Max Bense (February 7, 1910 in Strasbourg – April 29, 1990 in Stuttgart) was a German philosopher, writer, and publicist, known for his work in philosophy of science, logic, aesthetics, and semiotics. His thoughts combine natural sciences, art, and philosophy under a collective perspective and follow a definition of reality, which – under the term existential rationalism – is able to remove the separation between humanities and natural sciences.
