Karl Pfeifer revisits Wittgenstein’s parenthetical allusion in the _Tractatus Logico-Philosophicus_ to the Grimms’ fairytale “The Golden Lads”, confirming that it does not work well as an illustration of the notion of “internal identity” that figures in Wittgenstein’s picture theory. He then proposes alternative ways of understanding the relationship of identity apparent in “The Golden Lads”.

Karl Pfeifer attempts to present a coherent view of panentheism that eschews Pickwickian senses of “in” and aligns itself with, and builds upon, familiar diagrammed portrayals of panentheism. The account is accordingly spatial-locative and moreover accepts the proposal of R.T. Mullins that absolute space and time be regarded as attributes of God. In addition, however, it argues that a substantive parthood relation between the world and God is required. Pfeifer’s preferred version of panpsychism, viz. panintentionalism, is thrown into (...) the mix as an optional add-on. On this account, God is conceived of as a “spiritual field” whose nature can be made more intelligible by regarding “God” as having a mass-noun sense in some contexts. Pfeifer closes with the suggestion that we look to topology and mereology for further development of the position outlined in his paper. (shrink)

There is a long tradition in formal epistemology and in the psychology of reasoning to investigate indicative conditionals. In psychology, the propositional calculus was taken for granted to be the normative standard of reference. Experimental tasks, evaluation of the participants’ responses and psychological model building, were inspired by the semantics of the material conditional. Recent empirical work on indicative conditionals focuses on uncertainty. Consequently, the normative standard of reference has changed. I argue why neither logic nor standard probability theory provide (...) appropriate rationality norms for uncertain conditionals. I advocate coherence based probability logic as an appropriate framework for investigating uncertain conditionals. Detailed proofs of the probabilistic non-informativeness of a paradox of the material conditional illustrate the approach from a formal point of view. I survey selected data on human reasoning about uncertain conditionals which additionally support the plausibility of the approach from an empirical point of view. (shrink)

While Classical Logic (CL) used to be the gold standard for evaluating the rationality of human reasoning, certain non-theorems of CL—like Aristotle’s and Boethius’ theses—appear intuitively rational and plausible. Connexive logics have been developed to capture the underlying intuition that conditionals whose antecedents contradict their consequents, should be false. We present results of two experiments (total n = 72), the first to investigate connexive principles and related formulae systematically. Our data suggest that connexive logics provide more plausible rationality frameworks for (...) human reasoning compared to CL. Moreover, we experimentally investigate two approaches for validating connexive principles within the framework of coherence-based probability logic (Pfeifer & Sanfilippo, 2021). Overall, we observed good agreement between our predictions and the data, but especially for Approach 2. (shrink)

This is the commentary on Richard C. Richards, "Humor and Happiness”, read at the Lighthearted Philosophers' Society 5th Annual Conference, 14 October 2011, Treasure Island, Florida.

Karl Pfeifer argues against Searle's "Connection Principle" which requires that unconscious intentional mental states must be in principle accessible to consciousness.

In "The Logical Form of Action Sentences" Donald Davidson argues that Hans Reichenbach's analysis of action and event sentences is "radically defective." I show that Reichenbach can easily deflect Davidson's objections, thus leaving their respective accounts largely comparable.

Karl Pfeifer argues against the view that an aesthetic experience must be a uniquely special kind of experience by means of an analogy with sexual experiences. Nonetheless, he leaves open the possibility that some aesthetic experiences might still be of a special kind.

Karl Pfeifer distinguishes between humor used extraneously in the delivery of philosophical content and humor intrinsic to the content itself: “Enlivening the delivery isn’t the same as enlivening the content of the delivery.” Using examples from topics in philosophy of mind and moral philosophy he illustrates how humor can be used to make certain ideas more engaging and memorable for students. He also gives an example of what to avoid.

This book is a general defence of Donald Davidson's and G.E.M. Anscombe's 'unifying' approach to the individuation of actions and other events against objections raised by Alvin I. Goldman and others. It is argued that, ironically, Goldman's rival 'multiplying' account is itself vulnerable to these objections, whereas Davidson's account survives them. Although claims that the unifier-multiplier dispute is not really substantive are shown to be unfounded, some room for limited agreement over the ontological status of events is indicated. Davidson's causal (...) criterion of event identity is then defended against charges of triviality or inadequacy. It is concluded that Davidson's criterion is not primarily a criterion for arriving at particular judgments of individuation, but a metaphysical standard for the correctness of such judgments, however arrived at. Contents: Unifiers vs. Multipliers - Davidson's individuation of events - Goldman's act generation - causal, 'by'-relational, and temporal problems - ontology and event constituents - Davidson's causal criterion. This book is unique in providing a detailed survey and analysis of the recent unifier-multiplier dispute, and will be of interest to all researchers in action theory, as well as those working more broadly in metaphysics, philosophy of language, and philosophy of mind.

Proceeding on the basis of reports of a proposal in 2011 to criminalize public flatulence in Malawi, the normative significance of flatulence is considered from the respective standpoints of aesthetics, etiquette, and ethics, and it is indicated how aesthetics and etiquette may themselves also have ethical significance. It is concluded that etiquette and ethics may both require that certain violations of etiquette and ethics should sometimes be ignored.

An interview with Ed Casey where we discuss the intersections of his philosophical work with current political issues, including the Israel-Palestine conflict.

What is it for an attribute to be psychological? One clever and inventive, albeit somewhat Byzantine answer to this vexing philosophical question has lately been proposed by Roderick M. Chisholm. Chisholm’s approach is to take a small number of technical philosophical notions as given and then employ these in a series of definitions which together yield an account of the psychological. I examine Chisholm’s account and show that it doesn’t work.

Abstract. This paper illustrates how philosophy and science may converge and inform one another. I begin with a brief rehearsal of John Morreall’s “formulaic” theory of laughter, that laughter results from a pleasant psychological shift, and of my previously published criticisms and counterproposal that laughter results from titillation (where “titillation” is a semitechnical term). I defend my own position against charges that it is trivial, circular, or vacuous (charges that, if correct, would apply equally to Morreall’s position), showing that these (...) charges are misguided or premature. Then I indicate how my position is reflected in and might be given empirical content by a hypothesis that is already under preliminary experimental investigation in psychology, namely the Darwin-Hecker hypothesis, and also how my position is in harmony with recent work in psychology alleging the discovery of evolutionary antecedents of human laughter in rats.

I suggest that the current interest in philosophical counseling is comparable to the situation in the Sixties when many philosophy graduates entertained false hopes of nonacademic philosophical employment. I describe my own experience as a welfare worker, in the course of which my philosophical training proved useful in various ways; I maintain, though, that there was nothing especially philosophical in this. I then consider some ways in which philosophical counseling might be distinctively philosophical. I conclude that philosophical training, as we (...) know it, is in any case inadequate for philosophical counseling and would need to be supplemented by psychological and other training. (shrink)

WREEN'S PROPOSAL FOR AVOIDING CAUSAL LOOPS IN THE DESCRIPTION OF ACTION IS, I ARGUE, ITSELF LOOPY.

The Darwin-Hecker hypothesis, viz. that laughter induced by tickling and humor share common underlying mechanisms, is so-called in part because of a quotation attributed to Ewald Hecker. However, a German counterpart of the quotation does not appear in the location cited. Some textual sleuthing is undertaken to find out what Hecker actually wrote and where he wrote it.

We present an interdisciplinary approach to study systematic relations between logical form and attacks between claims in an argumentative framework. We propose to generalize qualitative attack principles by quantitative ones. Specifically, we use coherent conditional probabilities to evaluate the rationality of principles which govern the strength of argumentative attacks. Finally, we present an experiment which explores the psychological plausibility of selected attack principles.

Several counterexamples are adduced against the view that surprise is an essential ingredient of humor.

A review of Geoffrey Marnell, Mathematical Doodlings: Curiosities, conjectures, and challenges.

Imprecise probabilities are often modelled with representors, or sets of probability functions. In the recent literature, two ways of interpreting representors have emerged as especially prominent: vagueness interpretations, according to which each probability function in the set represents how the agent's beliefs would be if any vagueness were precisified away; and comparativist interpretations, according to which the set represents those comparative confidence relations that are common to all probability functions therein. I argue that these interpretations have some important limitations. I (...) also propose an alternative—the functional interpretation—according to which representors are best interpreted by reference to the roles they play in the theories that make use of them.

Geoffrey Marnell presents philosophical arguments favoring grammatical descriptivism over grammatical prescriptivism. I argue that his explanation and defence of descriptivism reveal that his descriptivism is itself prescriptivist.

Moral naturalists are often said to have trouble making sense of inter-communal moral disagreements. The culprit is typically thought to be the naturalist’s metasemantics and its implications for the sameness of meaning across communities. The most familiar incarnation of this metasemantic challenge is the Moral Twin Earth argument. We address the challenge from the perspective of analytic naturalism and argue that making sense of inter-communal moral disagreement creates no special issues for this view.

This paper identifies three positions on the relationship between language and experience, the third of which I was not acquainted with before from my reading. It seems absurd.

This document briefly summarizes several objections to Thomas Kuhn on science, including by Feyerabend, Davidson, and Fodor.

According to Frankfurt’s analysis, bullshitting and lying necessarily differ in intention. I argue contra Frankfurt that (i) bullshitting can be lying, and that (ii) bullshitting need involve neither misrepresentation nor intention to deceive. My discussion suggests that bullshit is not capturable by a simple formula and that, although illuminating, Frankfurt’s analysis is limited to one paradigm.

In his Edifying Discourses, Soren Kierkegaard published a sermon entitled ‘The Unchangeableness of God’ in which he reiterated the dogma which dominated Catholic, Protestant and even Jewish expressions of classical supernaturalist theology from the first century A.D. until the advent of process theology in the twentieth century. The dogma that as a perfect being, God must be totally unchanging in every conceivable respect was expressed by Kierkegaard in such ways as: He changes all, Himself unchanged. When everything seems stable and (...) in the overturn of all things, He remains equally unchanged; no change touches Him, not even the shadow of a change; in unaltered clearness He, the father of lights, remained eternally unchanged. 1.

There is wide support in logic, philosophy, and psychology for the hypothesis that the probability of the indicative conditional of natural language, P(if A then B), is the conditional probability of B given A, P(B|A). We identify a conditional which is such that P(if A then B)=P(B|A) with de Finetti's conditional event, B|A. An objection to making this identification in the past was that it appeared unclear how to form compounds and iterations of conditional events. In this paper, we illustrate (...) how to overcome this objection with a probabilistic analysis, based on coherence, of these compounds and iterations. We interpret the compounds and iterations as conditional random quantities which, given some logical dependencies, may reduce to conditional events. We show how the inference to B|A from A and B can be extended to compounds and iterations of both conditional events and biconditional events. Moreover, we determine the respective uncertainty propagation rules. Finally, we make some comments on extending our analysis to counterfactuals. (shrink)

According to comparativism, degrees of belief are reducible to a system of purely ordinal comparisons of relative confidence. (For example, being more confident that P than that Q, or being equally confident that P and that Q.) In this paper, I raise several general challenges for comparativism, relating to (i) its capacity to illuminate apparently meaningful claims regarding intervals and ratios of strengths of belief, (ii) its capacity to draw enough intuitively meaningful and theoretically relevant distinctions between doxastic states, and (...) (iii) its capacity to handle common instances of irrationality. (shrink)

Timelines is an inquiry into the nature of time, both as an apparent feature of the external physical world and as a fundamental feature of our experience of ourselves in the world. The principal argument of Timelines is that our coventional ideas about time are largely mistaken and that what we think of as independent physical time is actually our calibration of a certain relation between events. Namely, the relation between time-keeping events and the causal sequential differences of physical processes (...) which are real and independent of us. (shrink)

According to the preference-centric approach to understanding partial belief, the connection between partial beliefs and preferences is key to understanding what partial beliefs are and how they’re measured. As Ramsey put it, the ‘degree of a belief is a causal property of it, which we can express vaguely as the extent to which we are prepared to act on it’ The Foundations of Mathematics and Other Logical Essays, Routledge, Oxon, pp 156–198, 1931). But this idea is not as popular as (...) it once was. Nowadays, the preference-centric approach is frequently dismissed out-of-hand as behaviouristic, unpalatably anti-realist, and/or prone to devastating counterexamples. Cases like Eriksson and Hájek’s :183–213, 2007) preferenceless Zen monk and Christensen’s :356–376, 2001) other roles argument have suggested to many that any account of partial belief that ties them too closely to preferences is irretrievably flawed. In this paper I provide a defence of preference-centric accounts of partial belief. (shrink)

This paper responds to Kathleen Stock’s attempt to explain a puzzling fact, at least from her standpoint: widespread assertions that some people who are biologically male are women and some people who are biologically female are men. She regards these assertions as made while immersed in a fiction. Stock rejects an alternative explanation – that a lot of these people have read Judith Butler or 1970s feminism. Clarifying that explanation reveals it to be not so easy to dismiss.

Perceptual experience is often said to be transparent; that is, when we have a perceptual experience we seem to be aware of properties of the objects around us, and never seem to be aware of properties of the experience itself. This is a introspective fact. It is also often said that we can infer a metaphysical fact from this introspective fact, e.g. a fact about the nature of perceptual experience. A transparency theory fills in the details for these two facts, (...) and bridges the gap between them. We have three aims: to scrutinize Michael Tye’s transparency theory :137–151, 2002; Consciousness revisited: materialism without phenomenal concepts, MIT Press, Cambridge, 2009; Philos Stud 170:39–57, 2014a), introduce a new transparency theory, and advance a meta-theoretical hypothesis about the interest, and import, of transparency theories.

There are philosophers and literary figures who write on a variety of topics. I suppose I do as well. Here I present two personal worries about the advice to become a narrow specialist.

In this paper, I present the problem of the poor king, from combining Descartes and Rousseau.

A brief handout summarizing Andrew Lang's criticisms of Frazer.

This paper presents an alternative interpretation of what Milan Kundera tells us about the contents of the ostriches’ speech, which does not involve a satirical puncturing of the ominous atmosphere. Their talk sounds like human talk earlier in the book because they are being turned into parrots.

This paper responds to Jane Tompkins’ statement “Not long ago… I urged a large roomful of women to ‘get theory’ because I thought that doing theory would admit us to the big leagues.” I propose that what is called “continental theory” provides some schemas which are helpful. One can perceive through them and try to fill out the details, such as a deconstructive schema.

In this paper, I present a metaphysical solution to the all-or-nothing problem, which rejects the description of the choices in favour of lower-level descriptions.

In this brief paper, I present a paradox of the unnew, derived from nineteenth and early twentieth century fiction, and consider an obvious solution.

What did Max Gluckman actually say about apparently structureless societies? I introduce a fictional example to make sense of what he says regarding the Tonga.
