Most introductions to Philosophy of Science use a similar approach. They start with the development of philosophy of science in this century, including chapters on logical positivism, critical rationalism, the received view, Kuhn's theory of paradigms, and Lakatos' theory of research programs. Some books present arguments for and against methodological monism -- the view that one method should be used in all sciences. Relatively little attention is paid to the question what the proper methods for the humanities are (a German Introduction by Helmut Seiffert forms an exception). Work addressing that specific problem, like Hermeneutics and Psychological Theory, a volume edited by Messer, Woolfolk and Sass (1988), is usually not seen as belonging to the field of philosophy of science proper.
