Does your job trigger primitive survival instincts? My book presents alternatives.

Those best equipped to compete mercilessly for food, ward off any threat, dominate territory, and seek safety naturally passed along their genes, so these self-centered impulses could only intensify. But sometime after mammals appeared, they evolved what neuroscientists call the limbic system, perhaps about 120 million years ago. Formed over the core brain derived from the reptiles, the limbic system motivated all sorts of new behaviors, including the protection and nurture of young as well as the formation of alliances with other individuals that were invaluable in the struggle to survive. And so, for the first time, sentient beings possessed the capacity to cherish and care for creatures other than themselves.

Although these limbic emotions would never be as strong as the ‘me first’ drives still issuing from our reptilian core, we humans have evolved a substantial hard-wiring for empathy for other creatures, and especially for our fellow humans.
