“Lincoln, who enjoyed less than one year of formal schooling, was essentially self-educated. He read widely in nineteenth-century political economy, including the works of the British apostle of economic liberalism John Stuart Mill and the Americans Henry Carey and Francis Wayland. Although these writers differed on specific policies—Carey was among the most prominent advocates of a high tariff while Wayland favored free trade—all extolled the virtues of entrepreneurship and technological improvement in a modernizing market economy. (Wayland, the president of Brown University and a polymath who published works on ethics, religion, and philosophy, made no direct reference to slavery in his 400-page tome, Elements of Political Economy, but did insist that people did not work productively unless allowed to benefit from their own labor, an argument Lincoln would reiterate in the 1850s.)”
