Grice’s Razor is a methodological principle that many philosophers and linguists have used to help justify pragmatic explanations of linguistic phenomena over semantic explanations. A number of authors in the debate over contextualism argue that an invariant semantics together with Grice’s (1975) conversational principles can account for the contextual variability of knowledge claims. I show here that the defense of Grice’s Razor found in these “Gricean invariantists,” and its use against epistemic contextualism, display all the (...) problems pointed out earlier in Davis (1998). The everyday variation in acceptable knowledge claims is better explained in terms of implicature than indexicality, but general conversational principles shed little light on whether ‘know’ is used hyperbolically, meiotically, or loosely in a context, although this issue is crucial in deciding what if anything ‘S knows p’ implicates. I present reasons favoring an account of the representative bank case in terms of loose use, making clear how they differ from Grice’s Razor. (shrink)

Grice’s Razor is a principle of parsimony which states a preference for linguistic explanations in terms of conversational implicature, to explanations in terms of semantic context-dependence. Here I propose a Gricean theory of knowledge attributions, and contend on the basis of Grice’s Razor that it is superior to contextualism about ‘knows’.

According to the principle Grice calls 'Modified Occam's Razor' (MOR), 'Senses are not to be multiplied beyond necessity'. More carefully, MOR says that if there are distinct ways in which an expression is regularly used, then, all other things being equal, we should favour the view that the expression is unambiguous and that certain uses of it can be explained in pragmatic terms. In this paper I argue that MOR cannot have the central role that is typically assigned to (...) it by those who deploy it. More specifically, I argue that potential justifications of the epistemic import of parsimony in semantic theorizing are problematic, and that even if MOR could be justified, it has a redundant role to play in adjudicating the debate between the ambiguity-theorist and the proponent of the pragmatic approach.

Advocates of linguistic pragmatics often appeal to a principle which Paul Grice called Modified Occam's Razor: ‘Senses are not to be multiplied beyond necessity’. Superficially, Grice's principle seems a routine application of the principle of parsimony (‘Entities are not to be multiplied beyond necessity’). But parsimony arguments, though common in science, are notoriously problematic, and their use by Griceans faces numerous objections. This paper argues that Modified Occam's Razor makes considerably more sense in light of certain assumptions about (...) the processes involved in language acquisition, and it describes recent empirical findings that bear these assumptions out. The resulting account solves several difficulties that otherwise confront Grice's principle, and it draws attention to problematic assumptions involved in using parsimony to argue for pragmatic accounts of linguistic phenomena.

According to Grice's “Modified Occam's Razor”, in case of uncertainty between the implicature account and the polysemy account of word uses it is parsimonious to opt for the former. However, it is widely agreed that uses can be partially conventionalised by repetition. This fact, I argue, raises a serious problem for MOR as a methodological principle, but also for the substantial notion of implicature in lexical pragmatics. In order to overcome these problems, I propose to reinterpret implicatures in terms (...) of implicature-like effects delivered by non-inferential processes. (shrink)

The works of Paul Grice collected in this volume present his metaphysical defence of value, and represent a modern attempt to provide a metaphysical foundation for value.

The works of Paul Grice collected in this volume present his metaphysical defense of value, and represent a modern attempt to provide a metaphysical foundation for value. Value judgments are viewed as objective; value is part of the world we live in, but nonetheless is constructed by us. We inherit, or seem to inherit, the Aristotelian world in which objects and creatures are characterized in terms of what they are supposed to do. We are thereby enabled to evaluate by reference (...) to function and finality. The most striking part of Grice's position, however, is his contention that the legitimacy of such evaluations rests ultimately on an argument for absolute value. (shrink)

In 1241/4 the theology masters at the university at Paris with their chancellor, Odo of Chateauroux, mandated by their bishop, William of Auvergne, met to condemn ten propositions against theological truth. This book represents the first comprehensive examination of what hitherto has been a largely ignored instrument in a crucial period of the university's early maturation. However, the book's ambition goes wider than this. The condemnation provides a window through which to view the wider doctrinal, intellectual, institutional and historical developments (...) within the emerging university. These include the advent of the Dominicans and Franciscans at the university; and the developing focus of Paris theologians on using their learning for preaching at a time of a rapid and sometimes divergent development of doctrine and concerns over the newly-translated Aristotelian and associated Arab and Jewish works, heresy, the Greek Church and the Jews. The book compares the condemnation's ten articles with the major statement of Catholic principles in the first canon of the Fourth Lateran Council, 1215, and assesses what conclusions can be drawn from their apparent correlation.

Invertebrate genetic models with their tractable neuromuscular systems are effective vehicles for the study of human nerve and muscle disorders. This is exemplified by insights made into spinal muscular atrophy (SMA) using the fruit fly Drosophila melanogaster and the nematode worm Caenorhabditis elegans. For speed and economy, these invertebrates offer convenient, whole‐organism platforms for genetic screening as well as RNA interference (RNAi) and chemical library screens, permitting the rapid testing of hypotheses related to disease mechanisms and the exploration of new (...) therapeutic routes and drug candidates. Here, we discuss recent developments encompassing synaptic physiology, RNA processing, and screening of compound and genome‐scale RNAi libraries, showcasing the importance of invertebrate SMA models.Editor's suggested further reading in BioEssays: SMN and Gemins: ‘We are family’... or are we?

This is a jubilant and rewarding collection of Winterson scholarship--a superb group of essays from a host of fine authors.

Berg seeks to defend the theory that the meaning of a proper name in a belief report is its reference against Frege’s puzzle by hypothesizing that when substituting coreferential names in belief reports results in reports that seem to have different truth values, the appearance is due to the fact that the reports have different metalinguistic implicatures. I review evidence that implicatures cannot be calculated in the way Grice or Berg imagine, and give reasons to believe that belief reports do (...) not have the implicatures Berg attributes to them. I also argue that even if belief reports did have such implicatures, they would not explain why the belief reports in Frege’s puzzle seem to have different truth values. I point out that Berg has no reason to believe that Lois Lane believes Clark Kent is a reporter and Lois Lane believes Superman is a reporter are both true rather than both false, and that Leibniz’s Law cannot be used to defend substitutivity in belief reports because belief reports are not relational in the requisite way. Finally, I observe that some of the linguistic data Berg uses to argue for substitutivity in belief reports concerns the transparent interpretation of belief reports, whereas Frege’s puzzle concerns the opaque interpretation.

In this paper I develop and present a unified account of information, misinformation, and disinformation and their interconnections. The unified account is rooted in Paul Grice’s notions of natural and non-natural meaning (in: Grice (ed) Studies in the way of words. Harvard University Press, Cambridge, pp 213–223, 1957) and a corresponding distinction between natural and non-natural information (Scarantino and Piccinini in Metaphilosophy 41(3):313–330, 2010). I argue that we can specify at least three specific kinds of non-natural information. Thus, as (...) varieties of non-natural information there is intentionally non-misleading information, unintentionally misleading information—i.e. misinformation—and intentionally misleading information—i.e. disinformation. By shifting the focus from the truth-values of content to the intention/intentionality and misleadingness/non-misleadingness of that content I obtain a unified account that makes room for the potential misleadingness of true content (true disinformation), the potential non-misleadingness of false content (irony), and everything in between.

A más de cien años de su nacimiento y casi treinta de su muerte, Paul Grice sigue siendo uno de los filósofos más citados, discutidos e incomprendidos del siglo xx. Innovador, desafiante e inconforme intelectualmente, parece haber llevado a cabo uno de los anhelos más profundos de la filosofía oxoniense del lenguaje ordinario: transformar la reflexión sobre el lenguaje en una reflexión sobre la acción humana. El libro argumenta a favor de esta tesis señalando cómo algunos problemas específicos de la (...) filosofía del lenguaje de Grice sólo pueden ser tratados en el contexto de sus reflexiones más maduras sobre acción, racionalidad y valor. Defiende también la posición de que muchas explicaciones de significado son lógicamente análogas a las explicaciones de la acción. Pero la evaluación de la acción en términos de las razones involucra al menos dos tipos de restricciones racionales: aquellas internas al hablante (lo que resulta racional para él) y otras externas (lo que el hablante debe hacer desde el punto de vista de los demás). Con su celebrado análisis del significado del hablante, Grice enfatiza rasgos del primer tipo; con su famosa teoría de la conversación, identifica rasgos del segundo. Y ambos tipos de restricciones solo tienen sentido si se reconoce que el significado de una palabra o de una conducta no es una cosa ni una entidad mental sino la conformidad del símbolo o la acción con un criterio normativo. La conclusión general de Grice resuena más allá de sus contribuciones precursoras en filosofía del lenguaje y permite articular una posición metafísica. En un mundo sin seres capaces de evaluar, de dar y reconocer valor, la pregunta por el significado carecería de objeto. (shrink)

I offer two potential diagnoses of the behavioral norms governing post‐truth politics by comparing the view of language, communication, and truth‐telling put forward by David Lewis (extended by game theorists), and John Searle. My first goal is to specify the different ways in which Lewis, and game theorists more generally, in contrast to Searle (in the company of Paul Grice and Jurgen Habermas), go about explaining the normativity of truthfulness within a linguistic community. The main difference is that for Lewis (...) and game theorists, “truthful” signaling follows from an align- ment of interests, and deception follows from mixed motives leading to the calculation that sending false information is better for oneself. Following in the Enlightenment tradition, Searle argues that practical reasoning, which involves mastery of at least one language, requires that actors intend to communicate. This intention includes constraining the content of statements to uphold veracity conditions. After distinguishing between these two accounts, I will artic- ulate the implications for explaining, and even informing actions, constitutive of post‐truth politics. I argue that the strategic view of communication is suffi- cient neither to model everyday conversation nor to reflect a public sphere useful for democratic govern- ment. Both the pedagogy of strategic communication as cheap talk, and its concordance with new digital information technologies, challenge norms of truthful- ness that underlie modern institutions essential to an effective public sphere.

In the Bṛhadāraṇyaka Upaniṣad, one of the principal Upaniṣads, we find a venerable and famous story where the god Prajāpati separately instructs three groups of people (gods, humans, and demons) simply by uttering the syllable “Da.” In this paper, our concern is not with ethics but theories of meaning and interpretation: How can all divergent interpretations of a single expression be correct, and, indeed, endorsed by the speaker? As an exercise in cross-cultural philosophical reflection, we consider some of the leading (...) modern theories of meaning—those of Grice, Quine, and Davidson—in order to see if the Upaniṣadic story receives a natural home in any of them. We conclude that the story is best understood through Grice’s theory of meaning rather than Quine’s or Davidson’s. (shrink)

The notion of common ground is important for the production of referring expressions: In order for a referring expression to be felicitous, it has to be based on shared information. But determining what information is shared and what information is privileged may require gathering information from multiple sources, and constantly coordinating and updating them, which might be computationally too intensive to affect the earliest moments of production. Previous work has found that speakers produce overinformative referring expressions, which include privileged names, (...) violating Grice’s Maxims, and concluded that this is because they do not mark the distinction between shared and privileged information. We demonstrate that speakers are in fact quite effective in marking this distinction in the form of their utterances. Nonetheless, under certain circumstances, speakers choose to overspecify privileged names. (shrink)

Grice's Quantity maxims have been widely misinterpreted as enjoining a speaker to make the strongest claim that she can, while respecting the other conversational maxims. Although many writers on the topic of conversational implicature interpret the Quantity maxims as enjoining such volubility, so construed the Quantity maxims are unreasonable norms for conversation. Appreciating this calls for attending more closely to the notion of what a conversation requires. When we do so, we see that eschewing an injunction to maximal informativeness need (...) not deprive us of any ability to predict or explain genuine cases of implicature. Crucial to this explanation is an appreciation of how what a conversation, or a given stage of a conversation, requires, depends upon what kind of conversation is taking place. I close with an outline of this dependence relation that distinguishes among three importantly distinct types of conversation. (shrink)

Ockham's razor, the principle of parsimony, states that simpler theories are better than theories that are more complex. It has a history dating back to Aristotle and it plays an important role in current physics, biology, and psychology. The razor also gets used outside of science - in everyday life and in philosophy. This book evaluates the principle and discusses its many applications. Fascinating examples from different domains provide a rich basis for contemplating the principle's promises and perils. (...) It is obvious that simpler theories are beautiful and easy to understand; the hard problem is to figure out why the simplicity of a theory should be relevant to saying what the world is like. In this book, the ABCs of probability theory are succinctly developed and put to work to describe two 'parsimony paradigms' within which this problem can be solved. (shrink)

Sure to be popular in the hipper precincts of Brooklyn, this eccentric Victorian volume makes a strong case for the universal wearing of beards. Reminding us that since ancient times the beard has been an essential symbol of manly distinction, Thomas S. Gowing presents a moral case for eschewing the bitter bite of the razor. He contrasts the vigor and daring of the bearded—say, lumberjacks and Lincoln—with the undeniable effeminacy of the shaven. Manliness is found in the follicles, and (...) the modern man should not forget that “ladies, by their very nature, like everything manly,” and cannot fail to be charmed by a fine “flow of curling comeliness.” Even old men can hold on to their vitality via their beards: “The Beard keeps gradually covering, varying and beautifying, and imparts new graces even to decay, by highlighting all that is still pleasing, veiling all that is repulsive.” A truly strange polemic, _The Philosophy of Beards_ is as charming as it is bizarre, the perfect gift for the manly man in your life.

Such a thesis is counter to prevailing trends among contemporary philosophers. All that is about to be maintained is that facts may be regarded as entities, i.e. that it is legitimate and tenable so to regard them; this is much less than saying that they must be so regarded, and that anyone who declined to make use of the category of facts would be mistaken. Yet even so weak a thesis will be viewed askance by many; those who concede its (...) meaningfulness and logical possibility will still, a large proportion of them, dismiss it on other grounds-particularly on the ground of superfluity. And precisely one of the reasons why we have selected this particular thesis for defense, is as an occasion to examine the weight and force of Ockham's Razor. (shrink)

We are all acquainted with persons who seem to have a talent for making things over-complex, persons who invent exceedingly devious explanations for what can be simply explained. Such individuals strike us as hardened violators of Occam's Razor: Entities are not to be multiplied unnecessarily. We shall say briefly that such persons goropise.

Approaches to model evaluation in terms of Occam's razor or principles of parsimony cannot avoid judgements about the relative importance of aspects of the models. Assumptions about “core processing” are usually considered more important than those related to decision components, but when the decision is related to a central feature of the processing, it becomes extremely difficult to tease apart the influences of core and decision components and to draw sensible conclusions about underlying architecture. It is preferable, where possible, (...) to use experimental procedures that avoid the necessity for subject decisions related to critical aspects of the underlying process. (shrink)

I recall reading a critical notice of Grices’ Studies in the Way of Words, in which the author remarked that while Grice’s analysis of speaker meaning is the subject of considerable controversy, Grice’s account of conversational implicature is, “…money in the philosophical bank.” This assessment was optimistic at best: Grice’s remarks on implicature offer a program not a theory, and in relation to the amount of discussion it has received in philosophy and allied disciplines such as linguistics (...) and psycholinguistics, rather little work has been done in cashing the approach out as a theory. At the same time, many objections to Grice have been raised and not many adequately fielded. Davis’ is the first book-length treatment by a philosopher of the phenomenon of implicature, and we could not have hoped for a more clearheaded and conscientious author willing to subject the Gricean treatment of implicature to rigorous and impartial scrutiny.

Two conceptions of language have dominated philosophical reflection over the last century on the nature of language and linguistic understanding. The first is the calculus conception, advanced in various forms by Frege, Russell, the early Wittgenstein, Carnap, Dummett and Davidson. The second is the anthropological conception of language advanced in various forms by the later Wittgenstein, Strawson, and Grice. The purpose of the paper is to compare and contrast the two conceptions. The calculus conception assigns priority to the notions of (...) truth and truth-condition, and to the assertoric mode. The anthropological conception assigns priority to use, meaning and explanations of meaning, and is indifferent to mode. The disagreements between the two conceptions are explored, and the further consequences of each conception are described. (shrink)

If I had to say what the single most important contribution Wittgenstein made to philosophy was, it would be to have revived the animal in us: the animal that is there in every fiber of our human being, and therefore also in our thinking and reasoning. This means, his pushing us to realize that we are animals not only genealogically, but as evolved human beings—whether neonate, or language-possessing, civilized, law-abiding, fully fledged adults. Constitutionally, and in everything we do, still fundamentally (...) animals. (shrink)

We begin by presenting William of Ockham's various formulations of his principle of parsimony, Ockham's Razor. We then define a reaction mechanism and tell a personal story of how Ockham's Razor entered the study of one such mechanism. A small history of methodologies related to Ockham's Razor, least action and least motion, follows. This is all done in the context of the chemical (and scientific) community's almost unthinking acceptance of the principle as heuristically valuable. Which is not (...) matched, to put it mildly, by current philosophical attitudes toward Ockham's Razor. What ensues is a dialogue, pro and con. We first present a context for questioning, within chemistry, the fundamental assumption that underlies Ockham's Razor, namely that the world is simple. Then we argue that in more than one pragmatic way the Razor proves useful, without at all assuming a simple world. Ockham's Razor is an instruction in an operating manual, not a world view. Continuing the argument, we look at the multiplicity and continuity of concerted reaction mechanisms, and at principal component and Bayesian analysis (two ways in which Ockham's Razor is embedded into modern statistics). The dangers to the chemical imagination from a rigid adherence to an Ockham's Razor perspective, and the benefits of the use of this venerable and practical principle are given, we hope, their due.

The pragmatics underlying Paul Grice’s analysis of utterance-meaning provide a powerful framework for investigating the commitments arguers undertake. Unfortunately, the complexity of Grice’s analysis has frustrated appropriate reliance on this important facet of his work. By explicating Cicero’s use of apostrophe in his famous “First Catilinarian” this essay attempts to show that a full complex of reflexive gricean speaker intentions in essentially to seriously saying and meaning something.

“Never attribute to malice that which is adequately explained by stupidity”—so says Hanlon’s Razor. This principle is designed to curb the human tendency toward explaining other people’s behavior by moralizing it. We ask whether Hanlon’s Razor is good or bad advice. After offering a nuanced interpretation of the principle, we critically evaluate two strategies purporting to show it is good advice. Our discussion highlights important, unsettled questions about an idea that has the potential to infuse greater humility and (...) civility into discourse and debate. (shrink)

Detecting quality in large unstructured datasets requires capacities far beyond the limits of human perception and communicability and, as a result, there is an emerging trend towards increasingly complex analytic solutions in data science to cope with this problem. This new trend towards analytic complexity represents a severe challenge for the principle of parsimony (Occam’s razor) in science. This review article combines insight from various domains such as physics, computational science, data engineering, and cognitive science to review the specific (...) properties of big data. Problems for detecting data quality without losing the principle of parsimony are then highlighted on the basis of specific examples. Computational building block approaches for data clustering can help to deal with large unstructured datasets in minimized computation time, and meaning can be extracted rapidly from large sets of unstructured image or video data parsimoniously through relatively simple unsupervised machine learning algorithms. Why we still massively lack in expertise for exploiting big data wisely to extract relevant information for specific tasks, recognize patterns and generate new information, or simply store and further process large amounts of sensor data is then reviewed, and examples illustrating why we need subjective views and pragmatic methods to analyze big data contents are brought forward. The review concludes on how cultural differences between East and West are likely to affect the course of big data analytics, and the development of increasingly autonomous artificial intelligence (AI) aimed at coping with the big data deluge in the near future.

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham responds to (...) this dilemma, his razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

In this paper we show that the application of Occam’s razor to the theory of causal Bayes nets gives us a neat definition of direct causation. In particular we show that Occam’s razor implies Woodward’s (2003) definition of direct causation, provided suitable intervention variables exist and the causal Markov condition (CMC) is satisfied. We also show how Occam’s razor can account for direct causal relationships Woodward style when only stochastic intervention variables are available.

_ Source: _Page Count 29 Underdetermination arguments for skepticism maintain that our common sense view of the external world is no better, evidentially speaking, than some skeptical competitors. An important and well-known response by dogmatists, those who believe our commonsense view is justified, appeals to abduction or inference to the best explanation. The predominant version of this strategy, going back at least to Locke, invokes Occam’s razor: dogmatists claim the common sense view is simpler than any of its skeptical (...) alternatives and so has more to recommend it, evidentially speaking. This dispute has overshadowed another possible view: skeptical dogmatism. Skeptical dogmatists hold that we are justified in believing that the common sense view is probably false. I argue that skeptical dogmatism presents some interesting complications to the dialectic between the dogmatist and the skeptic. On the one hand, even if the dogmatist’s use of Occam’s razor is sufficient to rebut skepticism, in itself it is not sufficient to refute skeptical dogmatism. On the other hand, skeptics themselves, ironically, must, given the assumptions of the paper, appeal to something like Occam’s razor in order to avoid capitulating to skeptical dogmatism. (shrink)

The notion of de re truth (Conte, 2016) is put to work in this paper (§ 1). It introduces us to a confrontation between a metaphysics of desertic landscapes, as presented in a stunning poem by Achille Varzi and Claudio Calosi, The Tribulations of Philosophye (§ 2), and an ontology of the lifeworld, as a long-term project based on the key concept of bonds (De Monticelli, 2018). The rich and structured objects of the everyday world are infinite sources of information (...) and cognitive adventure (§§ 3, 3.1., 3.2). Or so I will claim against Varzi’s skepticism about ordinary language, common sense, and ontological realism (§ 4). Far from encouraging our minds to stick to concrete individual things, Ockham’s Razor has been the murder weapon in the dismission of concreteness and the sensible world from the intellectual horizon of Modernity (§§ 5, 6). The “Unitarian Tradition” is a half-playful denomination of a quite real, albeit ignored, alternative theory of individuality (and hence concreteness), brilliantly represented by Boethius, Duns Scotus, and Leibniz. Classic phenomenology quite independently revived it and brought it up to modern analytic standards of rigor and formality (§ 7). (shrink)

Occam's razor—the idea that all else being equal, we should pick the simpler hypothesis—plays a prominent role in ordinary and scientific inference. But why are simpler hypotheses better? One attractive hypothesis known as Bayesian Occam's razor is that more complex hypotheses tend to be more flexible—they can accommodate a wider range of possible data—and that flexibility is automatically penalized by Bayesian inference. In two experiments, we provide evidence that people's intuitive probabilistic and explanatory judgments follow the prescriptions of (...) BOR. In particular, people's judgments are consistent with the two most distinctive characteristics of BOR: They penalize hypotheses as a function not only of their numbers of free parameters but also as a function of the size of the parameter space, and they penalize those hypotheses even when their parameters can be “tuned” to fit the data better than comparatively simpler hypotheses.
