Biology Neuroscience

The thesis of Human Diversity is that advances in genetics and neuroscience are overthrowing an intellectual orthodoxy that has ruled the social sciences for decades. The core of the orthodoxy consists of three dogmas: Gender is a social construct. Race is a social construct. Class is a function of privilege. The problem is that all three dogmas are half-truths. They have stifled progress in understanding the rich texture that biology adds to our understanding of the social, political, and economic worlds we live in. It is not a story to be feared. But it is a story that needs telling.

In a fascinating tour of creativity and the brain, Nancy Andreasen, professor of psychiatry at the University of Iowa and the winner of the National Medal of Science, explores how the human brain achieves creative breakthroughs--in art, literature, music, and science--the role of genes and environment, extraordinary creativity vs. ordinary creativity, and the question of genius and insanity.

We remember the admonition of our mothers: "Treat others as you want them to treat you." But what if being nice was something we were inclined by nature to do anyway? Renowned neuroscientist Donald Pfaff upends our entire understanding of ethics and social contracts with an intriguing proposition: the Golden Rule is hardwired into the human brain. Pfaff, the researcher who first discovered the connections between specific brain circuits and certain behaviors, contends that the basic ethics governing our everyday lives can be traced directly to brain circuitry.
