In this paper, I explore and defend the idea that musical works are historical individuals. Guy Rohrbaugh (2003) proposes this for works of art in general. Julian Dodd (2007) objects that the whole idea is outré metaphysics, that it is too far beyond the pale to be taken seriously. Their disagreement could be seen as a skirmish in the broader war between revisionists and reactionaries, a conflict about which of metaphysics and art should trump the other when there is a (...) conflict. That dispute is a matter of philosophical methodology as much as it is a dispute about art. I argue that the ontology of works as individuals need not be dunked in that morass. My primary strategy is to show, contra Dodd's accusation, that historical individuals are familiar parts of the world. Although the ontological details are open to debate, it is the standard opinion of biologists is that biological species are historical individuals. So there is no conflict here between fidelity to art and respectable metaphysics. What suits species will fit musical work as well. (shrink)

Discussion of Darwinian evolutionary theory by philosophers has gone through a number of historical phases, from indifference (in the first hundred years), to criticism (in the 1960s and 70s), to enthusiasm and expansionism (since about 1980). This paper documents these phases and speculates about what, philosophically speaking, underlies them. It concludes with some comments on the present state of the evolutionary debate, where rapid and important changes within evolutionary theory may be passing by unnoticed by philosophers.

Given these findings, we argue that each of the most plausible attempts to properly classify bacteriophages into distinct species fail. Mayr's biological species concept fails because there is (...) no useful viral analog to sexual reproduction. Phenetic species concepts fail because they obscure the mosaicism and the rich reticulated viral histories. Phylogenetic species concepts, even when extended to take into account reticulation, fail because there is no non-arbitrary distinction between recombination events that create a new viral species and those that do not. There is good reason to think that bacteriophages, arguably the Earth's most abundant biological agent, evolve without forming species.

The differences between classes and individuals are profound and the fact that biological species are individuals rather than classes provides the basis for organizing knowledge on a causal basis. The class of species is a natural kind and there are laws of nature for this and other classes of natural kinds such as the organism and the molecule. Particular species, like other individuals, function in historical narratives by virtue of laws of nature applying to them. The notion that species can (...) evolve by changing their members is a category mistake. Darwin believed that there is no “essential” difference between species and subspecies in the sense that there is only a quantitative difference between them. The concept of biological species is defined on the basis of a qualitative difference. The rank of taxa can be used to distinguish between important natural kinds. Without such kinds language would become purely referential, and have no “sense” as Frege had put it. (shrink)
