Currently, two frameworks of causal reasoning compete: Whereas dependency theories focus on dependencies between causes and effects, dispositional theories model causation as an interaction between agents and patients endowed with intrinsic dispositions. One important finding providing a bridge between these two frameworks is that failures of causes to generate their effects tend to be differentially attributed to agents and patients regardless of their location on either the cause or the effect side. To model different types of error attribution, we augmented (...) a causal Bayes net model with separate error sources for causes and effects. In several experiments, we tested this new model using the size of Markov violations as the empirical indicator of differential assumptions about the sources of error. As predicted by the model, the size of Markov violations was influenced by the location of the agents and was moderated by the causal structure and the type of causal variables. (shrink)

ABSTRACT The tenets of critical and social realism are well supported in the literature. However, researchers following a realist paradigm have concerns about the lack of methodical guidance for qualitative interviewing, despite their affirmation about the importance of in-depth interviews. A conducted review of empirical realist literature provides evidence of an absence of guidance and commonality regarding interview planning practices. To overcome this absence, this paper composes a guiding framework to assist researchers to phrase more appropriate interview questions in realist (...) research. The steps are founded on critical and social realist concepts while guided by methodological realist principles. Its contribution aims to not only improve the practice of realist inquiry methods but also to introduce more research transparency. A more transparent method for interview questions can lead to increased validity and afford replicability of mechanism-based theories resulting from empirical realist research. (shrink)

Extended simples are physical objects that, while spatially extended, possess no actual proper parts. The theory that physical reality bottoms out at extended simples is one of the principal competing views concerning the fundamental composition of matter, the others being atomism and the theory of gunk. Among advocates of extended simples, Markosian’s ‘MaxCon’ version of the theory has justly achieved particular prominence. On the assumption of causal realism, I argue here that the reality of MaxCon simples would entail the reality (...) of irreducible, intrinsic dispositional properties. The existence of dispositional properties in turn has important implications for another central debate in metaphysics, namely that between two major competing views concerning the ontology of laws: dispositionalism versus nomological necessitarianism.

The question of whether there could be a physical object that is necessarily constantly active has a long history, and it has recently arisen again in the literature on dispositions. I examine and critique two proposals for affirming the possibility of such an object. I then advocate a third option, one which is workable if paired with natural-kind essentialism. Finally I briefly outline three possible implications of this view for wider debates concerning the ontology of dispositions and natural kinds.

In recent years, realism?particularly critical realism?has become an important philosophical and methodological foundation for social science. A key feature is that of natural necessity, but this coexists alongside an acceptance of contingency in the social world. I argue in this paper that there cannot be any natural necessity in the social world, but rather the real nature of the social world is that it is contingent. This need not lead to an abandonment of realism, and indeed I argue that a (...) contingent form of realism allows us to bring ontological probability back into realism. (shrink)

Is 'education' a thick epistemic concept? The answer depends, of course, on the viability of the 'thick/thin' distinction, as well as the degree to which education is an epistemic concept at all. I will concentrate mainly on the latter, and will argue that epistemological matters are central to education and our philosophical thinking about it; and that, insofar, education is indeed rightly thought of as an epistemic concept. In laying out education's epistemological dimensions, I hope to clarify the degree to (...) which it makes sense to regard the concept as 'thick'. I also discuss the relationship between philosophy of education and virtue epistemology and the sense in which being educated might itself be thought to be an epistemic virtue. Finally, I urge virtue epistemologists in particular and epistemologists generally to turn their attention to questions of education, to further both the philosophy of education and epistemology itself.

The defence of a process philosophy as the metaphysics for the foundation of social psychology is part of a general defence of scientific realism. Realists, be they classical or neo critical realists hope to construct a dual level science—a phenomenal level resting on a transcendent level required to account for the order and stability to be found in the unfolding of the phenomena. Also required is a driving force or agency. Discursive psychologists argue for a social ontology in which meanings (...) are created and managed by people engaged in projects, made orderly by shared social representations. Concepts like "social structure" are convenient metaphors to describe clusters of discursive practices but should not be interpreted ontologically. Causal powers are revealed in dispositions, which as a matter of logic, must be ascribed to entities self-identical over time. Only persons meet this condition. Discursive social psychology is quasi social in that Vygotsky wise it looks for a social origin for social representations, and quasi personal in that persons are the naturally active beings that drive the patterns of life forward. A defence of neo-critical realism against Professor Ratner's criticisms can only be a more careful statement of the position since his specific criticisms do not address the position I have been advocating.
