Rationalism

How should we understand good philosophical inquiry? Ernest Sosa has argued that the key to answering this question lies with virtue-based epistemology. According to virtue-based epistemology, competences are prior to epistemic justification. More precisely, a subject is justified in having some type of belief only because she could have a belief of that type by exercising her competences. Virtue epistemology is well positioned to explain why, in forming false philosophical beliefs, agents are often less rational than it is possible to (...) be. False philosophical beliefs are often unjustified—and the agent is thereby less rational for having them—precisely because these beliefs could not be formed by exercising competences. But, virtue epistemology is not well positioned to explain why, in failing to form some true philosophical beliefs, agents are less rational than it is possible to be. In cases where agents fall short by failing to believe philosophical truths, the problem is not that they believe things they shouldn’t, but that they lack beliefs they ought to have. We argue that Timothy Williamson's recent critique of the a priori/a posteriori distinction falls prey to similar problem cases. Williamson fails to see that a type of belief might be a priori justified if and only if, even without any special confirming experiences, agents fall short by failing to have this type of belief. We conclude that there are types of beliefs that are deeply a priori justified for any agent regardless of what epistemic competences the agent has. However, we also point out that this view has a problem of its own: it appears to make the acquisition of a priori knowledge too easy. We end by suggesting that a move back towards virtue-based epistemology is necessary. But in order for this move to be effective, epistemic competences will have to be understood very differently than in the reliabilist tradition. (shrink)

Following Avicenna, many Muslim philosophers and logicians have identified ‘intellectual universal’ (kullī ʿaqlī) with the very mental concept dependent on mind. Apart from the controversies about Platonic Forms, they argue that they cannot be the very universals in logic. Accordingly, Mullā Ṣadrā’s commentators have interpreted his view on intellectual universal in the Avicennian framework. In this interpretation, Mullā Ṣadrā has embraced Avicenna’s explanation about mind-dependent universal concepts; however, he has modified some details of the issue as per his theory of (...) the primacy of existence and Plato’s theory of Forms. Having explained Sabzawārī and Ṭabāṭabāʼī’s interpretation of Mullā Ṣadrā’s view in his article, the author goes to propose a different interpretation according to which intellectual universals are identical with Platonic Forms, rather than the mind-dependent universal concepts. This Platonic interpretation is supported by three sets of evidences from Mullā Ṣadrā’s own texts. It also shows how Mullā Ṣadrā has answered Avicenna’s objection about the use of Platonic universal in logic. (shrink)

This article is concerned with some of the criteria which Hegel believes apply to a scientific treatment of logic. I briefly address criteria which I take Hegel to inherit from German rationalism before focusing on two fairly idiosyncratic criteria: the requirement that a science of logic exhibit a circular structure and that it begin with the concept of pure being. I offer an explanation of these criteria which understands them as motivated by anti-sceptical concerns, before arguing that Hegel’s mature treatment (...) of the latter criterion is problematically ambiguous.

The topic of my paper is the virtual controversy between Leibniz and Lockeover concepts and ideas. At the end of the 17th century John Locke made a crucial contribution to semantics and philosophy: An Essay Concerning Human Understanding. The work represents a decisive turning point for the discussion about ideas and innatism. Indeed, Locke’s aim was to dismantle the Cartesian theory according to which ideas are innate in our soul. Against this onto-epistemological thesis, Locke maintains that all our knowledge starts (...) off with experience: ideas are mental representations depending on subjects’ sensual experiences and reflection skills. Some years later, in his notes on Locke’s Essay, Leibniz writes that Locke dealt with a fundamental topic: human understanding and the limits of human knowledge (NE p. 4). All we can find out about the world is determined by answering the question about what we can know; nonetheless, Leibniz argues in favor of innate ideas. My thesis is that in his opinion Locke’s empiricism can be conciliated with the assumption that there are innate ideas. (shrink)

Discovering laws of nature was a way to worship a law-giving God, during the Scientific Revolution. So why should we consider it worthwhile now, in our own more secularized science? For historical perspective, I examine two competing early modern theological traditions that related laws of nature to different divine attributes, and their secular legacy in views ranging from Kant and Nietzsche to Humean and ‘governing’ accounts in recent analytic metaphysics. Tracing these branching offshoots of ethically charged God-concepts sheds light on (...) how our ethical ideals and ideas of natural order can still be valuably integrated. Early modern intellectualists valued the law-governed order of nature as a sign of divine Reason. In turn, Reason traditionally ascribed to God has now been partly reclaimed for humans, reframing the value of natural order anthropocentrically, in terms of the value of our own intelligence. Alternatively, Reason may be reclaimed for nature itself, as in an ‘objective’ idealism or metaphysical rationalism. However, beyond divine Reason, an influential voluntarist tradition in theology stressed a connection between laws of nature and God’s Power or free Will. Tracking how divine Power has been reinvested in human beings provides a broader context for instrumentalism and related lineages of empiricism. But secularization can also transfer Power from God to the impersonal natural world. In this light, current scientific interest in lawlike order may also reflect the inherent value of brute necessity or inhuman causal power in nature: this is a deeper way to reject anthropocentrism and to show our respect for the environment.

The idea of a “first principle” looms large in Fichte’s thought, and its first real appearance is in his “Aphorisms on Religion and Deism”, which has received little attention. I begin this paper by providing some context on that piece, and then developing a reconstruction of the position presented within it. Next, I establish that Fichte’s views at the time of writing, and for some years prior, are those of the “deist,” and clarify why he sensed he had to leave (...) this stance represented in the “Aphorisms” behind. I conclude that understanding Fichte’s shift away from “deism,” a species of what he would eventually call “dogmatism,” can also help us understand Fichte’s critique of the latter kind of thinking and so shed light on Fichte’s better-known views; and I emphasize that Fichte’s transition from a strict rationalism to a form of Kantianism may be of interest not only to scholarship on Fichte and the period, but likewise to work on rationalism in contemporary metaphysics. Finally, in an appendix I supplement the paper with a first English translation of the entire text of the “Aphorisms,” complete with annotations. (shrink)

Some truths about color are knowable a priori. For example, it is knowable a priori that redness is not identical to the property of being square. This extremely modest and plausible claim has significant philosophical implications, or so I shall argue. First, I show that this claim entails the falsity of standard forms of color functionalism, the view that our color concepts are functional concepts that pick out their referents by way of functional descriptions that make reference to the subjective (...) responses of perceivers. I then argue that, while some sophisticated forms of color functionalism can accommodate the a priori knowability of a truth like “redness is not identical to squareness,” they can only do so by abandoning color realism, the thesis that colors are instantiated by external material objects. In practice, color functionalists are almost invariably color realists. Thus, given extremely modest assumptions concerning what can be known a priori about color, we should conclude that color functionalism, at least in its typical realist form, is false. (shrink)

Nicholas Rescher presents an original pragmatic defense of the issue of objectivity. Rescher employs reasoned argumentation in restoring objectivity to its place of prominence and utility within social and philosophical discourse. By tracing the source of objectivity back to the very core of rationality itself, Rescher locates objectivity's reason for being deep in our nature as rational animals. His project rehabilitates the case for objectivity by subjecting relativistic and negativistic thinking to close critical scrutiny, revealing the flaws and fallacies at (...) work in the deliberations of those who dismiss objectivity as obsolete and untenable. Rescher takes to task the cultural relativism of contemporary social science and social theory, as well as that of liberalistic political correctness and the postmodern aversion to the normative. In holding such relativistic thinking up to the light of rational argument, he demonstrates that a rejection of objectivity is in fact unreasonable. Rescher further reveals that a relativistic apathy to truth and rightness actually destroys, in effect, the very conception it presumably elucidates. (shrink)

We aim to compile some means for a rational reconstruction of a named part of the start-over of Baruch (Benedictus) de Spinoza's metaphysics in 'de deo' (which is 'pars prima' of the 'ethica, ordine geometrico demonstrata' ) in terms of 1st order model theory. In so far, as our approach will be judged successful, it may, besides providing some help in understanding Spinoza, also contribute to the discussion of some or other philosophical evergreen, e.g. 'ontological commitment'. For this text we (...) assume the reader familiar with 'de deo' as well as with some basic concepts and results of 1st order model theory. Before we start reconstruction, we will first revisit shortly the concept of 'attributum' (definitio IV) in it's setting in 'de deo' , next scan for formalizable aspects of 'in suo genere finita' ('de deo', definitio II), subsequently list the model theoretic constructs we will make use of. Then we begin reconstruction by stating "coordinative definitions" for the notions of 'attribute (of a substance)', 'modus (as conceived via an attribute)' and 'substance (as conceived via an attribute)', reasoning shortly for each of them. The "coordinative definitions", we will arrive at, must not be understood as literal translations of Spinoza's concepts - of course, there can't be such a thing as a literal translation - they are meant as formal analoga of these concepts, mapping some logical structure. But even with this caveat they may seem strange to the reader at this stage of discussion. Additional justification for them then should be found in our endeavour, to map some argumentation of Spinoza's proofs of some of his propositions from this starting point. -/- [ Version 1 of this paper originated from 2020-03-14.

Le théisme est la position métaphysique au cœur des religions monothéistes : il est l’affirmation qu’il existe un Dieu omniscient, omnipotent, parfaitement bon et créateur. Penser l’objet de ces croyances, à savoir Dieu, suppose donc une étude des catégories métaphysiques nécessaires à l’explicitation du théisme. Loin de tout rationalisme étroit et de toute exaltation mystique, le présent ouvrage mobilise les outils de la philosophie contemporaine afin de mettre au jour les choix théoriques qui sont requis pour concevoir un Dieu compris (...) comme l’être ayant toutes les perfections. Les questions du réalisme, de la vérité, du premier principe, du possible et du nécessaire sont étudiées aussi bien à partir du contenu des croyances religieuses que de la métaphysique analytique contemporaine, en réponse aux critiques de Kant et de Heidegger. Car avant même de s’interroger sur l’existence ou sur l’inexistence d’un tel Dieu, ou encore de discuter de la rationalité ou de l’irrationalité des croyances religieuses, ce sont les outils conceptuels pour penser un Dieu qu’il nous faut examiner philosophiquement.

In the accepted view, the basic disposition of believers is one of absolute obedience, humility, and lack of critique, doubt, or, indeed, defiance of God. Only through such a disposition do believers convey their absolute faith and establish the appropriate hierarchy between God and humans. This article challenges this view and argues that, in mainstream rabbinic tradition, the believer is not required to renounce his or her moral autonomy and certainly not his or her understanding of God and the world. (...) Indeed, faith rests on such understanding; moreover, human autonomy is the mechanism through which humans convey God’s goodness and perfection. Their questions and criticism are part of a persistent effort to close the evident gap between their assumptions about God’s goodness and the flawed imperfect reality. The analysis focuses on rabbinic tradition but its implications go beyond it, presenting a model of a life of faith that compels subjects, as believers, to preserve their constitutive foundations as rational autonomous creatures.

On peut inscrire les travaux de Engel dans le sillage rationaliste des Pères de la philosophie analytique, mais après le tournant naturaliste opéré par Quine. Ce sont les diverses bonnes raisons, exposées de manière non systématique par Engel, d’associer naturalisme et rationalisme que je souhaite présenter tout en cherchant à identifier la difficulté constitutive de ce programme qui ne reçoit pas de solution complète: la normativité épistémique ne semble ni éliminable, ni correctement intégrée à ce programme.

he burgeoning science of ethics has produced a trend toward pessimism. Ordinary moral thought and action, we're told, are profoundly influenced by arbitrary factors and ultimately driven by unreasoned feelings. This book counters the current orthodoxy on its own terms by carefully engaging with the empirical literature. The resulting view, optimistic rationalism, shows the pervasive role played by reason our moral minds, and ultimately defuses sweeping debunking arguments in ethics. The science does suggest that moral knowledge and virtue don't come (...) easily. However, despite the heavy influence of automatic and unconscious processes that have been shaped by evolutionary pressures, we needn't reject ordinary moral psychology as fundamentally flawed or in need of serious repair. Reason can be corrupted in ethics just as in other domains, but a special pessimism about morality in particular is unwarranted. Moral judgment and motivation are fundamentally rational enterprises not beholden to the passions. (shrink)

Self-knowledge is the cognitive ability of the agent to know his or her own mental states. There are several types of mental states, and there is a method for the knowledge of each type. The focus of this dissertation is on the knowledge of one‘s own beliefs. With this goal in mind, we present the empiricist and the rationalist approaches to the knowledge of one‘s own beliefs. Empiricist theories of self-knowledge proposes introspection as the method for the knowledge of one‘s (...) own beliefs. However, there are issues related to the phenomenology of belief – what it is like to believe that p? The best rationalist theories of self-knowledge proposes that an agent ―look outwards to constitute her own mind and her own belief. Our final question is about the relationship between knowledge of one‘s beliefs and rationality. Burge (2013) requires that, in order to be rational, one must have self-knowledge. We argue that the kind of rationality specified by Burge is too demanding. As agents in the realm of common life, we have incomplete understanding of our own doxastic mental states, but that is not a problem for the knowledge of our own beliefs as dispositions, since they does not come from rational deliberation; nevertheless, we are responsible and our beliefs as commitments. Both kinds of belief can be known by the transparency method. We conclude claiming that the transparency method is enough for the self-knowledge of doxastic mental state and ensuring the rationality of the agent. (shrink)

La superación del racionalismo y del relativismo no ha podido gestarse con fecundidad. Posiblemente porque el absolutismo racionalista -que salva la razón a costa de anular la vida- y el relativismo -que salva la vida negando la razón- se han desplazado en una dimensión única que imposibilitaba la insumisión a ese dilema vertebrado por una concepción absolutista de la verdad y que nos constriñe a instalarnos en alguno de sus términos. La constante aparición del nexo entre los problemas antropológicos más (...) relevantes y la crítica de la metafísica exigen que la postmodernidad sea reubicada en un contexto que supere su inserción en un escenario que tengan por trasfondo únicamente a la modernidad. En otras palabras, hay una necesidad de trascender el binomio modernidad-postmodernidad. De esta manera, se considera que la tradición realista debe aparecer en escena en abierto diálogo crítico con los posicionamientos cronológicamente posteriores. Por lo que se refiere a la estructura de la presente obra hay que decir que sus once capítulos se distribuyen en tres partes. La primera de ellas intenta desentrañar y ordenar los elementos que generan el estado de cierta postración en el que se halla el pensamiento crítico-especulativo. En la segunda parte se procede a recorrer cada una de las derivaciones más relevantes de la desconfianza de la razón hacia sí misma. Por último, la tercera parte intenta poner de manifiesto qué posibilidades quedan al pensamiento de la constitución de lo nuevo tanto en el ámbito filosófico como en el pedagógico. Los modernos creyeron que al ser humano cabe forjarlo por el poder de la razón; los postmodernos estiman que no debe hacerse. ¿Es sólo por casualidad que hay una coincidencia fundamental entre ambas perspectivas? En el fondo, uno y otro convienen que la razón lo puede todo; modernos y postmodernos coinciden en la creencia del poder ilimitado de la razón y, como consecuencia de ello, creen en la posibilidad de la ilimitada y absoluta transformación de la totalidad de lo real. Y ello, aunque lo hagan en sentido diverso y lo valoren de manera inversa. Cabe, pues, pensar que, en el fondo, no hay más que una remodelación monótona de lo mismo. Las repercusiones del nihilismo, del relativismo moral, de la crisis antropológica postmoderna, de los nacionalismos identitarios, del pluralismo religioso, de la política democrática y de los tópicos del relativismo cultural son, pues, abordados –y enhebrados- en la Crítica de la razón moderna. Por ello, esta obra supone una seria y muy completa contribución al esclarecimiento de la vertebración del pensamiento y las prácticas culturales vigentes. Además, es una obra imprescindible en la biblioteca de profesores y de estudiantes de las facultades de Educación, Filosofía, Historia, Teología, Ciencias Políticas y Sociología. Y también resulta relevante para todas aquellas personas que se afanan por comprender los fundamentos teóricos de las perspectivas sociales y humanísticas actuales así como sus derivaciones y praxis concretas.

For well over a century the dominant narrative covering the major thinkers and themes of early modern British philosophy has been that of “British Empiricism”, within which the great triumvirate of Locke-Berkeley-Hume are taken to be the dominant figures. Although it is now common to question this schema as a way of analyzing and understanding the period in question, it continues to command considerable authority and acceptance. (One likely reason for this is that no credible or plausible alternatives structures or (...) schemas of analysis have suggested themselves.) Be this as it may, the analysis of the rival systems of Clarke, Berkeley and Hume makes clear that this narrative, however deeply entrenched it may be, is wholly misleading and both distorts and obscures key themes and figures in the period in question.

In this article I challenge the current view that Hume is a naturalist as well as a sceptic. I hold he is a peculiar kind of rationalist. I argue that his position is best viewed as a philosophical approach designed to accommodate the tendencies of human nature. This task is carried out by means of a second order reflection, which turns out to be based upon reason of a non demonstrative kind. It is brought into clear focus when the mind (...) discovers a conflict between two tendencies. In section one, I highlight this kind of conflict in Hume’s account of causal inference. In section two I unfold the conflict that can be found in his account of our belief in the continued and independent existence of objects. In section three I show how it is possible to reconcile our tendencies. I maintain that this reconciliation is effected by means of second order, reason-based arguments. In section four, I examine the status of Hume's scepticism in the light of the preceding account and conclude that his standpoint is not sceptical at all. (shrink)

This paper will explore some of the issues and arguments and offer some critical reflection on the ideas and ways that people have proposed to overcome or uphold the dilemma or conflict between the existence of the God of classical theism and evil and the consequence of evil - suffering. I seek explanation of the plain fact of evil and suffering but I do not seek it in the arrogant belief that I can explain evil away. My Christian faith is (...) not meant to provide complete answers and understanding to all life’s vexing questions. The purpose of my faith is to become aware and share in the life of the infinite and unlimited creator God. My belief provides strength and wisdom to live all of life but does not provide the perfect philosophical apologetic. My faith leaves me with much unsolved mystery and perplexing puzzle, often my faith is accompanied by doubt and existential pain and anxiety. Evil is not a theoretical problem but an existential problem. In the face of evil we are challenged to examine who we are and what we value as well as seeking a deeper insight into the nature and purposes of God. (shrink)

Rationalists often argue that empiricism is incoherent and conclude, on that basis, that some knowledge is a priori. I contend that such arguments against empiricism cannot be parlayed into an argument in support of the a priori since rationalism is open to the same arguments. I go on to offer an alternative strategy. The leading idea is that, instead of offering a priori arguments against empiricism, rationalists should marshal empirical support for their position.

An ethic is rational if it can justify itself rationally—that is to say, if there is a “why” and a “wherefore” in it amenable to reflection, and underivative. An ethic, on the other hand, is irrational if reason and reflection are irrelevant to it, or if, being relevant, they are fundamentally subordinate, and are only the lackeys of a governing consideration which is either irrational or non-rational. The intention of this lecture is to explore the possibilities of rationalism in ethics, (...) supposing that the meaning of rationalism is, broadly speaking, what has just been stated. (shrink)

How might one explain the reliability of one's a priori beliefs? What if anything is implied about the ontology of a certain realm of knowledge by the possibility of explaining one's reliability about that realm? Very little, or so it is argued here.

A review of Albert Casullo's "A Priori Justification" (Oxford University Press).

This volume is a revival and updating of the rationalism initiated by the Cartesian cogito. Even the four main divisions of the work give evidence of this: Perception, the Real World, Real Mind, and the Suprarational. The order of treatment is not identical in every respect with that of Descartes, but the four main themes are indubitably Cartesian. While the protagonist is Descartes, the antagonist to whom this volume is consciously addressed is the empiricist and the positivist. Professor Robinson seems (...) intent on convincing the contemporary positivist that science is primarily an affair of reason and secondarily one of experience. He enlists two formidable allies of Descartes to elucidate and solidify his position. One he finds in the same century as Descartes, the redoubtable Leibniz; the other he takes from the twentieth century, Bertrand Russell. The problem of perception is resolved by the joint solution of Leibniz and Russell, a solution which rejects a naive realism in favor of a metarealism. The singular attraction of this volume is the personal dedication and expertise which Professor Robinson brings to this subject. His exploration and defense of his rationalistic premise brings him to examine epistemic issues and paradoxes which have cast long shadows over the history of modern and contemporary philosophy in Western civilization. These are the issues with which the inheritors of the Cartesian cogito have been wrestling: Spinoza, Leibniz, Locke, Berkeley, Hume, and Kant. Another very attractive aspect of this volume is that whereas Professor Robinson’s thesis has its protagonist and antagonist, it does not explicitly address itself to these. They remain more in the background as the audience to whom the book is addressed. They are not called on explicitly to engage in the exposition. In this sense, the book is not presented as a professorial treatise with copious footnotes and an extensive bibliography. It is presented as a personal exposition engaging in the act of philosophizing within the letter and spirit of a rationalistic revival. In spite of this personal and personalized renewal of rationalism on the part of Professor Robinson, it should not be construed that the book is written either for the layman or by a layman. It is a methodical and technical exposition replete with the coinage of new terms befitting the spirit of a philosophy operating within the parameters of a self-enclosed and self-contained scientism. Professor Robinson presents his book as a viable alternative to the monopoly which the empiricist and positivist have exercised within the domain of the philosophy of science.—R.E.D. (shrink)

As the title suggests, this is a volume of eighteen recent essays on Descartes, Spinoza, and Leibniz. The idea for this compilation arose out of Jonathan Bennett’s 1995 National Endowment for the Humanities Seminar on Descartes, Spinoza, and Leibniz. The authors, many of whom were involved in that seminar, worked together to create this kind of loose dialogue. While each essay stands by itself, several of the works in the volume show evidence of the influence of the other authors. As (...) the editors note, “Each author commented on at least two other chapters before the final works were submitted”, and it shows. Furthermore, the volume is consistently edited, with a coherent style, and includes provocative and scholarly essays. (shrink)

Given the particular character of Ancient Literature, I considered it useful to approach the issue from the perspective of the Philosophy of Science: Epistemologyand the Philosophy of Science stem from the same source, and this aspect is all the more patent for Antiquity. In fact, the two perspectives that I mentioned in the subtitle, Empiricism and Rationalism, both represent epistemological choices and approaches specific to the Sciences, as well as to the Philosophy of Science, in the manner that they were (...) practiced in Antiquity. This present study argues that Empiricism noticeably distinguishes itself from Rationalism, not merely in the philosophical works of the above-mentioned period, but also in its non-philosophical literature, especially the one pertaining to Science. Consequently, this study aims to indicate the major lines of thought in the Ancient Philosophy of Science, which reflect themselves in Epistemology in an unmediated manner. (shrink)

Laurence BonJour divides approaches to a priori justification into three kinds. Quine’s radical empiricism denies the existence of any special category of a priori justification; moderate empiricism attempts to explain a priori justification in terms of something like knowledge of meaning or grasp of concepts; and rationalism postulates an irreducible ‘rational insight’ into the nature of reality. The positions therefore form a familiar trio of eliminativism, reductionism and anti-reductionism concerning a priori justification. BonJour’s interesting and (in the present philosophical climate) (...) unusual project is to defend rationalism, the anti-reductionist position. Rationalism says that we have an ability to ‘directly or intuitively see or grasp or apprehend … a necessary fact about the nature or structure of reality’ (pp. 15-16). ‘An apparent rational insight,’ he says, ‘purports to be nothing less than a direct insight into the necessary character of reality’ (p. 107). Two clarifications will help to mark out the distinctive character of this view: first, that rational insight is fallible; and second, that although BonJour carefully distinguishes the concepts of necessity and apriority, he none the less claims that rational insight yields a priori knowledge of necessary truths only. On his view, the contingent a priori does not exist, although empirical necessities do... (shrink)

In this chapter, I argue against empiricist positions which claim that empirical evidence can be sufficient to defeasibly justify aesthetic judgements, or judgements about the adequacy of aesthetic judgements, or sceptical judgements about someone's capacity to form adequate aesthetic judgements. First, empirical evidence provides neither inferential, nor non-inferential justification for aesthetic opinions. Second, while empirical evidence may tell us how we do respond aesthetically to artworks, it cannot tell us how we should respond to them. And, third, empirical insights into (...) the irrationality of many of our aesthetic judgements do not warrant the sceptical conclusion that we ought to refrain from forming aesthetic opinions. As a consequence of these limitations to aesthetic empiricism, we should endorse the rationalist position that aesthetic criticism is largely a matter of reasoning and, moreover, a collective undertaking.

Hauptli presents a putative dilemma for Bartley’s pancritical rationalism that has remained unchallenged. This note sets the record straight by exposing two lacunae in Hauptli’s argument.

In this article I investigate a neglected form of radical skepticism that questions whether any of our logical, mathematical and other seemingly self-evident beliefs count as knowledge. ‘A priori skepticism,’ as I will call it, challenges our ability to know any of the following sorts of propositions: (1.1) The sum of two and three is five. (1.2) Whatever is square is rectangular. (1.3) Whatever is red is colored. (1.4) No surface can be uniformly red and uniformly blue at the same (...) time. (1.5) If ‘if p then q’ is true and ‘p’ is true, then ‘q’ is true. (1.6) No statement can be both true and false at the same time and in the same respect. (1.7) If A is taller than B, and B is taller than C, then A is taller than C. (1.8) Everything is identical to itself. (1.9) If the conclusion of an inductive argument is contingent, it is possible for the premises of that argument to be true and its conclusion to be false. (1.10) George W. Bush could have been a plumber. (1.11) George W. Bush could not have been a prime number. (1.12) ‘2 + 3 = 5’ is necessarily true. (shrink)

One of Laurence BonJour’s main arguments for the existence of the a priori is an argument that a priori justification is indispensable for making inferences from experience to conclusions that go beyond experience. This argument has recently come under heavy fire from Albert Casullo, who has dubbed BonJour’s argument, “The Generality Argument.” In this paper I (i) defend the Generality Argument against Casullo’s criticisms, and (ii) develop a new, more plausible, version of the Generality Argument in response to some other (...) objections of my own. Two of these objections stem out of BonJour’s failing to fully consider the importance of the distinction between being justified in believing that an inference is good and being justified in making an inference. The final version of the argument that I develop sees the Generality Argument as one part of a cumulative case argument for the existence of a priori justification, rather than as a stand-alone knock-down argument. (shrink)

I reconstruct and critique two arguments Laurence BonJour has recently offered against skepticism about the a priori. While the arguments may provide anti-skeptical, internalist foundationalists with reason to accept the a priori, I show that neither argument provides sufficient reason for believing the more general conclusion that there is no rational alternative to accepting the a priori.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified (or absolutely warranted), i.e., justified to a degree that entails their truth and precludes their falsity. Though rationalist infallibilism is indisputably running its course, adherence to at least one of the two species of infallible a priori justification refuses to disappear from mainstream epistemology. Among others, Putnam (1978) still professes the a priori infallibility of some category (i) propositions, while Burge (...) (1986, 1988, 1996) and Lewis (1996) have recently affirmed the a priori infallibility of some category (ii) propositions. In this paper, I take aim at rationalist infallibilism by calling into question the a priori infallibility of both analytic and synthetic propositions. The upshot will be twofold: first, rationalist infallibilism unsurprisingly emerges as a defective epistemological doctrine, and second, more importantly, the case for the a priori infallibility of one or both categories of propositions turns out to lack cogency.

What can reason do for us and what can't it do? This is the question examined by Herbert A. Simon, who received the 1978 Nobel Prize in Economic Sciences "for his pioneering work on decision-making processes in economic organizations." The ability to apply reason to the choice of actions is supposed to be one of the defining characteristics of our species. In the first two chapters, the author explores the nature and limits of human reason, comparing and evaluating the major (...) theoretical frameworks that have been erected to explain reasoning processes. He also discusses the interaction of thinking and emotion in the choice of our actions. In the third and final chapter, the author applies the theory of bounded rationality to social institutions and human behavior, and points out the problems created by limited attention span human inability to deal with more than one difficult problem at a time. He concludes that we must recognize the limitations on our capabilities for rational choice and pursue goals that, in their tentativeness and flexibility, are compatible with those limits. (shrink)

The three great historical philosophers most often associated with rationalism - Descartes, Spinoza and Leibniz - opened up ingenious and breathtaking vistas upon the world. Yet their works are so difficult that readers often find themselves stymied. "Understanding Rationalism" offers a guide for anyone approaching these thinkers for the first time.With clear explanations, elegant examples and insightful summaries, "Understanding Rationalism" unlocks their intricate metaphysical systems, which are by turns surprising, compelling and sometimes bizarre. It also lays out their controversial stances (...) on moral, political and religious problems. The study is framed by an opening discussion of the broad themes and attitudes common to these three philosophers and a closing analysis of the legacy they left for the rest of philosophy. (shrink)

In this book Gary Gutting offers a powerful account of the nature of human reason in modern times. The fundamental question addressed by the book is what authority human reason can still claim once it is acknowledged that our fundamental metaphysical and religious pictures of the world no longer command allegiance. If ethics and science remain sources of authority what is the basis of that authority? Gutting develops answers to these questions through critical analysis of the work of three dominant (...) philosophical voices in our time: Richard Rorty, Alasdair MacIntyre, and Charles Taylor. His own position is defined as 'pragmatic liberalism'. (shrink)

Experimental philosophy is one of the most exciting and controversial philosophical movements today. This book explores how it is reshaping thought about philosophical method. Experimental philosophy imports experimental methods and findings from psychology into philosophy. These fresh resources can be used to develop and defend both armchair methods and naturalist approaches, on an empirical basis. This outstanding collection brings together leading proponents of this new meta-philosophical naturalism, from within and beyond experimental philosophy. They explore how the empirical study of philosophically (...) relevant intuition and cognition transforms traditional philosophical approaches and facilitates fresh ones. Part One examines important uses of traditional "armchair" methods which are not threatened by experimental work and develops empirically informed accounts of such methods that can potentially stand up to experimental scrutiny. Part Two analyses different uses and rationales of experimental methods in several areas of philosophy and addresses the key methodological challenges to experimental philosophy: Do its experiments target the intuitions that matter in philosophy? And how can they support conclusions about the rights and wrongs of philosophical views? Essential reading for students of experimental philosophy and metaphilosophy, _Experimental Philosophy, Rationalism, and Naturalism_ will also interest students and researchers in related areas such as epistemology and the philosophies of language, perception, mind and action, science and psychology.

Aproximaciones a la escuela francesa de epistemología Los problemas que dominan a la epistemología pueden contextualizarse históricamente como una forma de racionalidad filosófica. La filosofía se ha presentado a lo largo de la historia como un discurso en el que sus diversos componentes (metafísica, ontología, gnoseología, ética, lógica, etc.) se mostraron unidos en el molde de la ?unidad del saber?. En este marco unitario alguna de las formas del saber filosófico detenta usualmente una posición dominante. El énfasis colocado en la (...) unidad del saber filosófico, o en ?la unidad del pensamiento humano?, es una herencia que el pensamiento filosófico recibe de sus raíces mítico-teológicas. Dicha visión se vio sometida, en la historia de la filosofía, a un proceso de secularización por el cual la instancia dominante pasó de la teología a la metafísica y de ésta a la teoría del conocimiento. Entre los siglos XIX y XX, este proceso atestiguó un cambio ulterior, colocando a la epistemología como instancia dominante de la racionalidad filosófica. La sucesión debe verse como una consecuencia de la funcionalización social de los dispositivos de creencias (ideología), lo que provoca que los mismos se conviertan, en determinado momento, en un obstáculo para la producción de nuevos conocimientos. De esta manera, los nuevos conocimientos, para desarrollarse, se ven forzados a provocar reestructuraciones en el campo filosófico, ya sea mediante el reemplazo de la instancia dominante, la incorporación o creación de nuevas formas de saber filosófico -tal el caso de la epistemología-, o de la marginalización relativa de otras. Se trata de en un proceso complejo (que no es ni lineal, ni biunívoco), en el que cabe no obstante discernir un esquema de la sucesión temporal de las formas filosóficas que dominan la pretendida ?unidad del pensamiento humano? (filosofía). El que acabamos de describir es un proceso lento de sustitución y reemplazo en el tipo de garantías que se le exige elaborar a la filosofía. Algunos momentos, como el ocaso de las garantías de la fe, acaecido con el surgimiento de la filosofía moderna, podrían parecer a primera vista contrajemplos para esta concepción de la evolución del saber filosófico. Podría creerse, en efecto, que con la constitución de esferas autónomas de discurso (teología, ciencia, filosofía), del discurso filosófico se desgajó en un discurso de una naturaleza diferente: la ciencia. Sin embargo, una mirada más atenta revela un paisaje diferente, puesto que esta transformación estuvo acompañada, primero, por la aparición de una nueva instancia dominante de la unificación del conocimiento filosófico. Se trata de la búsqueda de una nueva clase de garantías, las del origen y el fundamento del conocimiento, es decir, las de la gnoseología o teoría del conocimiento, en el interior de la cual se verificó finalmente un nuevo desplazamiento, con la constitución, a fines del siglo XIX y principios del siglo XX, de la ?filosofía de la ciencia? o epistemología. Este modelo para la conceptualización del desarrollo del discurso filosófico tiene la ventaja de permitirnos pensar la relación que la epistemología guarda con la instancia de saber filosófico dominante en el seno de la cual se desarrolla: la de la gnoseología. A partir de las relaciones que la epistemología guarda con la temática de las garantías del conocimiento podemos apresar, en un esquema heurístico que será complejizado de diversos modos en este libro, la diferencia entre las tesis características de la epistemología anglosajona y de la epistemología francesa. De acuerdo con en este esquema heurístico, el rasgo más característico de la epistemología anglosajona es su sujeción, en la mayor parte de su desarrollo, a la teoría del conocimiento, lo que se revela en la persistencia de algunos aspectos de la filosofía de la representación y en la reproducción de la oposición idealista entre sujeto y objeto como dos polos cuya armonía debería establecerse, filosóficamente, en términos de la verdad. En su lugar, la epistemología francesa se propuso el estudio de los mecanismos de producción de los conocimientos. La epistemología, desde esta perspectiva, ya no fue vista primordialmente como el estudio de los fundamentos del conocimiento científico, sino como la teoría de las condiciones y las formas de la práctica científica y la historia de esta práctica, tal como aparece en las distintas ciencias concretas. Expresado de otra manera, el contraste se podría establecer mediante la observación de que mientras los anglosajones hacen filosofía de la ciencia como una extensión de la lógica, los franceses la hacen como una extensión de la historia de la ciencia, es decir, encontrando en la historia el laboratorio del epistemólogo. Ahora bien, según veremos, el campo de la epistemología francesa ha cobijado una buena cantidad de debates que tienen que ver primordialmente con dos tendencias en tensión: la que enfatiza la autonomía de lo epistemológico y aquella que destaca la determinación social del pensamiento. Los trabajos de este libro esperan problematizar este y otros ejes, explorando las perspectivas de los ?clásicos? de la escuela francesa en epistemología (Bachelard, Canguilhem, Althusser, Foucault, etc.), las relaciones entre los mismos y los diálogos que cabe establecer entre estos y otras corrientes de pensamiento.
