Two challenges to the very possibility of emergence are addressed, one metaphysical and one logical. The resolution of the metaphysical challenge requires a shift to a process metaphysics, while the logical challenge highlights normative emergence, and requires a shift to more powerful logical tools -- in particular, that of implicit definition. Within the framework of a process metaphysics, two levels of normative emergence are outlined: that of function and that of representation.

Jerry Fodor has proposed a causal theory of meaning based on the notion of a certain asymmetric dependency between the causes of a symbol's tokens. This theory is held to be an improvement on Dennis Stampe's causal theory of meaning and Fred Dretske's information theoretic account, because it allegedly solves what Fodor calls the “disjunction problem”, and does so without recourse to the kind of optimal (ideal) conditions to which Stampe and Dretske appeal. A series of counterexamples is proposed to (...) Fodor's account, which, it is argued, can only be met by reintroducing that same appeal to optimal conditions that he had sought to eliminate. It is then argued that Fodor's notion of asymmetric dependence is not fundamental to the explanation of why a symbol means what it does: on the contrary, the symbol's meaning what it does is explanatorily prior to the obtaining of the asymmetry, so the asymmetry cannot be used to explain the symbol's meaning. Finally, it is argued that the “disjunction problem “ as it is defined by Fodor is not a genuine problem for causal theories of meaning. (shrink)

Samuel Alexander was one of the foremost philosophical figures of his day and has been argued by John Passmore to be one of ‘fathers’ of Australian philosophy as well as a novel kind of physicalist. Yet Alexander is now relatively neglected, his role in the genesis of Australian philosophy if far from widely accepted and the standard interpretation takes him to be an anti-physicalist. In this paper, I carefully examine these issues and show that Alexander has been badly, although understandably, (...) misjudged by most of his contemporary critics and interpreters. Most importantly, I show that Alexander offers an ingenious, and highly original, version of physicalism at the heart of which is a strikingly different view of the nature of the microphysical properties and associated view of emergent properties. My final conclusion will be that Passmore is correct in his claims both that Alexander is significant as one of the grandfather’s of Australian philosophy and that he provides a novel physicalist position. I will also suggest that Alexander’s emergentism is important for addressing the so-called ‘problem of mental causation’ presently dogging contemporary non-reductive physicalists. (shrink)

Fodor’s theory of concepts holds that the psychological capacities, beliefs or intentions which determine how we use concepts do not determine reference. Instead, causal relations of a specific kind between properties and our dispositions to token a concept are claimed to do so. Fodor does admit that there needs to be some psychological mechanisms mediating the property–concept tokening relations, but argues that they are purely accidental for reference. In contrast, I argue that the actual mechanisms that sustain the reference determining (...) concept tokening relations are necessary for reference. Fodor’s atomism is thus undermined, since in order to refer with a concept it is necessary to possess some specific psychological capacities. (shrink)

Accounts of mental content rooted in asymmetric dependence hold, crudely speaking, that the content of a mental representation is the cause of that representation on which all its other causes depend.1 To speak somewhat less crudely, such accounts, hereafter.
