“Stegenga’s deeply informed and wide-ranging discussions address numerous traditional issues in the philosophy of science, offering original and lucidly defended new alternatives. As he sees, the perspective presented here is likely to illuminate questions beyond the many that he covers. In particular, his elegant account of the norms of scientific assertion brings new precision to controversies about how scientific research can properly affect social policies. Within the academy and more broadly, the proposals and arguments assembled here are likely to do much good.”
