This paper is concerned with the content of the causal proportionality constraint. It investigates two general versions of the constraint, namely “horizontal” and “vertical” proportionality. Moreover, it discusses whether proportionality is considered an ontic or an epistemic, i.e. explanatory, constraint on causation in the context of some of the most prominent theories of causation. The following main claims are defended: (1) The horizontal (HP) and the vertical version (VP) of the proportionality constraint are logically independent. (2) HP is implied by (...) some prominent theories of causation, not by others. (3) None of the discussed popular theories of causation contradicts either HP or VP. (4) HP and VP are not ontic or epistemic principles as such; rather, whether they are ontic or epistemic depends on the theories chosen plus background assumptions about the existence of higher-level causes and their non-identity to lower-level ones.

This paper discusses two challenges for a Boolean method for establishing constitutive regularity statements which, according to the regularity theory of mechanistic constitution, form the core of any mechanistic explanation in neuroscience. After presenting the regularity definition for the constitution relation and a methodology for constitutive inference, the paper discusses the problem of full variation of tested mechanistic factors and the problem of informational redundancy. A solution is offered for each problem. The first requires some adjustments to the original theory (...) by introducing the technical notion of a set of types satisfying independent instantiability. The second one is resolved by demonstrating that the problem of informational redundancy is based on a confusion that fails to challenge the theory. It is concluded that the methodology of constitutive inference is consistent and plausible with respect to actual practice in neuroscience. (shrink)

This paper is concerned with the connection between the causal exclusion argument and the supervenience argument and, in particular, with two exclusion principles that figure prominently in these arguments. Our aim is, first, to reconstruct the dialectics of the two arguments by formalizing them and by relating them to an anti-physicalist argument by Scott Sturgeon. In a second step, we assess the conclusiveness of the two arguments. We demonstrate that the conclusion of both the causal exclusion argument and the supervenience (...) argument (a negation of the so called ?non-identity premise?) is not tantamount to the claim that all mental events are identical to physical events and that a cause-supervenience exclusion principle is actually required for the validity of the first stage of the supervenience argument. Moreover, we show that this new exclusion principle makes an epiphenomenalism with respect to mental events an impossible position, and that there are good reasons to believe in its falsity, rendering the supervenience argument inconclusive.
