My replies to Errol Lord, Adam Pautz, and Peter Railton's commentaries on The Rationality of Perception (2017).

This paper responds to two arguments that have been offered against the positing of ‘i-desires’, imaginative counterparts of desire supposedly involved in fiction, pretence, and mindreading. The Introspection Argument asks why, if there are both i-desires and desires, the distinction is so unfamiliar and hard to draw, unlike the relatively clear distinctions between perception and mental imagery, or belief and belief-like imagining. The Accountability Argument asks how it can make sense to treat merely imaginative states as revealing of someone’s psychology, (...) the way we do with responses to fiction. I argue that carefully considering the relationship between other states and their imaginative counterparts sheds light on how we should expect i-desires to differ from desires, and suggests that we may often be in states that are _indeterminate_, in limbo between the two categories. This indeterminacy explains why the distinction is often hard to draw, and why these states can be revealing about us even without (determinately) being real desires. (shrink)

One of the most exciting debates in philosophy of imagination in recent years has been over the epistemic use of imagination where imagination epistemically contributes to justifying beliefs and acquiring knowledge. This paper defends “generationism about imagination” according to which imagination is a generative source, rather than a preservative source, of justification. In other words, imagination generates new justification above and beyond prior justification provided by other sources. After clarifying the generation/preservation distinction (Section 2), we present an argument for generationism (...) about imagination, which can be divided into two parts; the philosophical part and the empirical part. In the philosophical part of our argument (Section 3), we claim that generationism about imagination follows from what we call “INACCESSIBILITY”. According to INACCESSIBILITY, imagination is properly constrained by the imaginative constrainers (i.e., the prior representations that constrain the development of a scenario in imagination) to which non-imaginative belief-forming processes do not have access. In the empirical part of our argument (Section 4), we claim that INACCESSIBILITY is plausible in light of relevant studies and theories in the empirical literature, especially the literature on mental simulation (Section 4.1), core cognition (Section 4.2), and intuitive physics (Section 4.3).

Recently, various philosophers have argued that we can obtain knowledge via the imagination. In particular, it has been suggested that we can come to know concrete, empirical matters of everyday significance by appropriately imagining relevant scenarios. Arguments for this thesis come in two main varieties: black box reliability arguments and constraints-based arguments. We suggest that both strategies are unsuccessful. Against black-box arguments, we point to evidence from empirical psychology, question a central case-study, and raise concerns about a (claimed) evolutionary rationale (...) for the imagination's reliability. Against the constraints-based account, we argue that to the extent that it works, this does not give rise to knowledge that is distinctively from the imagination. We conclude by suggesting that the imagination's role in raising possibilities, traditionally seen as part of the context of discovery, can in fact play a role in justification, including as a bulwark against certain sorts of skepticism.

Counterfactuals abound in science, especially when reasoning about and with models. This often requires entertaining counterfactual conditionals with nomologically or metaphysically impossible antecedents, namely, counternomics or counterpossibles. In this paper I defend the make-believe view of scientific counterfactuals, a naturalised fiction-based account of counterfactuals in science which provides a means to evaluate their meanings independently of the possibility of the states of affairs their antecedents describe, and under which they have non-trivial truth-values. Fiction is here understood as imagination (in contrast (...) with its most typical association with falsity), characterised as a propositional attitude of pretense or ‘make-believe’ (Walton 1990). The application of this theory to scientific counterfactuals makes their evaluation a game of make-believe: a counterfactual is (fictionally) true iff its antecedent and the rules of the game prescribe the imagining of its consequent (Kimpton-Nye 2020). The result is a practice-based account of counterfactuals and counterfactual reasoning in science which incorporates insights from theoretical and experimental analytic philosophy as well as cognitive science. This way, the make-believe view of scientific counterfactuals shows that the evaluation of scientific counterfactuals is none other than a question of scientific representation in disguise. (shrink)

Psychedelic substances elicit powerful, uncanny conscious experiences that are thought to possess therapeutic value. In those who undergo them, these altered states of consciousness often induce shifts in metaphysical beliefs about the fundamental structure of reality. The contents of those beliefs range from contentious to bizarre, especially when considered from the point of view of naturalism. Can chemically induced, radically altered states of consciousness provide reasons for or play some positive epistemic role with respect to metaphysical beliefs? In this paper, (...) I discuss a view that has been underexplored in recent literature. I argue that psychedelic states can be rationally integrated into one’s epistemic life. Consequently, updating one’s metaphysical beliefs based on altered states of consciousness does not have to constitute an instance of epistemic irrationality. (shrink)

This paper discusses the phenomenological method’s reliance on imaginative procedures in view of ethnomethodological research. While ethnomethodology has often been seen in continuity with Alfred Schütz’ phenomenological sociology, it mainly parts ways with phenomenology by stressing that the decisive details structuring mutual understanding (gestures, bodily expressions, or the myriad trifles that regulate casual conversation) are „not imaginable, but can only be found out”. This paper reflects from a phenomenological perspective on what such a claim entails by first delineating this line (...) of criticism from other objections raised against the use of imaginative procedures in phenomenology and by showing how this line of questioning departs from the core philosophical debates concerning imaginabilitiy and unimaginability in the Kantian tradition. Further on, the paper offers an in-depth interpretation of the aforementioned ethnomethodological claim in order not only to outline its methodological implications for phenomenology, but also to show that it involves possible key insights for understanding interaction, which phenomenology needs to take into account despite its eidetic scope.

The philosophical literatures on models and thought experiments have been developing exponentially, and independently, for decades. This independence is surprising, given how similar models and thought experiments are. They each have “lives of their own,” they sit between theory and experience, they are important for both pedagogy and cutting-edge science, they galvanize conceptual changes and paradigm shifts, and they involve entertaining imaginary scenarios and working out what happens. Recently, philosophers have begun to highlight these similarities. This entry aims at taking (...) the idea further, by trying to systematically identify places where insights from one literature can be taken up in the other. Along the way, important differences will also be highlighted. (shrink)

A number of authors have asked what it takes for a course of mental imagery to be epistemically or practically useful. This paper addresses a prior question, namely, the difference between courses of imagination that are realistic and those that are fantastic. One approach, suggested by recent literature concerning the utility of imagery, holds that a course of imagination represents realistically if and only if the course of events represented conforms to certain accepted constraints. Against this it will be argued (...) that the constraints cannot be both permissive enough and restrictive enough. An alternative approach adds as a necessary condition that realistic courses of imagination are constructed in accordance with certain procedures on the basis of remembered perceptions. (shrink)
