David Brooks: Evolving Views of Human Behavior

One of my favorite political observers, David Brooks, notes how views of human behavior have changed significantly in recent decades.  These changes raise questions about traditional religious doctrines of sin.  Excerpt:

[...] Over the ages, thinkers have argued that humans are divided between passion and reason, or between the angelic and the demonic.

But now the prevailing view is that brain patterns were established during the millenniums when humans were hunters and gatherers, and we live with the consequences.

Now, it is generally believed, our behavior is powerfully influenced by genes and hormones. Our temperaments are shaped by whether we happened to be born with the right mix of chemicals.

Consciousness has come to be seen as this relatively weak driver, riding atop an organ, the brain, it scarcely understands. When we read that male voles with longer vasopressin genes are more likely to remain monogamous, it seems plausible that so fundamental a quality could be tied to some discrete bit of biology.

This shift in how we see human behavior is bound to have huge effects. [...]
