In general the debunker has more fun, especially when the weight of tradition favors the ennobling, if not the beatification, of its subject.Descartes is a case in point. Until a few years ago, there was in English no satisfactory biography. Now there are three: an "intellectual biography" by Stephen Gaukroger, the Descartes of Geneviève Rodis-Lewis, and Watson's. Gaukroger dwells on Descartes's natural philosophy, especially in the early years. Only after 300 pages does he reach the period of the Discourse, Descartes's first published work. Rodis-Lewis offers a more even-handed treatment, the fruits of a lifetime of study. Her Descartes resembles, not the modern scientist or professional philosopher, but the ancient sage for whom metaphysics is a once-in-a-lifetime affair, and even natural philosophy subordinate to wisdom. Watson's Descartes is an altogether more worldly type, born into a family of lawyers, well-connected, touchy [End Page 113] about his place in social and scientific circles, and not all that interested in what we think of now as philosophy. Nor, for that matter, is Watson: you will look in vain for an analysis of the Meditations, a discussion of method, or a definition of générosité. (Watson does conclude, I should note, with a discussion of Descartes's doctrine on the soul, whose title might well have been "The future of an illusion" if Freud had not used it already.)If you like your philosophy uncluttered by context, if you find it worthwhile to read or write about "Cartesian skepticism" or "Cartesian dualism" without troubling yourself to understand who the historical Descartes was, or what might have moved him to confront the skeptics and save the soul, then Watson is not for you. It is emphatically a Life, not a Life and Works. It is, moreover, a life in the manner of many modern biographers, in which the biographer, rather than conceal himself behind the curtains of scholarly convention, figures into the narrative, retracing the steps of Descartes's passage to Italy, examining the baptismal certificate of Descartes's illegitimate daughter Francine, and eating lunch at the Queen Kristina restaurant "next door to the house in which Descartes died" (303). The quality of a biography thus written depends in part on the personality of its author (and in the case of Cogito Ergo Sum, the author's wife, who intervenes more than once on the side of common sense during their peregrinations). Watson is, to my mind, an agreeable companion, dedicated to the search for biographical truth, impatient with hagiographic fog and time-hallowed error, down-to-earth in his assessment of Descartes's motives and circumstances.One example to show the differences among the three biographies. In November 1618 Descartes met the future Latin schoolmaster Isaac Beeckman in Breda. Beeckman records with enthusiasm their joint endeavors in physico-mathematics over the next few months (Gaukroger has the details). It seems clear that the impetus for studying the various problems mentioned in Beeckman's Journal came from Beeckman, who had been pondering physical questions since 1613 or before. Descartes's contribution, at least at first, was his immense mathematical skill. Their interests lay largely within the "mixed mathematics" of the period, especially hydrostatics and mechanics. They also discussed music, an aspect of the "new science" now often neglected (but see H. F. Cohen, Quantifying Music [Dordrecht, 1984]). On New Year's day 1619 Descartes presented Beeckman with his Compendium musicæ (Gaukroger 74, Rodis-Lewis 51/29). A decade later, Descartes, having heard that Beeckman had appropriated the Compendium to himself, became angry and eventually, late in 1630, dismissed Beeckman with a masterpiece of de haut...

Analytical philosophy opens new perspectives of studies in the history of philosophy. There are generalized history of analytical interpretations of Cartesian principle cogito ergo sum and analysis of Cartesianism through the prism of contemporary philosophy of action, with special attention to performativity of the mentioned principle. The importance of such research necessarily goes beyond "pure" history of philosophy: it also contributes to revision of traditional approaches to justification of knowledge, which still remain problematic. Attention to performativism of (...) class='Hi'>cogito ergo sum thesis is the key to new convenient interpretation of knowledge justification problem, because it allows for justification as selfjustification in terms of accomplishment. Inevitable accomplishment, peculiar to evidfently performative knowledge, suggests that fundamentalist strategy of knowledge justification, in the perspective of philosophy of action, amounts to a preferable interpretation compared to traditional epistemological approach.

Le « cogito, ergo sum » cartésien apparaît depuis quarante ans comme « inférence et performance » (J. Hintikka). Mais de quelle inférence s'agit-il précisément ? Pour le savoir, cet article poursuit deux objectifs : d'abord, montrer que la question pertinente à laquelle il s'agit de répondre ne concerne pas la relation logique interne qui lie le cogito au sum, et qui est une intuition, mais celle, externe, qui lie le « cogito, ergo sum » (...) tout entier au « quicquid cogitat, est ». Ensuite, montrer que cette dernière relation est tout à la fois une induction et une déduction. (shrink)

ABSTRACT E. M. Curley has said that Descartes’ cogito, ergo sum “is as obscure on examination as it is compelling at first glance.” Why should that be? Maybe because the cogito raises so many textual and interpretive questions. Is it an argument or an intuition? If it is an argument, does it require an additional premise? Is it best interpreted as a “performance?” Is it best seen as the discovery that any reason proposed for doubting its success (...) entails the meditator’s existence? And so on. But all these questions typically arise in the wake of worries about the cogency of the cogito when it is treated as an argument and worded in its canonical form, “I think, therefore I exist.” In this essay, I focus on what I take to be the most fundamental reason for questioning the cogito’s cogency when it is so treated—namely that the “I” in its premise is question-begging. I distinguish that reason from other reasons that are sometimes conflated with it, and I argue that it is not a good reason. I then comment on some of the questions mentioned above in light of my defense of the cogito seen in that traditional way. (shrink)

Our use of ‘I’, or something like it, is implicated in our self-regarding emotions, in the concern to survive, and so seems basic to ordinary human life. But why does that pattern of use require a referring term? Don't Lichtenberg's formulations show how we could have our ordinary pattern of use here without the first person? I argue that what explains our compulsion to regard the first person as a referring term is our ordinary causal thinking, which requires us to (...) find a persisting object as the mechanism that underpins the causal structure we naturally ascribe to the self. I thus argue against Peacocke's picture (2012), on which it's the cogito that explains one's knowledge of one's own existence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 26.2 (2002) 465-468 [Access article in PDF] Cogito Ergo Sum: The Life of René Descartes, by Richard Watson; vii & 375 pp. Boston: David R. Godine, 2002, $35.00. Scholarly in what it delivers, but delightful in how it delivers what it delivers, Cogito Ergo Sum is highly informative and fun to read. Touching on all the key places, players and events in (...) the philosopher's life, Watson tells us (at least) everything we wanted to know about Descartes as he cuts through the myths that have been passed down to us about him. Cutting through the myths meant dissociating his biography ("the first biography of Descartes since 1920 that is based on substantial new research, and the only one ever written for general readers"; p. 23) from the two still-operative hagiographic traditions: the French Catholic apologetic tradition and the scientific apologetic tradition. The result is a skeptical biography, full of distrust toward tradition and authority, written very much in the spirit of methodical doubt practiced by its subject.Descartes emerged from a powerful family tradition of law and medicine but mentions his childhood only six times. With good reason. He didn't like either his father or his brother and his mother died thirteen months after he was born. He was considered the family failure, not only wasting time in philosophy but squandering his share of the family fortune. He received an excellent eight-year education at the outstanding Jesuit school at La Flèche where he was immediately attracted to the certitude that mathematics offered him. He earned a law degree in Poitiers, spent time in the Army, though not in battle, and refused a judgeship.It was Isaac Beeckman who radically influenced Descartes's future when he awakened him to the possibility of applying mathematics to the problems of natural science. Watson examines sympathetically Descartes's eventual revolt against this father figure. Watson humanizes Descartes greatly when he examines both his relationship with his daughter, Francina, who died of scarlatina at the age of five, and his relationship with the child's mother, Helena Jans. He also rehabilitates the reputation of Helena who has been traditionally maligned by biographers of the philosopher. Here, and elsewhere, he speaks out loudly and clearly against "the denizens of the Saint Descartes Protection Society" who purport that Descartes broke his celibacy just this once. "Actually," writes Watson, "I think Descartes was enough of a scientist that he would have repeated the experiment several times, if only to see if the experience was the same the second and a third time" (pp. 181; 182).In 1628, totally unwilling to get involved in religious squabbles in France and desiring to live in "joyful anonymity," Descartes takes off for Friesland. This constituted a flight from family, social responsibility, and royalist Catholic totalitarian oppression. He moved around often to situate himself at universities where he wanted to do research and to avoid the plague. This great mathematical genius and father of modern philosophy wanted to replace [End Page 465] Aristotelian philosophy and science and thought correctly that it would be easier to get his ideas accepted here. He became friendly with Princess Elizabeth of Bohemia who spoke five languages and astutely critiqued his metaphysics. Despite the myths, neither was in love with the other. She inspired him to write The Passions of the Soul, which, oddly enough, he dedicated to Queen Christina of Sweden. He did, however, dedicate his Principles to Elizabeth. Christina was a bookish intellectual who loved the theater. In 1649, even though he had exhibited a clear dislike of court life, he agreed to be her tutor. He died in Sweden in 1650 during one of the coldest winters ever recorded in Europe.Why did he go to Sweden? He was broke and had little chance for a pension in France. In addition, while he knew the value of his work, he began to think his life might have been a failure. Perhaps he might really enjoy being a courtier after all. Certainly he feared that he would end... (shrink)

RésuméSelon Descartes, la force démonstrative d'une argumentation peut résulter ou bien de l'application des règles universelles de la logique ou bien d'une intuition particulière. Cette doctrine permet d'éviter le reproche de circularité qui est souvent fait à l'égard de certaines argumentations épistémologiques. D'autre part, elle implique le rejet de la méthode du contre‐exemple. L'acception de certaines argumentations en vertu d'une intuition particulière ne crée pas une situation définitive; elle constitue une phase dans la genèse de ce que Bernays a caractérisé (...) comme une évidence acquise.ZusammenfassungNach Descartes kann die Beweiskraft einer Argumentation entweder von der Anwendung der allgemeingültigen Regeln der Logik oder von einer besonderen Anschauung herrühren. Diese Ansicht erlaubt uns, dem Einwand der Zirkelhaftigkeit zu entgehen, welcher öfters gegen gewisse erkenntnistheoretische Argumentationen erhoben wird. Sie erfordert anderseits den Verzicht auf die Methode der Gegenbeispiele. Die Hinnahme gewisser Argumentationen auf Grund einer besonderen Anschauung schafft niemals eine bleibende Situation; sie bildet eine Phase im Zustandekommen dessen, was Bernays als eine erworbene Evidenz charakterisiert hat.According to Descartes, the demonstrative power of an argumentation may result either from the application of the universal rules of logic or from a particular intuition. This doctrine permits us to avoid the reproach of circularity which is often raised as an objection to certain argumentations in epistemology. On the other hand, it implies the rejection of the method of the counter‐example. The acceptance of certain argumentations based on a particular intuition never creates a permanent situation; it rather constitutes a stage in the genesis of what Bernays has characterized as an évidence acquise.

The purpose of this work is to explain how, with the proposition "cogito ergo sum", Descartes contradicts the A axiom from the Theory of knowledge of Leonardo Polo, by accepting the pasivenness of the knowledge and denying it as an operation of knowing an object, in wich the cognizant and the cognizance are one in act.

Tim Fisher examines a troubling misconception about philosophy that he noticed his high school students possessed: that when it comes to philosophy, you can never be wrong. He expected incoming philosophy students to hold this belief, but was surprised to learn that even after completing his course, students still held the belief that philosophy had no wrong answers—that all views are equally reasonable. Fisher began to wonder where he went wrong. To rectify this misconception, Fisher details an exercise that he (...) developed for second graders that forces students to justify their beliefs and teaches them to examine why one claim is more or less reasonable than another; the exercise is equally appropriate for high school students. The key to this exercise is to teach students to detach personal opinions from their reasoning. (shrink)

Descartes and Hume share at least one fundamental philosophical belief, and that is the proper mindset required in order to begin philosophizing in an orderly manner. Each holds that, once this mindset is achieved, the reader will readily accept the procedures and conclusions that follow. I propose to show that Descartes and Hume argue for the identical starting point for doing philosophy. However, despite this agreement between them, Hume rejects Descartes' teachings, even in regard to the Cogito ergo (...) Sum. I attempt to show why Hume rejects Descartes' account of the Cogito.

[On Hintikka’s Alternative Interpretation of “Cogito, ergo sum”.].

On montre comment, dans le Cogito ergo sum, l’idée de mon existence, en tant que je pense, est liée à l’idée de mon existence en tant qu'être pensant. Ainsi se fait voir la compatibilité du caractère originaire de cette connaissance d’une existence avec la prééminence de la proposition universelle : pour pouvoir penser, il faut exister. De la recherche sur le rapport du cogito ergo sum avec le principe de clarté et de distinction il résulte que (...) le cercle reproché à la démonstration cartésienne n’existe pas. Un développement critique sur le spiritualisme cartésien reste réservé. (shrink)
