Most Famous Austrian Philosophers
Austrian philosophy of the late nineteenth and early twentieth centuries was the home of two of the most consequential developments in modern thought: the Brentano school's revival of intentionality and the logical positivism of the Vienna Circle. Alexius Meinong reopened philosophy of mind and theory of objects in a way that fed directly into phenomenology; Ernst Mach's empiricist philosophy of science set the agenda for the Vienna Circle, where Otto Neurath developed logical positivism and the unified-science program. Ludwig Wittgenstein, born in Vienna, reshaped philosophy twice — first in the Tractatus, then in the Philosophical Investigations. Sigmund Freud, though primarily a psychoanalyst, shaped twentieth-century philosophy of mind and culture; Paul Feyerabend's Against Method became a landmark of post-positivist philosophy of science.
The Austrian tradition is unusual for the density of foundational figures it produced in a single generation. The thinkers below include the founders of phenomenology, logical positivism, and major strands of the philosophy of science.
