Two conceptions of voluntary action in the Nicomachean Ethics

It is nearly universally agreed among commentators that according to Aristotle's account of voluntary action in the Nicomachean Ethics (NE), only voluntary actions are blameworthy. I argue for a qualified rejection of this assumption: some actions that Aristotle counts as blameworthy do not meet the criteria for voluntariness set out in NE 3.1. However, in NE 3.5 and elsewhere, one finds a broader conception of voluntary action, and it is true that, for Aristotle, an action must be voluntary on this broader conception in order to be blameworthy. While the narrow conception only counts actions that are under the agent's direct control as voluntary, the broader conception includes also actions that are under the agent's indirect control. The compresence of these two conceptions in the NE is not simply a matter of sloppiness on Aristotle's part. Rather, he has good philosophical reasons for employing both.     

Conditionals,Context, and the Suppression Effect

Modus ponens is the argument from premises of the form If A, then B and A to the conclusion B (e.g., from If it rained, Alicia got wet and It rained to Alicia got wet). Nearly all participants agree that the modus ponens conclusion logically follows when the argument appears in this Basic form. However, adding a further premise (e.g., If she forgot her umbrella, Alicia got wet) can lower participants’ rate of agreement—an effect called suppression. We propose a theory of suppression that draws on contemporary ideas about conditional sentences in linguistics and philosophy. Semantically, the theory assumes that people interpret an indicative conditional as a context‐sensitive strict conditional: true if and only if its consequent is true in each of a contextually determined set of situations in which its antecedent is true. Pragmatically, the theory claims that context changes in response to new assertions, including new conditional premises. Thus, the conclusion of a modus ponens argument may no longer be accepted in the changed context. Psychologically, the theory describes people as capable of reasoning about broad classes of possible situations, ordered by typicality, without having to reason about individual possible worlds. The theory accounts for the main suppression phenomena, and it generates some novel predictions that new experiments confirm.     

Functions of External Cues in Prospective Memory

Abstract

A simulation of an air traffic control task was the setting for an investigation of the functions of external cues in prospective memory. External cues can support the triggering of an action or memory for the content of the action. We focused on memory for the content, and manipulated the temporal characteristics of the external cue to disentangle two possible functions the cue can support: (1) an external cue visible during a retention interval could support rehearsal of the to-be-performed action; (2) an external cue visible at the end of a retention interval could support retrieval of the to-be-performed action. Two experiments were conducted that converge on the same conclusion: the primary function of an external cue is to support retrieval. Implications for the design of a computer interface to present prospective cues are discussed.     

Locating Gunky Water and Wine

Can material objects be weakly located at regions of spacetime and yet fail to be exactly located anywhere? In this paper, I discuss a case which, at least according to one interpretation, answers affirmatively: the case of blending gunky water and wine, in gunky space. Perhaps after such a blend, the water and wine aren't exactly located anywhere while being weakly located at the location of the blend and any region which overlaps it. I show that the case is interesting and complicated, and has consequences for some ideas found in papers by Daniel Nolan and Josh Parsons. 1 1 Many thanks to Kyle Dickey, Peter Fritz, Cody Gilmore, Jeremy Goodman, John Hawthorne, Shieva Kleinschmidt, Anna Marmodoro, Bernard Molyneux, Daniel Nolan, Josh Parsons, Ted Shear, Adam Sennet, Nat Tabris, Andy Yu, Gabriel Uzquiano, Diego Tajer, an anonymous referee at Ratio, and an audience at the University of Oxford for helpful comments and discussion.
     

The No-No Paradox Is a Paradox

The No-No Paradox consists of a pair of statements, each of which ‘says’ the other is false. Roy Sorensen claims that the No-No Paradox provides an example of a true statement that has no truthmaker: Given the relevant instances of the T-schema, one of the two statements comprising the ‘paradox’ must be true (and the other false), but symmetry constraints prevent us from determining which, and thus prevent there being a truthmaker grounding the relevant assignment of truth values. Sorensen's view is mistaken: situated within an appropriate background theory of truth, the statements comprising the No-No Paradox are genuinely paradoxical in the same sense as is the Liar (and thus, on Sorensen's view, must fail to have truth values). This result has consequences beyond Sorensen's semantic framework. In particular, the No-No Paradox, properly understood, is not only a new paradox, but also provides us with a new type of paradox, one which depends upon a general background theory of the truth predicate in a way that the Liar Paradox and similar constructions do not.     

Determinism and Inevitability

The paper discusses one of the central arguments in Dennett’s Freedom Evolves, an argument designed to show that a deterministic universe would not necessarily be a universe of which it could truly be said that everything that occurs in it is inevitable. It suggests that on its most natural interpretation, the argument is vulnerable to a serious objection. A second interpretation is then developed, but it is argued that without placing more weight on etymological considerations than they can really bear, it can deliver only a significantly qualified version of the conclusion that Dennett is seeking. Moreover, the new argument depends upon an intermediate conclusion which, on the face of it, looks to be self-contradictory. Dennett is able to avoid the appearance of self-contradiction only by utilising a possible-worlds framework for the understanding of “could have done otherwise” judgements which is argued to be unsatisfactory. It is suggested that a different framework might hold the key to understanding how better to defend these same judgements from purported threats from determinism.     

Cartwright On Explanation And Idealization

Nancy Cartwright (1983, 1999) argues that (1) the fundamental laws of physics are true when and only when appropriate ceteris paribus modifiers are attached and that (2) ceteris paribus modifiers describe conditions that are almost never satisfied. She concludes that when the fundamental laws of physics are true, they don't apply in the real world, but only in highly idealized counterfactual situations. In this paper, we argue that (1) and (2) together with an assumption about contraposition entail the opposite conclusion — that the fundamental laws of physics do apply in the real world. Cartwright extracts from her thesis about the inapplicability of fundamental laws the conclusion that they cannot figure in covering-law explanations. We construct a different argument for a related conclusion — that forward-directed idealized dynamical laws cannot provide covering-law explanations that are causal. This argument is neutral on whether the assumption about contraposition is true. We then discuss Cartwright's simulacrum account of explanation, which seeks to describe how idealized laws can be explanatory. This revised version was published online in July 2006 with corrections to the Cover Date.     

Quantum-mechanical Statistics and the Inclusivist Approach to the Nature of Particulars

There have been attempts to derive anti-haeccetistic conclusions from the fact that quantum mechanics (QM) appeals to non-standard statistics. Since in fact QM acknowledges two kinds of such statistics, Bose-Einstein and Fermi-Dirac, I argue that we could in the same vein derive the sharper anti-haeccetistic conclusion that bosons are bundles of tropes and fermions are bundles of universals. Moreover, since standard statistics is still appropriate at the macrolevel, we could also venture to say that no anti-haecceitistic conclusion is warranted for ordinary objects, which could then tentatively be identified with substrates. In contrast to this, however, there has been so far no acknowledgement of the possibility of inclusivism, according to which ontological accounts of particulars as widely different as those can possibly coexist in one world picture. The success of the different statistics in physics at least calls for a revision in this respect.     

Aural and Visual Sources of Validity in Structured Employment Interviews

This study tests effects of aural and visual cues on the validity of structured interviews. We recorded simulated job interviews with 40 managers from three utility companies on videotape. Supervisors provided performance ratings. Undergraduate research participants (N = 194) saw and heard the videotapes, heard them without the picture, or saw them without the sound and rated interviewees accordingly. Approximately 6 participants rated each interviewee in each condition of cue availability. Performance ratings and participants′ pooled ratings correlated .36 when they could hear and see the interviews, .33 when they could only hear the interviews, and .32 when they could only see the interviews. Interview ratings based on sight alone correlated .53 with interview ratings based on sound alone. One explanation is that aural cues, visual cues, and supervisory performance ratings all reflect true differences between interviewees in traits related to management effectiveness. Another is that interviewers and supervisors make the same mistakes when interpreting implications of aural cues and visual cues for management effectiveness.     

Knowledge Under Threat

Many contemporary epistemologists hold that a subject S’s true belief that p counts as knowledge only if S’s belief that p is also, in some important sense, safe. I describe accounts of this safety condition from John Hawthorne, Duncan Pritchard, and Ernest Sosa. There have been three counterexamples to safety proposed in the recent literature, from Comesaña, Neta and Rohrbaugh, and Kelp. I explain why all three proposals fail: each moves fallaciously from the fact that S was at epistemic risk just before forming her belief to the conclusion that S’s belief was formed unsafely. In light of lessons from their failure, I provide a new and successful counterexample to the safety condition on knowledge. It follows, then, that knowledge need not be safe. Safety at a time depends counterfactually on what would likely happen at that time or soon after in a way that knowledge does not. I close by considering one objection concerning higher‐order safety.     

Domain-sensitivity

In this paper, I argue that there are good motivations for a relativist account of the domain-sensitivity of quantifier phrases. I will frame the problem as a puzzle involving what looks like a logically valid inference, yet one whose premises are true while the conclusion is false. After discussing some existing accounts, literalist and contextualist, I will present and argue for an account that may be said to be relativistin the following sense: (i) a domain of quantification is required for determining truth value, but is idle in determining semantic content, and (ii) the same sentence, as used on one and the same occasion, may receive different truth values relative to different domains.     

Russell's Early Theory of Denoting

The ancient Greek method of analysis has a rational reconstruction in the form of the tableau method of logical proof. This reconstruction shows that the format of analysis was largely determined by the requirement that proofs could be formulated by reference to geometrical figures. In problematic analysis, it has to be assumed not only that the theorem to be proved is true, but also that it is known. This means using epistemic logic, where instantiations of variables are typically allowed only with respect to known objects. This requirement explains the preoccupation of Greek geometers with questions as to which geometrical objects are ‘given’, that is, known or ‘data’, as in the title of Euclid's eponymous book. In problematic analysis, constructions had to rely on objects that are known only hypothetically. This seems strange unless one relies on a robust idea of ‘unknown’ objects in the same sense as the unknowns of algebra. The Greeks did not have such a concept, which made their grasp of the analytic method shaky.
