John Dewey

Born in 1859, Dewey came up through Michigan academia convinced that democracy and ethics were the same problem. In 1896 his paper on the reflex arc helped launch functionalist psychology - the idea that mind was action, not static structure. By the time he reached the University of Chicago he'd founded the Laboratory Schools, a live experiment in progressive pedagogy where children learned by doing and every lesson doubled as a test of his theories. From 1904 to 1930 he taught philosophy at Columbia's Teachers College, writing across epistemology, aesthetics, logic, and social theory, always circling back to the same obsession: democracy required more than voting rights, it required a public capable of thinking together. He spent half a century arguing that schools and civil society were the engines of that capability, and that without them the ethical ideal collapsed.
