“The measure of intelligence is the ability to change.”

“Intelligence is not measured by the mind's ability to compute, but by the heart's will to contrive.”

“Intelligence is the ability to adapt to change. ”

“Engagement, and its relationship to the accumulation and processing of information, is a little-studied phenomenon, representing as it does, individual skills rather than those that can be measured in a group of people. Currently, our understanding and measurement of human intellectual capacity is oriented toward group skills and toward activities that can be elicited on command, regardless of the state of engagement. Indeed, being able to engage one's focus on the questions of the examiner, rather than on one's own interest, is the primary measure of test-taking ability, and test-taking ability is the primary measure of intelligence. When we find that animals do not do well when compared to people in this way, we must not assume that we have really measured their intellect. Perhaps we have measured only our own limited ability to engage them.”

“Intelligence does not mean infallibility, nor does it mean immobility. Intelligence means the ability to learn.”

“The measure of wealth is the ability to afford ones' mistakes.”
