Truth,Meaning, and Circularity

It is often argued that the combination of deflationism about truth and the truth-conditional theory of meaning is impossible for reasons of circularity. I distinguish, and reject, two strains of circularity argument. Arguments of the first strain hold that the combination has a circular account of the order in which one comes to know the meaning of a sentence and comes to know its truth condition. I show that these arguments fail to identify any circularity. Arguments of the second strain hold that the combination has a circular explanation of the ideas or concepts of meaning and truth. I show that these arguments identify a genuine, but acceptable, circularity.     

Knowledge, doubt, and circularity

Ernest Sosa??s virtue perspectivism can be thought of as an attempt to capture as much as possible of the Cartesian project in epistemology while remaining within the framework of externalist fallibilism. I argue (a) that Descartes??s project was motivated by a desire for intellectual stability and (b) that his project does not suffer from epistemic circularity. By contrast, Sosa??s epistemology does entail epistemic circularity and, for this reason, proves unable to secure the sort of intellectual stability Descartes wanted. I then argue that this leaves Sosa??s epistemology vulnerable to an important kind of skepticism.     

Undermining, circularity, and disagreement

Sometimes we get what seem to be good reasons for believing that we’ve misevaluated our evidence for a proposition P. In those cases, can we use our evidence for P itself to show that we haven’t misevaluated our evidence for P? I show why doing so appears to employ viciously circular reasoning. However, I then argue that this appearance is illusory in certain cases and that we sometimes can legitimately reason in that way. This claim sheds new light on the nature of epistemic undermining and epistemic circularity. In addition, it has implications for the current debate about the epistemic significance of disagreement. An important and influential position in that debate says that disagreement with others dramatically undermines our justification for a wide range of our opinions (e.g., political, religious, moral, economic, and philosophical opinions). My view on undermining and circularity implies that this position on disagreement rests on a mistake.     

A COMPARISON OF TECHNIQUES WHICH TEST FOR JOB DIFFERENCES

There has been a recent trend in research seeking the most appropriate statistical technique for determining job similarities/differences. Monte Carlo methods were used to analyze more closely the repeated measures analysis of variance and the multivariate analysis of variance in order to add further insight into the viability of these techniques for this purpose. The conventional univariate analysis of variance, the ε-adjusted univariate F test, and the ε-adjusted univariate F test were compared to three multivariate tests (Roy's largest-root criterion, Wilk's likelihood ratio, and the Pillai-Barlett trace) in terms of power and control for Type I error when (1) circularity and homogeneity were met, (2) homogeneity was met but circularity was violated, (3) homogeneity was violated but circularity was met, and (4) both homogeneity and circularity were violated. The efficacy of the techniques was shown to be contingent upon whether the assumptions were met or not. The univariate test proved to be the better technique when circularity was met. The multivariate technique proved to be the better test when homogeneity was met while circularity was violated. The results were mixed when both circularity and homogeneity were violated. Guidelines for selecting a statistical technique which tests for job differences are offered.     

De re modality,generic essences,and science

Conclusion I have taken the traditional problem of the seeming interdependence of identity concepts and essentialistic concepts and the attendant difficulties with circularity as a starting point in my consideration of recent attempts to provide accounts ofde re essences. Having distinguished between theories of individual and generic essences, I have shown how a linguistic device based upon a new approach to referring expressions has, perhaps, provided some advance in the understanding of individualde re essences. I have argued that, however efficacious these linguistic devices may be in dealing with individual essences, they are of no help in dealing with generic essences. I considered, therefore, one of the recent attempts to use science as the arbiter ofde re essences and concluded that such attempts will not, ultimately, solve the traditional problem of circularity. That problem remains, arising in different forms to thwart different attempts to account forde re generic essences.     

Sosa’s Reflective Knowledge: How damaging is epistemic circularity?

The problem of epistemic circularity maintains that we cannot know that our central belief-forming practices (faculties) are reliable without vicious circularity. Ernest Sosa??s Reflective Knowledge (2009) offers a solution to this problem. Sosa argues that epistemic circularity is virtuous rather than vicious: it is not damaging. Contra Sosa, I contend that epistemic circularity is damaging. Section 1 provides an overview of Sosa??s solution. Section 2 focuses on Sosa??s reply to the Crystal-ball-gazer Objection. Section 2 also contends that epistemic circularity does not prevent us from being justified in (e.g.) perceptual beliefs, or from being justified in believing that (e.g.) sense perception is reliable. But, Sect. 3 argues that it does prevent us from being able to satisfactorily show that our central belief-forming practices (faculties) are reliable. That is, epistemic circularity prevents us from distinguishing between reliable and unreliable practices, from guiding ourselves to use reliable practices and avoid unreliable ones, and from defending reliable practices against skepticism. Hence, epistemic circularity is still damaging. The concluding section suggests that this has repercussions for Sosa??s analysis of the value of reflective knowledge.     

HOW TO ANALYSE SUBSTANCE: A REPLY TO SCHNIEDER

In a recent issue of this journal, Benjamin Schnieder has presented an objection to the account of individual substance that we have developed and put to various uses in our works on metaphysics. According to Schnieder's objection, our proposal to analyse this notion of substantiality suffers from a special kind of circularity. In this paper, we give two replies to Schnieder's objection. The first is that a successful analysis is not, in fact, required to avoid the sort of circularity about which Schnieder complains. The second is that our analysis does not involve the alleged circularity.     

悖论的自指性与循环性

本文使用语义网分析悖论与自指性和循环性。主要结论是证明了有穷悖论都是自指的,同时其矛盾性必定基于循环性。我们还证明存在非自指但基于循环性的(无穷)悖论,比如亚布鲁悖论及其一般变形;又证明了存在自指但不基于循环性的(无穷)悖论,比如超穷赫兹伯格悖论和麦基悖论。这表明自指性与循环性对悖论而言是两个不同的概念。     

Truth,Ramsification, and the Pluralist's Revenge

Functionalists about truth employ Ramsification to produce an implicit definition of the theoretical term true, but doing so requires determining that the theory introducing that term is itself true. A variety of putative dissolutions to this problem of epistemic circularity are shown to be unsatisfactory. One solution is offered on functionalists' behalf, though it has the upshot that they must tread on their anti-pluralist commitments.     

Freedom,determinism and circular reasoning

This paper uses a short dialogue between a determinist and a free-will advocate as a basis for exploring some of the elements of circular reasoning which have for centuries kept alive one of the classical debates of philosophy, the freedom-versus-determinism debate. The chronic circularity which infests both sides of the debate arises from a procedural asymmetry in the argument, which in turn is produced by the different metaphysical commitments of the debaters.     

Why worry about theory‐dependence? Circularity,minimal empiricality and reliability

It is a widely shared view among philosophers of science that the theory‐dependence (or theory‐ladenness) of observations is worrying, because it can bias empirical tests in favour of the tested theories. These doubts are taken to be dispelled if an observation is influenced by a theory independent of the tested theory and thus circularity is avoided, while (partially) circular tests are taken to require special attention. Contrary to this consensus, it is argued that the epistemic value of theory‐dependent tests has nothing to do with the circularity or non‐circularity of the test, but is instead based on the minimal empiricality and reliability of observations. Since theory‐dependence does not in general prevent observations fulfilling these requirements, it should not be regarded as a phenomenon that is basically detrimental, but as neutral with respect to successful scientific knowledge gathering.     

SOSA ON EPISTEMIC CIRCULARITY AND REFLECTIVE KNOWLEDGE

Abstract: Ernest Sosa has done important work on epistemic circularity, epistemic virtue, and reflective knowledge. He holds that epistemic circularity need not be vicious and need not prevent us from knowing that our ways of forming beliefs are reliable. In this article, I briefly explore Sosa's defense of this view and raise some questions about what is required for reflective knowledge.     

Begging the question,circularity and epistemic propriety

In this paper we shall try to understand what it is to beg the question, and since begging the question is generally believed to be linked with circularity, we shall also explore this relationship. Finally, we shall consider whether certain forms of valid argument can go through smoothly in anepistemio context without begging the question. We shall consider, especially, the claims of the disjunctive syllogism in this regard.     

Memory,Quasi-memory,and Pseudo-quasi-memory

Bishop Butler objected to Locke's theory of personal identity on the grounds that memory presupposes personal identity. Most of those sympathetic with Locke's account have accepted Butler's criticism, and have sought to devise a theory of personal identity in the spirit of Locke's that avoids Butler's circularity objection. John McDowell has argued that even the more recent accounts of personal identity are vulnerable to the kind of objection Butler raised against Locke's own account. I criticize McDowell's stance, drawing on a distinction introduced by Annalisa Coliva between two types of immunity to error through misidentification.     

Circularities in the Analysis of Counterfactuals

Expanding on a discussion by Hansson, this paper treats of Goodman's and Lewis' accounts of counterfactual conditionals, comparing the senses in which these theories may be accused of circularity. While I do maintain that in this respect Lewis has an edge over Goodman, the paper's aim is not so much to reach a firm conclusion as to disentangle some previously conflated aspects of the issue. It is also suggested that the importance of avoiding circularity may vary depending on the philosophical purpose of one's analysis. This revised version was published online in August 2006 with corrections to the Cover Date.     

What inductive explanations could not be

Marc Lange argues that proofs by mathematical induction are generally not explanatory because inductive explanation is irreparably circular. He supports this circularity claim by presenting two putative inductive explanantia that are one another’s explananda. On pain of circularity, at most one of this pair may be a true explanation. But because there are no relevant differences between the two explanantia on offer, neither has the explanatory high ground. Thus, neither is an explanation. I argue that there is no important asymmetry between the two cases because they are two presentations of the same explanation. The circularity argument requires a problematic notion of identity of proofs. I argue for a criterion of proof individuation that identifies the two proofs Lange offers. This criterion can be expressed in two equivalent ways: one uses the language of homotopy type theory, and the second assigns algebraic representatives to proofs. Though I will concentrate on one example, a criterion of proof identity has much broader consequences: any investigation into mathematical practice must make use of some proof-individuation principle.     

Pritchard on Virtue Epistemology

Abstract

Peter Godfrey-Smith and Nicholas Shea have argued that standard versions of teleosemantics render explanations of successful behavior by appealing to true beliefs circular and, consequently, non-explanatory. As an alternative, Shea has recently suggested an original teleosemantic account (that he calls ‘Infotel-semantics’), which is supposed to be immune to the problem of circularity. The paper argues that the standard version of teleosemantics has a satisfactory reply to the circularity objection and that, in any case, Infotel-semantics is not better off than standard teleosemantics.     

Justification-affording Circular Arguments

An argument whose conclusion C isessential evidence for one of its premises canprovide its target audience with justificationfor believing C. This is possible becausewe can enhance our justification for believinga proposition C by integrating it into anexplanatory network of beliefs for which C itself provides essential evidence. I arguefor this in light of relevant features ofdoxastic circularity, epistemic circularity,and explanatory inferences. Finally, I confirmmy argument with an example and respond toobjections.     

Reliance,Trust, and Belief

Abstract

An adequate theory of the nature of belief should help us explain the most obvious features of belief as we find it. Among these features are: guiding action and reasoning non-inferentially; varying in strength in ways that are spontaneously experience-sensitive; ‘aiming at truth’ in some sense and being evaluable in terms of correctness and warrant; possessing inertia across time and constancy across contexts; sustaining expectations in a manner mediated by propositional content; shaping the formation and execution of plans; generalizing spontaneously projectively; and being independent of the will and resisting instrumentalization. Using the method of ‘creature construction’, I attempt to show how we can build an attitude with these features step-by-step from simpler components, thereby avoiding the problems of regress or circularity affecting a number of influential accounts of belief.
