The standard definition of “argument” is satisfied by any series of statements in which one (of the statements) is marked as the conclusion of the others. This leads to the counter-intuitive result that “I like cookies, therefore, all swans are white” is an argument, since “therefore” marks “all swans are white” as the conclusion of “I like cookies”. This objection is often disregarded by stating that, although the previous sequence is an argument, it fails to be (...) a good one. However, when we compare our previous argument with a definitely bad argument like “this swan is white, therefore, all swans are white”, we see that there is an important difference between them. Whereas the former fails to fulfil our intuition of what an argument is, the latter does qualify as an argument, but as a bad one. In this talk, I will sketch a definition that better captures this feature of our intuition of what an argument is in three steps. Following Díez and Moulines (1999), I first reduce inductive validity to deductive validity through what we may call the method of deductivisation. Second, through epistemic predicates (cf. Thompson 2002), I introduce a broader concept of validity that accounts not only for deductive and inductive validity, but also for a weaker type of validity that may be called pseudo-validity. I show that these pseudo-valid arguments can also be deductivised with the help of the above-mentioned epistemic predicates. Finally, I re-define the concept of argument as any series of statements that is at least pseudo-valid, which leaves the “cookies argument” outside of this definition. (shrink)

Bettina Schöne-Seifert and Marco Stier present a host of detailed and intriguing arguments to the effect that potentiality arguments have to be viewed as outdated due to developments in stem cell research, in particular the possibility of re-setting the development potential of differentiated cells, such as skin cells. However, their argument leaves them without an explanation of the intuitive difference between skin cells and human beings, which seems to be based on the assumption that a skin cell is merely (...) part of a human organism, while an embryo is at some point a human organism. An appropriately designed concept of the human organism can explain the difference, but also has the potential of re-dividing the argumentative landscape along familiar lines. (shrink)

As Leibniz points out in the Méditation sur la notion commune de la jus tice, justice—defined as charity of the wise and universal benevolence—belongs “to the necessary and eternal truths about the nature of things, as numbers and proportions.” According to the interpretation of Patrick Riley, from this perspective the two manuscripts usually regarded as belonging to the Méditation should be seen as complementary parts of a unitary Platonizing work. According to Riley, the manuscript that now constitutes the first part (...) of the Méditation is concerned with definitions of ethical concepts viewed as “quasi-mathematical, demonstrable ‘eternal verities’”, whereas the manuscript that now constitutes the second part of the Méditation is concerned “with Platonic ‘ascent’, in the manner of Phaedrus and Symposium,” which recommends the transition from mere negative forbearance from harm to doing positive good. In formulating these claims, Riley uses scare quotes to indicate that he uses the terms “eternal verities” and “ascent” in an unusual way that diverges from the views of the historical Plato. According to his interpretation, Leibniz’s modifications of Platonism are restricted to peripheral parts such as the doctrine of the pre-existence of the soul or Pythagorean components such as the doctrine of metempsychosis. Therefore, Riley claims that when Leibniz is talking about knowing eternal truths, what he has in mind is literally the view that we know the same truths as the truths that the gods know and love but do not cause or change.

Wokeism is a doctrina (doctrine) of knowledge, reason and belief within U.S. society, about U.S. society, taught by scholars (doctors) and teachers to their students. Currently there exists three definitions of wokeism in dictionaries. Currently there exists no scholarly peer-reviewed articles in science or philosophy on the theory of wokeism. Interestingly, there does exist 170 articles in various publications talking about wokeism by scholars. Since there is no current definition or subject in philosophy of the subject of wokeism, it (...) is either impossible or intellectually dishonest to have a reasoned argument including the word wokeism by any doctor of philosophy. This paper establishes a scholarly definition of wokeism, as well as possible branches of philosophy to develop understanding of this subject and doctrine. (shrink)

In this paper I argue that philosophers of sport should avoid value-laden definitions of sport; that is, they should avoid building into the definition of sport that they are inherently worthwhile activities. Sports may very well often be worthwhile as a contingent matter, but this should not be taken to be a core feature included in the definition of sport. I start by outlining what I call the ‘legitimacy-conferring’ element of the category ‘sport’. I then argue that we (...) ought not to include such a dimension in our definition of sport, on the grounds that it confuses issues of description with issues of definition: the issue of what sport does with what sport is. Following this, I consider a Wittgensteinian family resemblance approach to defining sport; Kevin Schieman’s argument that sports are necessarily good games; and the oft-cited wide-following and institutional criteria, as arguments for including an evaluative dimension in the definition of sport. I conclude that none succeed, for similar reasons: they either fail to track our common sense intuitions about what does or does not count as a sport; and/or they make it impossible for us to ever describe something a ‘bad’ sport (or instance of sport). Just as a good definition of, say, art, shouldn’t make it impossible for us to describe something as ‘bad art’, I argue that our definition of sport shouldn’t build in a necessarily positive evaluation. I conclude by discussing some of the practical reasons why supporters of activities about which there is currently debate as to their status as sports might want to see those activities included under the sports umbrella, but suggest that this on its own isn’t a good reason for modifying a philosophical definition of sport to include them.

The definition and the assessment of the quality of argumentative texts has become an increasingly crucial issue in education, classroom discourse, and argumentation theory. The different methods developed and used in the literature are all characterized by specific perspectives that fail to capture the complexity of the subject matter, which remains ill-defined and not systematically investigated. This paper addresses this problem by building on the four main dimensions of argument quality resulting from the definition of argument (...) and the literature in classroom discourse: dialogicity, accountability, relevance, and textuality (DART). We use and develop the insights from the literature in education and argumentation by integrating the frameworks that capture both the textual and the argumentative nature of argumentative texts. This theoretical background will be used to propose a method for translating the DART dimensions into specific and clear proxies and evaluation criteria. (shrink)

Since the publication of Hartry Field’s influential paper “Tarski’s Theory of Truth” there has been an ongoing discussion about the philosophical import of Tarski’s definition. Most of the arguments have aimed to play down that import, starting with that of Field himself. He interpreted Tarski as trying to provide a physicalistic reduction of semantic concepts like truth, and concluded that Tarski had partially failed. Robert Stalnaker and Scott Soames claimed then that Field should have obtained a stronger conclusion, namely (...) that Tarski’s failure in his allegedly intended physicalistic reduction was total. From another front, Hilary Putnam argued for an even more sweeping thesis: “[a]s a philosophical account of truth, Tarski’s theory fails as badly as it is possible for an account to fail.” Scott Soames followed suit also on this count, endorsing Putnam’s argument in section iii of the aforementioned paper; and John Etchemendy used a very similar argument to contend that “a Tarskian definition of truth [...] cannot possibly illuminate the semantic properties of the object language.” The paper argues that these contentions are based on several misunderstandings about the nature of a definition like Tarski’s. Regarding the Putnam-Soames-Etchemendy argument, we must apply a distinction Frege found natural to draw—and is natural to draw anyway—between what he called “constructive” definitions, definitions properly so called, which are mere stipulations, and what he described as “analytic” definitions, definitions which aim to make explicit the meaning of a term already in use. Regarding the Field-Soames-Stalnaker criticism, the paper contends that the true aims of a Tarskian truth definition are perfectly well fulfilled without Field’s amendments. (shrink)

Physicalism is incompatible with what is known as the possibility of zombies, that is, the possibility of a world physically like ours, but in which there are no conscious experiences. But it is compatible with what is known as the possibility of ghosts, that is, the possibility of a world which is physically like ours, but in which there are additional nonphysical entities. In this paper we argue that a revision to the traditional definition of physicalism designed to accommodate (...) the possibility of ghosts inadvertently accommodates what is known as the possibility of inverted spectra, that is, the possibility of a world which is physically like ours, but in which colour experience is inverted. This consequence is unwelcome, because it is widely agreed that the possibility of inverted spectra is incompatible with physicalism. We argue for a revised definition of physicalism which resolves this problem. We then use our definition to argue that physicalism is not compatible with what is known as the possibility of blockers, that is, the possibility of a world which is physically like ours, but in which additional nonphysical entities have prevented the existence of conscious experience. This undermines Stephan Leuenberger's attempt to defend physicalism from arguments which purport to establish the possibility of zombies. (shrink)

Why should one think Frege's definition of the ancestral correct? It can be proven to be extensionally correct, but the argument uses arithmetical induction, and that seems to undermine Frege's claim to have justified induction in purely logical terms. I discuss such circularity objections and then offer a new definition of the ancestral intended to be intensionally correct; its extensional correctness then follows without proof. This new definition can be proven equivalent to Frege's without any use (...) of arithmetical induction. This proves, without any use of arithmetical induction, that Frege's definition is extensionally correct and so answers the circularity objections. (shrink)

In this article, the results of conceptualization of the definition of mind as an object of interdisciplinary applied research are described. The purpose of the theoretical analysis is to generate a methodological discourse suitable for a functional understanding of the mind in the context of the problem of natural language processing as one of the components of developments in the field of artificial intelligence. The conceptual discourse was realized with the help of the author's method of structural-ontological analysis, and (...) developed in the mainstream of the system-methodological tradition of the school of G.P. Shchedrovitsky and intended for descriptive research of subject areas of interdisciplinary objects of scientific study. As a result of the structural and ontological analysis of the super-system, the relevant place and role of the directly studied system (mind) are determined, and its primary process and material are localized and structural and functional connections are described. At the basic level, the mind is conceptualized as an energy process unfolding in a spatio-temporal environment and accompanied by archetypal structuring of neural impulses into images. The genesis of the system is separately analyzed by constructing a structural-ontological matrix that reflects the initial stage of the development of the mind. The primary process is concretized with the help of hetero- and homeostatic dichotomy, and also the most significant features of the consistent transformation of the material of the system and its ascent to verbal morphology are described. The structural-ontological comparison of the functioning of the verbal intelligence with the preverbal level has been carried out. The transformation of neural impulses of needs into words, as verbal units fixing semiotic values is analyzed. Structural-ontological connections that determine the reactive and prospective characteristics of the functioning of the system are disclosed. The position of the chronological primacy of "semiotic readiness" for language with respect to the debut of the latter as an information-sign model of the environment is argued. The hypothesis of domination at the initial stage of the development of the mind of exopsychic functions over endopsychic ones is formulated. The theoretical substantiation of the hypothesis of the inevitability of the ontology of language in the functional understanding of the mind is given, corresponding structural and ontological arguments are given, including those based on the ideas about the information relationship between affects and needs, according to the views of P.V. Simonov. The arguments are presented in favor of the non-alternative methodology of A. Turing in studies of artificial intelligence. (shrink)

In this article I examine two mathematical definitions of observational equivalence, one proposed by Charlotte Werndl and based on manifest isomorphism, and the other based on Ornstein and Weiss’s ε-congruence. I argue, for two related reasons, that neither can function as a purely mathematical definition of observational equivalence. First, each definition permits of counterexamples; second, overcoming these counterexamples will introduce non-mathematical premises about the systems in question. Accordingly, the prospects for a broadly applicable and purely mathematical definition (...) of observational equivalence are unpromising. Despite this critique, I suggest that Werndl’s proposals are valuable because they clarify the distinction between provable and unprovable elements in arguments for observational equivalence.

Interpreters have found it exceedingly difficult to understand how Hume could be right in claiming that his two definitions of ‘cause’ are essentially the same. As J. A. Robinson points out, the definitions do not even seem to be extensionally equivalent. Don Garrett offers an influential solution to this interpretative problem, one that attributes to Hume the reliance on an ideal observer. I argue that the theoretical need for an ideal observer stems from an idealized concept of definition, which (...) many interpreters, including Garrett, attribute to Hume. I argue that this idealized concept of definition indeed demands an unlimited or infinite ideal observer. But there is substantial textual evidence indicating that Hume disallows the employment of idealizations in general in the sciences. Thus Hume would reject the idealized concept of definition and its corresponding ideal observer. I then put forward an expert-relative reading of Hume’s definitions of ‘cause’, which also renders both definitions extensionally equivalent. On the expert-relative reading, the meaning of ‘cause’ changes with better observations and experiments, but it also allows Humean definitions to play important roles within our normative practices. Finally, I consider and reject Henry Allison’s argument that idealized definitions and their corresponding infinite minds are necessary for expert reflection on the limitations of current science.

One of the most pivotal yet under-examined moments in Spinoza's Theological-Political Treatise is his attempt to define the notion of 'faith'. In this paper, I unpack Spinoza's understanding of his definition and its significance within the broader argument of the Treatise by carefully analyzing the relationship between the definition's terminology and logical structure. I specifically examine the connection Spinoza draws between faith and obedience, arguing that according to Spinoza's definition, conceiving of obedience implies conceiving of faith, (...) and not the other way around (as many commentators have claimed). I explore the implications of this entailment for interpreting the nature and function of Spinoza's 'dogmas of universal faith'. Spinoza claims that the definition faith ultimately grounds his main argument in the Treatise, which makes the case for a radical separation between 'faith' and 'philosophy'. One of my goals in the paper is to bring out in higher resolution how the definition underwrites this argument, and what it ultimately means. (shrink)

Some of our beliefs are institutional; that is, beliefs whose content is to a large extent shaped by institutions, such as beliefs about intellectual property, trade policy, or traffic rules. In this chapter, we propose a novel account of institutional beliefs, as we call them. In particular, we argue that institutional beliefs are primarily attributable to social entities, such as groups or collectives, and only secondarily to individual agents. This is because institutional beliefs respond to specific problems that, in principle, (...) only collectives face. However, existing methodology in behavioural science primarily relies on eliciting beliefs through individual choice data, which presents challenges for empirically modelling our proposed concept of institutional beliefs. To address this challenge, we propose to speak of institutional beliefs attributable to individual agents as ‘qua beliefs’. That is, institutional beliefs attributable to individual agents acting qua members of certain institutionally shaped groups. Within this framework, individuals’ qua actions occur in a shared realm of problems that can only be addressed through collective efforts. The relationship between individuals and their groups can be rendered tractable under formalised conditions. Under these conditions, choice data collected from individuals need not obstruct the elicitation of institutional beliefs for empirical study at both the collective and the individual level. We refer to these conditions as “IS conditions”, which are developed based on the synthesis between an interpretationist understanding of mental states and standard models of revealed preference theory as used in experimental economics. For an illustration of how this approach can be operationalised experimentally, we direct our readers to chapter 10 of this volume, where an experimental study applied our account of institutional beliefs.

In this paper we present an analysis of persuasive definition based on argumentation schemes. Using the medieval notion of differentia and the traditional approach to topics, we explain the persuasiveness of emotive terms in persuasive definitions by applying the argumentation schemes for argument from classification and argument from values. Persuasive definitions, we hold, are persuasive because their goal is to modify the emotive meaning denotation of a persuasive term in a way that contains an implicit argument (...) from values. However, our theory is different from Stevenson’s, a positivistic view that sees emotive meaning as subjective, and defines it as a behavioral effect. Our proposal is to treat the persuasiveness produced by the use of emotive words and persuasive definitions as due to implicit arguments that an interlocutor may not be aware of. We use congruence theory to provide the linguistic framework for connecting a term with the function it is supposed to play in a text. Our account allows us to distinguish between conflicts of values and conflicts of classifications. (shrink)

In this paper the author reviews the most debated theories of art in contemporary aesthetics and offers a new, intentional-attributive definition of art. He begins by expanding on Weitz’s theory, after which he presents arguments that refute Weitz's claim that it is logically impossible to define art. The author then examines the institutional, the historical, and the aesthetic definitions of art and shows that all of these have weaknesses and none stands up completely to criticism. Taking into consideration the (...) shortcomings of the examined definitions, he suggests his own definition of art: for all x, x is an artwork if the author of x mainly intended to reveal such properties of x, the perception of which would evoke experiences, containing ends in themselves.

The orientation of this paper is that there is no special science of "business ethics" any more than there is one of "medical ethics" or "legal ethics". While there may be issues that arise in medicine or law that require special treatment, the ways of relating to such issues are derived from a basic ethical stance. Once one has evolved such an ethical stance and thus has incorporated a fundamental mode of relating to her or his fellow human beings, the (...) "how" to deal with various ethical "issues" will follow as a natural consequence of one's ethical stance or modality. It is not necessary, in the formation of one's fundamental ethical stance to know if one is a utilitarian or a deontologist. It is doubtful whether Buddha knew what kind of ethics he was practising. If one conceives of ethics as something extrinsic to various disciplines and attempts to first practise a discipline and then to apply ethics to modify the results of that discipline it is entirely possible that conflicts will result between what is perceived of as the proper pursuit of that discipline and the ethical considerations. The argument of this paper is that it is more efficacious (in addition to being more true) to take ethical considerations into account in the construction of the definition of the discipline. This paper is devoted to showing that business and ethics are not two different and competing fields of interest (thus requiring a discipline of business ethics to be grafted onto the study of business enterprise), but that ethical concerns are part and parcel of the very concept of a business enterprise and the internal operation of a business organization.

In this article, I use Edmund Gettier’s Ten Coins hypothetical scenario to illustrate some reasoning errors in the use of definite descriptions. The Gettier problem, central as it is to modern epistemology, is first and foremost an argument, which Gettier (Analysis 23(6):121–123, 1963) constructs to prove a contrary conclusion to a widely held view in epistemology. Whereas the epistemological claims in the case have been extensively analysed conceptually, the strategies and tools from other philosophical disciplines such as analytic philosophy (...) of language, logic and argumentation that Gettier deploys in the case have scarcely received any attention. This work abstracts from the epistemological content and examines Gettier’s handling of the definite description involved, and how that affects the cogency of his argument. (shrink)

Philosophers and logicians talk of arguments for conclusions. In a recent paper, Jeffrey Goodman identifies a common way of thinking about what an argument is. I propose a definition that is quite different to this common way. I also make two objections to Goodman’s proposed definition.

One of the most challenging issues in medical ethics is a permission or prohibition of euthanasia. Is a patient with an incurable disease who has lots of pain permitted to kill oneself or ask others to do that? The main reason advanced by the opponents is the absolute prohibition of murder. Accordingly, the meaning of murder plays a key role in determining the moral judgment of euthanasia. The aim of this paper is to confirm the role of intention in moral (...) judgment of euthanasia and eliminate the name of unjust murder from voluntary euthanasia. The Intention of an agent determines the name of the act and whether it is right or wrong. An important point that dose not taken into account in the definitions of murder, killing as well as their ethical judgment is considering the attributes of being unjust and forcible. Killing a human being is neither intrinsically good nor bad, but its ethical judgment depends on the way that happens, i.e. just or unjust. Every killing is neither bad nor unethical except unjust one which is both bad and unethical. The attribute of “unjust” has been mentioned in the definition of murder in Islamic jurisprudence, law, traditions, and Quran. Owing to this argument, on one hand, it is true to state that voluntary euthanasia is not unjust and forcible murder (the test of correct negation), and on the other hand, it is not true to say that voluntary euthanasia is unjust and forcible murder (the test of incorrect predication). It can be concluded that voluntary euthanasia is an independent title other than unjust murder and does not have its judgment. (shrink)

When are we, in fact, arguing? Even one and the same author may offer more than one definition of what he understands by argumentation: this is partly because the problem of argumentation is not confined to a single area of knowledge or of practical life. Definitions of argumentation are as varied as the different positions taken on the question of what exactly we do when we argue. Be that as it may, we are struck by the fact that the (...) problem of argumentation (above all in its application to hypothetic-inductive methods) has not been analysed as a problem linked to interpretation.

The aim of the paper is to develop general criteria of argumentative validity and adequacy for probabilistic arguments on the basis of the epistemological approach to argumentation. In this approach, as in most other approaches to argumentation, proabilistic arguments have been neglected somewhat. Nonetheless, criteria for several special types of probabilistic arguments have been developed, in particular by Richard Feldman and Christoph Lumer. In the first part (sects. 2-5) the epistemological basis of probabilistic arguments is discussed. With regard to the (...) philosophical interpretation of probabilities a new subjectivist, epistemic interpretation is proposed, which identifies probabilities with tendencies of evidence (sect. 2). After drawing the conclusions of this interpretation with respect to the syntactic features of the probability concept, e.g. one variable referring to the data base (sect. 3), the justification of basic probabilities (priors) by judgements of relative frequency (sect. 4) and the justification of derivative probabilities by means of the probability calculus are explained (sect. 5). The core of the paper is the definition of '(argumentatively) valid derivative probabilistic arguments', which provides exact conditions for epistemically good probabilistic arguments, together with conditions for the adequate use of such arguments for the aim of rationally convincing an addressee (sect. 6). Finally, some measures for improving the applicability of probabilistic reasoning are proposed (sect. 7). (shrink)

This paper aims to reconstruct the politico-philosophical content of the Ancient Wenzi, according to three interrelated questions: How does the text communicate its views to the reader? What are its main ideas? When and where were these ideas first put to writing? Accordingly, after a discussion of preliminaria in section 1, section 2 focuses on the rhetorical devices in the text, section 3 on its key terms, and section 4 on its possible historical context. The goal of this paper is (...) not only to describe the content of the Ancient Wenzi, but also to contextualize it. That is, to explore the debate to which the Ancient Wenzi may have responded.

The arguments of Fodor, Garret, Walker and Parkes [(1980) Against definitions, Cognition, 8, 263-367] are the source of widespread skepticism in cognitive science about lexical semantic structure. Whereas the thesis that lexical items, and the concepts they express, have decompositional structure (i.e. have significant constituents) was at one time "one of those ideas that hardly anybody [in the cognitive sciences] ever considers giving up" (p. 264), most researchers now believe that "[a]ll the evidence suggests that the classical [(decompositional)] view is (...) wrong as a general theory of concepts" [Smith, Medin & Rips (1984) A psychological approach to concepts: comments on Rey, Cognition, 17, 272], and cite Fodor et al. (1980) as "sounding the death knell for decompositional theories" [MacNamara & Miller (1989) Attributes of theories of meaning, Psychological Bulletin, 106, 360]. I argue that the prevailing skepticism is unmotivated by the arguments in Fodor et al. Fodor et al. misrepresent the form, function and scope of the decompositional hypothesis, and the procedures they employ to test for the psychological reality of definitions are flawed. I argue, further, that decompositional explanations of the phenomena they consider are preferable to their primitivist alternatives, and, hence, that there is prima facie reason to accept them as evidence for the existence of decompositional structure. Cognitive scientists would, therefore, do well to revert to their former commitment to the decompositional hypothesis. (shrink)

In Nicomachean Ethics 1. 7, Aristotle gives a definition of the human good, and he does so by means of the “ ergon argument.” I clear the way for a new interpretation of this argument by arguing that Aristotle does not think that the ergon of something is always the proper activity of that thing. Though he has a single concept of an ergon, Aristotle identifies the ergon of an X as an activity in some cases but (...) a product in others, depending on the sort of thing the X is—for while the ergon of the eye is seeing, the ergon of a sculptor is a sculpture. This alternative interpretation of Aristotle’s concept of an ergon allows the key explanatory middle term of the ergon argument to be what, I argue, it ought to be: “the best achievement of a human.”.

The Logic of Causation: Definition, Induction and Deduction of Deterministic Causality is a treatise of formal logic and of aetiology. It is an original and wide-ranging investigation of the definition of causation (deterministic causality) in all its forms, and of the deduction and induction of such forms. The work was carried out in three phases over a dozen years (1998-2010), each phase introducing more sophisticated methods than the previous to solve outstanding problems. This study was intended as part (...) of a larger work on causal logic, which additionally treats volition and allied cause-effect relations (2004). The Logic of Causation deals with the main technicalities relating to reasoning about causation. Once all the deductive characteristics of causation in all its forms have been treated, and we have gained an understanding as to how it is induced, we are able to discuss more intelligently its epistemological and ontological status. In this context, past theories of causation are reviewed and evaluated (although some of the issues involved here can only be fully dealt with in a larger perspective, taking volition and other aspects of causality into consideration, as done in Volition and Allied Causal Concepts). Phase I: Macroanalysis. Starting with the paradigm of causation, its most obvious and strongest form, we can by abstraction of its defining components distinguish four genera of causation, or generic determinations, namely: complete, partial, necessary and contingent causation. When these genera and their negations are combined together in every which way, and tested for consistency, it is found that only four species of causation, or specific determinations, remain conceivable. The concept of causation thus gives rise to a number of positive and negative propositional forms, which can be studied in detail with relative ease because they are compounds of conjunctive and conditional propositions whose properties are already well known to logicians. The logical relations (oppositions) between the various determinations (and their negations) are investigated, as well as their respective implications (eductions). Thereafter, their interactions (in syllogistic reasoning) are treated in the most rigorous manner. The main question we try to answer here is: is (or when is) the cause of a cause of something itself a cause of that thing, and if so to what degree? The figures and moods of positive causative syllogism are listed exhaustively; and the resulting arguments validated or invalidated, as the case may be. In this context, a general and sure method of evaluation called ‘matricial analysis’ (macroanalysis) is introduced. Because this (initial) method is cumbersome, it is used as little as possible – the remaining cases being evaluated by means of reduction. Phase II: Microanalysis. Seeing various difficulties encountered in the first phase, and the fact that some issues were left unresolved in it, a more precise method is developed in the second phase, capable of systematically answering most outstanding questions. This improved matricial analysis (microanalysis) is based on tabular prediction of all logically conceivable combinations and permutations of conjunctions between two or more items and their negations (grand matrices). Each such possible combination is called a ‘modus’ and is assigned a permanent number within the framework concerned (for 2, 3, or more items). This allows us to identify each distinct (causative or other, positive or negative) propositional form with a number of alternative moduses. This technique greatly facilitates all work with causative and related forms, allowing us to systematically consider their eductions, oppositions, and syllogistic combinations. In fact, it constitutes a most radical approach not only to causative propositions and their derivatives, but perhaps more importantly to their constituent conditional propositions. Moreover, it is not limited to logical conditioning and causation, but is equally applicable to other modes of modality, including extensional, natural, temporal and spatial conditioning and causation. From the results obtained, we are able to settle with formal certainty most of the historically controversial issues relating to causation. Phase III: Software Assisted Analysis. The approach in the second phase was very ‘manual’ and time consuming; the third phase is intended to ‘mechanize’ much of the work involved by means of spreadsheets (to begin with). This increases reliability of calculations (though no errors were found, in fact) – but also allows for a wider scope. Indeed, we are now able to produce a larger, 4-item grand matrix, and on its basis find the moduses of causative and other forms needed to investigate 4-item syllogism. As well, now each modus can be interpreted with greater precision and causation can be more precisely defined and treated. In this latest phase, the research is brought to a successful finish! Its main ambition, to obtain a complete and reliable listing of all 3-item and 4-item causative syllogisms, being truly fulfilled. This was made technically feasible, in spite of limitations in computer software and hardware, by cutting up problems into smaller pieces. For every mood of the syllogism, it was thus possible to scan for conclusions ‘mechanically’ (using spreadsheets), testing all forms of causative and preventive conclusions. Until now, this job could only be done ‘manually’, and therefore not exhaustively and with certainty. It took over 72’000 pages of spreadsheets to generate the sought for conclusions. This is a historic breakthrough for causal logic and logic in general. Of course, not all conceivable issues are resolved. There is still some work that needs doing, notably with regard to 5-item causative syllogism. But what has been achieved solves the core problem. The method for the resolution of all outstanding issues has definitely now been found and proven. The only obstacle to solving most of them is the amount of labor needed to produce the remaining (less important) tables. As for 5-item syllogism, bigger computer resources are also needed. (shrink)

Since the noun phrase `artificial intelligence' (AI) was coined, it has been debated whether humans are able to create intelligence using technology. We shed new light on this question from the point of view of themodynamics and mathematics. First, we define what it is to be an agent (device) that could be the bearer of AI. Then we show that the mainstream definitions of `intelligence' proposed by Hutter and others and still accepted by the AI community are too weak even (...) to capture what is involved when we ascribe intelligence to an insect. We then summarise the highly useful definition of basic (arthropod) intelligence proposed by Rodney Brooks, and we identify the properties that an AI agent would need to possess in order to be the bearer of intelligence by this definition. Finally, we show that, from the perspective of the disciplines needed to create such an agent, namely mathematics and physics, these properties are realisable by neither implicit nor explicit mathematical design nor by setting up an environment in which an AI could evolve spontaneously.

Gödel’s slingshot-argument proceeds from a referential theory of definite descriptions and from the principle of compositionality for reference. It outlines a metasemantic proof of Frege’s thesis that all true sentences refer to the same object—as well as all false ones. Whereas Frege drew from this the conclusion that sentences refer to truth-values, Gödel rejected a referential theory of definite descriptions. By formalising Gödel’s argument, it is possible to reconstruct all premises that are needed for the derivation of Frege’s (...) thesis. For this purpose, a reference-theoretical semantics for a language of first-order predicate logic with identity and referentially treated definite descriptions will be defined. Some of the premises of Gödel’s argument will be proven by such a reference-theoretical semantics, whereas others can only be postulated. For example, the principle that logically equivalent sentences refer to the same object cannot be proven but must be assumed in order to derive Frege’s thesis. However, different true (or false) sentences can refer to different states of affairs if the latter principle is rejected and the other two premises are maintained. This is shown using an identity criterion for states of affairs according to which two states of affairs are identical if and only if they involve the same objects and have the same necessary and sufficient condition for obtaining.

With the advent of the semantic web, the problem of ambiguity is becoming more and more urging. Semantic analysis is necessary for explaining and resolving some sorts of ambiguity by inquiring into the relation between possibilities of predication and definition of a concept in order to solve problems such as interpretation and ambiguity. If computing is now approaching such problems of linguistic analysis, what is worth inquiring into is how the development of linguistic studies can be useful for developing (...) the theoretical background of ontologies. Our proposal is to develop a theory of definition alternative to the traditional metaphysical approach and the modern relativistic account. We interpret the ancient notion of essential definition in a dialectical perspective, and show how the dialectical definition by genus and difference corresponds to the semantic analysis of the definiendum. The dialectical definition is shown to be grounded on the deepest endoxa (shared knowledge) of a community, and to be the argumentatively strongest definition. After presenting the most common types of definition used in argumentation, the linguistic and logical characteristics of the notion of definition by genus and difference are set out in a pragmatic framework.

Legal definitions will be examined from three perspectives: their pragmatic function, their propositional structure, and their argumentative role. In law, definitions can be used for different pragmatic purposes: they can be uttered to describe a concept, or to establish a new meaning for a term. The propositional content of definitional speech acts can be different. In law, like in ordinary conversation, there might be different types of definition: we can define by providing examples, or showing the fundamental characteristics of (...) the concept defined, or listing the constituent parts of the denotatum. All these definitions play different argumentative roles in legal discourse. At a third level, definitions can be thought of as premises in complex patterns of reasoning (for the subject of reasoning from definition in law, see Aarnio 1977; Moore 1980; Lindahl, 2004). They constitute the fundamental element of argument from classification, namely a pattern of inference in which a new property (or a name) is attributed to an entity on the basis of other properties.

In this paper we analyze the uses and misuses of argumentation schemes from verbal classification, and show how argument from definition supports argumentation based on argument from verbal classification. The inquiry has inevitably included the broader study of the concept of definition. The paper presents the schemes for argument from classification and for argument from definition, and shows how the latter type of argument so typically supports the former. The problem of analyzing (...) arguments based on classification is framed in a structure that reveals the crucial role it plays in the persuasion process. The survey of the literature includes the work of Hastings, Perelman, Kienpointner and Schiappa, but still finds much of value in Aristotle. Lessons drawn from Aristotle’s Topics are shown to be useful for developing new tools for assessing definitions and arguments from definition. (shrink)

This paper examines Aristotle’s two famous claims that man is by nature a political animal, and that he is the only animal who possesses speech and reason (logos). Aristotle’s thesis that man is by nature a political animal is inextricably linked with his thesis that the polis exists by nature. This paper examines the argument that Aristotle develops in Pol. I. 2 to support these two theses. It argues a) that the definition of man as an animal who (...) possesses logos is part of this argument, b) that in the chapter Aristotle understands the term “political animal” not in a broad biological sense but in a narrow sense, c) that Aristotle’s thesis that the polis is “by nature prior to the household and to the individual” is not an independent third theorem – as David Keyt and Fred D. Miller claim – but is part of this argument. (shrink)

The paper provides some introductory comments and a preliminary translation of Avicenna’s Burhān, IV, 2. I shall first set the stage by outlining the structure of the book (sec. 1). I will then briefly introduce (sec. 2) a number of notions that are dealt with in the first treatise of the Burhān (e.g. definition, description). Burhān, IV, 2 is split into two parts: the first focuses mainly on Aristotle’s An. Post., B, 4, whereas the second covers some of the (...) topics of B, 5 and B, 6. Accordingly, sec. 3 will be devoted to a cursory presentation of Aristotle’s arguments in An. Post., B, 4 along with a more detailed discussion of its Avicennan counterpart, focusing on the indemonstrability of definition; sec. 4, finally, will be a presentation of the second part of the chapter, concerning the relationship between definition and division. An English translation of the entire chapter is appended to the paper and is accompanied by some notes. (shrink)

Many philosophers believe that our ordinary English words man and woman are “gender terms,” and gender is distinct from biological sex. That is, they believe womanhood and manhood are not defined even partly by biological sex. This sex/gender distinction is one of the most influential ideas of the twentieth century on the broader culture, both popular and academic. Less well known are the reasons to think it’s true. My interest in this paper is to show that, upon investigation, the arguments (...) for the sex/gender distinction have feet of clay. In fact, they all fail. We will survey the literature and tour arguments in favor of the sex/gender distinction, and then we’ll critically evaluate those arguments. We’ll consider the argument from resisting biological determinism, the argument from biologically intersex people and vagueness, the argument from the normativity of gender, and some arguments from thought experiments. We’ll see that these arguments are not up to the task of supporting the sex/gender distinction; they simply don’t work. So, philosophers should either develop stronger arguments for the sex/gender distinction, or cultivate a variety of feminism that’s consistent with the traditional, biologically-based definitions of woman and man.

How do we determine whether individuals accept the actual consistency of a political argument instead of just its rhetorical good looks? This article answers this question by proposing an interpretation of political argument within the constraints of political liberalism. It utilises modern developments in the philosophy of logic and language to reclaim ‘meaningless nonsense’ from use as a partisan war cry and to build up political argument as something more than a power struggle between competing conceptions of (...) the good. Standard solutions for ‘clarifying’ meaning through descriptive definition encounter difficulties with the biases of status quo idioms (long noted by theorists like William Connolly and Quentin Skinner), as well as partisan translations and circularity. Collectively called linguistic gerrymandering, these difficulties threaten political liberalism’s underlying coherency. The proposed interpretation of political argument overcomes this with a new brand of conceptual analysis that can falsifiably determine whether rhetoric has hijacked political argument. (shrink)

In this article author traces relation between argumentation and cultural practice. The first part focuses on definition of argumentation in informal logic tradition. In particular, it discusses argument in terms of verbal and social activity involving the use of everyday language. Author claims that there is no argumentation beyond language. The second part explains persuasive argumentation as a form of cultural practice. The persuasive arguments found in “social practice” can be understood as a social activity, analysable within the (...) context of a given cultural system. Author refers to an approach taking the argumentative expression as a certain type of communicative practice, directed towards respecting, recognising or accepting specific actions. The inclusion of persuasive argumentation in the “circuit of cultural activities” to be studied makes it possible to compare this type of argumentation with other social practices, and to posit a clear historical dimension in the study of argumentation. It also makes it possible to view persuasive argumentation as one of many cultural activities aimed at changing or perpetuating behaviours, attitudes, thinking, etc. The third part of the paper concerns the problem of humanistic interpretation of persuasive argumentation. Author attempts to develop this intuition, at the same time demonstrating the problems that arise from this approach. In conclusion, author tries to analyze argumentation in terms of culture theory and humanistic interpretation. (shrink)

Scholars have often thought that a monistic reading of Aristotle’s definition of the human good – in particular, one on which “best and most teleios virtue” refers to theoretical wisdom – cannot follow from the premises of the ergon argument. I explain how a monistic reading can follow from the premises, and I argue that this interpretation gives the correct rationale for Aristotle’s definition. I then explain that even though the best and most teleios virtue must be (...) a single virtue, that virtue could in principle be a whole virtue that arises from the combination of all the others. I also clarify that the definition of the human good aims at capturing the nature of human eudaimonia only in its primary case. (shrink)

This dissertation is an analysis of the development of dialectic and argumentation theory in post-classical Islamic intellectual history. The central concerns of the thesis are; treatises on the theoretical understanding of the concept of dialectic and argumentation theory, and how, in practice, the concept of dialectic, as expressed in the Greek classical tradition, was received and used by five communities in the Islamic intellectual camp. It shows how dialectic as an argumentative discourse diffused into five communities (theologicians, poets, grammarians, philosophers (...) and jurists) and how these local dialectics that the individual communities developed fused into a single system to form a general argumentation theory (adab al-bahth) applicable to all fields. I evaluate a treatise by Shams al-Din Samarqandi (d.702/1302), the founder of this general theory, and the treatises that were written after him as a result of his work. I concentrate specifically on work by Adud al-Din al-Iji (d.756/1355), Sayyid Sharif al-Jurjani (d.816/1413), Taşköprüzâde (d.968/1561), Saçaklızâde (d.1150/1737) and Gelenbevî (d.1205/1791) and analyze how each writer (from Samarqandi to Gelenbevî) altered the shape of argumentative discourse and how later intellectuals in the post-classical Islamic world responded to that discourse bequeathed by their predecessors. What is striking about the period that this dissertation investigates (from 1300-1800) is the persistence of what could be called the linguistic turn in argumentation theory. After a centuries-long run, the jadal-based dialectic of the classical period was displaced by a new argumentation theory, which was dominantly linguistic in character. This linguistic turn in argumentation dates from the final quarter of the fourteenth century in Iji's impressively prescient work on 'ilm al-wad'. This idea, which finally surfaced in the post-classical period, that argumentation is about definition and that, therefore, defining is the business of language—even perhaps, that language is the only available medium for understanding and being understood—affected the way that argumentation theory was processed throughout most of the period in question. The argumentative discourse that started with Ibn al-Rawandi in the third/ninth century left a permanent imprint on Islamic intellectual history, which was then full of concepts, terminology and objectives from this discourse up until the late nineteenth century. From this perspective, Islamic intellectual history can be read as the tension between two languages: the "language of dialectic" (jadal) and the "language of demonstration" (burhan), each of which refer not only to a significant feature of that history, but also to a feature that could dramatically alter the interpretation of that history.

Definition of the problem The umbrella term “explicability” refers to the reduction of opacity of artificial intelligence (AI) systems. These efforts are challenging for medical AI applications because higher accuracy often comes at the cost of increased opacity. This entails ethical tensions because physicians and patients desire to trace how results are produced without compromising the performance of AI systems. The centrality of explicability within the informed consent process for medical AI systems compels an ethical reflection on the trade-offs. (...) Which levels of explicability are needed to obtain informed consent when utilizing medical AI? Arguments We proceed in five steps: First, we map the terms commonly associated with explicability as described in the ethics and computer science literature, i.e., disclosure, intelligibility, interpretability, and explainability. Second, we conduct a conceptual analysis of the ethical requirements for explicability when it comes to informed consent. Third, we distinguish hurdles for explicability in terms of epistemic and explanatory opacity. Fourth, this then allows to conclude the level of explicability physicians must reach and what patients can expect. In a final step, we show how the identified levels of explicability can technically be met from the perspective of computer science. Throughout our work, we take diagnostic AI systems in radiology as an example. Conclusion We determined four levels of explicability that need to be distinguished for ethically defensible informed consent processes and showed how developers of medical AI can technically meet these requirements.

In lieu of an abstract, here is a brief excerpt of the content:Philosophies versus Philosophy:In Defense of a Flexible DefinitionRein RaudIt is strange that no one has taken up Carine Defoort's clearly formulated and timely argument about the intercultural tensions in interpreting what philosophy is, although the issue deserves at least a roundtable, if not an international conference.1 I doubt that this is because there is a general consensus that the matter is now settled, and I would therefore like (...) to develop the argument a bit further and offer a few additional factors to consider. It is also obvious that the problem is not limited to the subject of Chinese philosophy alone: all traditions of thought from all over the world, but most notably the Indian, Islamic, and Japanese heritages, are affected by the positions we adopt. As in most debates about the commensurability of cultural traditions, we can find differences when we look for them, and similarities if these are what we would like to see, so the "conflict of sensitivities"2 is also a matter of attitudes. My own position is that regardless of what we prefer to call the practice of deeper thought (and 'philosophy' is a very good name), it would be extremely useful for all of its participants, whatever their origin and upbringing, to find a common denominator for them to be able to exchange ideas and mutually enrich each other on its basis. In what follows I shall try to sketch a perspective from which this could, in my opinion, be theoretically grounded.Four PositionsDefoort has identified four possible points of view on the problem of whether classical Chinese thought could or should be called 'philosophy,' which could be summarized as follows.1. Chinese classical thought is not philosophy, because it does not satisfy the conditions of philosophy as it is generally and traditionally understood in the West.2. Chinese classical thought is philosophy, because it reveals the necessary characteristics if analyzed with the help of an appropriate (Western-type) observation language.3. Chinese classical thought can be called philosophy, but only if we redefine philosophy in order to accommodate some of its nontypical or clearly deviant features.4. Chinese classical thought should not be called philosophy, because philosophy is a culturally closed Western phenomenon with a limited scope and incapable of understanding fundamentally different modes of thought. [End Page 618]If we dismiss the birthright variety of the first position, we could label it essentialist, and its weakest point is certainly that Western philosophy has not remained unchanged during the course of history. It is highly doubtful that Socrates, Diogenes, scholastics, Nietzsche, and Gareth Evans could all be members of the same set if the same strict criteria were applied to all periods and all cultural settings in the same way, and, as Defoort herself stresses,3 the fact that seventeenth-century Jesuits (the basis of whose original worldview, we should think, was much farther from the Chinese than ours) had no problem in calling Chinese thought philosophy should show us that the paradigm shift of the thing called 'philosophy' has occurred in the West and is, so to speak, our problem and not theirs.Now, it is also possible that in some circles even some prominent names in the Western tradition do not qualify as real philosophers, in the sense in which Hegel was treated by Bertrand Russell4 and Heidegger was dismissed by Alfred Ayer5 in their respective histories of philosophy (while they nevertheless felt compelled to include chapters or passages on them). A definition of philosophy that puts forward such criteria that a considerable number of thinkers would have to remain outside its borders should be labeled sectarian-and it can still be met, even if ever less often, in some analytical schools of philosophy. It is my conviction, however, that in our globalizing world any definition that would leave non-European philosophy outside the borders of 'philosophy proper' should be considered sectarian in nature. The main problem that I have with Defoort's family model6 is precisely that in it the head of the family, who makes the decisions as to who can be adopted and who cannot, is always Western, and the...

The purpose of this paper is to inquire into the relationship between persuasive definition and common knowledge (propositions generally accepted and not subject to dispute in a discussion). We interpret the gap between common knowledge and persuasive definition (PD) in terms of potential disagreements: PDs are conceived as implicit arguments to win a potential conflict. Persuasive definitions are analyzed as arguments instantiating two argumentation schemes, argument from classification and argument from values, and presupposing a potential disagreement. (...) The argumentative structure of PDs reveals different levels of disagreement, and different pos-sibilities of resolving the conflict or causing dialogical deadlock. (shrink)

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed (...) for finding missing reasons, for deductive arguments, e.g., semantic tableaux are suggested.

In the complex tapestry of existence, we journey down the corridors of thought, proclaiming Descarte's famed words: "Cogito ergo sum." Yet, the journey does not conclude with merely affirming our existence but falls down the endless pit of the dimensions and complex corridors of free will and autonomy. Let us establish the terms that shall guide our thoughts for this voyage. First, a multi-faceted free will that transcends mere ownership of thoughts, extending to the profound responsibility for our actions within (...) the temporal plane we inhabit," an existence yet to be fully revealed. Second, the insistence on the necessity, or at least the belief in the potential, of self-control. Here, we differ from conventional definitions of free will to assert the capacity to govern the mind and ego, even when one perceives a lack of control. The mind, which exists somewhere, owns the authority over its thoughts, which is you. And thirdly, the elusive question: What is "I"? Not into the human "you" or the one that speaks and sees but into the core thinker, the intangible essence that animates. The "I" resides within, shaping the tangible reality and, paradoxically, depending on nothing while being the core of reality. Yet, the pivotal question still stands: Do others exist? Autonomy becomes the litmus test. If I, as an autonomous being, fail to wield dominion over external circumstances. Weakness in reshaping the external world confirms the separation, a stark admission of being powerless in the face of objective reality. While using ocoms razer, our answer is found. Thus, the conclusion is a solitary existence in the ability to affirm one's own being while recognizing others through autonomy. (shrink)

Presumption is a complex concept in law, affecting the dialogue setting. However, it is not clear how presumptions work in everyday argumentation, in which the concept of “plausible argumentation” seems to encompass all kinds of inferences. By analyzing the legal notion of presumption, it appears that this type of reasoning combines argument schemes with reasoning from ignorance. Presumptive reasoning can be considered a particular form of reasoning, which needs positive or negative evidence to carry a probative weight on the (...) conclusion. For this reason, presumptions shift the burden of providing evidence or explanations onto the interlocutor. The latter can provide new information or fail to do so: whereas in the first case the new information rebuts the presumption, in the second case, the absence of information that the interlocutor could reasonably provide strengthen the conclusion of the presumptive reasoning. In both cases the result of the presumption is to strengthen the conclusion of the reasoning from lack of evidence. As shown in the legal cases, the effect of presumption is to shift the burden of proof to the interlocutor; however, the shift a presumption effects is only the shift of the evidential burden, or the burden of completing the incomplete knowledge from which the conclusion was drawn. The burden of persuasion remains on the proponent of the presumption. On the contrary, reasoning from definition in law is a conclusive proof, and shifts to the other party the burden to prove the contrary. This crucial difference can be applied to everyday argumentation: natural arguments can be divided into dialectical and presumptive arguments, leading to conclusions materially different in strength. -/- .

I consider what I hope are increasingly sophisticated versions of ontological argument, beginning from simple definitional forms, through three versions to be found in Anselm, with their recent interpretations by Malcolm, Plantinga, Klima and Lowe. I try to show why none of these work by investigating both the different senses of necessary existence and the conditions under which logically necessary existence can be brought to bear. Although none of these arguments work, I think that they lead to interesting reflections (...) on the nature of definition, on the conditions for possessing the property of necessary existence and point towards a different, neo-Platonic ground for God’s meeting the criteria for being logically necessary.

Although the last decade has seen a proliferation of ontological approaches to arguments, many of them employ ad hoc solutions to representing arguments, lack interoperability with other ontologies, or cover arguments only as part of a broader approach to evidence. To provide a better ontological representation of arguments, we present the Arguments Ontology (ArgO), a small ontology for arguments that is designed to be imported and easily extended by researchers who work in different upper-level ontology frameworks, different logics, and different (...) approaches to argument evaluation. Unlike most ontological approaches to arguments, ArgO utilizes Basic Formal Ontology (BFO) as an upper-level ontology, and may be used alongside other commonly used ontologies in the BFO framework, including boththe Information Artifact Ontology (IAO), and the Information Entity Ontology (INFO). Critically, our proposal is principled, based on rigorous definitions and formal axioms out of which characterizations of arguments naturally fall. It is our hope that ArgO may assist researchers in many projects, including: integrating heterogeneous sources of evidence, structuring the content of semantic wikis, and enhancing semantic reasoning.

This book shows how research in linguistic pragmatics, philosophy of language, and rhetoric can be connected through argumentation to analyze a recognizably common strategy used in political and everyday conversation, namely the distortion of another’s words in an argumentative exchange. Straw man argumentation refers to the modification of a position by misquoting, misreporting or wrenching the original speaker’s statements from their context in order to attack them more easily or more effectively. Through 63 examples taken from different contexts (including political (...) and forensic discourses and dialogs) and 20 legal cases, the book analyzes the explicit and implicit types of straw man, shows how to assess the correctness of a quote or a report, and illustrates the arguments that can be used for supporting an interpretation and defending against a distortion. The tools of argumentation theory, a discipline aimed at investigating the uses of arguments by combining insights from pragmatics, logic, and communication, are applied to provide an original account of interpretation and reporting, and to describe and illustrate tactics and procedures that can be used and implemented for practical purposes.. This book will appeal to scholars in the fields of political communication, communication in general, argumentation theory, rhetoric and pragmatics, as well as to people working in public speech, speech writing, and discourse analysis.

Despite its enormous popularity, Russell’s theory of definite descriptions has received various criticisms. Two of the most important objections against this theory are those arising from the Argument from Incompleteness and the Argument from Donnellan’s Distinction. According to the former although a speaker may say something true by assertively uttering a sentence containing an incomplete description , on the Russellian analysis such a sentence expresses a false proposition; so, Russell’s theory cannot adequately deal with such sentences. According to (...) the latter objection a descriptive sentence is actually ambiguous—it expresses a general proposition when the description contained in it is used attributively, and a singular proposition when the description in question is used referentially; Russell’s theory is inadequate as it fails to capture this ambiguity and offers an analysis according to which a descriptive sentence expresses only a general proposition. These objections are examined in the present dissertation. It is shown here that these objections arise from: (i) ignoring the distinction between the meaning of a sentence and the assertions made by using it, (ii) the failure to distinguish between the semantic meaning of a sentence and the pragmatic meaning with which it is used on a particular occasion. To make the distinction mentioned in (i), a significant part of Scott Soames’ theory concerning meaning and assertions has been adopted in this dissertation; and, to make the distinction mentioned in (ii), a test, namely the cancellability test, and two Distinguishing Criteria, namely DC-1 and DC-2, have been developed here. It has been argued here that if we properly make the relevant distinctions, then we will find that: (a) the phenomenon cited by the Argument from Incompleteness can be well explained keeping the Russellian analysis of descriptive sentences intact, (b) the phenomenon arising from the Argument from Donnellan’s Distinction raises an issue of pragmatics and is irrelevant to Russell’s semantic analysis of descriptive sentences. So, none of the above criticisms poses a genuine threat to Russell’s theory of definite descriptions; his theory actually provides, to a large extent, a correct semantic analysis of descriptive sentences.

In Boghossian's 1997 paper, 'Analyticity' he presented an account of a prioriknowledge of basic logical principles as available by inference from knowledge of their role in determining the meaning of the logical constants by implicit definitiontogether with knowledge of the meanings so-determined that we possess through ourprivileged access to meaning. Some commentators (e.g. BonJour (1998), Glüer (2003),Jenkins (2008)) have objected that if the thesis of implicit definition on which he relieswere true, knowledge of the meaning of the constants would (...) presuppose knowledge of the very logical principles knowledge of which the account purports to explain. Aconsequence would seem to be that implicit definition is incompatible with privilegedaccess. I argue that whilst it is possible for Boghossian to defend against theseobjections the form of argument he proposes does exhibit a subtle form of questionbegging such that it exhibits a transmission of warrant-failure.

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary (...) logic of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)
