René Descartes

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.

Argues that Descartes's commitment to mind-body causation leads to a commitment to body-body causation.

In Meditation I, Descartes dismisses the possibility that he might be insane as a ground for doubting that the senses are a source of knowledge of the external world. In this paper, I argue that Descartes was justified in so doing, and draw some general epistemological conclusions from this result.

Descartes argues that, apart from the existence of a veracious God, we can have no reason to believe that we possess reliable cognitive faculties, with the result that, if atheism is true, not even our seemingly most certain beliefs can count as knowledge for us. Since the atheist denies the existence of God, he or she will be precisely in this position. I argue that Descartes' argument is sound, and that atheism is therefore self-refuting.

This paper contests a standard interpretation of how Descartes comes to the conclusion that he is not his body in the second meditation. I propose an alternative interpretation in its place.

Charles Larmore presents the central part of Descartes’ first meditation as a brief dialogue between a skeptic and a sensible empiricist. I point out a source of discontent about this innovative transformation.

I raise the question of whether there is a hidden source of doubt in Descartes’ first meditation, if one adopts the perspective of some people he describes as insane.

In this paper, I present the problem of the poor king, from combining Descartes and Rousseau.

The purpose of this essay is to exhibit in detail the setting for the version of the Cogito Argument that appears in Descartes’s Meditations. I believe that a close reading of the text can shed new light on the nature and role of the “evil demon”, on the nature of God as he appears in the first few Meditations, and on the place of the Cogito Argument in Descartes’s overall scheme.

In May 1643 Elisabeth of Bohemia addressed a question to Descartes which inaugurated a six-year Correspondence, until his death. He dedicates his mature metaphysical work to the Princess (Principles of First Philosophy, 1644) and writes Passions of the Soul (1649) as one of the results of the dialogue with the philosopher of Bohemia. The silencing of the last hundred years of historiography on Elisabeth of Bohemia's legacy in this epistolary exchange caused distortions and, in some cases, underpinned the bias as (...) a rule and as the history. One of the consequences of this distortion is the interpretation according to which her first question would consist of a critique of substantial dualism. In this study I suggest an interpretation of the nature of the first question, in order to clarify the philosopher's thinking and her role in dialogue, in a comprehensive way, without subscribing to the literary paradigm of the Cartesian soliloquy, and its bias.

In this work I intend to explore the textual and conceptual roots of the moral view in the Early Modern Rationalism of Cartesian spectrum as detected by Elisabeth of Bohemia. To this intent, I will drive my analysis, first, to the remark Descartes adds to his own provisional morality of the Discourse in the Letter of August 4th, 1645 to Elisabeth. Second, I will approach the two aspects of her reply to Descartes, both in her Letter of September 13th 1645, (...) which I call a) the contextual aspect – with which she excludes the hypotheses of an infinite science at the service of assessing the good and b) the self-related aspect, with which the philosopher of Bohemia address the moral objectiveness as an intrinsic practical value, obtained by the passions that may lead to reasonable actions. The upshot is a practical and affective moral view, in which the normative trait of some passions of the soul can be taken as the explanation of an intentional infrastructure of the mind, without, however, a theory of ideas as such playing an explicit role. Instead of a representational endeavor, Elisabeth of Bohemia claims a kind of self-awareness from the discovery of a passionate function as an expression of the adequate measure between happiness and morality of actions. That kind of awareness, I shall demonstrate, is what objectiveness consists in. (shrink)

Bernard Williams argued that historical and philosophical inquiry were importantly linked in a number of ways. This introductory chapter distinguishes four different connections he identified between philosophy and history. (1) He believed that philosophy could not ignore its own history in the way that science can. (2) He thought that when engaging with philosophy’s history primarily to produce history, one still had to draw on philosophy. (3) Even doing history of philosophy philosophically, i.e. primarily to produce philosophy, required a keen (...) sense of how historically distant from us past philosophers were, on his view, because the point of reading them was to confront something different from the present. (4) He held that systematic philosophy itself needed to be done historically, engaging not necessarily with its own history, but with that of the concepts it sought to understand. The chapter closes with an overview of the volume’s structure and content. (shrink)

This paper offers an analysis of Johannes Swammerdam’s researches on the brain of the honeybee (Apis mellifera), on the basis both of his published texts and of (1) an early, manuscript version of his treatise on bees (broadly intended) (1673), and (2) a hitherto unedited autograph of his, containing the earliest depiction and description of an insect brain (1673–1677). Through a reconstruction of the genesis of Swammerdam’s texts on bees, both the novelty and accuracy of his observations are highlighted, as (...) well as his reliance on a Cartesian physiology in the interpretation and rendering of the observed parts.

In this paper I provide a commentary on and edition of the unpublished and apparently incomplete Medicina contracta of the Flemish philosopher Arnold Geulincx (1624– 1669). This short treatise, dating to c. 1668–1669, was not included in the edition of Geulincx’s works edited by J.P.N. Land, on the ground of its apparent unoriginality. However, it reveals the attempt, by Geulincx, to develop a medicine based on a new account of disease (intended in Cartesian-Platonic terms of the impossibility of the mind (...) using the body through animal spirits), and integrating avant-garde solutions typ- ical of iatrochemistry (in particular those of Franciscus Sylvius) and iatromechanics. The text, which I also consider in the light of Geulincx’s disputations in physiology, is moreover revelatory of his ongoing efforts in understanding the nature of respiration and its related diseases and conditions, such as apoplexy, and of his progressive, albeit not uncritical acceptance of Cartesianism.

In this paper I provide an analysis of an anonymous text which appeared at Sondershausen and Mühlhausen in 1687: Initiatio philosophi sive Dubitatio Cartesiana, ad indubiam philosophiam viam monstrans, iuxta mentem Renati des Cartes, Nobilis Galli, utraque methodo explicata, titled after Johannes Clauberg’s homonymous 1655 treatise. It consisted of (1) an abridgement of his Paraphrasis in Renati Des Cartes Meditationes (1658), and (2) a demonstration more geometrico of the necessity of methodical doubt as the beginning of philosophy, partially based on (...) Clauberg’s own 1655 Initiatio. I place the publication of the 1687 text in the context of the attacks on Cartesianism taking place in German areas especially after 1677 and the appearance of Spinoza’s texts, focusing on the ways in which Clauberg’s philosophy was adapted to the rebuking of such attacks and to the re-establishment of a Cartesian presence in Germany.

The important philosophers in history aren’t all that great. First, their works are full of bad arguments, confused concepts, falsehoods, implausible claims, and lack of clarity. We can see this by using a “peer-review test,” which asks us to evaluate these claims and arguments as if they were submitted to us as anonymous work. Second, I make the case that canonizing some philosophers as great is damaging to the philosophical project of seeking truth regardless of its source. I suggest an (...) alternative hypothesis. The putatively great philosophers were just intelligent individuals who had the right ideas at the right time. They are worth reading not because of their intellectual genius but rather for their creativity and insight, offering novel solutions to certain problems and noticing implications others had missed. Accordingly, my position does not entail that the “great” figures are of no philosophical interest. However, we should do away with the idea of a “great philosopher.” Philosophy might then come to resemble other disciplines that seek the truth, which generally do not revere their historically important predecessors.

Recent historiography has shown that Descartes remains a prominent figure in philosophical discourse and that a multitude of prejudices have arisen around his persona, which have contributed over time to the creation of an often stereotyped and, in some cases, distorted image of him and his most famous and influential doctrines. It is therefore essential to take stock of the state of historiographical research on Descartes in recent years. In this context, I have tried to draw attention to some recently (...) published volumes, with the aim of enabling the reader to approach the study of this great philosopher with greater awareness. This can be achieved both through the author’s internal analysis of his work and the comparison with other philosophers and scholars who were his contemporaries. (shrink)

Honouring the memory of the late Bernard Stiegler, this edited collection presents a broad spectrum of contributions that provide a complex and coherently articulated image of Stiegler's thought which reached beyond the boundaries of academic, artistic and experimental techno-scientific enclaves where it had been originally received. -/- Stiegler's philosophical work encompassed theorization, social diagnosis, planning, practical and territorial experimentation, politics, and aesthetics. In its wake, the essays in this volume celebrate and explore the wealth of this multi-dimensional legacy. They examine (...) the conditions of human life in general, its foundational intermittence, and carry forward Stiegler's post-phenomenological unfolding of the distinctive spatio-temporalities that weave together the epoch we call 'present'. Engaging closely with Stiegler's original impetus for the creation of technologies of care, as well as of communities of knowledge and artistic practice,. (shrink)

This paper discusses an anonymous manuscript Dissertatio against Descartes’s and Gassendi’s theories of knowledge, dating from the first half of the eighteenth century and now preserved in the Biblioteca Forteguerriana in Pistoia. It is probably the result of Jesuit pedagogy, stemming from the lectures in which Aristotle’s works were commented on, drawing heavily on the doctrine of Thomas Aquinas.

A partir del libro De la filantropía a las pasiones, publicado en 1994, en el presente texto se reflexiona sobre varios temas poco estudiados en la fi-losofía de Descartes: la libertad, la moral, la experiencia, la estética, etc. Primero se realiza una nota sobre el contexto de la obra de Descartes para resaltar el carácter moral de su filosofía. A continuación, se analiza el concepto de libertad en Descartes y se ponderan dos interpretaciones de este, a saber: la de Leiser (...) Madanes y la de Laura Benítez. Se brindan razones para sostener que la libertad esclarecida tiene más valor, para Descartes, que la libertad de indiferencia. Finalmente, se problematiza el contenido del Compendium musicae a partir del vínculo entre el cono-cimiento del mundo externo y la libertad en Descartes. (shrink)

Descartes’ first book, 1618’s Compendium of Music, focuses on biomechanical reactions in the human body but also claims that the purpose of art is to arouse emotions. By the end of the 1630s, however, he had given up on precisely predicting how that arousal may occur. This article contends, though, that Descartes’ abandonment of that project is a result of using an inappropriate psychological model for such predictions. An appropriate model is developed in his last book, 1649’s The Passions of (...) the Soul. Especially by attending to generosity and desire, the probability of predicting aesthetic judgments is at least increased. In increasing it, Descartes’ abandonment need not be total. (shrink)

This article argues that Clauberg defends the theory of concurrentism concerning the relationship between divine and secondary causality. It does so by examining Clauberg's theory of corporeal causation in light of his doctrines of cause in general and of corporeal substance. Clauberg's work represents one of the first attempts to reconcile Cartesian physics with the traditional doctrine in theology, according to which both God and created substances are true and immediate causes of all natural effects, in opposition to the occasionalist (...) trend which would soon develop in the Cartesian school as well as to the conservationist alternative of Durand de Saint-Pourçain. -/- Cet article soutient que Clauberg défend la théorie du concurrentisme sur la relation entre la causalité divine et la causalité seconde. Il le fait en examinant la théorie de la causalité corporelle de Clauberg à la lumière de ses doctrines de la cause en général et de la substance corporelle. L'œuvre de Clauberg représente l’une des premières tentatives de réconcilier la physique cartésienne avec la doctrine théologique traditionelle, selon laquelle Dieu et les substances créées sont des causes vrais et immédiates de tout effet naturel, en opposition au courant occasionnaliste qui se développera bientôt dans l'école cartésienne ainsi qu'à l'alternative conservationniste de Durand de Saint-Pourçain.

Since Antoine Faivre's emergence and establishment of "Western esotericism" in the late twentieth century, the discourse of globalising esotericism (beyond the West) has been fraught with controversy. As there are several polemical conversations about how such an effort should manifest itself in esoteric scholarship. This comparative, descriptive, and religionist approach to esotericism explores the intricate relationship between sexuality and spirituality by understanding the intersections of these aspects as manifested in Western, Eastern, and African esoteric currents, from Aleister Crowley's magia sexualis (...) to Marie Laveau (The Widow Paris)'s "Gris-Gris". Firstly, this is achieved by bringing said geographical regions into dialogue with one another, determining how esotericism fits into the overall trajectory of the origins of religion. Secondly, delving into the polemics and history of sexuality: from Foucault to Freud. Thirdly, positioning an esoteric spirituality in the digital era. Consequently, through identifying currents in the West, East, and Africa: including Paganism, Thelema, Satanism, New Age, and Theosophy in the West and Egyptian Paganism, Hinduism, and Buddhism in the East, in addition to African Traditional Religion (ATR), Sufi Islam, and Afro-American "Conjure" in Africa. This study, when intersected with philosophical conceptualisations of the self, contributes to a novel understanding of sexuality as sacred post-theistic (self-) spirituality, with esotericism serving as the foundation for such an approach.

The third Meditation is typically understood to contain two a posteriori arguments for the existence of God. The author focuses on the second argument, where Descartes proves the existence of God partly in virtue of proving that Descartes cannot be the cause of himself. To establish this, Descartes argues that if he were the cause of himself, then he would endow himself with any conceivable perfection. The justification for this claim is that bringing about a substance is more difficult than (...) creating an attribute, so anything that can do the former can do the latter. While current explanations of this justification are either implausible or inadequate, the author argues that this principle derives support from a scholastic distinction between being-as-such and determinate being. With this distinction in view, we can make sense of Descartes's argument without appealing to ambiguous or inadequate notions. (shrink)

First published as 「デカルト哲学について」 in June 1944. The essay is included in 『西田幾多郎全集』 [Complete Works of Nishida Kitarō] (Tokyo: Iwanami Shoten, 2002–2009 ), 10: 117-49.

To Stiegler’s notion of pansable (curable), one might also need to add that penser (to think) relates to the Latin penso, the frequentative of pendo, to hang, suspend. The pansable (that which can be healed) is as much the pensable (that which can be thought) and the suspensible (that which can be hung). Stiegler’s final act revealed that which was always already there: an unhealed pharmacological shadow that preceded him. While he entered philosophy with the argument of technics as the (...) impensé (unthought) of continental philosophy, he concluded in a final acting out, an impansable (uncurable) that ended his life. He, who believed that life is about cultivating rêveries and protentions capable of promise. Protention means both a capacity to invent and an ability to project oneself into the future through the practice of imagination and desire. He, who pondered about the retentions we have and the various forms of memory they take, and how to make them become the true modes of being-in-the-world. I know now that his fatal transgression is as much an accident as a departure, an emotional ceasefire and a bifurcative ending. Somehow, he found a way to remain faithful to the originary beginning of his thinking in act. (shrink)

How can we know we are not dreaming? In this essay, I tackle this and related questions from a transcendental standpoint, by building a philosophical narrative centred upon three “giants”: Descartes, Kant, and Putnam. From each, I take some ideas and discard others, to develop a historically informed, yet original, transcendental approach to dream skepticism.

The problem of alterity can be posed in two areas: a) that of absolute alterity, which Descartes develops in the Third Meditation when the ego discovers himself as a negation of infinite and an aspiration to the infinite; b) that of relative alterity that distinguishes me from my fellow man. Firstly, we risk a synthesis of the ways in which the alter ego loses his otherness when conceived as an object of representation or desire. Secondly, we propose that Descartes thinks (...) of alterity in a purely ethical sense, as a capacity for good and evil. Our thesis is, first: pure love (without desire) is parental love —the only one addressed to others themselves for themselves, the only one that opens the possibility of self-giving, sacrifice. Second, we propose that Descartes’ texts acquire all their meaning if they are compared with the ethical notion of alterity in the philosophy of Emmanuel Levinas. -/- El problema de la alteridad puede plantearse en dos ámbitos: a) el de la alteridad absoluta, que Descartes desarrolla en la Tercera Meditación cuando el ego descubre su finitud como una negación y una aspiración de infinito; b) el de la alteridad relativa que me distingue de mi semejante. En primer lugar, arriesgamos una síntesis de los modos en que el alter ego pierde su alteridad al ser concebido como objeto de representación o de deseo. En segundo lugar, proponemos que Descartes piensa la alteridad en sentido puramente ético, como capacidad de bien y de mal. Nuestra tesis es, primero: el amor puro (sin deseo) es el amor paterno —el único dirigido al otro sí mismo por sí mismo y que abre la posibilidad de la donación de sí, el sacrificio; segundo: los textos de Descartes adquieren todo su sentido si se los compara con la noción ética de alteridad en la filosofía de Emmanuel Levinas.

This essay investigates the way in which Wolff takes an interest in the hypothesis of an emendatio of the prima philosophia from Leibniz’s incitement in De primae philosophiae emendatione, et de notione substantiae (1694) to re-found metaphysics. This makes it possible, secondly, to examine the way in which Wolff takes Johannes Clauberg’s ontology as a model, even though it represents in his view only a failed attempt at that same emendatio. Through the analysis of the texts, this article considers the (...) possibility of a new reading of the ‘failure’ attributed by Wolff to Clauberg, which would consist in his having ‘emended’ first philosophy by expelling it from the domain of ontology and finally identifying it with Cartesian prima philosophia.

This essay defends two theses regarding the explanation, or ground, of modality in the early modern period. First, for philosophers in the period, essences ground a range of important modal facts. Second, as the period progresses, we witness increased skepticism about certain modal facts, due to a growing skepticism about the scope or existence of essences. These theses are supported by examination of three case studies: Descartes’ treatment of substance and mode (which forms the core of his ontology); Malebranche’s treatment (...) of causation (which bears on his defense of occasionalism); and Locke’s treatment of necessary connections among properties (which is related to his accounts of individuals and kinds). It is shown that in each case, claims about necessity and possibility take center stage, and that in each case, the status of these claims hinges on the status of claims about essences. (shrink)

This article aims to establish that Descartes accepted the scholastic view that God’s duration in itself (“eternity”) is not successive but “all at once,” as opposed to temporal things’ durations. Though most scholars have assumed this to be Descartes’ view, Geoffrey Gorham recently called it into question with a number of strong arguments. We contest his interpretation on multiple grounds. First, we show that when Descartes asserts that a duration which is “all at once” is “inconceivable,” he is not making (...) a metaphysical claim but, rather, is making an epistemological one, based on the limitations of the human intellect in understanding the attributes of God. Second, we object to a number of Gorham’s systematic reconstructions of Descartes’ views. He argues among other things that divine simplicity is consistent with temporal parts and that the laws of Cartesian physics require God to have temporal parts. We refute these claims based on Descartes’ fundamental metaphysical commitments. We thus conclude that Descartes does not think that, per se, God’s existence unfolds successively, moment after moment. (shrink)

This paper offers a reconstruction of the interpretations of Descartes's ideas of place and motion by Dutch Cartesians (Henricus Regius, Johannes de Raey, Johannes Clauberg, and Christoph Wittich). It does so by focusing on the reading of Descartes's Principia philosophiae (1644) offered, in particular, by the dictated commentaries on it. It is shown how such commentaries bring to the light new potential Aristotelian-Scholastic sources of Descartes, and the different ways Dutch Cartesians brought to the fore, also with the help of (...) such sources, the rationale of the Cartesian text: in doing so, they constituted a philosophical school.

In this paper I argue that, contrary to what one might think, early modern rationalism displays an increasing and well-grounded sensitivity to certain metaphysical questions substantial form was designed to answer—despite the fact that the notion itself was in such disrepute, and emphatically banished from natural philosophy. This main thesis is established by examining the thought of Descartes, Spinoza, and Leibniz through the framework constituted by what have been designated as the two aspects, metaphysical and physical, of substantial form. This (...) examination shows that Descartes ends up assigning to soul a notable metaphysical task formerly assigned to substantial form, whereas Spinoza advances a theory of essences motivated by the philosophical concerns behind the two aspects of substantial form. Leibniz finally makes a sharp distinction between natural philosophy and metaphysics as he develops a dynamistic theory that deliberately aims at understanding substantial form in a new fashion. This line of development is designated as one major factor contributing to the separation of philosophy and natural science. (shrink)

Prof. Dr. Mehmet Karasan 1907 yılında Denizli, Çivril’de doğdu . İlk ve orta öğrenimini Çivril ve Konya’da, lise eğitimini 1928 yılında İstanbul Erkek Lisesi’nde tamamladıktan sonra aynı yıl Millî Eğitim Bakanlığı’nın yurt dışı eğitim bursunu kazanarak Fransa, Lyon Üniversitesi, Edebiyat Fakültesi, Felsefe ve Sosyoloji bölümünde lisans eğitimi almaya hak kazandı. 1932 yılında yurt dışı eğitimini tamamlamasının ardından 1933 yılında İstanbul Üniversitesi Felsefe Bölümüne doçent olarak atandı. 1942 Yılında İstanbul Üniversitesi Felsefe Bölümü asistanı Nusret Hızır ve pedagoji doçenti Bedii Ziya Egemen (...) ile birlikte Ankara Üniversitesi Dil ve Tarih-Coğrafya Fakültesi Felsefe Enstitüsü kadrosuna katıldı. 1932-1950 yılları arasında belirli dönemlerde çeşitli okullarda felsefe, sosyoloji ve Fransızca öğretmenlikleri ve idarecilik yapan Karasan 1951 yılında Ankara Üniversitesi İlahiyat Fakültesi’nde Profesör olarak göreve başladı. Prof. Dr. Mehmet Karasan akademik hayatının yanı sıra 1954-1957 ve 1957-1960 yılları arasında X. ve XI. dönem Türkiye Büyük Millet Meclisi’nde Denizli Milletvekilliği yaptı. Siyasi hayatının ardından 1968 yılında Ankara Üniversitesi İlahiyat Fakültesi felsefe kürsüsünde Profesör olarak akademik yaşamına devam etti ve 1970-1971 yılları arasında aynı fakültede dekanlık görevinde bulundu. 15 Kasım 1974 tarihinde hayatını kaybeden Karasan Evli ve bir çocuk babasıydı. Mehmet Karasan Türk düşüncesine ve literatürüne Eflatun’un Devlet Görüşü (1947) ve Büyük Feylesoflar Antolojisi (1949) adlı kitapları, “İlk Yunan Düşüncesinde Din İlmi Denemeleri” ve “Eflatun’un Devleti” gibi makaleleri ile katkıda bulundu. Karasan, Fransa’da almış olduğu yurt dışı eğitiminin etkisi ve Cumhuriyet döneminde 1940 yılında Hasan Ali Yücel tarafından başlatılan “Tercüme Hareketi” vesilesiyle yabancı dilde yazılan birçok klasik eseri tercüme ederek dilimize kazandırdı. Platon, Descartes, Durkheim ve Bergson gibi önemli filozofların eserlerini tercüme ederek felsefe alanına önemli katkılarda bulunan Karasan, Durkheim’ın Meslek Ahlakı kitabını tercüme etmesi ve “Din Sosyolojisi, Öncüleri ve Kurucuları” başlıklı bir makale kaleme alması ile yalnızca felsefe alanına değil sosyoloji alanına da önemli katkılarda bulundu. Bu sayede Cumhuriyet döneminde akademik anlamda Türkiye’de ilk din sosyolojisi dersini 1949 yılında Ankara Üniversitesi İlahiyat Fakültesinde verdi. Karasan sosyolojiye yönelik çalışmaları ile birlikte özellikle felsefe alanında Descartes’ın İlk Felsefe Üzerine Metafizik Düşünceler (1942), Felsefenin İlkeleri (1943), Aklını İyi Kullanmak ve Bilimlerde Doğruyu Bulmak İçin Metot Üzerine Konuşma (1944), Tabiat Işığı ile Hakikati Arama (1945), Aklın İdaresi İçin Kurallar (1945) ve Ahlak Üzerine Mektuplar (1946) gibi birçok eserini Fransızcadan dilimize tercüme etmesi ve yapmış olduğu bu tercümelere eklemiş olduğu ön sözler ve açıklamalar ile Türkçe felsefe alan yazınında tanınırlık kazandı. Descartes’ın eserleri ile birlikte Fransızca’dan dilimize kazandırdığı eserler arasında Bergson’un Ahlak ile Dinin İki Kaynağı (1949), Lucien Laberthonnière’in Descartes Üzerine Tetkikler (1959) eseri ve bir dönem Ankara Üniversitesi Dil ve Tarih-Coğrafya Fakültesi Felsefe kürsüsünde görev yapan Olivier Lacombe’un bazı makaleleri de bulunmaktadır. Böylece, Mehmet Karasan Descartes’ın felsefesi başta olmak üzere Fransız düşüncesi ve felsefesinin Türkiye’de tanınması açısından önemli bir görevi yerine getirdi. Prof. Dr. Mehmet Karasan Türkiye Cumhuriyeti’nin görece ilk yılları sayılabilecek dönemi içerisinde sorumluluk alarak felsefe ve edebiyat alanında hem tercüme faaliyetleri hem de kendi özgün eserleri ile Türk düşüncesinin ve felsefesinin gelişimine yardımcı olan bir düşünürdür. Karasan’ın başta Fransız felsefesi olmak üzere felsefeye yönelik düşüncelerinin günümüz entelektüel çevresi ve araştırmacıları tarafından tanınması önem teşkil etmektedir. Ancak Mehmet Karasan’ın düşünce hayatı, felsefi görüşleri ve felsefeden ne anladığına yönelik yapılan çalışmaların azlığı ve eserlerine ulaşmanın zorluğu göz önünde bulundurulduğunda onun yaşamı ve felsefesine yönelik mevcut bilginin eksikliği göze çarpmaktadır. Bu nedenle Mehmet Karasan’a yönelik bir çalışma ortaya koyma gerekliliği ortaya çıkmaktadır. Bu gereklilik doğrultusunda yazımızda Karasan’ın ortaya koymuş olduğu çalışmalarının seyri ve gelişimi takip edilerek görüşleri aktarılmaktadır. Bu noktada onun tercüme eserlerine yazmış olduğu ön sözler ve açıklamalar dikkate alınmaktadır. Böylece, Karasan’ın özellikle Descartes’tan yaptığı tercümelerden hareketle onun felsefi yaklaşımına ve felsefeden ne anladığına ilişkin bir tahlilde bulunulmaya çalışılmaktadır. Belirtmek gerekir ki bu yazının temel amacı Descartes’ın felsefesini ya da felsefi görüşlerini aktarmak değil Mehmet Karasan’ın Descartes’ın felsefesine yönelik okumaları, çıkarımları, düşünceleri ve katkılarını tespit ederek kendi özgün düşüncelerini ve felsefi tavrını ortaya koymaktır.

This article examines how deduction preserves certainty and how much certainty it can preserve according to Descartes’s Rules for the Direction of the Mind. I argue that the certainty of a deduction is a matter of four conditions for Descartes. First, certainty depends on whether the conjunction of simple propositions is composed with necessity or contingency. Second, a deduction approaches the certainty of an intuition depending on how many “acts of conceiving” it requires and—third—the complexity or difficulty of the acts (...) of thinking, which is determined by the content of the thoughts and on external factors. Fourth, certainty depends on the intellectual aptitude of the person using the deduction. A deduction lacks certainty when it relies on memory such that it is not apprehended with immediacy. However, the mental capacity and speed of a mind can be increased by training the special mental faculties of perspicacity and discernment. Increasing one’s intellectual aptitude allows for more steps of a deduction to be inferred in fewer acts of conceiving, thereby helping preserve the certainty of a deduction. (shrink)

Self-verifying judgments like _I exist_ seem rational, and self-defeating ones like _It will rain, but I don’t believe it will rain_ seem irrational_._ But one’s evidence might support a self-defeating judgment, and fail to support a self-verifying one. This paper explains how it can be rational to defy one’s evidence if judgment is construed as a mental performance or act, akin to inner assertion. The explanation comes at significant cost, however. Instead of causing or constituting beliefs, judgments turn out to (...) be mere epiphenomena, and self-verification and self-defeat lack the broader philosophical import often claimed for them.

Descartes was the first to hold that, when we perceive, the representation need not resemble what it represents but should correspond to it. Descartes developed this ground-breaking, influential conception in his work on analytic geometry and then transferred it to his theory of perception. I trace the development of the idea in Descartes’ early mathematical works; his articulation of it in Rules for the Direction of the Mind; his first suggestions there to apply this kind of representation-by-correspondence in the scientific (...) inquiry of colours; and, finally, the transfer of the idea to the theory of perception in The World.

The attention paid in the Giornale critico della filosofia italiana to the major exponents of seventeenth-century philosophical rationalism, from its foundation by Giovanni Gentile in 1920 until 1979, reveals important changes that provide us with interesting information on Italian Neo-idealism. The small number of articles on Descartes can be interpreted as the result of an overall approach – sanctioned by Gentile – different from that of Hegel, who considered Descartes as the founder of modern philosophy. For Gentile, Descartes represents a (...) stage in the history of philosophy spanning from Humanism to Spinoza, and, in a more particular Italian perspective, from Campanella to Vico. This interpretative scheme persisted also under the direction of Ugo Spirito, when Cartesianism continued to receive little theoretical and historical attention, with the exception of Eugenio Garin’s contributions. In the years from 1945 to 1979, the Giornale critico emphasized instead the interest for Spinoza, a very important author for Gentile, up to the double monographic issue published on the occasion of the third centenary of Spinoza’s death (1977). In turn, the lack of interest for Leibniz was constant and evident from the small number of articles published from 1920 to 1979, which were furthermore not particularly connected with the international, coeval Leibniz scholarship.

In arguing against the likelihood of consciousness in non-human animals, Descartes advances a slippery slope argument that if thought were attributed to any one animal, it would have to be attributed to all, which is absurd. This paper examines the foundations of Thomas Willis’ comparative neuroanatomy against the background of Descartes’ slippery slope argument against animal consciousness. Inspired by Gassendi’s ideas about the corporeal soul, Thomas Willis distinguished between neural circuitry responsible for reflex behaviour and that responsible for cognitively or (...) consciously mediated behaviour. This afforded Willis a non-arbitrary basis for distinguishing between animals with thought and consciousness and those without, a methodology which retains currency for neuroscience today. (shrink)

In his Christian and Metaphysical Meditations (1683) Malebranche develops a reflection in which the self discovers in its interiority that the interlocutor able to answer some of its questions is the divine Word. Through references to the Holy Scriptures and to Augustine, Malebranche constructs a meditative itinerary that differs from the one proposed by Descartes, as it moves from the lumière naturelle in the Cartesian sense to the lumière of the Word. In the light of these historical-theoretical data, we propose (...) a reconstruction of the role played by interiority and meditation in certain texts by Malebranche, highlighting the moments in which he appropriated the Cartesian heritage and those in which he distanced himself from Descartes’ philosophical paradigm.

Descartes held that it is impossible to make true statements about what we perceive, but I go over alleged cases of illusory experience to show why such a skeptical conclusion (and recourse to God) is overblown. The overreaction, I contend, stems from an insufficient awareness of the habitual expectations brought to any given experience. These expectations manifest themselves in motor terms, as perception constantly prompts and updates an embodied posture of readiness for what might come next. Such habitual anticipations work (...) best when they efface themselves, so it is easy to blame perception when our expectations get frustrated. I illustrate this misdirected blame with the example of a stick partially in water: it is only because we expect the stick to be straight that its appearance as bent is deemed problematic. I thus conclude that, if we factor in the habitual interpretations operative in perception and switch to a processual view that allows practical engagement, we can deflate the worries that led Descartes to rule out perceptual truths. Distancing myself from the naïve “sign” of folk semiotics, my critique draws inspiration from the triadic semiotic model developed in some late medieval schools of Portugal. (shrink)
