My dissertation has two main parts. In the first half, I draw out an underlying presupposition of Descartes' philosophy: what I term "atomism of thought." Descartes employs a radical procedure of doubt in order to show that the first principle of his philosophy, the cogito, is an unshakeable foundation of knowledge. In the dialogue that follows his dissemination of the Meditations, Descartes reveals that a whole set of concepts and rational principles innate in our minds are never doubted. These fundamental (...) units of thought are indivisible, distinct, and isolated, and enable the possibility of any rational demonstration. Atoms of thought are perfectly individuated because God has created them as such. Likewise, our minds have been fashioned such that we necessarily have a clear and distinct perception every time we alight upon these simple notions. In the second part of the dissertation, I take up critiques of Descartes' view given by Nietzsche and Heidegger. In the chapter on Nietzsche, I attempt to fill a lacuna in scholarship about Nietzsche's commentary on Descartes. More specifically, I argue that once the foundation of God is displaced, the basis for accepting atomism of thought dissolves. In the final chapter, I analyze Heidegger's critique of Cartesian atomism. I first look at Heidegger's critique of classical truth as correspondence from Being and Time, and show how it is relevant to a critique of atomism. Then I show how the early Heidegger's holistic philosophical framework can provide an alternative that avoids the pitfalls of atomism. While I limit the scope of my analysis to Descartes' particular formulation, atomism of thought was an influential doctrine throughout modern philosophy. This aspect of Cartesianism has persisted and continues to be a significant theoretical underpinning of many contemporary views. It is my contention that Nietzsche and Heidegger have important contributions to make to this area of thought, and the relative neglect of their work in recent scholarship is a detrimental oversight.

Descartes’s most extensive discussion of the law of refraction and the shape of the anaclastic lens is contained in Rule 8 of "Rules for the Direction of the Mind". Few reconstructions of Descartes’s discovery of the law of refraction take Rule 8 as their basis. In Rule 8, Descartes denies that the law of refraction can be discovered by purely mathematical means, and he requires that the law of refraction be deduced from physical principles about natural power or force, the (...) nature of the action of light, and the behavior of light rays in a variety of transparent media. For over a century, however, there has been broad agreement that Descartes discovered the law of refraction by purely mathematical means, and that he only later provided the relevant physical rationale (via comparisons or analogies) in Dioptrics II. I execute each step in Descartes’s proposed deduction of the law of refraction and the shape of the anaclastic lens in Rule 8 and concretely show how Descartes could have discovered the law of refraction and the shape of the anaclastic by its means. Rule 8, I argue, reflects Descartes’s actual path to the discovery of the law of refraction and the shape of the anaclastic lens. (shrink)

Existing accounts of Foucault’s archaeological methodology have not (a) contextualized the concept properly within the intellectual field of its emergence and (b) explained why it is called ‘archaeology’ and not simply ‘history’. Foucault contributed to the field of ‘history of systems of thought’ in France around 1960 by broadening its scope from the study of scientific and philosophical systems into systems of ‘knowledge’ in a wider sense. For Foucault, the term ‘archaeology’ provided a response to new methodological questions arising from (...) this initiative. Archaeological methodology had already been developed into a distinct comparative approach for the study of linguistic and cultural systems, notably by Dumézil. Foucault redevised archaeological methodology for the post-Hegelian tradition of studying ‘problems’ prevalent in the history of systems of thought. The article thus furnishes the groundwork for a ‘sociological archaeology’ or ‘problem analysis’ that is not particularly dependent on Foucault as a social theorist of power. (shrink)

Generalmente los comentadores han abordado la temática de la intuición en la filosofía de Spinoza desde la perspectiva de la problemática de lo que en la Ética aparece como ciencia intuitiva o tercer genero de conocimiento. En el presente artículo, en cambio, intentamos mostrar que hay en los escritos de Spinoza un concepto de intuición más amplio que el que está implícito en la ciencia intuitiva, del cual esta no sería más que una subespecie. Como paso previo para alcanzar dicho (...) fin, intentaremos mostrar que la concepción de la intuición que sostiene Spinoza está estrechamente emparentada con la concepción cartesiana -de la cual ofrecemos un breve esbozo en el primer apartado- y que ambas concepciones tienen como fundamento la naturaleza de la idea. Generally, critics had tackle the issue of intuition in Spinoza’s philosophy from the point of view of the problem of what in the Ethics is called intuitive science or third kind of knowledge. In the present paper, instead, we try to show that there is in Spinoza`s writings a wider concept of intuition than that which is implied in the intuitive science, being the later no more than a sub-kind of the former. As a previous step to achieve this target, we try to show that Spinoza`s conception of intuition is narrowly tied with the Cartesian conception -of which we offer a brief draft in the first part- and that both conceptions are based on the nature of the idea.

Descartes afirma que el cogito se "experimenta en uno" (apud se experiatur)o se "siente en uno mismo" ("il sent in lui-même"), pero también ha señalado que uno no siente sino a través del cuerpo. El problema es que, en las Meditaciones, el cogito fue caracterizado cuando todavía no se había demostrado la existencia del cuerpo. Pese a esto, Descartes parece haberse dejado influir por ciertas sensaciones internas de duda y certeza. En el trabajo se sostiene que esto fue posible porque (...) esas sensaciones internas son efecto de una ratio implícita: la existencia de un Dios no engañador. (shrink)

This paper examines Descartes's third primary notion and the distinction between different kinds of knowledge based on different and mutually irreducible primary notions. It discusses the application of the notions of clearness and distinctness to the domain of knowledge based on that of mind-body union. It argues that the consequences of the distinctions Descartes is making with regard to our knowledge of the human mind and nature are rather different from those that have been attributed to Descartes due to the (...) influential Rylean picture of Cartesian mind-body dualism.

The concept of continuous creation is now widely used in the context of reflections on the dialogue between science and religion. The first part of this research work seeks to understand its meaning through a twofold elaboration: (1) the historical setting of the three philosophical trends in which this concept was developed: scholastic (conservation), Cartesian (conservation through repetition of the creative act at each instant), and dynamic (interpreting the emergence of radical and contingent novelty in nature as a sign of (...) the continuity of creation); (2) a philosophical and theological critique of the concept of continuous creation regarding the question of the relationship between change and creation, in the light of its highly polymorphous contemporary use, and, in opposition, its absence within the Catholic Magisterium. This work opens the field a further step toward reflection on a renewed concept of continuous creation. (shrink)

In the recently discovered Cambridge manuscript, widely regarded as an early draft ofRules for the Direction of the Mind, Descartes does not describe the mind as a ‘purely spiritual’ force ‘distinct from the whole body’. This has led some readers to speculate that Descartes did not embrace mind-body dualism in the Cambridge manuscript. In this article, I offer a detailed interpretation of Descartes's mind-body dualism in the established Charles Adam and Paul Tannery edition ofRules, and argue that, while differences between (...) the Cambridge manuscript and the established version ofRulesare significant, the relevant passages in the Cambridge manuscript preclude interpretation along both materialist and hylomorphic lines. I then offer an account of the development of Descartes's mind-body dualism between the Cambridge manuscript and the established version ofRules. What the Cambridge manuscript reveals is not Descartes before dualism, but rather Cartesian dualism in its barest form. (shrink)

Did Descartes manage to overcome the skeptics? If we understand “overcome” in the sense of “refute,” the answer is no, since his hyperbolic doubt harbors several blind spots and is, therefore, not as radical as is commonly argued. In this way, the victory of the cogito is perhaps less decisive and fruitful than it is claimed. If we understand “overcome” in the sense of “remove” or “move beyond,” the answer is yes. Descartes has overcome skepticism, but at the cost of (...) a decision, a sort of bet made in favor of reason based on a confidence in the human mind that is never really subverted. This faith in reason, truth, and specific epistemological principles in Descartes’ philosophy constitute what Wittgenstein calls “hinges,” which are indispensable for doubting and searching for truth. In this sense, Descartes’ anti-skepticism is more a confidence in reason in order to save the possibility of science than the result of a logical refutation. (shrink)
