Popper's Critiques and the Problems of Falsifiability

Falsifiability was one of the influential theories in the field of the philosophy of science in the twentieth century. However, its success is mostly due to its negative role, namely, in criticizing the opponents. The author in this article reviews Popper’s critiques of such theories as positivism and determinism, while reflecting on the consequences of rejecting Darwin’s hypothesis of evolution as scientific. At the end, the article concludes that falsifiability enjoys no acceptable success on thepositive side, and is unable to correctly explain the role of observation in science and its relation to theory.
