Darwin, Marx, Wagner

One of the great turning points in modern history came in 1859 when Darwin's Orgin of Species, Marx's Critique of Political Economy, and Wagner's Tristan and Isolde made their first appearance. As THE scientist, THE sociologist, and THE artist of the late nineteenth century, Darwin, Marx, and Wagner dominate the epoch, and their theories epitomize a century of thought which continues, as a single stream of influence, down to the present day.
