In epistemology, I believe there is actually tiny difference between regarding scientific knowledge as an objective correspondence between theory and reality and seeing it as a man-made myth of nature. This book helps to explain how this seemingly absurd—but logical as I shall argue—interpretation makes sense in the 20th century Western philosophy of science. The western philosophy of science in the 20th century, from the early logical empiricism to the historicalism represented by Kuhn, to the late theory of scientific knowledge sociology, is arguably a logical progressing of modern epistemology. This book reveals the very epistemological dilemma facing Western though, that is absolute rationalism inevitably leads to absolute relativism.
