Suppositional reasoning can seem spooky. Suppositional reasoners allegedly (e.g.) “extract knowledge from the sheer workings of their own minds” (Rosa), even where the knowledge is synthetic a posteriori. Can literary fiction pull such a rabbit out of its hat? Where P is a work’s fictional ‘premise’, some hold that some works reason declaratively (supposing P, Q), imperatively (supposing P, do Q), or interrogatively (supposing P, Q?), and that this can be a source of knowledge if the reasoning is (...) good. True, I will argue, although only within the context of judicious critical interpretation. Further evident constraints include that the form of the suppositional reasoning needs to be declarative or imperative, and that the fictional ‘premise’ of the work needs to be a metaphysical counterfactual possibility, not merely a temporal counterfactual and not merely an epistemic possibility or probabilistic supposition.

In a 2002 article Stewart Cohen advances the “bootstrapping problem” for what he calls “basic justification theories,” and in a 2010 followup he offers a solution to the problem, exploiting the idea that suppositional reasoning may be used with defeasible as well as with deductive inference rules. To curtail the form of bootstrapping permitted by basic justification theories, Cohen insists that subjects must know their perceptual faculties are reliable before perception can give them knowledge. But how is such knowledge (...) of reliability to be acquired if not through perception itself? Cohen proposes that such knowledge may be acquired a priori through suppositional reasoning. I argue that his strategy runs afoul of a plausible view about how epistemic principles function; in brief, I argue that one must actually satisfy the antecedent of an epistemic principle, not merely suppose that one does, to acquire any justification by its means – even justification for a merely conditional proposition.

James Van Cleve raises some objections to my attempt to solve the bootstrapping problem for what I call “basic justification theories.” I argue that given 1 the inference rules endorsed by basic justification theorists, we are a priori (propositionally) justified in believing that perception is reliable. This blocks the bootstrapping result.

To suppose X means to pretend to change one's belief for the sake of the argument to include X. How to do so is a decision problem: of the many ways to modify one's beliefs to include X, one should choose the one that best fits with one's epistemic goals. I examine the role of suppositional reasoning in the evaluation of purported scientific explanations of various sorts, based on Hempel and Oppenheim's deductive-nomological and inductive-statistical explanations. First, I present for (...) each type of explanation the suppositional reasoning conditions it must satisfy. For example, the dipping of blue litmus paper in acid explains why it turned red only if, when one supposes that the litmus paper was not dipped in acid, one must also give up the belief that it turned red. Second, I argue that a specific decision making method should be used to determine how one is to change one's beliefs for the sake of the argument in each case. Third, I evaluate in detail whether purported explanations, both intuitively explanatory and intuitively non-explanatory satisfy these conditions. Fourth, I show that the suppositional reasoning conditions for explanations, when evaluated correctly, systematically solve the many counterexamples to the original Hempel-Oppenheim model. (shrink)

An application of the Method of Analysis of Relational Complexity (MARC) to suppositional reasoning in the knight-knave task is outlined. The task requires testing suppositions derived from statements made by individuals who either always tell the truth or always lie. Relational complexity (RC) is defined as the number of unique entities that need to be processed in parallel to arrive at a solution. A selection of five ternary and five quaternary items were presented to 53 psychology students using a (...) pencil and paper format. A computer-administered version was presented to 50 students. As predicted, quaternary problems were associated with higher error rates and longer response times than ternary problems. The computer-administered form was more difficult than the pencil and paper version of the test. These differences are discussed in terms of RC theory and alternative processing accounts. Together, they indicate that the relational complexity metric is a useful and parsimonious way to quantify complexity of reasoning tasks. (shrink)

The aim of this paper is to investigate two related aspects of human reasoning, and use the results to construct an automated theorem prover for the predicate calculus that at least approximately models human reasoning. The result is a non-resolution theorem prover that does not use Skolemization. It involves two central ideas. One is the interest constraints that are of central importance in guiding human reasoning. The other is the notion of suppositional reasoning, wherein one makes a supposition, draws (...) inferences that depend upon that supposition, and then infers a conclusion that does not depend upon it. Suppositional reasoning is involved in the use of conditionals and reductio ad absurdum, and is central to human reasoning with quantifiers. The resulting theorem prover turns out to be surprisingly efficient, beating most resolution theorem provers on some hard problems. (shrink)

We argue that relating to myself as me provides, as such, a reason to care about myself: grasping that an event involves me, instead of another, makes it matter in a special way. Further, this self-concern is not simply a matter of seeing in myself some instrumental value for other ends. We use as our foil a recent skeptical challenge to this view offered in Setiya (2015). We think the case against self-concern is powered by unwarrantedly narrow construals of three (...) key notions. One is the notion of a first-personal way of relating to oneself. A narrow account of the first person in terms of special epistemic relations to oneself makes it easy to overlook a source of non-instrumental reasons of self-concern, located in the special relation a subject has to herself as agent. Two is the notion of what it is to be a reason. And three is the notion of self-concern itself. We show that the skeptical case rests in part on a slide towards neighbouring but distinct notions of egoism and selfishness. We also argue that Setiya’s notion of self-love, offered to capture the pre-theoretical intuition of self-concern, cannot do it justice. (shrink)

Deductive reasoning shares with other forms of thinking a reliance on strategies, as shown by the results of three experiments on the nature and development of control strategies to solve suppositional deductions. These puzzles are based on assertors who may or may not be telling the truth, and their assertions about their status as truthtellers and liars. The first experiment shows that reasoners make backward inferences as well as forward inferences, to short-cut their way through the alternatives, and the (...) generation of suppositions is a source of difficulty. The second experiment establishes that the elimination of the suppositional status of an individual does not render problems easier. The third experiment shows that reasoners can improve their reasoning accuracy and speed spontaneously, without feedback, and it clarifies the transfer of strategies and their development. We discuss the implications of these data for alternative theories of suppositional deduction and for the relationship between reasoning and other forms of thinking such as problem solving. (shrink)

Two experiments investigated inferences based on suppositions. In Experiment 1, the subjects decided whether suppositions about individuals' veracity were consistent with their assertions—for example, whether the supposition “Ann is telling the truth and Beth is telling a lie”, is consistent with the premises: “Ann asserts: I am telling the truth and Beth is telling the truth. Beth asserts: Ann is telling the truth”. It showed that these inferences are more difficult than ones based on factual premises: “Ann asserts: I live (...) in Dublin and Beth lives in Dublin”. There was no difference between problems about truthtellers and liars, who always told the truth or always lied, and normals, who sometimes told the truth and sometimes lied. In Experiment 2, the subjects made inferences about factual matters set in three contexts: a truth-inducing context in which friends confided their personality characteristics, a lie-inducing context in which business rivals advertised their products, and a neutral context in which computers printed their program characteristics. Given the supposition that the individuals were lying, it was more difficult to make inferences in a truth-inducing context than in the other two contexts. We discuss the implications of our results for everyday reasoning from suppositions, and for theories of reasoning based on models or inference rules. (shrink)

The senses, or sensory modalities, constitute the different ways we have of perceiving the world, such as seeing, hearing, touching, tasting and smelling. But how many senses are there? How many could there be? What makes the senses different? What interaction takes place between the senses? This book is a guide to thinking about these questions. Together with an extensive introduction to the topic, the book contains the key classic papers on this subject together with nine newly commissioned essays.One reason (...) that these questions are important is that we are receiving a huge influx of new information from the sciences that challenges some traditional philosophical views about the senses. This information needs to be incorporated into our view of the senses and perception. Can we do this whilst retaining our pre-existing concepts of the senses and of perception or do we need to revise our concepts? If they need to be revised, then in what way should that be done? Research in diverse areas, such as the nature of human perception, varieties of non-human animal perception, the interaction between different sensory modalities, perceptual disorders, and possible treatments for them, calls into question the platitude that there are five senses, as well as the pre-supposition that we know what we are counting when we count them as five.This book will serve as an inspiring introduction to the topic and as a basis from which further new research will grow.

We report the results of three experiments designed to assess the role of suppositions in human reasoning. Theories of reasoning based on formal rules propose that the ability to make suppositions is central to deductive reasoning. Our first experiment compared two types of problem that could be solved by a suppositional strategy. Our results showed no difference in difficulty between problems requiring affirmative or negative suppositions and very low logical solution rates throughout. Further analysis of the error data showed (...) a pattern of responses, which suggested that participants reason from a superficial representation of the premises in these arguments and this drives their choice of conclusion. Our second experiment employed a different set of suppositional problems but with extremely similar proofs in terms of the rules applied and number of inferential steps required. As predicted by our interpretation of reasoning strategies employed in Experiment 1, logical performance was very much higher on these problems. Our third experiment showed that problems that could be solved by constructing an initial representation of the premises were easier than problems in which this representation was not sufficient. This effect was independent of the suppositional structure of the problems. We discuss the implications of this research for theories of reasoning based on mental models and inference rules.

Case-based reasoning is a familiar method of evaluating sentences. But when applied to conditionals, it seems to lead to implausible conclusions. In this paper I argue that the problem arises from equating the probability of a conditional sentence on the evidential supposition of some condition with the conditional probability of the former, given the latter.

A Meta-Philosophy exploration of immanent and non-immanent features of first-order philosophy in terms of the values of non- values or negative values of Radical Scepticism, Nihilism and Minarchy, executed to show how philosophizing is done. -/- It misleadingly seems as if there is no progress in philosophy as, like in visual art, literature and music, each original thinker re-invents the entire discipline, its aims, purposes, values, methods, etc The nature of philosophical tools, methods, techniques and skills will be investigated and (...) applied in terms of radical scepticism. -/- This approach, set of values and attitude restrict the nature and the style of the meta-philosophizing. It will for example prevent the traditional development of a general, all-encompassing and all-inclusive metaphysical system. It also demands the focus on context-specific investigation of questions and the dealing of a particular problem in a certain context. -/- These limits require the re-interpretation of any philosophical tool being employed as well as the underlying assumptions and any pre-suppositions. -/- As far as possible philosophizing as an aspect of the processes of theorizing will be adhered to and realized. In chapter THREE I illustrate many-leveled and multi-dimensional thinking, that are to me as a visual artist as well, of extreme importance. These are the types of things employed by radical skepticism and that should be the form of philosophizing instead of and replacing traditional one-leveled and one-dimensional thinking, argumentation and reasoning.

She has always existed and is more than a citizen of multiverses,‭ ‬most likely the ground of all.‭ ‬In the West she was introduced around C.570‭ ‬and since then many individuals have searched for her,‭ ‬tried to become familiar with her and created all sorts of,‭ ‬frequently ridiculous,‭ ‬things in her name. Once someone has a passion for her it cannot be extinguished but increases.‭ ‬Objectively this need for her is referred to as‭ ‘‬love of wisdom‭’‬,‭ ‬the need for wisdom,‭ (...) ‬while personally it is a need of some individuals. -/- This passion and need has become institutionalized and it has developed a discourse and became a socio-cultural practice of its own.‭ ‬Fairly recently it has even become a discipline at,‭ ‬mostly higher,‭ ‬institutions of learning.‭ ‬Previously those searching for and attempting to interact with her came from many walks of life and all kinds of professions,‭ ‬while in the last century or so many people began to live off her as they are remunerated for talking about,‭ ‬about the history of searching for and investigating her and saying all sorts of things about her. -/- Many things are done in her name and all sorts of neologisms are fabricated to label them,‭ ‬such as analytic,‭ ‬continental,‭ ‬idealism,‭ ‬rationalism,‭ ‬empiricism,‭ ‬and all these

disciplines and areas of life,‭ ‬such as sociology,‭ ‬the arts,‭ ‬humanities,‭ ‬cognitive sciences,‭ ‬sport,‭ ‬etc got on the bandwagon so that we now have a philosophy or love of wisdom,‭ ‬epistemologies,‭ ‬ontologies etc of everything under the sun.‭ ‬Even if you were to write some theses or do some study you will stipulate your epistemology,‭ ‬ontology,‭ ‬methodology,‭ ‬etc.‭ ‬Just

Based on extensive research conducted by the authors, Reasoning and Sense Making in the Mathematics Classroom, Pre-K-Grade 2, is designed to help classroom teachers understand, monitor, and guide the development of students' reasoning and sense making about core ideas in elementary school mathematics. It describes and illustrates the nature of these skills using classroom vignettes and actual student work in conjunction with instructional tasks and learning progressions to show how reasoning and sense making develop and how instruction can support students (...) in that development. Students who can make sense of mathematical ideas can apply those ideas in problem solving, even in unfamiliar situations, and can use them as a foundation for future learning. Without them, students are reduced to rote learning, often experiencing frustration and failure. But what do reasoning and sense making during learning and teaching look like? Each chapter of Reasoning and Sense Making in the Mathematics Classroom, Pre-K-Grade 2 explores a different topic that young children encounter in mathematics, demonstrating with actual student work and classroom dialogue how their mathematical knowledge and reasoning ability move through "levels of sophistication" or learning progressions: After opening with a discussion of the nature of reasoning and sense making and their critical importance in developing mathematical thinking, chapter 1 examines how young students attempt to make sense of the concepts of place value and length measurement. Chapter 2 focuses on how early childhood instruction can engage students in mathematical reasoning while helping them construct a rich sense of number and operations. Chapter 3 identifies core algebraic ideas and shows how students can engage with these ideas in ways that not only deepen their understanding of arithmetic but also lays the foundation for the future study of algebra. Children's reasoning and sense making as they decompose and compose geometric shapes--including reasoning about area--is examined in chapter 4. The use of learning progressions to understand students' reasoning and to guide their sense making with appropriate teaching is also discussed. Not just a theoretical discussion, the book also provides specific suggestions for related instructional activities for each topic. Supplementary online resources can be accessed at NCTM's More4U website. Reasoning and Sense Making in the Mathematics Classroom, Pre-K-Grade 2 will be a valuable and practical addition to your professional library. (shrink)

ABSTRACT The criteria for adequate explanation have been the subject of intense debate in the philosophy of social science. This paper examines a variety of explanations of a decade of violence in Kampuchea in order to clarify the dimensions of the Kampuchean tragedy and to challenge both the hypothetico‐deductive and the Verstehen models of explanation central to contemporary debates in the philosophy of social science. Using the Kampuchean case as an example, I suggest that the analyst's propensity to assimilate new (...) information into a tacit, pre‐supposition‐laden conceptual framework contributes to an oversimplification or caricature of the event to be explained. For this reason, no individual explanation of an event can be definitive. An adequate explanation can emerge only from the juxtaposition of and extrapolation from multiple, non‐privileged interpretations representing different methodological and ideological perspectives on the socio‐political event to be explained.

If a conclusion was reached that creatures without a language capability exhibit some form of a capability for logic, this would shed a new light on the relationship between logic, language, and thought. Recent experimental attempts to test whether some animals, as well as pre-linguistic human infants, are capable of exclusionary reasoning are taken to support exactly that conclusion. The paper discusses the analyses and conclusions of two such studies: Call’s (2004) two cups task, and Mody and Carey’s (2016) four (...) cups task. My paper exposes hidden assumptions within these analyses, which enable the authors to settle on the explanation which assigns logical capabilities to the participants of the studies, as opposed to the explanations which do not. The paper then demonstrates that the competing explanations of the experimental results are theoretically underdeveloped, rendering them unclear in their predictions concerning the behavior of cognitive subjects, and thus difficult to distinguish by use of experiments. Additionally, it is questioned whether the explanations are rivals at all, i.e. whether they compete to explain the cognitive processes of the same level. The contribution of the paper is conceptual. Its aim is to clear up the concepts involved in these analyses, in order to avoid oversimplified or premature conclusions about the cognitive abilities of pre- and non-linguistic creatures. It is also meant to show that the theoretical space surrounding the issues involved might be much more diverse and unknown than many of these studies imply. (shrink)

In this response, we first tackle what we take to be the core disagreement between ourselves and Hammersley, namely the justification for our model of social research ethics governance. We then consider what follows from our defence of governance for ethics review and show how these claims attend to the specific concerns outlined by Hammersley.

Arguments and conditionals are powerful means language provides us to reason about possibilities and to reach conclusions from premises. These two kinds of constructions exhibit several affinities—e.g., they both come in different varieties depending on the mood; they share some of the same connectives (i.e., ‘then’); they allow for similar patterns of modal subordination. In the light of these affinities, it is not surprising that prominent theories of conditionals—old and new suppositionalisms as well as dynamic theories of conditionals—as well as (...) certain reductive theories of arguments tend to semantically assimilate conditionals and arguments. In this paper, I shall marshall some linguistic evidence as well as some theoretical considerations for thinking that, despite these similarities, arguments and conditionals should be given a different semantics and I shall lay out a framework that can capture at least some of their affinities while accounting for their outstanding differences.

In ‘Reasoning and Regress’ I argued that inferring a conclusion from a set of propositions may simply consist in taking it that the conclusion follows from these propositions—thereby defusing familiar regress arguments. Sinan Dogramaci challenges the generality of this view, on the grounds that sometimes you may draw conclusions from no premisses that you believe. I respond by clarifying a distinction between the premisses of an argument from the reasons your conclusion is based upon. While suppositional reasoning may (...) involve no premisses in the former sense, it does not follow that it does not involve concluding something on the basis of reasons. This allows the view defended in ‘Reasoning and Regress’ to extend to suppositional reasoning. (shrink)

Rodden writes, “How do stories persuade us? How do they ‘move’—and move us? The short answer: by analogies.” Rodden’s claim is a natural first view, also held by others. This chapter considers the extent to which this view is true and helpful in understanding how fictional narratives, taken as wholes, may be argumentative, comparing it to the two principal (though not necessarily exclusive) alternatives that have been proposed: understanding fictional narratives as exhibiting the structure of suppositional argument, or the (...) structure of a kind of transcendental argument. Three key aspects of understanding a fictional narrative as an argument from analogy are identified. First, the argument will be relativistic or depend in an essential way upon the circumstances or intentions of the auditor or author. Second, in view of the first aspect, the argument will be loose and subjective, and accordingly less likely to yield knowledge. Third, the argument will not exhibit a distinctive structure applicable only to fictional narratives. I find that the third, and sometimes the first and second, of these same three aspects apply to understanding fictional narratives as suppositional arguments. I present considerations that point to a way of establishing that some extended fictions exhibit the structure of a kind of transcendental argument that is neither relativistic nor subjective, is knowledge-generating, and is uniquely applicable to fictional narratives. This supports literary cognitivism—the thesis that “literary fiction can be a source of knowledge in a way that depends crucially on its being fictional.”. (shrink)

I object to Markos Valaris’s thesis that reasoning requires a belief that your conclusion follows from your premisses. My counter-examples highlight the important but neglected role of suppositional reasoning in the basis of so much of what we know.

A popular view maintains that supposition is a kind of cognitive mental state, very similar to belief in essential respects. Call this view “cognitivism about supposition”. There are at least three grades of cognitivism, construing supposition as (i) a belief, (ii) belief-like imagination or (iii) a species of belief-like imagination. I shall argue against all three grades of cognitivism and claim that supposition is a sui generis form of imagination essentially dissimilar to belief. Since for good reasons (i) is (...) not supported in the literature, I shall dwell on (ii) and (iii). Without further explanation supposition has been very often merely postulated as being nothing but belief-like imagination—that is, (ii). I shall show that at least two considerations undermine (ii). First, supposition and belief-like imagination are governed by different norms, more precisely the former is freer than the latter and requires minimal or no mental effort. Second, contrary to belief-like imagination, supposition is “cold”, in that it is typically dissociated from emotional reactions. Proponents of (iii) face the pressure of explaining these differences between supposition and belief-like imagination too. I shall argue that they have not sufficiently motivated the claim that supposition is belief-like. In particular they fail to accommodate precisely the dimensions of supposition pertaining to its normativity and emotionality. I shall close with a sketch of a new account of supposition. (shrink)

This paper presents a unifying diagnosis of a number of important problems facing existing models of rational choice under moral uncertainty and proposes a remedy. I argue that the problems of (i) severely limited scope, (ii) intertheoretic comparisons, and (iii) 'swamping’ all stem from the way in which values are assigned to options in decision rules such as Maximisation of Expected Choiceworthiness. By assigning values to options under a given moral theory by asking something like ‘how much do I desire (...) this option, supposing this theory is true?’ rather than ‘how much value does this theory assign to this option?’ these problems can be avoided, while the appealing features of these accounts can be preserved. This amendment provides a role for the preferences, desires, or goals of rational agents that is curiously absent from the existing discussion of what individuals rationally ought to do when they are uncertain about what they morally ought to do.

This dissertation is devoted to empirically contrasting the Suppositional Theory of conditionals, which holds that indicative conditionals serve the purpose of engaging in hypothetical thought, and Inferentialism, which holds that indicative conditionals express reason relations. Throughout a series of experiments, probabilistic and truth-conditional variants of Inferentialism are investigated using new stimulus materials, which manipulate previously overlooked relevance conditions. These studies are some of the first published studies to directly investigate the central claims of Inferentialism empirically. In contrast, the (...) class='Hi'>Suppositional Theory of conditionals has an impressive track record through more than a decade of intensive testing. The evidence for the Suppositional Theory encompasses three sources. Firstly, direct investigations of the probability of indicative conditionals, which substantiate “the Equation” (P(if A, then C) = P(C|A)). Secondly, the pattern of results known as “the defective truth table” effect, which corroborates the de Finetti truth table. And thirdly, indirect evidence from the uncertain and-to-if inference task. Through four studies each of these sources of evidence are scrutinized anew under the application of novel stimulus materials that factorially combine all permutations of prior and relevance levels of two conjoined sentences. The results indicate that the Equation only holds under positive relevance (P(C|A) – P(C|¬A) > 0) for indicative conditionals. In the case of irrelevance (P(C|A) – P(C|¬A) = 0), or negative relevance (P(C|A) – P(C|¬A) < 0), the strong relationship between P(if A, then C) and P(C|A) is disrupted. This finding suggests that participants tend to view natural language conditionals as defective under irrelevance and negative relevance (Chapter 2). Furthermore, most of the participants turn out only to be probabilistically coherent above chance levels for the uncertain and-to-if inference in the positive relevance condition, when applying the Equation (Chapter 3). Finally, the results on the truth table task indicate that the de Finetti truth table is at most descriptive for about a third of the participants (Chapter 4). Conversely, strong evidence for a probabilistic implementation of Inferentialism could be obtained from assessments of P(if A, then C) across relevance levels (Chapter 2) and the participants’ performance on the uncertain-and-to-if inference task (Chapter 3). Yet the results from the truth table task suggest that these findings could not be extended to truth-conditional Inferentialism (Chapter 4). On the contrary, strong dissociations could be found between the presence of an effect of the reason relation reading on the probability and acceptability evaluations of indicative conditionals (and connate sentences), and the lack of an effect of the reason relation reading on the truth evaluation of the same sentences. A bird’s eye view on these surprising results is taken in the final chapter and it is discussed which perspectives these results open up for future research. (shrink)

ABSTRACT Drawing upon cross-sectional research with pre- and in-service police officers in the U.K. (N = 571), this paper reports on the moral reasoning strategies favored by the respondents in dealing with bespoke work-related moral quandaries specific to the professional practice of policing. The dominant form of moral reasoning in dealing with those dilemmas was deontological (rule-based). The second most frequently selected reasoning strategy was virtue ethical. Further analysis of the police research data indicated that those with an undergraduate degree (...) were significantly more likely to adopt virtue ethical and consequentialist-utilitarian reasoning strategies than those who did not have an undergraduate degree.

I first support Alec Fisher's thesis that premises and conclusions in arguments can be unasserted first by arguing in its favor that only it preserves our intuition that it is at least possible that two arguments share the same premises and the same conclusion although not everything that is asserted in the one is also asserted in the other and second by answering two objections that might be raised against it. I then draw from Professor Fisher's thesis the consequence that (...) in suppositional arguments the falsity (or unacceptability) of a supposition does not tell unfavorably in the evaluation of the argument, because the falsity (or unacceptability) of a (nonredundant) premise counts against an argument if and only if that premise is asserted. Finally, I observe that, despite the fact that they are neither expressed nor even alluded to, implicit assumptions in arguments are always asserted, unless the conclusion, but none of the explicit premisses, is unasserted. Hence, apart from an exceptional case of the kind just mentioned, the falsity (or unacceptability) of implicit assumptions always counts against an argument. (shrink)

This book provides a comprehensive account of Kant’s development from the 1755/56 metaphysics to the cosmological antinomy of 1781. With the Theory of the Heavens (1755) and the Physical Monadology (1756), the young Kant had presented an ambitious approach to physical cosmology based on an atomistic theory of matter, which contributed to the foundations of an all-encompassing system of metaphysics. Why did he abandon this system in favor of his critical view that cosmology runs into an antinomy, according to the (...) Critique of Pure Reason (CPR)? This book answers this question by focusing on Kant’s methodology and the internal problems of his 1755/56 theory of nature. A decisive role for Kant’s critical turn plays the argument from incongruent counterparts (1768), which drew much attention among philosophers of science, though not sufficiently in Kant research. Furthermore, the book analyses the genesis of the cosmological antinomy in the 1770s, the logical structure of the antinomy in the CPR, its relation to transcendental idealism, as explained in the “experiment of pure reason” (1787), and its role for the teleology of human reason. The book is addressed to Kant scholars, philosophers of science, and students of Kant’s philosophy. (shrink)

[Marilyn McCord Adams] In this paper I begin with Aristotle's Categories and with his apparent forwarding of primary substances as metaphysically special because somehow fundamental. I then consider how medieval reflection on Aristotelian change led medieval Aristotelians to analyses of primary substances that called into question how and whether they are metaphysically special. Next, I turn to a parallel issue about supposits, which Boethius seems in effect to identify with primary substances, and how theological cases-the doctrines of the Trinity, the (...) Incarnation, and of the human soul's separate survival between death and resurrection-call into question how and to what extent supposits are metaphysically special. I conclude with some reflections on various senses of being metaphysically special and how they pertain to primary substances and supposits. /// [Richard Cross] Scotus's belief that any created substance can depend on the divine essence and/or divine persons as a subject requires him to abandon the plausible Aristotelian principle that there is no merely relational change. I argue that Scotus's various counterexamples to the principle can be rebutted. For reasons related to those that arise in Scotus's failed attempt to refute the principle, the principle also entails that properties cannot be universals. (shrink)

In Constructing the World, Chalmers observes that our knowledge exceeds the core evidence provided by our senses and introspection. Thus, on the basis of core evidence, one also can know (S) that water covers the majority of the Earth. This knowledge, Chalmers suggests, requires a great deal of apriori knowledge. Chalmers argues that even if one suspends belief in one’s core evidence, one can nevertheless reason from a description of this evidence to an ordinary claim such as S. Chalmers concludes (...) that the ordinary claim must be apriori entailed by a description of the core evidence. However, I propose that careful thinking about belief suspension reveals that empirical information can contaminate the reasoning from the core evidence to the ordinary claim S, even if belief in the core evidence is suspended. One result is that empiricists and externalists may freely appeal to thought experiments without having to concede that there are substantive apriori truths. (shrink)

In his Liberalism without Perfection, Jonathan Quong argues for internal conception of political liberalism which goal is to show that a liberal well-ordered society is internally coherent ideal and that citizens who would be raised in such society could endorse and support their own liberal institutions and principles if those institutions and principles are justified in particular way These institutions should be justified by particular conception of public reason which main feature is that overlapping consensus is the first stage of (...) its justificatory structure. So, public reasoning of citizens in well-ordered society should be based solely on values and ideas inherent to liberal conception of justice - freedom, equality, fair system of cooperation and burdens of judgment. Another important feature of Quong?s conception of public reason concerns its scope. Quong argues for a wide scope of public reason which demands that all coercive or binding laws or public policies should be justified on basis of these values alone. Thus, reasonable citizens in well-ordered society by definition accord deliberative priority to public reasons over their other comprehensive or nonpublic beliefs whenever they exercise their collective political power over one another. The problem I raise in this paper is that it is very likely that in well-ordered society there will be a group of citizens that will not accord full deliberative priority to political values, especially not at all levels of political deliberation. On certain issues they will like to see their particular values being realized through common political institutions. If our political theory excludes this group from justificatory constituency on this particular issue or categorize them as unreasonable it can easily undermine their general adherence to liberal conception of justice and endanger stability of well-ordered society. Thus, my point is that we need a further development of political liberalism to solve such problems not as a part of non-ideal theory but as a part of its ideal of well-ordered society. nema. (shrink)
