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)

I show how Sir William Rowan Hamilton’s philosophical commitments led him to a causal interpretation of classical mechanics. I argue that Hamilton’s metaphysics of causation was injected into his dynamics by way of a causal interpretation of force. I then detail how forces are indispensable to both Hamilton’s formulation of classical mechanics and what we now call Hamiltonian mechanics (i.e., the modern formulation). On this point, my efforts primarily consist of showing that the contemporary orthodox interpretation of potential energy is (...) the interpretation found in Hamilton’s work. Hamilton called the potential energy function the “force-function” because he believed that it represents forces at work in the world. Various non-historical arguments for this orthodox interpretation of potential energy are provided, and matters are concluded by showing that in classical Hamiltonian mechanics, facts about the potential energies of systems are grounded in facts about forces. Thus, if one can tolerate the view that forces are causes of motion, then Hamilton provides one with a road map for transporting causation into one of the most mathematically sophisticated formulations of classical mechanics, viz., Hamiltonian mechanics.

A strongly deterministic theory of physics is one that permits exactly one possible history of the universe. In the words of Penrose (1989), "it is not just a matter of the future being determined by the past; the entire history of the universe is fixed, according to some precise mathematical scheme, for all time.” Such an extraordinary feature may appear unattainable in a world like ours. In this paper, I show that it can be achieved in a simple way and (...) discuss its implications for metaphysics and philosophy of science, including natural properties, free will, explanation, and modality. First, I propose a precise definition of strong determinism. Next, I discuss its philosophical ramifications and a toy example. Finally, I provide a realistic example of a strongly deterministic (and simple) physical theory---the Everettian Wentaculus. A surprising consequence is that whether or not our world is strongly deterministic may be empirically underdetermined. (shrink)

I argue for constraining the nomological possibility space of temporal experiences and endorsing the Succession Requirement for agents. The Succession Requirement holds that the basic structure of temporal experience must be successive for agentive subjects, at least in worlds that are law-like in the same way as ours. I aim to establish the Succession Requirement by showing non-successively experiencing agents are not possible for three main reasons, namely that they (1) fail to stand in the right sort of causal relationship (...) to the outcomes of their actions, (2) exhibit the wrong sort of epistemic status for agency, and (3) lack the requisite agentive mental attitude of intentionality. I conclude that agency is incompatible with non-successive experience and therefore we should view the successive temporal structure of experience as a necessary condition for agency. I also suggest that the Succession Requirement may actually extend beyond my main focus on agency, offering preliminary considerations in favor of seeing successive experience as a precondition for selfhood as well. The consequences of the Succession Requirement are wide-ranging, and I discuss various implications for our understanding of agency, the self, time consciousness, and theology, among other things.

A “contrastive explanation” explains not only why some event A occurred, but why A occurred as opposed to some alternative event B. Some philosophers argue that agents could only be morally responsible for their choices if those choices have contrastive explanations, since they would otherwise be “luck infested”. Assuming that contrastive explanations cannot be offered for causally undetermined events, this requirement entails that no one could be held responsible for a causally undetermined choice. Such arguments challenge incompatibilism, since they entail (...) that causal determinism is a prerequisite for moral responsibility. However, I argue that for a significant class of choices, even if we stipulate that they are determined, we will be unable to provide a relevant contrastive explanation. Hence causal determinism is no remedy for luck infestation, and compatibilists do not fare much better than incompatibilists in the face of this requirement. This should serve to weaken its philosophical appeal. (shrink)

Despite the moral underpinnings of Karl Popper’s philosophy, he has not presented a well-established moral theory for critical rationalism (CR). This paper addresses the ontological status of _moral agents_ as part of a research program for developing a moral theory for CR. It argues that moral agents are _selves_ who have achieved the cognitive capacity of _personhood_ through an evolutionary scenario and interaction with the environment. This proposal draws on Popper’s theory of the self and his theory of three worlds, (...) which offer both epistemological and ontological insights into the emergence and evolution of _moral agents_. The paper also discusses some of the consequences of this proposal for the _objectivity_ and _criticizability_ of moral judgments and the moral agency of artificial intelligence. It concludes by suggesting some directions for future research on the epistemological and ontological problems of ethics in CR. (shrink)

Changing concepts, understood as social constructs and facets of linguistic expressions, and likewise the mechanisms of change and the dynamicity of their contents, cannot be adequately analysed without a holistic perspective of a language system on the one hand, and a multi-layered perspective of conversational interaction on the other. I take on board a case study of the concept humanism, in particular in its relation to speciesism, to argue for such a broad perspective when discussing concept revision, including its deliberate (...) and automatic aspects. Section 1 sets out the scene and the objectives, emphasising the importance of metapragmatic concerns. In Sect. 2, I briefly introduce some relevant terms and debates surrounding concepts, lexemes, and their dynamicity. Section 3 moves to the question of the foundations of meaning and points out the importance of addressing it in the context of these debates. Section 4 contains the case study of the concept humanism and the insights it offers for carving out the boundaries of inquiry into the life of a concept, focusing on the importance of broadly understood propositional content and the non-propositional overlay as they are dynamically constructed in discourse—and, as such, on the importance of metapragmatic concerns. Section 5 concludes and reiterates my plea against carving out fields of inquiry based on narrowly understood pursuits. (shrink)

In his 1956 book ‘The Direction of Time’, Hans Reichenbach offered a comprehensive analysis of the physical ground of the direction of time, the notion of physical cause, and the relation between the two. I review its conclusions and argue that at the light of recent advances in physics Reichenbach analysis provides the best account for the physical underpinning of these notions. I integrate results in cosmology, and on the physical underpinning of records and agency into Reichenbach’s account, and discuss (...) which questions it leaves open. (shrink)
