Revisiting Quine on Truth by Convention

In “Truth by Convention” W.V. Quine gave an influential argument against logical conventionalism. Even today his argument is often taken to decisively refute logical conventionalism. Here I break Quine’s arguments into two—(i) the super-task argument and (ii) the regress argument—and argue that while these arguments together refute implausible explicit versions of conventionalism, they cannot be successfully mounted against a more plausible implicit version of conventionalism. Unlike some of his modern followers, Quine himself recognized this, but argued that implicit conventionalism was explanatorily idle. Against this I show that pace Quine’s claim that implicit conventionalism has no content beyond the claim that logic is firmly accepted, implicit rules of inference can be used to distinguish the firmly accepted from the conventional. As part of my case, I argue that positing syntactic rules of inference as part of our linguistic competence follows from the same methodology that leads contemporary linguists and cognitive scientists to posit rules of phonology, morphology, and grammar. The upshot of my discussion is a diagnosis of the fallacy in Quine’s master critique of logical conventionalism and a re-opening of possibilities for an attractive conventionalist theory of logic.     

The essential invisibility of trauma and the need for repetition commentary on Shabad's “resentment,indignation, entitlement”;

This paper assesses the implications of Grünbaum's critique of Freud's “science”; for a discussion of the relation between theory and practice in psychoanalytically oriented psychotherapy. Guided by the work of the French sociologist, Bourdieu, it places Grünbaum's argument within a logic of intellectualism—a framework that tends to instrumentalize reason and romanticize practice, delineating the well‐known territories of objectivism and subjectivism. Grünbaum's arguments within this logic are taken to be rhetorical maneuvers—such as valorizing the tally argument and then debunking it—aimed at rejuvenating an objectivistic approach to theory and practice. Grünbaum is successful insofar as much of the debate generated by his views accepts the terms of his intellectualist bias. It is suggested, however, that these are terms that have long been suspect; that, indeed, it was Freud who helped bring them into question; and that there is a broader framework of discourse that relativizes intellectualism within a dialectical opposition to “participationism.”; A form of rationality founded in a nonconceptual knowledge of practice has begun to emerge within this more inclusive discourse under such rubrics as “social constructivist”; and “relational”; approaches to psychotherapy. It is argued that within the therapy situation a kind of “practical reason”; can mitigate the controlling, instrumental authority of intellectualism as well as the collusive, sentimental servility of participationism.

[T]he theoretician's claim to an absolute viewpoint, the “perspec‐tiveless view of all perspectives”; as Leibnitz would have put it, contains the claim to a power, founded in reason, over particular individuals, who are condemned to error by the partisan partiality of their individual viewpoints [Bourdieu, 1990, pp. 28–29]1 ^lThe work of sociologist Pierre Bourdieu (1977, 1990; Bourdieu and Wacquant, 1992) focuses on a scientific study of human interaction that is cognizant of the pitfalls of the conflicting poles within intellectualism of “objectivism”; and “subjectivism"—both of which are rejected. and redefined relative to the recognition of a distinct “logic of practice.”; I hope that the perceived significance of this work to the understanding of psychoanalytic practice will justify my extensive use of quotations.      

Sadomasochism as Make‐Believe

In “Rethinking Sadomasochism,” Patrick Hopkins challenges the “radical” feminist claim that sadomasochism is incompatible with feminism. He does so by appeal to the notion of “simulation.” I argue that Hopkins's conclusions are generally right, but they cannot be inferred from his “simulation” argument. I replace Hopkins's “simulation” with Kendall Walton's more sophisticated theory of “make‐believe.” I use this theory to better argue that privately conducted sadomasochism is compatible with feminism.     

On Quine’s Translation Argument

Quine's translation argumnent figures centrally in his views on logic. The goal of this paper is to get clear on that argument. It can be interpreted as an argument to the effect that one should never translate somebody’s speech as going against a law of the translator’s logic. Key to this reading of the translation argument is the premise that one should never translate somebody's speech such that their speech is unintelligible. Ultimately, it is my aim to reject this reading. I argue that only a weaker conclusion—one that says “not most of the time” instead of the stronger “never”—should be attributed to Quine. Accordingly, I propose and defend a weaker version of the first premise that better coheres with the weaker conclusion of the translation argument. Instead of the claim that one should never translate somebody’s speech such that their speech is unintelligible I argue that we should only ascribe to Quine the claim that one should not most of the time translate somebody’s speech in a way that makes it unintelligible. I go on to  sum up the results of my discussion and respond to a criticism of my reading.

     

WHAT DO BELIEF ASCREBERS REALLY MEAN? A REPLY TO STEPHEN SCHIFFER

Stephen Schiffer has recently claimed that the currently popular “hidden-indexical” theory of belief reports is an implausible theory of such reports. His central argument for this claim is based on what he refers to as the “meaning-intention” problem. In this paper, I claim that the meaning-intention problem is powerless against the hidden-indexical theory of belief reports. I further contend that the theory is in fact a plausible theory of such reports.     

Book Review

The main purpose of the paper concerns the question of the existence of hard mathematical facts as truth-makers of mathematical sentences. The paper defends the standpoint according to which hard mathematical facts do not exist in semantic models of mathematical theories. The argumentative line in favour of the defended thesis proceeds as follows: (i) slingshot arguments supply us with some reasons to reject various ontological theories of mathematical facts; (ii) there are two ways of blocking these arguments: through the rejection of the principle of extensionality for individual terms (Ext) or through the rejection of the principle of Wittgenstein; (iii) the first way cannot be accepted because it leads to the practice of softening mathematical facts; (iv) the second way, called fine-graining facts, cannot be accepted because it also results in the practice of softening facts. (v) Hence, only soft mathematical facts (SMFs) can be introduced into semantic models of mathematical theories. Because they should be rather interpreted as mental representations of mathematical objects, they no longer satisfy the semantic role of truth-makers in relation to mathematical sentences. The argument formulated in the paper is based on the analysis of mathematical extensions of the basic non-Fregean logic. Sixty-two definitions of potential fact-identity connectives are also presented. The paper's conclusion may be interpreted as undermining the situational paradigm of building semantics for mathematical languages.     

How the World Is Measured Up in Size Experience

I develop a Russellian representationalist account of size experience that draws importantly from contemporary vision science research on size perception. The core view is that size is experienced in ‘body‐scaled’ units. So, an object might, say, be experienced as two eye‐level units high. The view is sharpened in response to Thompson’s (forthcoming) Doubled Earth example. This example is presented by Thompson as part of an argument for a Fregean view of size experience. But I argue that the Russellian view I develop handles the Doubled Earth example in a natural and illuminating way, thereby avoiding the need to posit irreducible experiential ‘modes of presentation’. I also address a kind of neo‐Fregean ‘reference‐fixing’ view of size experience, that shares features with the Russellian view developed. I give reasons for favoring the latter. Finally, I argue that Peacocke’s claim that spatial experience is ‘unit free’ is not persuasive.     

Are beliefs signals?

Eric Funkhouser argues that beliefs can function as social signals. I argue that Funkhouser’s argument for this conclusion rests on a problematic definition of “signal,” and that on standard definitions, the imperceptibility of beliefs disqualifies them from counting as signals. However, I also argue that Funkhouser’s insights about the social functions of beliefs can be true even if his claim that beliefs are signals is false.     

AQUINAS'S ARGUMENT AGAINST SELF-HATRED

Aquinas's argument against the possibility of genuine self‐hatred runs counter to modern intuitions about self‐hatred as an explanatorily central notion in psychology, and as an effect of alienation. Aquinas's argument does not deny that persons experience hatred for themselves. It can be read either as the claim that the self‐hater mistakes what she feels toward herself as hatred, or that, though she hates what she believes is her “self,” she actually hates only traits of herself. I argue that the argument fails on both readings. The first reading entails that all passions are really self‐love, and so is incompatible with Aquinas's own “cognitivist” view of what it is that distinguishes specific passions in experience. The second reading entails that persons have no phenomenal access to “self,” rendering self‐reference—how it is that the self can be an intentional object of conscious mental states—a mystery. Augustine's claim, which Aquinas accepts on authority, that all sin originates in inordinate self‐love seems to entail the impossibility of genuine self‐hatred because both thinkers fail to distinguish between two distinct forms of self‐love: amor concupiscentiae and amor benevolentiae.     

The Open-Endedness of the Set Concept and the Semantics of Set Theory

Some philosophers have argued that the open-endedness of the set concept has revisionary consequences for the semantics and logic of set theory. I consider (several variants of) an argument for this claim, premissed on the view that quantification in mathematics cannot outrun our conceptual abilities. The argument urges a non-standard semantics for set theory that allegedly sanctions a non-classical logic. I show that the views about quantification the argument relies on turn out to sanction a classical semantics and logic after all. More generally, this article constitutes a case study in whether the need to account for conceptual progress can ever motivate a revision of semantics or logic. I end by expressing skepticism about the prospects of a so-called non-proof-based justification for this kind of revisionism about set theory.     

AGAINST LEWIS's NEW THEORY OF CAUSATION: A STORY WITH THREE MORALS

Abstract: A recent paper by David Lewis, “Causation as Influence”, provides a new theory of causation. This paper presents an argument against the theory, using a series of counterexamples that are, I think, of independent interest to philosophers of causation. I argue that (a) the relation asserted by a claim of the form “C was a cause of E” is distinct from the relation of causal influence, (b) the former relation depends very much, contra Lewis, on the individuation conditions for the event E, and (c) Lewis's account is unsatisfactory as an analysis of either kind of relation. The counterexamples presented in this paper provide, I suggest, some insight into the reasons for the failure of counterfactual accounts of causal relations.     

奎因对模态逻辑的批评

奎因对模态逻辑的批评包括：(i)因为模态语境是指称不透明的,所以对其量化纳入没有意义;(ii)一些关于必然真理的经验知识与关于必然性的语言学理论不相容;(iii)模态语境中的量化纳入承诺了“亚里士多德式的本质主义”。丘奇,克里普克和福雷斯达尔对奎因提出了批评。他们提出,模态构造应该是外延上不透明但指称上透明的。奎因式诉诸于模态环境指称不透明的批评,在不采用单称词项的模态逻辑中不成立。他对本质主义的批评引入了一种必然性,但这种必然性没有办法用语言陈述词项进行解释。通过对语言中名称使用的讨论,我们可以看出,有关包含名称的同一性陈述的真值的经验知识,和卡苏洛称之为“一般模态地位”的先验知识是相容的。既然奎因论证了真同一性陈述的必然真是逻辑真,而且所有逻辑真都遵循戴维森式的意义理论（另文讨论）,那么我们可以给出一个关于包含名称的同一性的真陈述的模态地位的先验知识的语言学理论。     

From the fixity of the past to the fixity of the independent

There is an old but powerful argument for the claim that exhaustive divine foreknowledge is incompatible with the freedom to do otherwise. A crucial ingredient in this argument is the principle of the “Fixity of the Past” (FP). A seemingly new response to this argument has emerged, the so-called “dependence response,” which involves, among other things, abandoning FP for an alternative principle, the principle of the “Fixity of the Independent” (FI). This paper presents three arguments for the claim that FI ought to be preferred to FP.

     

Underdetermination and the explanation of theory-acceptance: A response to Samir Okasha

After a thorough examination of the claim that “the underdetermination of theory by evidence forces us to seek sociological explanations of scientists' cognitive choices”, Samir Okasha concludes that the only significant problem with this argument is that the thesis of underdetermination is not adequately supported. Against Okasha, I argue (1) that there is a very good reason to question the inference from the underdetermination of a theory to a sociological account of that theory's acceptance, and (2) that Okasha's own objection to the argument is too weak.     

Contradictory Information: Too Much of a Good Thing

Both I and Belnap, motivated the “Belnap-Dunn 4-valued Logic” by talk of the reasoner being simply “told true” (T), and simply “told false” (F), which leaves the options of being neither “told true” nor “told false” (N), and being both “told true” and “told false” (B). Belnap motivated these notions by consideration of unstructured databases that allow for negative information as well as positive information (even when they conflict). We now experience this on a daily basis with the Web. But the 4-valued logic is deductive in nature, and its matrix is discrete: there are just four values. In this paper I investigate embedding the 4-valued logic into a context of probability. Jøsang’s Subjective Logic introduced uncertainty to allow for degrees of belief, disbelief, and uncertainty. We extend this so as to allow for two kinds of uncertainty—that in which the reasoner has too little information (ignorance) and that in which the reasoner has too much information (conflicted). Jøsang’s “Opinion Triangle” becomes an “Opinion Tetrahedron” and the 4-values can be seen as its vertices. I make/prove various observations concerning the relation of non-classical “probability” to non-classical logic.     

Brown on Mackie: Echoes of the Lottery Paradox

In “The possibility of morality,” Phil Brown considers whether moral error theory is best understood as a necessary or contingent thesis. Among other things, Brown contends that the argument from relativity, offered by John Mackie—error theory’s progenitor—supports a stronger modal reading of error theory. His argument is as follows: Mackie’s is an abductive argument that error theory is the best explanation for divergence in moral practices. Since error theory will likewise be the best explanation for similar divergences in possible worlds similar to our own, we may conclude that error theory is true at all such worlds, just as it is in the actual world. I contend that Brown’s argument must fail, as abductive arguments cannot support the modal conclusions he suggests. I then consider why this is the case, concluding that Brown has stumbled upon new and interesting evidence that agglomerating one’s beliefs can be epistemically problematic—an issue associated most famously with Henry Kyburg’s lottery paradox.     

Laws,causality and the intentional explanation of action

Whether or not an intentional explanation of action necessarily involves law-like statements is related to another question, namely, is it a causal explanation? The Popper-Hempel Thesis, which answers both questions affirmatively, inevitably faces a dilemma between realistic and universalistic requirements. However, in terms of W.C. Salmon’s concept of causal explanation, intentional explanation can be a causal one even if it does not rely on any laws. Based on this, we are able to refute three characteristic arguments for the claim “reason is not a cause of action,” namely, the “proper logical” argument, the “logical relation” argument, and the “rule-following” argument. This rebuttal suggests that the causal relationship between reason and action can provide a justification for intentional explanations.
