I was asked to provide a blurb to Matthew Lund's indispensable book, *N.R. Hanson: Observation, Discovery, and Scientific Change*. It has a very elegant foreword by Hasok Chang that resonates with some recent discussion on this blog. I quote with permission:
"the discipline of philosophy of science is at a critical juncture today. While research in the fiels has surely continued to grow in its quantity and sophistication, many traditional debates seem to be at a standstill, and captivating new ideas are rare. There is also a palpable sense of frustration on the part of many scholars that somehow there are few debates that can still elicit excitement in more than a small fraction of an already small field, not to mention people outside the field. Where introductory courses in philosophy of science are offered, students still flock to them; however, good teachers will know not to introduce too many current debates, as their highly technical and inward-looking nature tend to turn students off. Somehow, after so much good work done in the intervening period, it is still the debates from the time of Hanson's death that most excite students and the educated public--debates with the names of Popper, Kuhn, Lakatos and Feyerabend attach to them."
