HULL AND MICHAEL RUSE During the past three decades, philosophy of biology has come into its own. It is now a mature discipline. In fact, the classic papers in this discipline are so familiar by now that they need not be reproduced again. Instead, more recent papers by some of the newer members of the profession are included in this anthology. Of the thirtysix papers reproduced here, all but three appeared in the last decade. And members of our profession are not limited to professional philosophers. Rather, a third of the papers in this anthology were authored or coauthored by scientists, primarily biologists. In no other area of philosophy of science have philosophers and scientists cooperated to the extent that they have in philosophy of biology. Of the traditional issues in philosophy of biology, we have included four—adaptation, units of selection, function, and species. As central as adaptation is to evolutionary biology, problems arise with respect to its application. Is it as slippery a notion as Gould and Lewontin in their classic paper claim, or is it no different in kind from other fundamental concepts in biology? Fitness has played such an extensive role in philosophy of biology that some critics refer to our discipline derisively as 'the philosophy of fitness'. In this anthology an equally important issue—the levels at which Selection occurs—is discussed at some length. On no other issue have philosophers and biologists cooperated to greater mutual benefit. Over the years two distinct senses of 'function' have emerged in the philosophical literature—Cummins functions and Wright functions. Can they be merged into a single, unambiguous usage, as Philip Kitcher suggests? As in the case of function, one would think that nothing new could possibly be said about the species problem. However, the papers included here show that this is not the case. There is something new under the sun. Phylogenetic species concepts are nothing if not novel. Finally, although development surely deserves to be a central issue in the philosophy of biology, it has been all but ignored until quite recently. As the two papers
