The Blank Slate: The Modern Denial of Human Nature

by Steven Pinker

Instead, the Tragic Vision looks to systems that produce desirable outcomes even when no member of the system is particularly wise or virtuous. Market economies, in this vision, accomplish that goal: remember Smith’s butcher, brewer, and baker providing us with dinner out of self-interest rather than benevolence. No mastermind has to understand the intricate flow of goods and services that make up an economy in order to anticipate who needs what, and when and where. Property rights give people an incentive to work and produce; contracts allow them to enjoy gains in trade. Prices convey information about scarcity and demand to producers and consumers, so they can react by following a few simple rules—make more of what is profitable, buy less of what is expensive—and the “invisible hand” will do the rest. The intelligence of the system is distributed across millions of not-necessarily-intelligent producers and consumers, and cannot be articulated by anyone in particular.
