Rationalism, Misc

Enlightenment philosopher, René Descartes, set out to establish what could be known with certainty, untainted by a deceiving demon. With his method of doubt, he rejected all previous beliefs, allowing only those that survived rigorous scrutiny. In this essay, Leslie Allan examines whether Descartes's program of skeptical enquiry was successful in laying a firm foundation for our manifold beliefs. He subjects Descartes's conclusions to Descartes's own uncompromising methodology to determine whether Descartes escaped from a self-imposed radical skepticism.

Two common claims in philosophy are that deep disagreements cannot, in principle, be resolved by argument and that normal disagreements will be resolved by argument. In each claim it is assumed that the parties to the disagreement are rational. I argue that both claims are false. The first fails to take account of refutations. The second fails to recognise the role of conjectures in the dynamics of the growth of knowledge. There is no disagreement such that it is impossible for (...) rational parties to reach agreement by argument; but there is also no disagreement for which parties are rationally required to reach agreement by argument. Given the same evidence, it may be rational for one person to believe a specific proposition and another to believe its negation. (shrink)

We analyse Peirce's original idea concerning abduction from the perspective of a critical philosophy, the same philosophy in Peirce's background. Peirce's realism is directly related to reason and experience and has ties with the idea of abstraction. We show how the philosophical environment of science abruptly changed, specially for physics, in the last period of the XIX century and the initial period of the XX century, when science was divided in disciplines and set free from the control of philosophy. The (...) phenotype of the physicist changed from abstract into imaginative thinker. Further, abstraction was linked to metaphysics and attacked as such. Elements of phantasy and dogmatism entered the scene in place of abstraction alongside ideas taken from the observable world. We provide evidence that the scientists of the newer kind had problems understanding those of the older school. As a consequence of the problems arisen in conciliating the idea of science grounded in experience and reason with the science actually practised, the former conceptualisation was abandoned. Abduction was then expelled from science. In the late part of the XX century and the early part of our century abduction re-emerged but without its scientific attributes. -/- Influenced by a constructivist, Piagetian, perspective of science, we propose and discuss a small number of conditions that we identify as characteristics of rational abduction: rules for the rational construction of theories. We show how a classical example of belief that satisfies today's most common definition of abduction does not match the standards of scientific retroduction. We further show how the same rules indicate the detachment of Special Relativity from the observable world, a fact actually known to Einstein. Finally, the same rules indicate the initial point in the path to re-conciliate Electromagnetism with the classical view of spatial relations, a matter not possible for the imaginative scientist but not extremely difficult for the abstract scientist. We close arguing that there is an urgent need to develop a critical epistemology, and to give room in science for the abstract scientist. (shrink)

There is much to admire in John Pittard’s recent book on the epistemology of disagreement. But here we develop one concern about the role that rational insight plays in his project. Pittard develops and defends a view on which a party to peer disagreement can show substantial partiality to his own view, so long as he enjoys even moderate rational insight into the truth of his view or the cogency of his reasoning for his view. Pittard argues that this may (...) happen in ordinary cases of religious disagreement—cases in which it’s a live skeptical possibility that one is misdescribing his insight, or not having insight at all—and therefore one need not be strongly conciliatory even in the face of peer disagreement. Yet Pittard agrees that one should be strongly conciliatory in cases of disagreement involving, e.g., visual perception and dim rational insight, since the sort of fallible, corrigible evidence involved in such cases may be counterbalanced by symmetrical evidence on the part of one’s disagreeing peer. We worry that there’s an inconsistency here. If it’s unreasonable to show partiality to one’s visual experience (or dim rational insight) in cases like “Horse Race” and “Restaurant Check,” it’s likewise unreasonable to show partiality in religious disagreements to one’s moderate rational insight, fallible and corrigible as it is.

There is a divide in epistemology between those who think that, for any hypothesis and set of total evidence, there is a unique rational credence in that hypothesis, and those who think that there can be many rational credences. Schultheis offers a novel and potentially devastating objection to Permissivism, on the grounds that Permissivism permits dominated credences. I will argue that Permissivists can plausibly block Schultheis' argument. The issue turns on getting clear about whether we should be certain whether our (...) credences are rational. (shrink)

I introduce the key ideas of foundationalist, coherentist and pragmatist theories of knowledge. I then use these ideas as background for presenting the work on knowledge and perception in this part, work by Grace Andrus de Laguna and Marie Collins Swabey. We will see that these authors critique the idea of sense data that was central to the foundationalist theories of knowledge of Bertrand Russel and other early analytic thinkers, though de Laguna’s critique leads to perspectivism about perception and knowledge (...) while Swabey rejects perspectivism. So too, we will see that de Laguna and Swabey develop epistemologies with strong coherentist elements, much as did their idealist teacher James Edwin Creighton. De Laguna’s, developed jointly with her husband, Theodore de Laguna, is a sophisticated form of naturalism that is built on a critique of pragmatist naturalism and is similar to the one made famous later by Willard V. Quine. Swabey rejects all forms of naturalism, arguing that knowledge requires an a priori foundation in reason. (shrink)

Intuition-based accounts of the a priori are criticised for appealing to a “mysterious” faculty of rational intuition to explain how a priori knowledge is possible. Analyticity-based accounts are typically motivated by opposition to them, offering a purportedly “non-mysterious” account of the a priori. In this paper, I argue that analyticity-based accounts are in no better position to explain the a priori than intuition-based accounts, and that we have good reason to doubt the explanation they offer. To do this, I focus (...) on recent analyticity-based accounts of the a priori, which appeal to understanding alone to explain the a priori. First, I argue that the appeal to understanding as the source of the a priori is no less mysterious than the appeal to rational intuition. Second, I argue that analyticity-based accounts of the a priori do not provide an alternative to intuition-based accounts as the fundamental explanation they offer of the a priori is one that could equally be endorsed by a friend of rational intuition—and that they fail for reasons that do not undermine intuition-based accounts.

How poor are they that have not patience! What wound did ever heal but by degrees? Thou knowest we work by wit and not by witchcraft, And wit depends on dilatory time. —Othello II: iii. Have you abandoned your engagement with the project of enlightenment, liberty, and progress because you have grown cynical about the effectiveness of sound argument? When someone tells you you’re wasting your time arguing with them because argument is an illusion, do you have an answer? Today, (...) it’s popular to depict people as irrational puppets of charismatic leaders, drawn unwittingly along by the emotional tides of crowds, mesmerised by the visual propaganda of flag-waving parades and historical statues glistening in the light of ideological firework displays. Witness the otherwise excellent periscopes of Scott Adams. We are told that we are living in a Post-Truth society. Logic and truth are irrelevant. Facts and logic don’t persuade, and “master persuaders” such as Donald Trump avoid them. Adams writes: “A good general rule is that people are more influenced by visual persuasion, emotion, repetition, and simplicity than they are by details and facts…If you’re using super-strong persuasion, you can be wrong on the facts, and even the logic of your argument, and still win.” Scott Adams is in the same tradition of thought as Danielle Kahneman, author of Thinking, Fast and Slow [2011], and winner of the Nobel prize in bias-research. This tradition emphasises the irrational and assumes that biases expose the irrational in humans. Kahneman carefully refrains from saying that humans are robots or 90% irrational, as Adams is inclined to say, but his emphasis still lies on the irrationality of humans. This now fashionable line of thought — though full of fascinating research — can be deeply misleading and demoralising for those committed to sound argument. Fortunately, there is no cause for despondency. (shrink)

In his Consciousness and Fundamental Reality (2017) Philip Goff defends his anti-physicalist argument against what he calls the "Dual Carving" objection—the idea that two representations of the very same fact could both be conceptually independent and "transparent," that is, revealing of the essences of the entities in question. His defense invokes a thesis he calls "Minimal Rationalism." I explore exactly how Minimal Rationalism is supposed to turn aside the objection and argue that the formulation of Minimal Rationalism on offer is (...) ambiguous between stronger and weaker readings. Goff needs the stronger reading to use it in defense of his argument, but only the weaker reading is warranted by the considerations he brings to bear in favor of his rationalism. His minimal rationalism is, in sum, insufficiently minimal. The upshot is not only that Goff is deprived of a way of turning back an important objection to his case against physicalism; we also gain a better sense of what kind of rationalist thesis is properly invoked in metaphysics.

While the Enlightenment promoted thinking for oneself independent of religious authority, the ‘Endarkenment’ (Millgram 2015) concerns deference to a new authority: the specialist, a hyperspecializer. Non-specialists need to defer to such authorities as they are unable to understand their reasoning. Millgram describes how humans are capable of being serial hyperspecializers, able to move from one specialism to another. We support the basic thrust of Millgram’s position, and seek to articulate how the core idea is deployed in very different ways in (...) relation to extremely different philosophical areas. We attend to the issue of the degree of isolation of different specialists and we urge greater emphasis on parallel hyperspecialization, which describes how different specialisms can be embodied in one person at one time.

A critical review of Wittgenstein's 'On Certainty' which he wrote in 1950-51 and was first published in 1969. Most of the review is spent presenting a modern framework for philosophy (the descriptive psychology of higher order thought) and positioning the work of Wittgenstein and John Searle in this framework and relative to the work of others. It is suggested that this book can be regarded as the foundation stone of psychology and philosophy as it was the first to describe the (...) two systems of thought and shows how our unshakable grasp of the world derives from our innate axiomatic System 1, and how this interacts with System 2. It was a revolution in epistemology since it showed that our actions rest not on judgements but on innate undoubtable axioms leading directly to action. I situate the work of Wittgenstein and Searle in the framework of the two systems of thought prominent in thinking and decision research, employing a new table of intentionality and new dual systems nomenclature. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019). Those interested in more of my writings may see ‘Talking Monkeys--Philosophy, Psychology, Science, Religion and Politics on a Doomed Planet--Articles and Reviews 2006-2019 3rd ed (2019), The Logical Structure of Human Behavior (2019), and Suicidal Utopian Delusions in the 21st Century 4th ed (2019) .

Laurence BonJour and more recently James Beebe have argued that the best way to defend the claim that abduction or inference to the best explanation is epistemically justified is the rationalist view that it is justified a priori. However, rationalism about abduction faces a number of challenges. This chapter focuses on one particular, highly influential objection, that there is no interpretation of probability available which is compatible with rationalism about abduction. The rationalist who wants to maintain a strong connection between (...) epistemic justification and probability would do best to rely on a Keynesian interpretation of probability. However, the latter is vulnerable to Ramsey’s famous criticism that we do not seem to perceive or be aware of such probabilities. The chapter argues that Ramsey’s criticism is unsuccessful, and that there are good reasons to be optimistic about our ability to have access to probabilities relevant to abductive inference.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

Mit der Entfaltung des Problems der „zwei Reihen“, der Genesis philosophischer Begriffsbildung, vollzog Fichte einen paradigmatischen Einschnitt im Hinblick auf die Fassung der Rolle begrifflicher Momente in der menschlichen Erkenntnis. Dieser Schnitt erscheint aus der Perspektive des durch Hegel entfalteten Prinzips des Aufsteigens vom Abstrakten zum Konkreten gleichsam als ‚erledigt’. Eine solche Perspektive verdeckt jedoch den vollzogenen qualitativen Umbruch. Dieser gewinnt dadurch Kontur, wenn die durch Fichte angesprochenen Positionen in Beziehung zu der vorangegangenen Ausbildung methodischer Positionen in der europäischen Aufklärung (...) gesetzt werden. -/- With the development of the problem of the "two rows", the genesis of philosophical concept formation, Fichte made a paradigmatic break with regard to the understanding of the role of conceptual moments in human knowledge. From the perspective of the principle developed by Hegel of ascending from the abstract to the concrete, this cut appears as 'done', so to speak. Such a perspective, however, conceals the qualitative upheaval that has taken place. This gains contours when the positions addressed by Fichte are related to the previous formation of methodical positions in the European Enlightenment. (shrink)

This article is a critique of Gal Yehezkel’s attempt to refute subjectivism about normative practical reasons, a school of thought inspired by Hume. Yehezkel believes reason, far from being, as Hume puts it, “the slave of the passions,” has the normative authority to be a critic of basic desires and argues that subjectivism lacks the theoretical resources both to acknowledge this alleged truth and to analyze the distinction between wanting an outcome and intending to pursue it. I contend his refutation (...) fails, largely because it operates with a strikingly attenuated view of the subjectivist theory. (shrink)

Abdolkarim Soroush’s thought is regarded by some researchers as a turning point in contemporary Islamic reform discourse. This article concerns Soroush’s epistemology as a determining factor in this paradigm shift and interprets this shift as an epistemological turn in Islamic reform discourse, shifting from ›Islamic genealogy of modernity‹ to rationalization of Islamic methodology. After a short introduction to Soroush’s intellectual biography, this article will isolate neorationalism or neo-Mu’tazilism, religious post-positivism, historicism, hermeneutics, and dialogism as main features of Soroush’s epistemology. This (...) paper suggests that rationalism as reasoning independent from revelation and non-essentialism are two main determining pillars of Soroush’s epistemology. In the conclusion, I shortly compare Soroush’s thought with some other contemporary Muslim reform thinkers and discuss how and why Soroush’s thought can be interpreted as an epistemological turn in Islamic reform discourse.

Millians about proper names typically claim that it is knowable apriori that Hesperus is Phosphorus. We argue that they should claim instead that it is knowable only aposteriori that Hesperus is Hesperus, since the Kripke-Putnam epistemic arguments against descriptivism are special cases of Quinean arguments that nothing is knowable apriori, and Millians have no resources to resist the more general Quinean arguments.

Rationalism, my target, says that in order to have perceptual knowledge, such as that your hand is making a fist, you must “antecedently” (or “independently”) know that skeptical scenarios don’t obtain, such as the skeptical scenario that you are in the Matrix. I motivate the specific form of Rationalism shared by, among others, White (Philos Stud 131:525–557, 2006) and Wright (Proc Aristot Soc Suppl Vol 78:167–212, 2004), which credits us with warrant to believe (or “accept”, in Wright’s terms) that our (...) senses are reliably veridical, where that warrant is one we enjoy by default, that is, without relying on any evidence or engaging in any positive argument. The problem with this form of Rationalism is that, even if you have default knowledge that your senses are reliable, this is not adequate to rule out every kind of skeptical scenario. The problem is created by one-off skeptical scenarios, scenarios that involve a highly reliable perceiver who, by a pure fluke, has a one-off, non-veridical experience. I claim you cannot infer that your present perceptual experience is veridical just on the basis of knowledge of your general reliability. More generally, if you infer that the present F is G, just on the basis of your knowledge that most Fs are Gs, this is what I call statistical inference, and, as I argue, statistical inference by itself does not generate knowledge. I defend this view of statistical inference against objections, including the objection that radical skepticism about our ordinary inductive knowledge will follow unless statistical inference generates knowledge.

Debunking arguments are arguments that aim to undermine some range of beliefs by showing that those beliefs are not appropriately connected to their subject matter. Arguments of this sort rear their heads in a wide variety of domains, threatening beliefs about morality, mathematics, logic, color, and the existence of God. Perceptual beliefs about ordinary objects, however, are widely thought to be invulnerable to such arguments. I will show that this is a mistake. I articulate a debunking argument that purports to (...) undermine our most basic perceptual beliefs. I then challenge a number of responses to the argument, including the “permissivist” response that there are a plenitude of objects before us, virtually guaranteeing the accuracy of our object beliefs.

The crisis of our times is that we have science without wisdom. Modern science and technology lead to modern industry and agriculture which in turn lead to all the great benefits of the modern world and to the global crises we face, from population growth to climate change. The fault lies, not with science, but with science dissociated from a more fundamental concern with problems of living. We urgently need to bring about a revolution in academia so that the fundamental (...) task becomes to help humanity learn how to tackle problems of living in increasingly cooperatively rational ways, so that we may gradually discover how to make progress towards a better, wiser world.

Moderate rationalism is the view a person's having a rational intuition that p prima facie justifies them in believing that p. It has recently been argued that moderate rationalism requires empirical support and, furthermore, that suitable empirical support would suffice to convince empiricists to abandon their opposition to rationalism. According to one argument, the causal requirement argument, empirical evidence is necessary in order to justify the claim that any actual token belief is based on rational intuition and moderate rationalism requires (...) such a claim for its justification. According to a second argument, the reliability argument, empirical evidence is necessary in order to justify the claim that a putative source of evidence is reliable and moderate rationalism requires such a claim for its justification. According to a third argument, the empirical case argument, certain sorts of empirical evidence would be dialectically sufficient to resolve the traditional dispute between empiricists and rationalists in the rationalists' favor. Against the causal requirement argument, I maintain that the core doctrines of moderate rationalism are not hostage to causal claims and that such causal claims as may be plausibly part of other recognizably rationalist doctrines can be justified on broadly non-empirical grounds. Against the reliability argument, I show that no empirical evidence is required to justify belief in the reliability of rational intuition. Against the empirical case argument, I argue that the envisioned empirical support for moderate rationalism should not convince any traditional empiricist. (shrink)

In this essay we argue that reasoning can sometimes generate epistemic justification, rather than merely transmitting justification that the subject already possesses to new beliefs. We also suggest a way to account for it in terms of the relationship between epistemic normative requirements, justification and cognitive capacities.

In this paper I assume that we have some intuitive knowledge—i.e. beliefs that amount to knowledge because they are based on intuitions. The question I take up is this: given that some intuition makes a belief based on it amount to knowledge, in virtue of what does it do so? We can ask a similar question about perception. That is: given that some perception makes a belief based on it amount to knowledge, in virtue of what does it do so? (...) A natural idea about perception is that a perception makes a belief amount to knowledge in part by making you sensorily aware of the concrete objects it is about. The analogous idea about intuition is that an intuition makes a belief amount to knowledge in part by making you intellectually aware of the abstract objects it is about. I expand both ideas into fuller accounts of perceptual and intuitive knowledge, explain the main challenge to this sort of account of intuitive knowledge (i.e. the challenge of making sense of intellectual awareness), and develop a response to it.

The traditional problems of epistemology have often been thought to be properly solved only by the provision of an argument, with premises justified by rational intuition and introspection, for the probable truth of our beliefs in the problematic domains. Following the lead of Thomas Reid, a sizable number of contemporary epistemologists, including many proponents of so-called "Reformed epistemology" regarding religious belief, reject as arbitrary the preferential treatment of reason and introspection implicit in the traditional view of the problems. These "Reidians" (...) insist that the traditional problems cannot be solved in the expected manner, but they go on to suggest that this result is of little significance because similar skeptical questions can be raised regarding a priori and introspective justification. After making clear the significance of the Reidian objection, I endeavor to defend the traditional preference for rational intuition over our other sources of belief by demonstrating that the usual skeptical worries cannot be equally raised against a priori justification. Then, after a brief consideration of some unduly neglected passages in Reid's writings in which he appears to concede that the traditional partiality to reason and introspection is not, in fact, arbitrary, I argue that it is the Reidians who are guilty of arbitrary partiality.

After briefly expositing some fundamental issues in current debates about apriority, I go on to critically examine meaning-based explanations of how we acquire apriori justification.

En Razón, Verdad e Historia Hilary Putnam caracterizó la racionalidad informal como una alternativa que permite superar las limitaciones evidenciadas por las concepciones formalistas de la racionalidad. Se revisa inicialmente la caracterización ofrecida por Putnam y se establece que si bien Putnam niega todo principio universal de racionalidad, admite principios relativos, generales e indeterminados, que permanecen sujetos a necesidades de interrelación cognitiva con el entorno. A continuación, se muestra que los principios aceptan excepciones, y, a partir de aquí se defiende (...) y analiza la posibilidad de revisión de principios cuya negación no resulta actualmente concebible. Finalmente, se afirma que tanto exponer como preservar creencias de la controversia constituyen elementos históricos que deben ser contemplados por una concepción informal de la racionalidad. In Reason, Truth and History, Hilary Putnam characterized informal rationality as an alternative that allows to overcome limitations evidenced by the formalist conceptions of rationality. Initially, the paper reviews the characterization provided by Putnam and establishes that, while Putnam denies any universal principle of rationality, he accepts relative, general and vague principles, that remain subject to needs of cognitive interrelationship with the environment. Secondly, we show that principles make exceptions and defend the possibility of reviewing principles whose denial is currently not conceivable. Finally, we state that both expressing and maintaining beliefs of controversy are historical elements that should be contemplated by an informal conception of rationality. (shrink)

Originally published in 1991, The Laboratory of the Mind: Thought Experiments in the Natural Sciences, is the first monograph to identify and address some of the many interesting questions that pertain to thought experiments. While the putative aim of the book is to explore the nature of thought experimental evidence, it has another important purpose which concerns the crucial role thought experiments play in Brown’s Platonic master argument.In that argument, Brown argues against naturalism and empiricism (Brown 2012), for mathematical Platonism (...) (Brown 2008), and from the Platonist-friendly, abstract universals posited by the Dretske-Tooley-Armstrong (DTA) account of the laws of nature to a more general, physical Platonism. The Laboratory of the Mind is where he takes this final step. (shrink)

In recent years many influential philosophers have advocated that philosophy is an a priori science. Yet very few epistemology textbooks discuss a priori knowledge at any length, focusing instead on empirical knowledge and empirical justification. As a priori knowledge has moved centre stage, the literature remains either too technical or too out of date to make up a reasonable component of an undergraduate course. Edwin Mares book aims to rectify this. This book seeks to make accessible to students the standard (...) topics and current debates within a priori knowledge, including necessity and certainty, rationalism, empiricism and analyticity, Quine's attack on the a priori, Kantianism, Aristotelianism, mathematical knowledge, moral knowledge, logical knowledge and philosophical knowledge.

In these comments I briefly discuss three aspects of the empiricist account of the epistemic role of experience that Anil Gupta develops in his Empiricism and Experience. First, I discuss the motivations Gupta offers for the claim that the given in experience should be regarded as reliable. Second, I discuss two different ways of conceiving of the epistemic significance of the phenomenology of experience. And third, I discuss whether Gupta's account is able to deliver the anti-skeptical results he intends it (...) to. I close by suggesting that, once fully fleshed out, Gupta's account is best understood in terms of the fusion of certain core ideas within both the empiricist and the rationalist traditions.

The philosophers René Descartes (1596–1650), Nicolas Malebranche (1638–1715), Benedict Spinoza (1632–77), and Gottfried Wilhelm Leibniz (1646–1716) are grouped together as rationalists because they held that human beings possess a faculty of reason that produces knowledge independently of the senses. In this regard, they contrast with empiricist philosophers, such as John Locke and David Hume, who believed that all knowledge arises from the senses. The rationalists contended that proper use of reason would yield the first principles of metaphysics, the most basic (...) science of all. Metaphysics was also called “first philosophy,” and it took as its subject matter nothing less than the basic properties and principles of everything. For our purposes, it is important to note that the rationalists believed that metaphysics could provide foundations for specialized disciplines, including ethics and physics, and also medicine and other applied subjects. The rationalists and their followers developed theoretical positions of ambitious intellectual scope, ranging from metaphysical conclusions about the existence and nature of God to detailed theories of physical and physiological processes. Although they put great store in the faculty of reason for establishing overarching principles, they looked to observation and experience to provide data and evidence for their detailed theories. They took special interest in the metaphysics and physics of the human organism, and this led them to psychological topics concerning the characteristics and principles of animal behavior, the process of sense perception, the passions, and emotions, and appetites, the cognitive operations of the mind (including attention and understanding), and the relation between mental phenomena and bodily processes in the brain and sense organs. The various rationalists, but especially Descartes, made original contributions to these topics. After considering the character of psychology as a discipline in the seventeenth century, we will examine these contributions in turn. (shrink)

On 18th century Kant found the Swedenborg's writings, and then wrote an aggressive refutation titled "The dream of a visionary". But Kant did not understand the Swedenborg experience and theories really. Because his rationalism he was unable to do that. This paper analyse the Kant's argumentation and shows its weak points and his inadequacy.

The traditional way of drawing the a priori/a posteriori distinction, bequeathed to us by Kant, leads to overestimating the role that experience plays in justifying ourbeliefs. There is an irony in this: though Kant was in the rationalist camp, his way of drawing the distinction gives an unfair advantage to radical empiricism. I offer an alternative way of drawing the distinction, one that does not bias the rationalist/empiricist debate.

This paper criticizes the epistemological doctrine of moderate rationalism that has been defended in recent years by such writers as Laurence BonJour, Alvin Plantinga, and George Bealer. It is argued that this new form of rationalism is really no better than the old one and that the key claim common to both---that intuition or rational insight provides a satisfactory basis for a priori knowledge---is untenable. Most of the criticism is directed specifically against Laurence BonJour’s recent “dialectical” defense of the doctrine. (...) Since BonJour’s defense is essentially an attempt to show how a priori knowledge is possible, an alternative, empiricist view of a priori knowledge is presented that eludes his objections and is supported by the criticism brought against moderate rationalism.

BonJour’s intricately argued and provocative book raises a fundamental challenge for the empiricist: if we lack the capacity for direct apprehension of necessary truths, how do we know so much? How do we know about logic and mathematics and other apparently a priori subjects? How do we know about generalities, about the past and the future, about objects that are not present? How do we know about the relations that hold between premises and conclusions? If the first half of BonJour’s (...) book is right, the empiricist is unable to answer these questions, for she is unable to explain how our beliefs in such things are justified. Lacking such an explanation, the empiricist would be committed to an extreme and unacceptable form of skepticism—call this the indispensability argument. The rationalist, by contrast, has an answer to these questions, and if the second half of BonJour’s book is right, the answer is both epistemologically and metaphysically unobjectionable— call this the possibility argument.

In recent years empiricism has come under attack. Some argue that the view is incoherent and conclude, on that basis, that some knowledge is a priori. Whatever the merits of such arguments against empiricism, they cannot be parlayed into an argument in support of the a priori unless the latter is not open to those arguments. My primary contention is that the a priori is open to the arguments offered against empiricism. Hence, they do not advance the case for the (...) a priori. I go on to offer an alternative strategy. The leading idea is that, instead of arguing against empiricism, rationalists should marshal empirical support for their position. (shrink)

This collection presents some of the most vital and original recent writings on Descartes, Spinoza, and Leibniz, the three greatest rationalists of the early modern period. Their work offered brilliant and distinct integrations of science, morals, metaphysics, and religion, which today remain at the center of philosophical discussion.

The contributors include some of the most prominent writers (...) in the field, including Jonathan Bennett, Michael Della Rocca, Jan A. Cover, Catherine Wilson, Stephen Voss, Edwin Curley, Don Garrett, and Margaret D. Wilson. (shrink)

A comprehensive defence of the rationalist view that insight independent of experience is a genuine basis for knowledge.

Scholars from various philosophical schools of thought, including cultural relativism, hermeneutics, and postmodernism, have recently critiqued rationalism in light of new developments in the cognitive sciences. Each of these new developments set into motion new inquiries in each school philosophical school of thought. Now, in Facets of Rationality, a distinguished team of scholars examines these new inquiries and bring rationality back into the mainstream of the social sciences. The unique feature of this book lies in its multidisciplinary exploration of rational (...) concerns and in discovering the integral meaning of rationality as viewed by the perspectives of different disciplines. As such, it will of considerable interest to those involved with the study and teaching of philosophy, theoretical psychology, cognitive science, political theory, and linguistics. (shrink)
