According to the so-called 'proportionality principle', causes should be proportional to their effects: they should be both enough and not too much for the occurrence of their effects. This principle is the subject of an ongoing debate. On the one hand, many maintain that it is required to address the problem of causal exclusion and take it to capture a crucial aspect of causation. On the other hand, many object that it renders accounts of causation implausibly restrictive and often reject (...) the principle wholesale. I argue that there is exaggeration on both sides. While one half of the principle is overly demanding, the other half is unobjectionable. And while the unobjectionable half does not block exclusion arguments on its own, it provides a nuanced picture of higher-level causation, fits with recent developments in philosophy of causation, and motivates adjustments to standard difference-making accounts of causation. I conclude that at least half of the proportionality principle is worth taking seriously. (shrink)

The standard objection to dualist theories of mind is that they seemingly cannot account for the obvious fact that mental phenomena cause our behaviour. On the plausible assumption that all our behaviour is physically necessitated by entirely physical phenomena, there appears to be no room for dualist mental causation. Some argue that dualists can address this problem by making minimal adjustments in their ontology. I argue that no such adjustments are required. Given recent developments in philosophy of causation, it is (...) plausible that mental phenomena cause behaviour in standard dualist ontologies. (shrink)

Advancements in machine learning have fuelled the popularity of using AI decision algorithms in procedures such as bail hearings, medical diagnoses and recruitment. Academic articles, policy texts, and popularizing books alike warn that such algorithms tend to be opaque: they do not provide explanations for their outcomes. Building on a causal account of transparency and opacity as well as recent work on the value of causal explanation, I formulate a moral concern for opaque algorithms that is yet to receive a (...) systematic treatment in the literature: when such algorithms are used in life-changing decisions, they can obstruct us from effectively shaping our lives according to our goals and preferences, thus undermining our autonomy. I argue that this concern deserves closer attention as it furnishes the call for transparency in algorithmic decision-making with both new tools and new challenges. (shrink)

Many philosophers argue that exclusion arguments cannot exclude non-reductionist physicalist mental properties from being causes without excluding properties that are patently causal as well. List and Stoljar (2017) recently argued that a similar response to exclusion arguments is also available to dualists, thereby challenging the predominant view that exclusion arguments undermine dualist theories of mind. In particular, List and Stoljar maintain that exclusion arguments against dualism require a premise that states that, if a property is metaphysically distinct from the sufficient (...) cause of an effect, this property cannot be a cause of that effect. I argue that this premise is indeed likely to exclude patently causal properties, but that exclusion arguments against dualism do not require this premise. The relation that enables metaphysically distinct properties to cause the same effect in the relevant way turns out to be tighter than the relation typically posited between dualist conscious properties and their underlying physical properties. It is therefore still plausible that the latter causally exclude the former and that compelling exclusion arguments against dualism can be formulated by using a weaker exclusion premise. I conclude by proposing such a formulation. (shrink)

Some non-reductionists claim that so-called ‘exclusion arguments’ against their position rely on a notion of causal sufficiency that is particularly problematic. I argue that such concerns about the role of causal sufficiency in exclusion arguments are relatively superficial since exclusionists can address them by reformulating exclusion arguments in terms of physical sufficiency. The resulting exclusion arguments still face familiar problems, but these are not related to the choice between causal sufficiency and physical sufficiency. The upshot is that objections to the (...) notion of causal sufficiency can be answered in a straightforward fashion and that such objections therefore do not pose a serious threat to exclusion arguments.

Absences pose a dilemma for theories of causation. Allowing them to be causes seems to make theories too permissive (Lewis, 2000). Banning them from being causes seems to make theories too restrictive (Schaffer, 2000, 2004). An increasingly popular approach to this dilemma is to acknowledge that norms can affect which absences count as causes (e.g., Thomson, 2003; McGrath, 2005; Henne et al., 2017; Willemsen, 2018). In this article, I distinguish between two influential implementations of such ‘abnormality’ approaches and argue that (...) so-called ‘double-prevention mechanisms’ provide counterexamples against both.

In recent epistemology many philosophers have adhered to a moderate foundationalism according to which some beliefs do not depend on other beliefs for their justification. Reliance on such ‘basic beliefs’ pervades both internalist and externalist theories of justification. In this article I argue that the phenomenon of perceptual learning – the fact that certain ‘expert’ observers are able to form more justified basic beliefs than novice observers – constitutes a challenge for moderate foundationalists. In order to accommodate perceptual learning cases, (...) the moderate foundationalist will have to characterize the ‘expertise’ of the expert observer in such a way that it cannot be had by novice observers and that it bestows justification on expert basic beliefs independently of any other justification had by the expert. I will argue that the accounts of expert basic beliefs currently present in the literature fail to meet this challenge, as they either result in a too liberal ascription of justification or fail to draw a clear distinction between expert basic beliefs and other spontaneously formed beliefs. Nevertheless, some guidelines for a future solution will be provided. (shrink)

This article focuses on `therefore' constructions such as ‘The switch is on, and therefore the lights are on’. We submit that the contribution of `therefore’ is to express a dependence as part of the core content of these constructions, rather than being conveyed by conventional implicature (Grice 1975, Potts 2005, Neta 2013) or a triggered presupposition (Pavese 2017, forthcoming, Stokke 2017). We argue that the standard objections to this view can be answered by relying on the general projection hypothesis defended (...) by Roberts et al. (2009) and Simons et al. (2010), leaving our view on solid ground. (shrink)
