Pragmatism enjoyed renewed attention after Willard Van Orman Quine and Wilfrid Sellars used a revised pragmatism to criticize logical positivism in the 1960s. Inspired by the work of Quine and Sellars, a brand of pragmatism known sometimes as neopragmatism gained influence through Richard Rorty, the most influential of the late 20th century pragmatists along with Hilary Putnam and Robert Brandom. Contemporary pragmatism may be broadly divided into a strict analytic tradition and a "neo-classical" pragmatism (such as Susan Haack) that adheres to the work of Peirce, James, and Dewey.
