If a parsimony criterion may be used to choose between theories that make different predictions, may the same criterion be used to choose between theories that are predictively equivalent? The work of the statistician H. Akaike (1973) is discussed in connection with this question. The results are applied to two examples in which parsimony has been invoked to choose between philosophical theories-Shoemaker's (1969) discussion of the possibility of time without change and the discussion by Smart (1959) and Brandt and Kim (...) (1967) of mind/body dualism and the identity theory. (shrink)

Quine has developed two reasons for thinking that our ontology should not include the ontological category of properties. His first point is that the criterion for individuating properties is unclear, and the second is that postulating the existence of properties would not explain anything. In what follows I critically examine these two themes, which I will call the clarity argument and the parsimony argument. Although I will suggest that these two arguments are defective, I also will try to show that (...) certain related arguments on behalf of the existence of properties are likewise flawed. This will set the stage for the discussion in the fourth section of the perspective provided by evolutionary theory on the question of the ontological status of properties. It will emerge that evolutionary theory provides reason for thinking that properties exist, and, additionally, gives an interesting point of view on the epistemological and metaphysical issues that Quine has addressed.

: As Spinoza presents it, the knowledge of God is knowledge, primarily, of oneself and, secondarily, of other things. Without this know‐ledge, a mind may not consciously desire to persevere in being. That is why Spinoza claims that the knowledge of God is the most useful thing to the mind at IVP28. He claims that the knowledge of God is the highest good, however, not because it is instrumental to perseverance, but because it is also the best among those goods (...) that we seek for their own sakes. It is acquiescentia in se ipso, the highest form of laetitia. (shrink)

The paper discusses Ted Honderich's ?Hypothesis of Psychoneural Correlation?, one of the three fundamental ?hypotheses? of his Theory of Determinism. This doctrine holds that there is a pervasive system of psychoneural laws connecting every mental event with a neural correlate. Various questions are raised and discussed concerning the formulation of the thesis, Honderich's concepts of ?mental? and ?physical?, and the possible grounds for accepting the thesis. Finally, Honderich's response to Donald Davidson's well?known arguments for psychophysical anomalism is discussed.

Part I of this trilogy, Historical and Scientific Setting, set out a general context for selecting a certain subclass of inter-theoretic relations as achieving appropriate explanatory and ontological unification – hence for properly being labelled reductive. Something of the complexity of these relations in real science was explored. The present article concentrates on the role which identity plays in structuring the reduction relation and so in achieving ontological and explanatory unification.
