Two opposed movements of thought threaten philosophy as an autonomous practice from the inside: scientific naturalism and quietism. Naturalism (qua methodological thesis) threatens to turn philosophy into a mere ancilla of the sciences, quietism understood as the prescription to remain silent in philosophy would not countenance any more "positive" philosophy. This book reconstructs naturalism and quietism such that it becomes clear naturalism does have the potential to end philosophy as an autonomous practice and that quietism, correctly understood, does not. To (...) this end, this book provides arguments against the prevailing orthodox status of naturalism and a heterogenous reading of Wittgenstein's metaphilosophical quietism as the rejection of a certain kind of theories in philosophy, namely quasi-scientific theories.

: This paper outlines a genuinely pragmatist conception of propensity, and defends it against common objections to the propensity interpretation of probability, prominently Humphreys’ paradox. The paper reviews the paradox and identifies one of its key assumptions, the identity thesis, according to which propensities are probabilities. The identity thesis is also involved in empiricist propensity interpretations deriving from Popper’s influential original proposal, and makes such interpretations untenable. As an alternative, I urge a return to Charles Peirce’s original insights on probabilistic (...) dispositions, and offer a reconstructed version of his pragmatist conception, which rejects the identity thesis. – Correspondence to: [email protected].

This volume examines the entire logical and philosophical production of Nikolai A. Vasil’ev, studying his life and activities as a historian and man of letters. Readers will gain a comprehensive understanding of this influential Russian logician, philosopher, psychologist, and poet. The author frames Vasil’ev’s work within its historical and cultural context. He takes into consideration both the situation of logic in Russia and the state of logic in Western Europe, from the end of the 19th century to the beginning of (...) the 20th. Following this, the book considers the attempts to develop non-Aristotelian logics or ideas that present affinities with imaginary logic. It then looks at the contribution of traditional logic in elaborating non-classical ideas. This logic allows the author to deal with incomplete objects just as imaginary logic does with contradictory ones. Both logics are objects of interesting analysis by modern researchers. (shrink)

Discussions of the relation between pragmatism and logical empiricism tend to focus on the period when the logical empiricists found themselves in exile, mostly in the United States, and then attempt to gauge the actual extent of their convergence. My concern lies with the period before that and the question whether pragmatism had an earlier influence on the development of logical empiricism, especially on the thought of the former members of the “first” Vienna Circle. I argue for a substantially qualified (...) affirmative answer. (shrink)

as a critical thinking instructor, the coronavirus pandemic has been a once-in-a-lifetime opportunity to observe how people weigh evidence, assess risk, and make value decisions. From the micro level of daily individual habits to the macro level of our species' global response, every scale of our lives has required some degree of adaptation to this crisis. Unfortunately, my training and profession do not guarantee that my decisions and behavior are any better than yours. I am as fallible as anyone, but (...) perhaps my background has provided me with more tools for coping with doubt.

The word ‘true’ shows some evidence of gradability. For instance, there are cases where truth-bearers are described as ‘slightly true’, ‘completely true’ or ‘very true’. Expressions that accept these types of modifiers are analysed in terms of properties that can be possessed to a greater or lesser degree. If ‘true’ is genuinely gradable, then it would follow that there are degrees of truth. It might also follow that ‘true’ is context-sensitive, like other gradable expressions. Such conclusions are difficult to reconcile (...) with most existing theories: deflationists and inflationists alike tend to reject the thesis that one true truth-bearer can have more or less truth than another. Based on work in natural language, I argue that ‘true’ is not a genuinely gradable expression. I also provide an explanation of the apparent evidence for gradability. Hence there is no reason to think that there is a truth property that comes in degrees. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume's Demarcation Project John Losee Demarcation, Ideas and Impressions David Hume sought to exclude certain concepts from the domain of empirically significant discourse. He was critical of talk about "substances" that bear qualities, "forces" that cause motions, "powers" that produce effects, "necessary connections" that determine sequences of events, "extension without matter" and "time independent of succession or change in any real existence."1 Hume proposed a demarcation ofideas, a demarcation (...) intended to exclude these notions. The demarcation project, if successful, would exclude Locke's notion of "substance" as well as Newton's notions of "Absolute Space" and "Absolute Time." Some interpreters have taken the demarcation project to be the centrepiece of Hume's philosophy. Others have seen it to be an incidental aspect of Hume's search for an empirical theory of human nature. I believe that David Pears was correct to insist that an acceptable account ofHume's philosophy include both the "destructive emphasis" and the "constructive emphasis."2 Hume's demarcation project is based on a presumed relation, or relations, between ideas and impressions. Hume made the following claims about "simple ideas," those ideas that "admit of no distinction nor separation" (T 2): 1)every simple idea in its first appearance is derived from some impression (Derivability Principle); 2)every simple idea in its first appearance copies some impression (Copy Principle); 3)every simple idea represents some impression (Representation Principle); 4)simple ideas and impressions resemble one another; 5)simple ideas correspond to impressions; 6)every simple idea is borroVd from some impression; Volume XVII Number 2 51 JOHN LOSEE 7)for every simple idea there is some temporally antecedent impression; and 8)impressions cause simple ideas. Primafacie, these claims are empirical claims about the genesis of our ideas. But within Hume's demarcation project these claims also function as criteria for membership in the class of simple ideas. Those ideas that satisfy the criteria constitute raw material from which complex ideas are formulated. Complex ideas are constructed from simple ideas. However, they are not copies of simple ideas. Aparticular complex idea is empirically significant provided that, 1) it is derivable from simple ideas; and 2) each of those simple ideas is derivable from impressions. The Case of the Missing Shade ofBlue Tensions arise within the demarcation project in part because Hume employs nonequivalent criteria—Derivability Principle, Copy Principle, Representation Principle—as if they were equivalent. The tension is acute in the case of the missing shade ofblue. The "missing shade" is an idea formulated by a person with extensive experience of colours, but no prior exposure to the shade in question. If this idea is a simple idea, then it is false that every simple idea copies some antecedent impression. Why did Hume cite—in both Treatise and Inquiry—this apparently destructive exception? Bernard Rollin has suggested that Hume may have cited the missing-shade-of-blue example as a rhetorical device toprotecthis dichotomous divisionofpropositionsinto those that are analytic a priori and those that are synthetic a posteriori (including the Derivabihty Principle).11 John O. Nelson agreed that Hume is concerned to emphasize the contingent, empirical status of the Derivabihty Principle.12 Nelson suggested that Hume sought tomake two points. The first pointis that an exception to the Derivability Principle is empirically possible. The second point is that thought-experiments like the missing-shade example are inadequate to establish conclusions about matters offact. To entertain such thought-experiments is to lapse into hypothetical speculation, a violation ofthe "experimental method ofreasoning."13 Perhaps it was for this reason that Hume dismissed the missing-shade case as unimportant. Hume urged that this case is "so particular and singular" thatit provides nogoodreason to abandon the Copy Principle (T 6). 52Hume Studies HUME'S DEMARCATION PROJECT D. M. Johnson has developed a hypothesis to explain why Hume believed that this exceptional case is not damaging to his demarcation project. According to Johnson, Hume may have believed that for a person to reconstruct a shade he never saw before, he must have developed an appropriately detailed Tiabitual spectrum'—i.e., an ordered set oftendencies and expectations concerning colours, built up as a result oflong experience with thingshavingthese colours—whichhe then employs...

The skeptical challenge to politics is that if knowledge is in short supply and it is a condition for the proper use of political power, then there is very little just politics. Cicero’s Republicanism is posed as a program for political legitimacy wherein both citizens and their states are far from ideal. The result is a form of what is termed negative conservatism, which shows political gridlock in a more positive light.

We are pleased to release this edition of Ralph Johnson’s The Rise of Informal Logic as Volume 2 in the series Windsor Studies in Argumentation. This edition is a reprint of the previous Vale Press edition with some typographical errors and other minor mistakes corrected. The prime motive for gathering Ralph H. Johnson’s essays under one cover is their clear articulation of the goals, concerns and problems of the discipline of informal logic. To my knowledge all of the published articles, (...) even of the 1980s, are still in print. But some are obtainable only by special request of a journal back issue. Their availability, even their existence, is not nearly widely enough known, and this volume is dedicated to remedying that disservice to those currently working in the field of informal logic, critical thinking, argumentation, and practical reasoning. Three of these sixteen pieces appear here in print for the first time. The previously published pieces have appeared from 1980 to 1992 as chapters in collective works or as articles in journals, and these in turn published in Canada, USA, The Netherlands and Belgium. It is hoped that gathering this hitherto scattered material under one cover will contribute to a greater understanding of what informal logic is, and to an enhanced sense of the impact of Johnson’s ideas. A discipline of informal logic might exist today without the writings of Johnson and his frequent co-author, J. Anthony Blair. But it would almost certainly be quite different from what it actually is. (shrink)

The work done in the philosophy of modeling by Vaihinger (1876), Craik (1943), Rosenblueth and Wiener (1945), Apostel (1960), Minsky (1965), Klaus (1966) and Stachowiak (1973) is still almost completely neglected in the mainstream literature. However, this work seems to contain original ideas worth to be discussed. For example, the idea that diverse functions of models can be better structured as follows: in fact, models perform only a single function – they are replacing their target systems, but for different purposes. (...) Another example: the idea that all of cognition is cognition in models or by means of models. Even perception, reflexes and instincts (animal and human) can be best analyzed as modeling. The paper presents an analysis of the above-mentioned work. (shrink)

This dissertation addresses the problem of determining the epistemic worth of mystical based insights. Appropriating the widely accepted justified true belief theory of knowledge, it can be easily demonstrated that mystical knowledge does not satisfy the conditions of the JTB account. The question can be raised as to whether the failure of liberative knowing to qualify as "knowledge" is due to a nonepistemic character of liberation itself, or is it due to an overly stringent, inac-curate set of criteria given in (...) the JTB theory. ;The strategy adopted to answer this question is to determine the adequacy of the JTB theory. One way to judge the adequacy of a theory is to ascertain whether it adequately describes the phenom-enon it is formulated to give an account of. Here, one must determine whether the JTB theory is consonant with common usage of what constitutes "knowledge." It was determined that there are a number of modes of knowing, e.g., moral, aesthetic, intuitive, religious, which appear to be outlawed by the JTB account, yet are commonly recognized as constituting knowledge. ;On the basis of this determination, an overhaul of the JTB theory of knowledge was begun. The principal feature of this new account was to recognize that there exist numerous distinct modes of know-ing, and each mode contains its own distinct conditions that define it. Any account of knowledge must then take on a piecemeal approach which attempts to outline the various modes of knowing. There are obviously overlapping characteristics, but they do not constitute a set of necessary and sufficient conditions. This stance opens the way to a consideration of whether a mystical based knowledge is possible. Ultimately, the question of acceptance or rejection of liber-ative knowing comes down to the particular epistemological hierarchy of knowing modalities each individual adopts. One needs to consider the assorted factors or grounds that leads one to adopt or dismiss liberative knowing into one's hierarchy of knowing modalities. But one cannot attempt to dismiss one mode, such as liberative knowing, on the basis of not satisfying the criteria applicable for another mode, such as factual knowing. In the past, arguments rejecting the epis-temic content of liberative knowing have violated this prohibition. (shrink)

Philosophers have long debated ‘substrate’ and ‘bundle’ theories as to how properties hold together in objects ― but have neglected to consider that every chemical entity is defined by closure of relationships among components ― here designated ‘Closure Louis de Broglie.’ That type of closure underlies the coherence of spectroscopic and chemical properties of chemical substances, and is importantly implicated in the stability and definition of entities of many other types, including those usually involved in philosophic discourse ― such as (...) roses, statues, and tennis balls. Characteristics of composites are often presumed to ‘supervene on’ properties of components. This assumption does not apply when cooperative interactions among components are significant. Once correlations dominate, then adequate descriptions must involve different entities and relationships than those that are involved in ‘fundamental-level’ description of similar but uncorrelated systems. That is to say, descriptions must involve different semantics than would be appropriate if cooperative interactions were insignificant. This is termed ‘Closure Henri Poincaré. Networks of chemical reactions that have certain types of closure of processes display properties that make other more-complex coherences possible. This is termed ‘Closure Jacques Cauvin.’ Each of these three modes of closure provides a sufficient basis for warranted recognition of causal interaction, thus each of them has epistemological significance. Other modes of epistemologically-important closure probably exist. It is important to recognize that causal efficacy generally depends on closure of relationships of constituents. (shrink)

Due to great importance in the construction of theories it is imperative to analyze the nature of time and space and their use by scholars, societies and subjects. This text is the product of such analysis. My claim is that the validity of an argument depends on the spatial and temporal conditions that it is produced in. Moreover, I posit that time and space have been used in order to impose regimes of oppression over different collectives. My intention, however, is (...) not only denounced these uses because the oppression of the societies, to present the lack of such arguments. In other words, arguments based on universality of time and space have been the cornerstone of modern knowledge. This knowledge justifies regimes of oppression in different parts of the world. However, the intention of this analysis is not to denounce the lack of humanism in this knowledge, but to present the falsehood or incompleteness of this knowledge. It is not only wrong because its lack of humanity which justifies the inhuman regimes of oppression. It is also wrong, since its premises are false. (shrink)
