epistemology and the scientific method

William M. Trochim (Cornell University) has put together a research methods knowledge base that contains a good introduction to positivism, post-positivism and critical realism, the difference between induction and deduction, and the concept of validity.


Where the positivist believed that the goal of science was to uncover the truth, the post-positivist critical realist believes that the goal of science is to hold steadfastly to the goal of getting it right about reality, even though we can never achieve that goal!
