Causation can be regarded from either an explanatory/epistemic or an ontological viewpoint. From the former, emergent features enter into a host of causal relationships which form a hierarchical structure subject to scientific investigation. From the latter, the paramount issue is whether emergent features provide any novel causal powers, or whether the 'go' of the world is exhausted by the fundamental physical features which underlie emergent phenomena. I argue here that the 'Scientific Picture of the World' (SPW) strongly supports the claim (...) that ontological causation is exhausted in the elementary physical features of the world. A method is developed for distinguishing 'emergent ontological causation' from the epistemological emergent explanatory patterns sanctioned by the SPW, and it is argued that the SPW implies that all emergence is mere epistemological emergence. However, this leads to a paradox when applied to consciousness itself, which turns out to be both epiphenomenal and viewpoint dependent. (shrink)

This paper begins with a summary of an argument for epiphenomenalism and a review of the author's previous work on the self-stultification objection to that view. The heart of the paper considers an objection to this previous work and provides a new response to it. Questions for this new response are considered and a view is developed in which knowledge of our own mentality is seen to differ from our knowledge of external things.

Epiphenomenalism has been criticized with several objections. It has been argued that epiphenomenalism is incompatible with the alleged causal relevance of mental states, and that it renders knowledge of our own conscious states impossible. In this article, it is demonstrated that qualia-epiphenomenalism follows from some well- founded assumptions, and that it meets the cited objections. Though not free from difficulties, it is at least superior to its main competitors, namely, physicalism and interactionism.

Causal compatibilism claims that even though physics is causally closed, and even though mental properties are multiply realizable and are not identical to physical causal properties, mental properties are causal properties nonetheless. This position asserts that there is genuine causation at multiple descriptive/ontological levels; physics-level causal claims are not really incompatible with mentalistic causal claims. I articulate and defend a version of causal compatibilism that incorporates three key contentions. First, causation crucially involves robust patterns of counterfactual dependence among properties.Second, often (...) several distinct such patterns, all subsuming a single phenomenon, exist at different descriptive/ontological levels (e.g., microphysical, neurobiological, macrobiological, and psychological). Third, the concept of causation is governed by an implicit contextual parameter that normally determines a specific descriptive/ontological level as the contextually relevant level, for the context-sensitive semantic evaluation of causal statements.
