Essays on Actions and Events, Ch 11 Clarendon Press 1980

In this essay author lays out the support for the theory of anamalous monism, which is needed because he wants to make the following triad consistent:

1) At least some mental events interact causally with physical events.
2) Where there is causality, there is a description of deterministic lawfulness.
3) There are no strict deterministic laws that predict or explain mental events.

These seem inconsistent and all plausible. The first part of the paper deals with giving a view of physicalism that is consistent with 3. Author lays out an identity theory where mental events are identical to physical ones, and events are tokens 'unrepeatable, dated individuals'. (pg209) There is some difficulty with including bona fide mental events among all the physical ones. (pg210-12) Author proposes to consider intentionality as the criterion. (pg211) The downside of this approach is that it denies there are 'strict laws connecting the mental and the physical', a kind-kind identity (pg212-13). The different kinds of of monism and dualism are described, with author taking anamalous monism and briefly describing it.

The second part of the paper defends the downside of the theory that there are no strict psychophysical laws. This seems to be a case of philosophy encroaching on science, which author wants to deny. (pg216-219) Author uses an analogy of how using behaviorism in trying to define belief has failed us, and that a more general point is that the holism in interpretation of the mental is what restricts the possibility of psychophysical laws. Author also delves into the grue / bleen problem. Author lays out a distinction between homonomic and heteronomic generalizations, heteronomic being ones that, in order to describe the lawfulness of a generalization, needs to shift between vocabularies. (pg219) Author discusses the problem of 'longer-than': it is only a problem until there are a whole 'set of axioms, laws or postulates', e.g., the idea of rigid, macroscopic objects that 'longer-than' is a part of, that underwrite lawlike statements of the physical sciences. (pg221) The ideal in the physical sciences is to have a homonomic set of descriptions, yet much of it is still heteronomic, especially all the areas that link the mental to the physical. (pg221-2) 'There cannot be tight connections between the realms if each is to retain allegiance to its proper source of evidence' (pg222).

The last part of the paper proves the identity of the mental to the physical, or at least those mental events that cause physical ones and vice versa. Mental events that enter into causal relations with physical ones must be subject to physical law (of causation), thus have a physical description, hence is physical. (pg224) Note that this only works for mental events that interact with physical ones via causation.
