The psychoanalysis of neurotics has taught us to recognize the intimate connection between wetting the bed and the character trait of ambition.Sigmund Freud
I think that intelligence is such a narrow branch of the tree of life - this branch of primates we call humans. No other animal, by our definition, can be considered intelligent. So intelligence can't be all that important for survival, because there are so many animals that don't have what we call intelligence, and they're surviving just fine.Neil deGrasse Tyson
Let's say intelligence is your ability to compose poetry, symphonies, do art, math and science. Chimps can't do any of that, yet we share 99 percent DNA. Everything that we are, that distinguishes us from chimps, emerges from that one-percent difference.Neil deGrasse Tyson
Computers have proved to be formidable chess players. In fact, they've beaten our top human chess champions.Neil deGrasse Tyson
In the animal kingdom, one of the keys to survival is to outwit your enemies. And when you're surrounded by carnivores, one of the best strategies is to fade into the background and disappear.Neil deGrasse Tyson
Keep in mind that if you take a tour through a hospital and look at every machine with on and off switch that is brought into the service of diagnosing the human condition, that machine is based on principles of physics discovered by a physicist in a machine designed by an engineer.Neil deGrasse Tyson
I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.Neil deGrasse Tyson
It is only the enlightened ruler and the wise general who will use the highest intelligence of the army for the purposes of spying, and thereby they achieve great results.Sun Tzu
