Martin Luther and literacy

Joseph Henrich

No, it was a religious mutation in the Sixteenth CenturyAfter bubbling up periodically in prior centuries, the belief that every person should read and interpret the Bible for themselves began to rapidly diffuse across Europe with the eruption of the Protestant Reformation, marked in 1517 by Martin Luther’s delivery of his famous ninety-five theses. Protestants came to believe that both boys and girls had to study the Bible for themselves to better know their God. In the wake of the spread of Protestantism, the literacy rates in the newly reforming populations in Britain, Sweden, and the Netherlands surged past more cosmopolitan places like Italy and France. Motivated by eternal salvation, parents and leaders made sure the children learned to read.

The sharpest test of this idea comes from work in economics, led by Sascha Becker and Ludger Woessmann. The historical record, including Luther’s own descriptions, suggest that within the German context, Protestantism diffused out from Luther’s base in Wittenberg (Saxony). Using data on literacy and schooling rates in nineteenth-century Prussia, Becker and Woessmann first show that counties with more Protestants (relative to Catholics) had higher rates of both literacy and schooling. So, there’s a correlation. Then, taking advantage of the historical diffusion from Wittenberg, they show that for every 100-km traveled from Wittenberg, the percentage of Protestants in a county dropped by 10%. Then, with a little statistical razzle-dazzle, this patterning allows them to extract the slice of the variation in Protestantism that was, in a sense, caused by the Reformation’s ripples as they spread outward from the epicenter in Wittenberg. Finally, they show that having more Protestants does indeed cause higher rates of literacy and schooling. All-Protestant counties had literacy rates nearly 20 percentage points higher than all-Catholic counties. Subsequent work focusing on the Swiss Reformation, where the epicenters were Zurich and Geneva, reveals strikingly similar patterns.

The Protestant impact on literacy and education can still be observed today in the differential impact of Protestant vs. Catholic missions in Africa and India. In Africa, regions with early Protestant missions at the beginning of the Twentieth Century (now long gone) are associated with literacy rates that are about 16 percentage points higher, on average, than those associated with Catholic missions. In some analyses, Catholics have no impact on literacy at all unless they faced direct competition for souls from Protestant missions. These impacts can also be found in early twentieth-century China.

The notion of universal, state-funded schooling has its roots in religious ideals. As early as 1524, Martin Luther not only emphasized the need for parents to ensure their children’s literacy but also placed the responsibility for creating schools on secular governments. This religiously inspired drive for public schools helped make Prussia a model for public education, which was later copied by countries like Britain and the U.S.

When the Reformation reached Scotland in 1560, John Knox and his fellow reformers called for free public education for the poor and justified this with the need for everyone to acquire the skills to better know God. Having placed the burden for delivering schooling on the government, the world’s first local school tax was established in 1633 CE and strengthened in 1646 CE. This early experiment in universal education may have mid-wifed the Scottish Enlightenment, which produced intellectual luminaries ranging from David Hume to Adam Smith. A century later, the early intellectual dominance of this tiny region inspired France’s Voltaire to write, “we look to Scotland for all our ideas of civilization.” Voltaire, who grew up in a region controlled by Huguenots (French Calvinists), was educated in Jesuit schools, along with other Enlightenment luminaries like Diderot and Condorcet. Rousseau, for his part, likely learned to read from his Calvinist father in the Protestant city-state of Geneva.
