Throughout their life Ibn Sînâ and Descartes firmly believed that the soul or mind of a human being was essentially incorporeal. In his ‘On the Soul’ (De anima), the psychological part of his vast...

This study is the first part of an attempt to settle a vigorous debate among historians of medieval philosophy by harnessing the resources of analytic philosophy. The debate is about whether Avicenna's epistemology is rationalist or empirical. To settle the debate, I first articulate in this article the three core theses of rationalism and one core thesis of empiricism. Then, I probe Avicenna's epistemology in his major works according to the first core thesis of rationalism (the intuition thesis). In the (...) end, I find Avicenna committed to this thesis in at least one substantive way, namely, in his claim to intuit the intelligible forms or essences. This suffices to count Avicenna as rationalist. In a subsequent article, I shall probe Avicenna's epistemology according to the other two core theses of rationalism, presenting further evidence that he was a rationalist, not an empiricist.

Angesichts der in den letzten Jahren intensiv erforschten Abhängigkeiten des Denkens Meister Eckharts von der Kölner Dominikanerschule, vor allem von Dietrich von Freiberg und seiner Intellekttheorie, stellt sich die Frage nach den Begriffen vom Intellekt und von der Gottesschau, die in den Texten Eckharts und in volkssprachlichen Texten seiner Umgebung begegnen. Eine genaue Lektüre dieses Textmaterials läßt erkennen, daß man schon zu Lebzeiten Eckharts von einem Gegensatz zwischen Eckhart und Dietrich ausgegangen ist und die Differenz der Konzepte diskutiert hat. Es (...) geht dabei um ein grundsätzlich verschiedenes Verständnis der Gottesschau und um eine Privilegierung von Bildern der Passivität des Menschen in der Eckhartschule, deren Einfluß bis zu Juan de la Cruz, Friedrich Nietzsche und Ingeborg Bachmann spürbar ist.

This article is about Avicenna’s account of syllogisms comprising opposite premises. We examine the applications and the truth conditions of these syllogisms. Finally, we discuss the relation between these syllogisms and the principle of non-contradiction.

Explicit atheism is a philosophical position according to which belief in God is irrational, and thus it should be rejected. In this paper, I revisit, extend, and defend against the most telling counter arguments the Kalām Cosmological Argument in order to show that explicit atheism must be deemed as a positively irrational position.

Spinoza rarely refers to art. However, there are extensive resources for a Spinozist aesthetics in his discussion of health in the Ethics and of social affects in his political works. There have been recently been a few essays linking Spinoza and art, but this essay additionally fuses Spinoza’s politics to an affective aesthetics. Spinoza’s statements that art makes us healthier (Ethics 4p54Sch; Emendation section 17) form the foundation of an aesthetics. In Spinoza’s definition, “health” is caused by external objects that (...) maintain our power to act in a variety of ways. Humans need such objects because our complex bodies constantly lose or consume many parts necessary to our overall functioning. Notably, Spinoza defines humans’ bodies through this complexity (2p13Sch), so health as maintenance of complexity is a distinctly human endeavor. Further, while art is not the only healthy activity, I argue that art is a particularly potent cure, which explains Spinoza’s otherwise opaque comment that music can cure melancholy (by which he meant a near-total inability to act, akin to death). Rather than only causing frivolous pleasures, art may be as essential to human flourishing as are other human beings in general; other people are “most useful” because of the variety of actions they make possible (4p35Cor & Sch1). Art’s production of a dizzying variety of affects is likewise most useful for health. -/- Having established how art in general affects the individual, I then explain the role of artists in shaping social groups. Artists use vivid and highly charged affective techniques, as do political sovereigns and religious prophets (TTP chapters 1-2 & 15-16). However, sovereigns and prophets are concerned exclusively with “morality,” defined by Spinoza as the use of affects (primarily based on fear and hope) to produce “obedience” in the generic multitude or people at large. An artist, however, rarely causes affects in the whole nation, affecting instead only a smaller niche or “sub-genre” of people. The affects produced in this group are also not identical to those used by sovereigns, since artists do not primarily deploy sad affects of hope and fear but instead use a wide variety of joyful affects. Further, in Spinoza’s analysis of ceremonies (TTP chapter 5), we see how small groups exposed to repeated ceremonies or social practices eventually develop new strengths which they lacked before. Repeated exposure to shared aesthetic “ceremonies” (e.g., live music performances) of the same sub-genre will over time create the capacity of new powers in the sub-genre of people, which distinguishes them from the masses. Spinoza says sovereigns forge a “second nature” for the generic people through affects; we can then affirm that smaller groups exposed to a distinct sub-genre of art can acquire a new “third nature” which will contain unique powers extending beyond healthy maintenance of their existing bodies. That is, art in general is necessary to flourish and remain whole (maintaining health), but it can also occasionally expand what one is to unforeseen heights (through specific artistic sub-genres).

In this paper I examine the question whether Spinoza can account for the necessity of death. I argue that he cannot because within his ethical intellectualist system the subject cannot understand the cause of her death, since by understanding it renders it harmless. Then, I argue that Spinoza could not solve this difficulties because of deeper commitments of his system. At the end I draw a historical parallel to the problem from medieval philosophy.

RésuméLa théorie avicenienne du mouvement des orbes célestes représente un aspect important de sa cosmologie qui n'a cependant pas encore été l'objet d'une étude approfondie. Cet article compte combler ce manque en fournissant une analyse des différents principes à l'origine du mouvement céleste, ainsi qu'une réflexion sur le rôle des disciplines astronomique, physique, et métaphysique dans les explications que fournit Ibn Sīnā à ce sujet. L'accent est mis sur le rapport des intelligences aux orbes et sur la problématique du passage (...) de l'intellectif au physique, un moment charnière dans la cinématique avicenienne. En outre, l'étude remet en question l'adhésion d'Ibn Sīnā à la théorie farabienne des dix intelligences et entreprend une reconstitution de son modèle cosmologique. (shrink)

In "De anima" 3.5, Aristotle argues for the existence of a second intellect, the so-called "Agent Intellect." The logical structure of his argument turns on a distinction between different types of soul, rather than different faculties within a given soul; and the attributes he assigns to the second species make it clear that his concern here -- as at the climax of his other great works, such as the "Metaphysics," the "Nicomachean" and the "Eudemian Ethics" -- is the difference between (...) the human and the divine. If this is right, we needn't go on a wild goose chase trying to invent a role for the so-called Agent Intellect to play. God moves our intellects as he moves the heavenly spheres, "as a beloved": he constitutes the complete actualization towards which all of our intellectual striving is directed. Aristotle regards such final causation as an efficient cause, but not in a way that would make it part of what we would call the causal processes or mechanisms of human psychology. But, he would insist, it is essential for appreciating who we are and what our place is in the world. (shrink)

ABSTRACT Al-Ghazālī’s engagement with scepticism in the Deliverance from Error has received much attention in recent literature, often in the context of comparing him with Descartes. However, there is one curious text that has gone largely unnoticed by commentators. In his account of how he overcame scepticism vis-à-vis a divine light cast unto his heart, al-Ghazālī makes a cryptic claim that suggests that primary truths are inherent to the mind, and that said cognitive status of primary truths is related to (...) his overcoming of scepticism. Although this one text does not straightforwardly prove that al-Ghazālī is a nativist, I argue that there are other texts that plausibly reveal his nativism. As such, I argue that al-Ghazālī can be read as a nativist, and I reconstruct a way in which his nativism helps explain how he overcomes scepticism. In doing so, I defend the (standard) strong divine interventionist reading of al-Ghazālī’s response to scepticism, against Hadisi’s recent weak divine interventionist reading. (shrink)

The idea that nous comes from without, deriving from Aristotle’s Generation of Animals II.3, became a key element in late ancient and Medieval accounts of human rationality drawing on Aristotle’s De Anima. But two very different understandings of the concept were around (often occurring next to each other): either it was taken to refer to the human capacity for thought and its origin outside the natural ontogenetic process; or it was taken to stand for the most perfect act of thought, (...) existing separately as the supreme divinity, and becoming, hopefully, ours at the very climax of human development. This paper shows how these two influential conceptions derive from the work of the two greatest scholars of Aristotle’s school, Theophrastus and Alexander of Aphrodisias, respectively. More to the point: it shows that (i) there is an intriguing philosophical story to be told of how the notion developed from one understanding to the other, this being the core of a larger story of nous from without in Western thought; and that (ii) this story sheds new light on what was at stake in the early – genuinely Peripatetic – reception of Aristotle’s account of nous (as contrasted with later, heavily Platonized, interpretations).

A persistent tradition in metaphysics of mind insists that there is a substantial difference between mind and body. Avicenna’s numerous arguments, for a millennium, have encouraged the view that minds are essentially immaterial substances. In the first part, I redesign and offer five versions of such arguments and then I criticize them. First argument (indivisibility) would be vulnerable in terms of two counterexamples. Second argument (universals) confuses existence with location. Third argument (bodily tools) is less problematic than the first two, (...) though I will say a few words about why it may also not be convincing. Fourth argument (infinity) may not support substance dualism, because, I think, abundance is very different from infinity. Fifth argument (senescence) depends on empirically incorrect premises. Hence, it seems that no Avicennian argument can reasonably save substance dualism. (shrink)

In this paper, I join the so-called voluntarism debate on Descartes’s theory of will and judgment, arguing for an indirect doxastic voluntarism reading of Descartes, as opposed to a classic, or direct doxastic voluntarism. More specifically, I examine the question whether Descartes thinks the will can have a direct and full control over one’s suspension of judgment. Descartes was a doxastic voluntarist, maintaining that the will has some kind of control over one’s doxastic states, such as belief and doubt. According (...) to a long-held reading, the control that the will has over doxastic states in Descartes’s theory is direct; the doxastic states are affected by the mere act of will. This reading is called direct doxastic voluntarism (DDV), or direct voluntarism (DV) for short, and it states that we are capable of assenting, rejecting and suspending a judgment based only on our will to do so. Thus, these actions would be utterly and merely volitional. DV can be divided into two further positions, direct positive voluntarism (+DV) and direct negative voluntarism (-DV). Direct positive voluntarism deals with the act of forming judgments, maintaining that one can accept or deny a proposition wilfully and either merely believe or not believe something voluntarily. Direct negative voluntarism deals with the suspension of judgment, maintaining that it can likewise be accomplished by a simple act of will. However, I support an alternate account of Descartes’s voluntarism, which is called indirect doxastic voluntarism (IDV), or indirect voluntarism (IV) for short. By this account, the will is capable of affecting a doxastic state indirectly by making one concentrate on essential tasks for forming that state, such as gathering up and paying attention to strong reasons and evidence. IV is also possible to divide into indirect positive voluntarism (+IV) and indirect negative voluntarism (-IV). Per indirect positive voluntarism the will needs to pay attention to reasons for accepting or denying some proposition. Likewise, by indirect negative voluntarism, in order to suspend judgment the will needs to direct this attention to the reasons for doubt. By attending to these reasons, the will also comes face-to-face with its own freedom. This feeling of freedom can be described as affectivity of the reasons for belief (assent) and doubt (suspension). (shrink)

RésuméL'article étudie les rapports que la théorie thomasienne de la vision béatifique entretient avec la noétique qu'Averroès expose dans sonGrand CommentaireduDe anima. DuCommentaire des Sentences, où le jeune Thomas propose une transposition explicite de l'intellection philosophique des substances séparées dans l'ordre théologique chrétien, aux œuvres de la maturité, qui n'en font plus mention, on tâche de présenter la nature exacte des emprunts et d'apprécier leur justesse en s'interrogeant sur la cohérence conceptuelle du geste de l'Aquinate: Thomas pouvait-il suspendre sa conception (...) de la vision de Dieu par essence à un dispositif noétique originairement actif dans un système jugé erroné et contraire à la foi? Pouvait-on théologiquement accorder au rapport entre essence divine et intellect ce que, philosophiquement, on refusait à celui entre l'intellect séparé et le corps? Si Thomas et ses partisans, dans la querelle qui s'ouvrait, l'assurent, on indique nonobstant ce que l'emprunt paradoxal d'origine conserve de conceptuellement problématique au cœur du thomisme.

Avicenna introduces the primary propositions as the most fundamental principles of knowledge. However, as far as we are aware, Avicenna’s primaries have not yet been independently studied. Nor do Avicenna scholars agree on how to characterize them in the language of contemporary philosophy. It is well-known that the primaries are indemonstrable; nonetheless, it is not clear what the genealogy of the primaries is, how, epistemologically speaking, they can be distinguished from other principles, what their phenomenology is, what the cause of (...) the assent to them is, how to explain the relationship between the ‘innate [nature] of the intellect’ and the primaries and, finally, back to their indemonstrability, in what sense they are ‘indemonstrable’. We will try to fill this gap. As a corollary, we will explain why Gutas’s view [Gutas, Dimitri.... (shrink)

I offer a new interpretation of the passages where Aristotle maintains that intellectual activity employs φαντάσµατα (images). In theoretical understanding of mathematical and natural beings, we usually need to consciously employ appropriate φαντάσµατα in order to grasp explanatory connections. Aristotle does not, however, commit himself to thinking that images are required for exercising all theoretical understanding: understanding immaterial things, in particular, may not involve φαντάσµατα. Thus the connection that Aristotle makes between images and understanding does not rule out the possibility (...) that human intellectual activity could occur apart from the body. (shrink)

Abū Bakr al-Rāzī and al-Fārābī both adopt the classical ideal of a philosophical way of life in the sense that being a philosopher implies certain ethical guidelines to which the philosopher should adhere. In both cases, moreover, their ethical writings appear to reflect a certain tension with respect to what the ethical goal of the philosopher consists of. In this study, I will argue that this apparent tension is relieved when their ethics is understood as a progression in a double (...) sense. In the first sense, both authors adopt the Neoplatonic distinction between pre-philosophical and philosophical ethics. The second aspect of the progression takes place within the degree of virtue required of the philosopher, which for al-Rāzī and al-Fārābī proceeds in contrary directions. For al-Rāzī, the philosopher progresses from the moderately ascetic requirements ofSpiritual Medicineto the higher license present inPhilosophical Life, following the stages of the life of Socrates. In contrast, for al-Fārābī the progression follows roughly along the Neoplatonic grades of virtue from Aristotelian moderation, which inExhortation to the Way to Happinessis connected with character training in a pre-philosophical sense, towards purely contemplative existence.RésuméAbū Bakr al-Rāzī et al-Fārābī adoptent tous deux l'idéal classique d'un mode de vie philosophique, au sens où être philosophe implique de respecter une certaine éthique. Dans le cas de ces deux auteurs, leurs écrits sur l’éthique reflètent en outre une certaine tension vis-à-vis de ce qui constitue l'objectif éthique du philosophe. Dans cette étude, je montrerai que cette tension apparente s'estompe lorsque leur éthique est comprise comme une progression entendue en un double sens. Au premier sens, les deux auteurs adoptent la distinction néo-platonicienne entre éthique pré-philosophique et éthique philosophique. Le second aspect de la progression porte quant à lui sur le degré de vertu qui est attendu du philosophe – et qui, pour al-Rāzī et al-Fārābī, s'oriente dans des directions opposées. Pour al-Rāzī, le philosophe se hisse des exigences ascétiques modérées de laMédecine spirituellevers celles plus élevées de laVie philosophique, en suivant les pas de Socrate. Au contraire, pour al-Fārābī, la progression suit à peu près les stades néo-platoniciens de la vertu, partant de la modération aristotélicienne, liée, dans l’Exhortation au bonheur, à la formation du caractère au sens pré-philosophique, pour tendre vers une existence purement contemplative.
