[/color]

Additionally, we might take note that the M-W Unabridged defines an animal as "an organism of the kingdom Animalia being characterized by ... greater irritability..." It might seem that an organism endowed with Jensen's above-listed traits of intelligent behavior would be more susceptible than a plant to irritation by its environment.
