The costs of an ignorance of science are nor just practical ones like misbegotten policies, forgone cures, and a unilateral disarmament in national competitiveness. There is a moral cost as well. It is an astonishing fact about our species that we understand so much about the history of the universe. the forces that make it tick, the stuff it's made of; the origin of living things, and the machinery of life. A failure to nurture this knowledge shows a philistine indifference to the magnificent achievements humanity is capable of; like allowing a great work of art to molder in a warehouse.

Why are empirical questions about how the mind works so weighted down with political and moral and emotional baggage?

I think students should know something about religion as a historical phenomenon, in the same way that they should know something about socialism and humanism and the other great ideas that have shaped political philosophies and therefore the course of human events.

Gossip is certainly one of the things that language is useful for, because it's always handy to know who needs a favor, who can offer a favor, who's available, who's under the protection of a jealous spouse. And being the first to get a piece of gossip is like engaging in insider trading: You can capitalize on an opportunity before anyone else can.
