Is the philosophy of science dead? (Introduction)

Physicists think so, philosophers don't. A good but long review article of the debate:-http://www.scientificamerican.com/article/physicists-are-philosophers-too/?WT.mc_id=SA_WR_20150513-Later that year Krauss had a friendly discussion with philosopher Julian Baggini in The Observer, an online magazine from The Guardian. Although showing great respect for science and agreeing with Krauss and most other physicists and cosmologists that there isn't “more stuff in the universe than the stuff of physical science,” Baggini complained that Krauss seems to share “some of science's imperialist ambitions.” Baggini voices the common opinion that “there are some issues of human existence that just aren't scientific. I cannot see how mere facts could ever settle the issue of what is morally right or wrong, for example.”-Krauss does not see it quite that way. Rather he distinguishes between “questions that are answerable and those that are not,” and the answerable ones mostly fall into the “domain of empirical knowledge, aka science.” As for moral questions, Krauss claims that they only be answered by “reason...based on empirical evidence.” Baggini cannot see how any “factual discovery could ever settle a question of right and wrong.”-Nevertheless, Krauss expresses sympathy with Baggini's position, saying, “I do think philosophical discussion can inform decision-making in many important ways—by allowing reflections on facts, but that ultimately the only source of facts is via empirical exploration.”-****
We are not sure how model-dependent realism differs from instrumentalism. In both cases physicists concern themselves only with observations and, although they do not deny that they are the consequence of some ultimate reality, they do not insist that the models describing those observations correspond exactly to that reality. In any case, Hawking and Mlodinow are acting as philosophers—epistemologists at the minimum—by discussing what we can know about ultimate reality, even if their answer is “nothing.”-All of the prominent critics of philosophy whose views we have discussed think very deeply about the source of human knowledge. That is, they are all epistemologists. The best they can say is they know more about science than (most) professional philosophers and rely on observation and experiment rather than pure thought—not that they aren't philosophizing. Certainly, then, philosophy is not dead. That designation is more aptly applied to pure-thought variants like those that comprise cosmological metaphysics.-To me it seems reasonable to debate if one can get something from nothing.
