Abstract

According to Karl Popper, who is the latest link in the chain of Western rationalist-empiricist debate, knowledge does not have any infallible base in either senses or reason. Taking modern science as the paradigm of human knowledge, he argues that the process of growth of scientic knowledge involves imaginative proposals of hypotheses or conjectures and their refutation on empirical grounds in a continuing series of steps. Thus, scientific knowledge continuously evolves in a series of revolutions whereby the accepted theoretic constructs are falsified, therefore destroyed, and new ones accepted in their place. Experiment, as provoked and controlled stimulation of the senses, plays a critical role in this process of growth and so long as it fails to falsify the hypotheses these are provisionally accepted by the scientists.
