A common conception of what it is for one property to “realize” another suggests that it is the realizer property that does the causal work, and that the realized property is epiphenomenal. The same conception underlies George Bealer’s argument that functionalism leads to the absurd conclusion that what we take to be self-ascriptions of a mental state are really self-ascriptions of “first-order” properties that realize that state. This paper argues for a different concept of realization. A property realizes another if (...) its “forward looking” causal features are a subset of those of the property realized. The instantiation of the realizer property will include the instantiation of the property realized; and when the effects produced are due to the causal features of the latter, it is the instantiation of it that is appropriately regarded as their cause. Epiphenomenalism is avoided, and so is Bealer’s absurd conclusion. (shrink)

Sometimes neuroscientists discover distinct realizations for a single psychological property. In considering such cases, some philosophers have maintained that scientists will abandon the single multiply realized psychological property in favor of one or more uniquely realized psychological properties. In this paper, we build on the Dimensioned theory of realization and a companion theory of multiple realization to argue that this is not the case. Whether scientists postulate unique realizations or multiple realizations is not determined by the neuroscience alone, but by (...) the psychological theory under examination. Thus, one might say that, in the splitting or non-splitting of properties, psychology enjoys a kind of autonomy from neuroscience. (shrink)

Issues of identity and reduction have monopolized much of the philosopher of mind’s time over the past several decades. Interestingly, while investigations of these topics have proceeded at a steady rate, the motivations for doing so have shifted. When the early identity theorists, e.g. U. T. Place ( 1956 ), Herbert Feigl ( 1958 ), and J. J. C. Smart ( 1959 , 1961 ), fi rst gave voice to the idea that mental events might be identical to brain processes, (...) they had as their intended foil the view that minds are immaterial substances. But very few philosophers of mind today take this proposal seriously. Why, then, the continued interest in identity and reduction? Th e concern, as philosophers like Hilary Putnam and Jerry Fodor have expressed it, is that a victory for identity or reduction is a defeat for psychology. For if minds are physical, or if mental events are physical events, then psychologists might as well disassemble their laboratories, making room for the neuroscientists and molecular biologists who are in a better position to explain those phenomena once misdescribed as “psychological.” Th e worry nowadays is not that locating thought in immaterial souls will make psychology intractable, but that locating thoughts in material brains will make it otiose.

It is commonly held that objects in the world form natural kinds. Rabbits form a natural kind and so do all pieces of gold. The traditional account of natural kinds asserts that the members of a kind share a common essence. The essence of gold, for example, is its unique atomic structure. That structure occurs in all and only pieces of gold, and it is a property that all pieces of gold must have.
