Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or (...) the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10‐year olds and is shown to account for about two‐thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed. (shrink)

Central to Sellars’ account of human cognition was a clear distinction, expressed in varying terminology in his different works, “between conceptual and nonconceptual representations.” Those who have come to be known as ‘left-wing Sellarsians’, such as Richard Rorty, Robert Brandom, and John McDowell, have tended to reject Sellars’ appeals to nonconceptual sensory representations. So-called ‘right-wing Sellarsians’ such as Ruth Millikan and Jay Rosenberg, on the other hand, have embraced and developed aspects of Sellars’ account, in particular the central underlying (...) idea that human perceptual cognition involves a certain naturalistic ‘mapping’ correspondence or structural ‘picturing’ isomorphism between internal mental representations and the layout and behavior of objects in the surrounding environment. Sellars, despite his defenses of nonconceptual representational content throughout his career, has with no small irony come to be cited as one of the “founding fathers of conceptualism.” While recognizing the strong conceptualist elements in Sellars’ Kantian account of perceptual cognition, I argue that a central core of Sellars’ account of nonconceptual sensory contents does not by itself fall afoul of the philosophical worries raised by the left-leaning Sellarsians, and that in fact it has significant merits in its own right.

In 1839 and 1840, Newman preached four Oxford University Sermons, which critiqued the evidential apologetics advocated by John Locke (1632-1704) and William Paley (1743-1805) and subsequently restated by Richard Whately (1787-1863). In response, Newman drew upon Whately’s earlier works on logic and rhetoric to develop an alternative account of the reasonableness of religious belief that was based on implicit reasoning from antecedent probabilities. Newman’s argument was a creative response to Whately’s contention that evidential reasoning is the only safeguard against (...) superstition and infidelity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Breakdown of C i M phy " artes an eta sacs RICHARD A. WATSON WITHIN CARTESIANISMthere arose many problems deriving from conflicts between Cartesian principles. Inadequate attempts to solve these problems were crucial reasons for the breakdown of Cartesian metaphysics in the late seventeenth and early eighteenth centuries. The major difficulties derived from the acceptance of a dualism of substances seated in a system which included epistemological (...) and causal likeness principles plus an ontological framework in which the categories of substance and modification were exhaustive. The major solutions involved either denying the likeness principles or altering the ontological framework. The first led to unintelligibility ; the second, culminating in Hume, opened the way to non-Cartesian metaphysics. The first section of this study contains a characterization of late seventeenth -century Cartesian metaphysics. The second is an exposition of Foucher 's four major criticisms of this system. In the third section, monistic solutions suggested in Descartes and by Spinoza, Foucher, Leibniz, and Locke are considered; in the fourth, the dualistic solutions of the orthodox Cartesians Rohault, R~gis, Desgabets, La Forge, Le Grand, and Arnauld; and in the fifth, the occasionalist solution of Malebranche. The sixth section is an analysis of these orthodox and occasionalist solutions, showing how each ultimately fails because of dependence upon the ontology of substance and modification. The seventh section is a consideration of Berkeley and Hume in the Cartesian context. A consideration of their systems as offering solutions to Cartesian problems illuminates in new light both the systems and the problems. In broad terms, this study moves from a consideration of problems arising from an ontology of two substances, to a consideration of problems arising from the ontological pattern of substance and modification. The Cartesians were concerned with relationships between two substances, but they saw no difficulties connected with the relationship between a substance and its modifications (or properties). Berkeley's treatment (deriving from Male- [177] 178 HISTORY OF PHILOSOPHY branche) of the relationships between mind and idea, and between mind and notion, is illuminated by a consideration of the extent to which he took these relationships for granted in the Cartesian way, and of the extent to which he saw difficulties in the relationship between substance and modification. The Berkeleian solution to Cartesian problems, like that of Malebranche before him, was not successful; Malebranche belittled, and Berkeley denied the dualism of substances, but neither philosopher could break entirely with the ontological pattern of substance and modification. The final breakdown of Cartesian metaphysics came with Hume, who, in providing the culmination of a most important trend in modern philosophy, opened the way to new metaphysics and became the father of contemporary philosophy. I A model late seventeenth-century Cartesian metaphysical system. The last grand expositor of the Cartesian philosophy was Antoine Le Grand who in 1694 published An Entire Body of Philosophy. The characterization of the late seventeenth-century Cartesian system given below follows Le Grand's exposition more closely than others, but it also incorporates elements from those of Rohault, R6gis, Desgabets, La Forge, Malebranche, and Arnauld.1 None of these philosophers professed a system of exactly the sort this characterization pictures, nor is it implied here that they do. The guide and rationale for drawing from them such a model Cartesianism is the polemical writing of Simon Foucher. Foucher's series of attacks upon Cartesianism (of which the second is his criticism of Malebranche of 1675, Critique de la Rdcherche de la veritd) give clearly the most important objections against Cartesian metaphysics.2The system outlined below, while more com1Le Grand, Antoine, An Entire Body of Philosophy According to the Principles of the Famous Renate des Cartes (London, 1694); Rohault, Jacques, Traitd de physique (Paris, 1671); R6gis, Pierre-Sylvain, Syst~me de philosophie, contenant la logique, la mdtaphysique, la physique et la morale (Lyon, 1690); Desgabets, Robert, Critique de la Critique de la Recherche de la veritd, oCt l'on decouvre le chemin qui conduit aux connoissances solides.

A reciprocity framework is presented as an analysis of morality, and to explain and justify the attribution of moral rights and duties. To say an entity has rights makes sense only if that entity can fulfill reciprocal duties, i.e., can act as a moral agent. To be a moral agent an entity must (1) be self-conscious, (2) understand general principles, (3) have free will, (4) understand the given principles, (5) be physicallycapable of acting, and (6) intend to act according to (...) or against the given principles. This framework is foundational both to empirical and supernatural positions which distinguish a human milieu, which is moral, from a nonhuman milieu, which is not. It also provides a basis for evaluating four standard arguments for the rights ofnonhuman animals and nature-the ecological, the prudential, the sentimental, and the contractual. If reciprocity is taken as being central to the general concepts of rights and duties, then few animals, and no natural objects or natural systems, have rights and duties in an intrinsic or primary sense, although they may be assigned them in an extrinsic or secondary sense as a convenience in connection with human interests. Nevertheless, there are some animals besides humans - e.g., especially chimpanzees, gorillas, dolphins, and dogs - which, in accordance with good behavioral evidence, are moral entities, and sometimes moral agents. On the grounds of reciprocity, they merit, at aminimum, intrinsic or primary rights to life and to relief from unnecessary suffering. (shrink)

A dozen papers by internationally known scholars explore questions largely unthinkable without Richard Watson's classic Downfall of Cartesianism: Descartes in Holland, Descartes and Simon Foucher, and issues raised by Descartes for philosophy of mind, philosophy of science, translation and toleration.

Combines historical research and philosophical analysis to cast light on why and how Cartesianism failed as a complete metaphysical system. Far more radical in its conclusions than his 1966 study The Downfall of Cartesianism, Watson argues that Descartes's ontology is incoherent and vacuous, his epistemology deceptive, and his theology unorthodox--indeed, that Descartes knows nothing.

Richard A. Watson - What is the History of Philosophy and Why is it Important? - Journal of the History of Philosophy 40:4 Journal of the History of Philosophy 40.4 525-528 Notes and Discussions What is the History of Philosophy and Why is it Important? The advent of the fortieth anniversary of the founding of the Journal of the History of Philosophy set me to thinking again about these old disputed questions. It seems obvious that what is unique to (...) the history of philosophy is that it is history. It is specifically history of philosophical positions, principles, and arguments with no restrictions concerning who held them where or when, or what they are. The history of philosophy as history, then, is a discipline in which the philosophical positions, principles, and arguments of philosophers are presented, analyzed, and explained in the historical contexts of their times. One way to proceed is to ask and answer questions such as the following: Given our best understanding of the intellectual milieu and vernacular of the times, what did the philosopher say? Given ditto, what did the philosopher mean to say? Did he say what he meant to say? Did he support his position adequately or inadequately? What might or could the philosopher have said in the context of his times, either to improve or alter his position, or to avoid errors? How did the philosopher's contemporaries respond? Who had the better arguments? What developed philosophically out of.. (shrink)

In this engrossing double volume, the work and thought of Nicolas Malebranche is examined through the eyes of Simon Foucher and Dortous de Mairan. Part 1 consists of Richard A. Watson’s translation of the first published critique, by Simon Foucher, of Malebranche’s main philosophical work, _Of the Search for the Truth. _In the second part, Marjorie Grene presents a meticulous translation of the long correspondence between Malebranche and Jean-Jacques Dortous de Mairan that ended shortly before Malebranche’s death. Both Watson (...) and Grene provide insightful introductions to their translations. The influence of the works of Malebranche has been extensive, as has the influence of the lesser works of his first critic, Simon Foucher. Although Foucher was a minor philosopher of the seventeenth century, he provided arguments that led to a crucial turning point in modern philosophy. Listened to with care and treated with respect by Leibniz, Foucher’s arguments were utilized by Bayle, Berkeley, and Hume toward the destruction not only of Cartesian metaphysics but of substance philosophy as well. In this translation of Foucher’s work, it is now possible for readers of Malebranche’s _Of the Search for the Truth _to evaluate the immediate response of a young philosopher about town to one of the most important philosophical works of his day. The correspondence between Jean-Jacques Dortous de Mairan, an obscure provincial, and Nicolas Malebranche has usually been viewed as a small addendum to the works of Malebranche. Marjorie Grene, however, in her translation of this correspondence, considers it not only a contribution to the Malebranchian corpus but also an example of a reaction to Spinoza. Born at Béziers in the south of France in 1678, Mairan went to Paris in 1698, where he studied mathematics with Malebranche. Their correspondence began four years later when Mairan returned to Béziers to accept a position with the local bishop. In his letters to Malebranche, Mairan reveals himself to be one of no more than a handful of known readers of Spinoza who, in the early eighteenth century, admitted fascination with Spinoza’s presentation of his thoroughly unorthodox God and his equally unorthodox nature.

A monumental work on the flow of time, from the universe's creation to "Now," by the best-selling author of Physics for Future Presidents. "Now" is a simple concept--you're reading this sentence now. Yet a real definition of "now" has eluded even the great Einstein. We know that time stretches and is affected by gravity and velocity. Yet, as eminent physicist Richard A. Muller points out, it is only today that we have all the physics at hand--relativity, entropy, entanglement, antimatter, (...) and the Big Bang--to explain the flow of time. With these building blocks in place, Muller reaches a startling conclusion: our expanding universe is continuously creating not only new space but also new time. The front edge of this new time is what we call "now," and this moment is truly unique--it is the only moment in which we can exercise our free will. Muller's thought-provoking vision is a powerful counter to established theories in science and philosophy, and his arguments will spark major debate about the most fundamental assumptions of our universe.

Ame Naess, John Rodman, George Sessions, and others, designated herein as ecosophers, propose an egalitarian anti-anthropocentric biocentrism as a basis for a new environmental ethic. I outline their “hands-off-nature” position and show it to be based on setting man apart. The ecosophic position is thus neither egalitarian nor fully biocentric. A fully egalitarian biocentric ethic would place no more restrictions on the behavior of human beings than on the behavior of any other animals. Uncontrolled human behavior might lead to the (...) destruction ofthe environment and thus to the extinction of human beings. I thus conclude that human interest in survival is the best ground on which to argue for an ecological balance which is good both for human beings and for the whole biological community. (shrink)

The reputation and influence of Emmanuel Levinas has grown powerfully. Well known in France in his lifetime, he has since his death become widely regarded as a major European moral philosopher profoundly shaped by his Jewish background. A pupil of Husserl and Heidegger, Levinas pioneered new forms of exegesis with his post-modern readings of the Talmud, and as an ethicist brought together religious and non-religious, Jewish and non-Jewish traditions of contemporary thought. Richard A. Cohen has written a book which (...) uses Levinas' work as its base but goes on to explore broader questions of interpretation in the context of text-based ethical thinking. Levinas' reorientation of philosophy is considered in critical contrast to alternative contemporary approaches such as those found in modern science, psychology, Nietzsche, Freud, Husserl, Heidegger, Sartre, Merleau-Ponty, Derrida and Ricoeur. Cohen explores a manner of philosophizing which he terms 'ethical exegesis'. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Descartes’ Meditations: Background Source Materials ed. by Roger Ariew, John Cottingham, and Tom SorellRichard A. WatsonRoger Ariew, John Cottingham, and Tom Sorell, editors. Descartes’ Meditations: Background Source Materials. Cambridge: Cambridge University Press, 1998. Pp. xviii + 170. Cloth, $54.95. Paper, $18.95.This volume includes primarily source materials from authors who were contemporary to Descartes’s composition of the Meditations. Thus there are no selections from Augustine, Aquinas, and Montaigne, for (...) example, who were more influential on the Meditations than some of the authors excerpted. Of course their influence is already amply documented by such scholars as Gilson and Gouhier. Probably the most important source included is Suárez, whose role is championed by Jean-Luc Marion in several works. Readers should look for the forthcoming Index Augustino-Cartèsian: Textes et Commentaire by Zbigniew Janowski (Paris: J. Vrin) for a startling challenge to the view that Descartes is Suárezian.In the volume under review, Eustachius a Sancto Paulo is of special interest because Descartes thought of refuting him item by item (but decided exposition of his own view would be adequate). In his youth Descartes had a definite interest in Petrus Ramus, although Beeckman told him his method consisted of tired old tricks. Francisco Sanches and Pierre Charron are important for their expositions of sceptical arguments and attitudes. Christopher Clavius is Descartes’s direct predecessor in mathematical analysis, and none of Descartes’s protests that he never read the man has convinced anyone. Scipion Dupleix is a fine example of how the Old Philosophy appeared to the New Philosophers, and Marin Mersenne, of course, compiled material on every subject Descartes ever had an interest in. Pierre Gassendi exercised Descartes’s ire more than any other commentator on the Meditations, and Descartes again probably read Gassendi’s continuing criticisms even though he claimed he wouldn’t. [End Page 366]Of special interest is Jean de Silhon, an old friend of Descartes’s who published a book containing a proto-cogito three years before the Meditations appeared. François de la Mothe le Vayer represents the libertine strain many detect in Descartes’s writings, while Jean-Baptiste Morin provides fodder for those who detect Descartes’s piety, although Descartes asserts that the man is an idiot for defending the immobility of the earth. Finally, Charles Sorel provides an example of the deductive mode of exposition in a text that shows that the notion of a unified science was more than Cartesian. One contemporary who was left out and should have been included was the Augustinian Guillaume Gibieuf.But overall, this is an interesting and useful collection of works Descartes doubtless knew.
