Who is Hans Reichenbach?June 25, 2021
Hans Reichenbach (born September 26, 1891, Hamburg; d. April 9, 1953, Los Angeles) is a contemporary neopositivist thinker who also taught in Turkey, where he took refuge from Nazi Germany.
Reichenbach, who suggested that although science is a completely rational activity, the idea of absolute truth should be abandoned here, he said that we can only talk about probability. Adopting probabilism as an attitude, the philosopher said that the famous verifiability principle of the positivist tradition should also be changed if probabilism is taken as a basis. Reichenbach, who made original contributions to verifiability, distinguished four types of verifiability. These, respectively, are technical verifiability, which comes to the fore in proportion to the level of development of the technique, physical verifiability, which means not contradicting the laws of nature, and logical verifiability, which means immunity from contradiction, and experimental verifiability.
