In the World Library of Psychologists series, international experts themselves present career-long collections of what they judge to be their finest pieces - extracts from books, key articles, salient research findings, and their major theoretical and practical contributions. Jonathan St B T Evans is amongst the foremost cognitive psychologists of his generation, having been influential in spearheading developments in the psychological study of reasoning from its very beginnings in the 1970s up to the present day. This volume of self-selected papers (...) recognises Professor Evan's major contribution to the psychological study of thinking and reasoning by bringing together his most influential and important works. Early selections in the book focus upon experimental studies of reasoning - matching bias in the Wason selection task, belief bias in syllogistic reasoning, and also seminal work on the understanding of conditional statements. The later selections include Evans' work on more general forms of dual process and dual system theory, and his recent account of two minds in one brain. The volume also contains chapters which highlight Evans' contribution to the topic of human rationality, and also his influence on the development of the "new paradigm" in the psychology of reasoning. The key developments in the psychology of reasoning are paralleled by those in Evans's own intellectual history, and the book will therefore make essential reading for all researchers in the psychology of reasoning, and a wider audience of graduate and upper-level undergraduate students with an interest in reasoning and/or dual process theory.

I reason: (1) For any x, if I knew that A contained x, then the odds are even that B contains either 2x or x/2, so the expected amount in B would be 5x/4. So (2) for all x, if I knew that A contained x, I would have an expected gain in switching to B. So (3) I should switch to B. But this seems clearly wrong, as my information about A and B is symmetrical.

Stars are conspicuously absent from reflections on natural kinds and scientific classifications, with gold, tiger, jade, and water getting all the philosophical attention. This is too bad for, as this paper will demonstrate, interesting philosophical lessons can be drawn from stellar taxonomy as regards two central, on-going debates about natural kinds, to wit, the monism/pluralism debate and the realism/antirealism debate. I’ll show in particular that stellar kinds will not please the essentialist monist, nor for that matter will it please the (...) pluralist embracing promiscuous realism à la Dupré. (shrink)

: A central claim of Longino's contextual empiricism is that scientific inquiry, even when "properly conducted", lacks the capacity to screen out the influence of contextual values on its results. I'll show first that Longino's attack against the epistemic integrity of science suffers from fatal empirical weaknesses. Second I'll explain why Longino's practical proposition for suppressing biases in science, drawn from her contextual empiricism, is too demanding and, therefore, unable to serve its purpose. Finally, drawing on Bourdieu's sociological analysis of (...) scientific communities, I'll sketch an alternative view of scientific practice reconciling a thoroughly social view of science (such as Longino's) with a defense of its epistemic integrity.

This essay develops a form of scientific pluralism that captures essential features of contemporary scientific practice largely ignored by the various forms of scientific pluralism currently discussed by philosophers. My starting point is Hacking's concept of style of scientific reasoning. I extend Hacking's thesis by proposing the process of “ontological enrichment” to grasp how the objects created by a style articulate with the common objects of scientific inquiry. The result is “foliated pluralism,” which puts to the fore the transdisciplinary and (...) cumulative ways of proceeding in science, as well as the historical dimension of the genesis of scientific objects.

The unpredictability of the development and results of a research program is often invoked in favor of a free, desinterested science that would be led mainly by scientific curiosity, in contrast with a use-inspired science led by definite practical expectations. This paper will challenge a crucial but underexamined assumption in this line of defense of scientific freedom, namely that a free science is the best system of science to generate unexpected results. We will propose conditions favoring the occurrence of unexpected (...) facts in the course of a scientific investigation and then establish that use-inspired science actually scores better in this area.

2011 Reprint of 1943 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition Software. "St. Thomas Aquinas" is enriched by the author's unique ability to see the world through the saint's eyes, a fresh and animated view that shows us Aquinas as no other biography has. Acclaimed as the best book ever written on Aquinas by such outstanding Thomists as Jacques Maritain, Etienne Gilson, and Anton Pegis, this brilliant biography will completely capture the reader and leave him (...) desirous of reading Aquinas' own monumental work.

My main aim in this paper is to show that influential antireductionist arguments such as Fodor's, Kitcher's, and Dupré's state stronger conclusions than they actually succeed in establishing. By putting to the fore the role of metaphysical presuppositions in these arguments, I argue that they are convincing only as 'temporally qualified argument', and not as 'generally valid ones'. I also challenge the validity of the strategy consisting in drawing metaphysical lessons from the failure of reductionist programmes. What most of these (...) antireductionist standpoints have in common is a pretension to methodological imports. I conclude by explaining why, in order to remain relevant for scientific practice, antireductionist arguments should stay clear of metaphysics, for the latter, I argue, does not mix well with a taste for methodological prescriptions.

Nancy Cartwright's charge against horizontal reductionism leads to a claim about how the world is, namely "dappled." By proposing a simple thought-experiment, I show that Cartwright's division of the world into "nomological" machines and "messy" systems for which no law applies is meaningless. The thought-experiment shows that for a system, having the property of being a nomological machine depends on what kind of questions you ask about it. No metaphysical conclusion about the world being unruly or not can be drawn (...) from a division that is question-dependent. Moreover, I argue that this predicament undermines Cartwright's attempt to provide an illustration of how bad metaphysics of science translates into bad scientific methodologies and policies.

While not taking St. Anselm’s ontological argument in the Proslogion to be valid, this paper shows that the dismissal of the thesis by both St. Thomas Aquinas and Kant does less than justice to St. Anselm’s text. In Chapter II of the Proslogion Anselm defines God as ‘something than which nothing greater can be thought’, claiming that this notion ‘exists in the mind’. The question is does its subject, God, exist ‘in re’. Can one proceed from the mental existence to (...) real existence given that to exist in re is greater than to exist notionally? This paper sets out several of Anselm’s premises from which he concludes that the notional existence of God defined by Anselm entails God’s actual existence, Aquinas dismissed Anselm’s arguments – possibly not having Anselm’s full text at hand. Anselm maintains that if ‘something than which nothing greater can be thought’ can be conceived, then to deny its existence in re constitutes a self-contradiction. The present paper examines in detail the elements of which Anselm’s elegant arguments are composed: q.v. Reference is made to Anselm’s Reply to Gaunilo, and to Anselm’s ontology set out in Monologion. Much, for the modern reader, turns on the topical logic of ‘perfection’ and of ‘greatness’. Again: much turns on the Kantian question ‘Is existence a predicate?’ And on the question: what kinds of things can be the subject of predicates? The comparison which Anselm is making between real and conceptual existence is not like any other comparison. This may be the flaw in his arguments. (shrink)

Given the importance of the issue of scientific objectivity in our democratic societies and the significant development of citizen science, it is crucial to investigate how citizen science may either undermine or foster scientific objectivity. This paper identifies a variety of epistemic risks and benefits that participation of lay citizens in scientific inquiries may bring. It also discusses concrete actions and pending issues that should be addressed in order to foster objectivity in citizen science programs.

Thomas Aquinas is generally acknowledged to be the greatest theologian of the Middle Ages and his masterpiece, 'Summa Theologica', provides a complete and authoritative statement of medieval economic thought that has remained the official Catholic view right up to the present time.St Thomas had a decisive influence on economic thought in at least three broad areas: the theory of private property, the theory of the just price and the doctrine of usury. St Thomas's great contribution to economic thought, as to (...) theology, moral philosophy, and politics, lies in his emphasis on ratiocination on the Greek ideal of accepting nothing unless good reasons can be given for it.

The building of a global model of carcinogenesis is one of modern biology’s greatest challenges. The traditional somatic mutation theory is now supplemented by a new approach, called the Tissue Organization Field Theory. According to TOFT, the original source of cancer is loss of tissue organization rather than genetic mutations. In this paper, we study the argumentative strategy used by the advocates of TOFT to impose their view. In particular, we criticize their claim of incompatibility used to justify the necessity (...) to definitively reject SMT. First, we note that since it is difficult to build a non-ambiguous experimental demonstration of the superiority of TOFT, its partisans add epistemological and metaphysical arguments to the debate. This argumentative strategy allows them to defend the necessity of a paradigm shift, with TOFT superseding SMT. To do so, they introduce a notion of incompatibility, which they actually use as the Kuhnian notion of incommensurability. To justify this so-called incompatibility between the two theories of cancer, they move the debate to a metaphysical ground by assimilating the controversy to a fundamental opposition between reductionism and organicism. We show here that this argumentative strategy is specious, because it does not demonstrate clearly that TOFT is an organicist theory. Since it shares with SMT its vocabulary, its ontology and its methodology, it appears that a claim of incompatibility based on this metaphysical plan is not fully justified in the present state of the debate. We conclude that it is more cogent to argue that the two theories are compatible, both biologically and metaphysically. We propose to consider that TOFT and SMT describe two distinct and compatible causal pathways to carcinogenesis. This view is coherent with the existence of integrative approaches, and suggests that they have a higher epistemic value than the two theories taken separately. (shrink)

The strict-tolerant approach to paradox promises to erect theories of naïve truth and tolerant vagueness on the firm bedrock of classical logic. We assess the extent to which this claim is founded. Building on some results by Girard we show that the usual proof-theoretic formulation of propositional ST in terms of the classical sequent calculus without primitive Cut is incomplete with respect to ST-valid metainferences, and exhibit a complete calculus for the same class of metainferences. We also argue that the (...) latter calculus, far from coinciding with classical logic, is a close kin of Priest’s LP. (shrink)

St. John of the Cross was aware of the fact that his mysticism resisted prosaic, discursive representation; however, most contemporary scholars have overlooked this radical component of his work. First, I trace the major philosophical influences on John’s work: Medieval Neoplatonism and Scholasticism. Second, by drawing on the Barthesian-Foucauldian concept of the author function, I demonstrate that the Mystical Doctor saw his poetry as free-standing, inexhaustible by even his own efforts to systematize key aspects of his poetry—an insurmountable task, which (...) he had to be compelled to compile and publish by the nuns he guided in spiritual direction.

In this final edition of his classic study of St. Thomas Aquinas, Etienne Gilson presents the sweeping range and organic unity of Thomistic philosophical thought. The philosophical thinking of Aquinas is the result of reason being challenged to relate to many theological conceptions of the Christian tradition. Gilson carefully reviews how Aquinas grapples with the relation itself of faith and reason and continuing through the existence and nature of God and His creation, the world and its creatures, especially human beings (...) with their power of intellect, will, and moral life. He concludes this study by discussing the life of people in society, along with their purpose and final destiny. Gilson demonstrates that Aquinas drew from a wide spectrum of sources in the development of his thought-from the speculations of the ancient Greeks such as Aristotle, to the Arabic and Jewish philosophers of his time, as well as from Christian writers and scripture. The Christian Philosophy of St. Thomas Aquinas offers students of philosophy and medieval studies an insightful introduction to the thought of Aquinas and the Scholastic philosophy of the Middles Ages, insights that are still revelant for today.

In the _Proslogion_, St. Anselm presents a philosophical argument for the existence of God. Anselm's proof, known since the time of Kant as the ontological argument for the existence of God, has played an important role in the history of philosophy and has been incorporated in various forms into the systems of Descartes, Leibniz, Hegel, and others. Included in this edition of the_ Proslogion _are Gaunilo's "A Reply on Behalf of the Fool" and St. Anselm's "The Author's Reply to Gaunilo." (...) All three works are in the original Latin with English translation on facing pages. Professor Charlesworth's introduction provides a helpful discussion of the context of the _Proslogion_ in the theological tradition and in Anselm's own thought and writing. (shrink)

In the article, the main lines of the research and educational cooperation of the linguists of the Bashkir State University and the St. Cyril and St. Methodius University of Veliko Turnovo are considered. The prospects of these contacts are determined by capabilities of joint development of the long-term research programs in comparative linguistics, sociolinguistics, cognitive linguistics, which can be implement as collective monographs, Ph.D. theses, textbooks of the Russian and the Bulgarian languages, dictionaries (including the multilingual dictionaries). A program of (...) the double diplomas in the specialized training of undergraduates ‘Applied Slavic philology (translation study)‘ as a new form of the cooperation is also considered. (shrink)

In May AD 597, 1400 years ago, a young Sicilian monk called Augustine disembarked at Ebbsfleet, in south-east Kent, an event which was to change the development of Christianity and culture in this country for all time. It had taken St. Augustine and his 20 or 30 companions a year to travel from Rome, where they had been specially selected by Pope Gregory the Great to convert Anglo-Saxon Britain and to restore contact with the early Celtic Church. This book tells (...) the story of St. Augustine's journey, his arrival, his seven-year missionary activity in Kent and anticipates the full impact of those vital years on English life. Supported by relevant historical contexts and fascinating documentary evidence, a bibliography, notes and photographs, St. Augustine of Canterbury offers us today a celebratory glimpse of one of our history's most significant moments.

La transformation du mode de production des connaissances scientifiques va de pair avec une évolution significative des attentes de la société vis-à-vis des sciences, et soulève pour le philosophe de nouvelles questions : qu’est-ce qui est vraiment nouveau dans le régime actuel de production des connaissances ? Quel rôle et quelle responsabilité pour le chercheur face à la demande croissante d’expertise scientifique ? Quelle attitude avoir face à des avancées technologiques touchant à la nature même de l’Homme ? Le citoyen (...) doit-il être davantage impliqué dans le choix des grandes priorités de la recherche ? Cet ouvrage offre une sélection variée et accessible de travaux actuels en philosophie des sciences explorant les facettes multiples des relations entre science et société. (shrink)

As noticed recently by Winsberg (2003), how computer models and simulations get their epistemic credentials remains in need of epistemological scrutiny. My aim in this paper is to contribute to fill this gap by discussing underappreciated features of simulations (such as “path-dependency” and plasticity) which, I’ll argue, affect their validation. The focus will be on composite modeling of complex real-world systems in astrophysics and cosmology. The analysis leads to a reassessment of the epistemic goals actually achieved by this kind of (...) modeling: I’ll show in particular that its realistic ambition and the possibility of empirical confirmation pull in opposite directions.
