My opinions about human nature are shared by many psychologists, linguists, and biologists, not to mention philosophers and scholars going back centuries.

There's a misconception that survival of the fittest means survival of the most aggressive. The adjective 'Darwinian' used to refer to ruthless competition; you used to read that in business journals. But that's not what Darwinian means to a biologist; it's whatever leads to reproductive success.

In a high tech world the cure for the tragic shortcomings and perilous fallacies of human intuition is education, but education in economics, evolutionary biology, probability and statistics - unfortunately most High School and College curricula have barely changed since Medieval times!

Maybe philosophical problems are hard not because they are divine or irreducible or meaningless or workaday science, but because the mind of Homo sapiens lacks the cognitive equipment to solve them. We are organisms, not angels, and our minds are organs, not pipelines to the truth. Our minds evolved by natural selection to solve problems that were life-and-death matters to our ancestors, not to commune with correctness ot to answer any question we are capable of asking.

If you give people literacy, bad ideas can be attacked and experiments tried, and lessons will accumulate.

If we are not to abandon values such as peace and equality, or our commitments to science and truth, then we must pry these values away from claims about our psychological makeup that are vulnerable to being proven false.

If anything, Powerpoint, if used well, would ideally reflect the way we think.
