Intelligence is based on how efficient a species became at doing the things they need to survive.

I happen to feel that the degree of a person's intelligence is directly reflected by the number of conflicting attitudes she can bring to bear on the same topic.

There are no great limits to growth because there are no limits of human intelligence, imagination, and wonder.

I don't think the intelligence reports are all that hot. Some days I get more out of the new york times.

Failure is simply the opportunity to begin again, this time more intelligently.
