Richard McKay Rorty (October 4, 1931 – June 8, 2007) was an American philosopher, historian of ideas, and public intellectual. Educated at the University of Chicago and Yale University, Rorty's academic career included appointments as the Stuart Professor of Philosophy at Princeton University, the Kenan Professor of Humanities at the University of Virginia, and a professor of comparative literature at Stanford University. Among his most influential books are Philosophy and the Mirror of Nature (1979), Consequences of Pragmatism (1982), and Contingency, Irony, and Solidarity (1989). Rorty rejected the long-held idea that correct internal representations of objects in the outside world are a necessary prerequisite for knowledge. Rorty argued instead that knowledge is an internal and linguistic affair; knowledge relates only to our own language.
