Although Ludwig Wittgenstein's famously original and difficult philosophical work never translated into distinct school of thought, it did inspire two of the most influential movemements in 20th century philosophy - logical positivism and ordinary language philosophy. Wittgenstein's influence remains prominent throughout analytic philosophy, emerging in the works of thinkers as diverse as Michael Dummett, Daniel Dennett, John Searle, Donald Davidson, Saul Kripke, and John McDowell.
