Avicennan Heritage The Avicennan Heritage earthly world reside as paradigms and from which they come to inform the sensible objects here on Earth. While this parallel has been noticed, it has also been claimed that as- Suhrawardī’s position differed from Avicenna’s in that the latter only accepted ten such immaterial intellects.7 In fact, Avicenna only conceded that there are ten immaterial intellects in the simplest cosmological model and that actually there are as many as required by one’s best astronomy. Where in fact the two thinkers differ is simply that as-Suhrawardī allows for there to be different immaterial substances of the same species only accidentally differing, a status that Avicenna reserves for immaterial human intellects alone, whereas all other immaterial Intelligences, he maintains, differ only according to species. None of my comments here are intended to suggest that Avicenna and as- Suhrawardī’s philosophical systems are the same. They are not. I merely want to emphasize as-Suhrawardī’s debt to Avicenna. In fact, Avicenna also owes a debt of sorts to as-Suhrawardī, for as-Suhrawardī, analogous to al-Ghazālī before him, recast many of Avicenna’s philosophical concepts and terminology into light metaphors and the mystical language of the Sufis. The result was that Avicenna’s philosophy could be incorporated into another aspect of Islamic spiritualism, namely, Sufi mysticism. In fact, the incorporation was so complete that certain twentieth-century scholars, such as Henri Corbin and his school, have argued that there was already a mystical element in Avicenna’s thought, albeit only explicitly presented in Avicenna’s work The Easterners, which is no longer extant in full.8 Whatever the case, there can be little doubt that Avicenna’s philosophy duly modified became ever more engrained in the philosophical framework of Muslim intellectual and spiritual thought. Avicenna likewise influenced the articulation of Jewish philosophical theology. While arguably the most important philosophical element in (p.249) Avicenna’s thought among later Muslim theologians was the distinction between essence and existence, a theme that runs throughout the Cure, among medieval Jewish theologians it appears to be Avicenna’s distinction between necessary existence and possible existence, which features prominently within the Salvation. The distinction was in fact taken over by no less a Jewish luminary than Moses ben Maimon, that is, Maimonides (ca. 1135–1204).9 So, for example, Maimonides’ third proof for the existence of God in the Guide for the Perplexed (II 1), which he erroneously attributes to Aristotle, is in fact a variation of Avicenna’s proof from possible and necessary existence. Moreover, in that same proof Maimonides, using the same distinction, rehearses Avicenna’s own arguments for the uniqueness of the divinity and for God’s incorporeality and simplicity. More important, and in certain respects more interesting, is Maimonides’ use of Avicenna’s distinction in articulating to what extent God can be said to have attributes beyond necessary existence (Guide for the Perplexed, I 52).

Subscriber: Xavier University; date: 15 May 2020 The Avicennan Heritage own position, one may recall, was that one could positively affirm that God was the Necessary Existent. Other than this single positive attribute, all other attributes, maintained Avicenna, have to be either negative, such as “incorporeal,” or relational, such as “(ontologically or temporally) prior to.” Maimonides’ own distinctive negative theology is best seen as a give and take between himself and Avicenna, agreeing that, with the exception of the attribute of being God (that is, the Necessary Existent), one should attribute negative attributes of the divinity, while disagreeing with Avicenna that one could attribute relational ones to the divinity. Thus, according to Maimonides, other than the attributes of action—which in fact flow from and are identical with God’s necessary existence—the divinity can be described only in negative terms. In contrast with Avicenna, however, Maimonides disagreed that relational attributes should be ascribed to God, and does so, ironically, for purely Avicennan reasons. For Avicenna, there is no single category “existence,” of which necessary existence and possible existence are its species; rather, both are categorically different, only sharing the name “existence” in an equivocal sense. Maimonides merely observed that in order for two things to stand in any meaningful relation they need to be at least categorically alike. To say of a lime, for instance, that the green (category of quality) is brighter, or sourer, or larger, or the like than its size (category of quantity) is just nonsense. The nonsense becomes even more exacerbated the further (p.250) removed the categories involved in the purported relation are; however, between necessary existence and possible existence not even existence is shared in common but is said equivocally. Thus, nothing of the created order, according to Maimonides, can stand in any relation to God such as to give rise to a relational attribute: Strictly speaking, for Maimonides, God is not before us, in us, with us, nor can any other relational attribute be assigned to God. In addition to drawing upon and adapting Avicenna’s necessary-possible existence distinction, Maimonides also took over, albeit in a qualified way, Avicenna’s account of prophecy. According to Avicenna, as noted, prophecy is not a supernatural phenomenon but a natural one, and as such is in need of a natural explanation. Within the framework of his psychology and particularly his accounts of insight (ḥads) and the internal sense faculty of the compositive imagination, Avicenna found just such an explanation. Avicenna’s prophet far from being individually chosen by God to be a vehicle of divine inspiration is merely a human who has insight to the superlative degree so as to be able fully and properly to grasp the inherent causal structure and order of the good found in the world. The prophet in turn can then imagine and explain this order in ways that capture the imagination of others. Maimonides, in fact, accepted this natural explanation of prophecy, while also finding a place in it for God (Guide for the Perplexed, I 32). For, according to Maimonides, God can prevent one whose psychological disposition is otherwise of such an excellent degree so as to qualify to be a prophet from in fact becoming a prophet.

Subscriber: Xavier University; date: 15 May 2020 The Avicennan Heritage my claim is not that Maimonides’ views are just those of Avicenna’s—they are not—rather, I merely want to emphasize the influence that Avicenna had on the formation of Maimonides’ own unique thought. Avicenna’s Heritage in the Christian World As with the Arabic East, so with the Latin West, Avicenna’s thought was a source of inspiration, particularly at the onset of the High Middle Ages. At that time there began a movement to translate Greek and Arabic scientific works into Latin that equaled the earlier Arabic translation movement in its breadth.10 At least one indication of the high regard in which early philosophers and translators in Europe, such as Dominicus Gundissalinus (p.251) (fl. 1150–1190) and his Jewish collaborator Ibn Daud (ca. 1110–1180), held Avicenna is seen in that his works were some of the first translated into Latin. Among the works of Avicenna translated were a fair bit of the Cure—including a little of the logic, about two-thirds of the general physics, and complete translations of other more specific works on natural philosophy, as well as the whole of the psychology and the metaphysics—the metaphysics of the Salvation, and, of course, The Canon.11 Avicenna’s Canon, with its handy compendium format, proved to be immensely popular in Europe, and continued to be a medical textbook at universities into the eighteenth century. It was his philosophy, however, that would have the most enduring effect, for it would influence (sometimes negatively, other times positively) some of the great Catholic theologians and philosophers of that time, such as Albert the Great, Thomas Aquinas, and Duns Scotus. So, for example, the foremost issue in scholastic natural philosophy involved the concept of motion, concerning which the question of in which Aristotelian category does it belong was of first most importance. Albert the Great (c. 1200– 1280) gave the question the form in which it was most frequently dealt throughout medieval Europe: Is motion a flowing form (forma fluens) or the form of a flow (fluxus formae)? While the language is Albert’s own, he found the statement of the problem, as he himself says, in the Physics of Avicenna’s Cure. Unfortunately, owing to a faulty Latin translation of a key passage—where Avicenna in fact articulated his theory of motion at an instant and then went on and developed his notion of a limit—and Albert’s own commentary on that passage, Avicenna’s own contribution to this issue was not appreciated at least in the Latin West.12 Still, it was Avicenna who raised the question that would stimulate so much discussion among Latin natural philosophers about the proper way to characterize motion. Moreover, the psychological work of Avicenna’s Cure, was second only to Aristotle’s in influencing Albert’s own psychological works.

  • The Univocity of Substance and the Formal Distinction of Attributes: the Role of Duns Scotus in Deleuze's Reading of Spinoza Nathan Widder
    parrhesia 33 · 2020 · 150-176 the univocity of substance and the formal distinction of attributes: the role of duns scotus in deleuze's reading of spinoza nathan widder This paper examines the role played by medieval theologian John Duns Scotus in Gilles Deleuze’s reading of Spinoza’s philosophy of expressive substance; more generally, it elaborates a crucial moment in the development of Deleuze’s philosophy of sense and difference. Deleuze contends that Spinoza adapts and extends Duns Scotus’s two most influential theses, the univocity of being and formal distinction, despite neither appearing explicitly in Spinoza’s writings. “It takes nothing away from Spinoza’s originality,” Deleuze declares, “to place him in a perspective that may already be found in Duns Scotus” (Deleuze, 1992, 49).1 Nevertheless, the historiographic evidence is clearly lacking, leaving Deleuze to admit that “it is hardly likely that” Spinoza had even read Duns Scotus (359n28). Indeed, the only support he musters for his speculation is Spinoza’s obvious in- terests in scholastic metaphysical and logical treatises, the “probable influence” of the Scotist-informed Franciscan priest Juan de Prado on his thought, and the fact that the problems Duns Scotus addresses need not be confined to Christian thought (359–360n28). The paucity of evidence supporting this “use and abuse” of history, however, does not necessarily defeat the thesis. Like other lineages Deleuze proposes, the one he traces from Duns Scotus to Spinoza, and subsequently to Nietzsche, turns not on establishing intentional references by one thinker to his predecessor, but instead on showing how the borrowings and adaptations asserted to create the connec- tion make sense of the way the second philosopher surmounts blockages he faces while responding to issues left unaddressed by the first.

  • The Distinction Between Reason and Intuitive Knowledge in Spinoza's
    The Distinction between Reason and Intuitive Knowledge in Spinoza’s Ethics Sanem Soyarslan Duke University While both intuitive knowledge (scientia intuitiva) and reason (ratio) are adequate ways of knowing for Spinoza, they are not equal. Intuitive knowledge has greater power over the passive affects than reason, and appreciating the nature of this superiority is crucial to understanding Spinoza‘s ethical theory. However, due to Spinoza‘s notoriously parsimonious treatment of the distinction between reason and intuitive knowledge in the Ethics, there has been little consensus in the literature regarding the nature of this distinction. Instead, several candidate interpretations have emerged, which can be broadly grouped under two categories: Form Interpretations (FI) and Content Interpretations (CI). According to the FI, which is held by scholars such as Yirmiyahu Yovel1 and Steven Nadler2, reason and intuitive knowledge are different only in terms of their form—that is, the process by which they are attained. Thus, the FI attributes the above epistemic asymmetry entirely to differences in the methods of cognition between intuitive knowledge and reason. By contrast, the CI, embraced by scholars such as Henry Allison3 and Edwin Curley4, holds that the two kinds of adequate knowledge differ not only in terms of their form, but also with regard to their content. More specifically, the CI maintains that reason involves the universal knowledge of the properties of things, whereas intuitive knowledge relates to the essence of things. I agree with the CI that reason and intuitive knowledge differ not only in form but also with respect to their content. Nevertheless, I believe there is an important gap in the CI: namely, although it maintains that adequate knowledge of the essences of things is limited to intuitive knowledge, it fails to flesh out precisely what these essences are taken to be.

  • Aristotle's Definition of Kinêsis: Physics III.1
    Aristotle’s Definition of Kinêsis: Physics III.1 Background In Physics I.7, Aristotle told us that change (coming to be) involved a subject (that persists through the change and a pair of contraries (the two termini of change). One might think that this provides him with a definition of change, since it seems to provide necessary and sufficient conditions. In the case of local change (movement), it would look like this: x moves iff x is at p1 at t1 and x is at p2 at t2 (where p1 ≠ p2, t1 ≠ t2). This would yield the so-called “at-at” theory of motion: to move is to be at one place at one time and at another place at another time. On this theory, moving is just a matter of being at different places at different times (and change in general is just a matter of being in different and incompatible states at different times). But although Aristotle thinks that this does indeed give us necessary and sufficient conditions for change, he does not think that it tells us what change is. This is obvious from the fact that in Physics III.1 he offers a definition of change (kinêsis) that looks very different from this. Why is this? Aristotle does not say. But presumably, the problem with the “at-at” theory is that it leaves out the crucial thing about change—namely, that it is a process or passage from one state to another, or from one place to another. That is, he thinks of change as a continuous not a discrete phenomenon.

  • Kripke on Modality
    KRIPKE ON MODALITY Saul Kripke’s published contributions to the theory of modality include both mathematical material (1959a, 1963a, 1963b, and more) and philosophical material (1971, henceforth N&I; 1980, henceforth N&N). Here the latter must be given primary emphasis, but the former will not be entirely neglected. APOSTERIORI NECESSITY Kripke’s overarching philosophical point is that the necessary is not to be confused with the apriori, but preliminary explanations are needed before his contribution can be specified more precisely. To begin with, the linguistics literature (Palmer 1986) distinguishes three flavors of modality: deontic, epistemic/evidential, and dynamic. The pertinent notions of necessity are the obligatory or what must be if obligations are fulfilled, the known or what must be given what is known, and the inevitable in the sense of what cannot fail and could not have failed to be, no matter what. This last is the only notion of necessity of interest in our present context. As Kripke emphasizes, this notion of the necessary and its correlative notion of the contingent are metaphysical concepts. They are as such at least conceptually distinct from the epistemological notions of the apriori and aposteriori and the semantical notions of the analytic and synthetic. Before Kripke this was never completely forgotten, but its importance was arguably grossly underestimated. Prior to Kripke’s work it was the near-unanimous opinion that the analytic is included in the apriori, which in turn is included in the necessary (Quine 1960: 59). It was the majority opinion that these inclusions reverse, making the three classifications coextensive; but there were dissenters, conscious of being in the minority (Kneale and Kneale 1962: 637-639).

  • Ontology, Analyticity and Meaning: the Quine-Carnap Dispute
    March 2008 March 2008 Ontology, Analyticity and Meaning: The Quine-Carnap Dispute by Scott Soames School of Philosophy University of Southern California In the middle of the twentieth century a dispute erupted between the chief architect of Logical Empiricism, Rudolf Carnap, and Logical Empiricism’s chief reformer, Willard van Orman Quine -- who was attempting to save what he took to be its main insights by recasting them in a more acceptable form. Though both eschewed metaphysics of the traditional apriori sort, and both were intent on making the investigation of science the center of philosophy, they disagreed about how to do so. Part of the disagreement involved the nature of ontological disputes. The central documents in the debate are: (i) Quine’s 1948 article, “On What There Is,” which tells us how to discern ontological commitments, what such commitments amount to, and how to evaluate them,1 (ii) Carnap’s 1950 article “Empiricism, Semantics, and Ontology,” which -- with the help an ambitious analytic/synthetic distinction -- attempts to reconcile his promiscuous commitment to a rich ontology of abstract objects with his puritanical devotion to empiricism by distinguishing scientifically tractable ontological issues from the unintelligible “psuedo-questions” of traditional ontology,2 (iii) Quine’s 1951 article “Two Dogmas of Empiricism” – which attacks Carnap’s analytic /synthetic distinction , and offers a holistic reconstruction of Logical Empiricism.3 Although these documents make up the core of the debate, they don’t exhaust it. For example, in 1951, Quine responded briefly in “On Carnap’s Views of Ontology.”4 In “Meaning and 1 Quine, “On What There Is,” Review of Metaphysics 2 (1948),: 21-38; reprinted in Quine, From a Logical Point of View, rev.

  • Ontology & Metaphysics
    On Doing Ontology without Metaphysics Achille C. Varzi Department of Philosophy, Columbia University, New York [Final version published in Philosophical Perspectives 25 (2011), 407–423] Introduction According to a certain, familiar way of dividing up the business of philosophy, made popular by Quine, ontology is concerned with the question of what entities exist (a task that is often identified with that of drafting a “complete inventory” of the universe) whereas metaphysics seeks to explain, of those entities, what they are (i.e., to specify the “ultimate nature” of the items included in the inventory).1 For instance, a thesis to the effect that there are such things as colors or virtues would strictly speaking belong to ontology, whereas it would pertain to metaphys- ics proper to establish whether such entities are Platonic forms, immanent univer- sals, tropes, moments, or what have you. Likewise, it would fall within the scope of ontology to determine whether, when we speak of Sherlock Holmes, of the natural numbers, or of Sebastian’s walks in Bologna, we are truly speaking of things that belong to the furniture of the universe, but it would be a further meta- physical task to say something precise in regard to the ultimate make-up of those things, if such there be—for instance, that Sherlock Holmes is a theoretical arti- fact, that numbers are abstract individuals, that walks are property exemplifica- tions, and so on. Of course, this view is everything but universal among philosophers. There are many other, different ways of understanding the terms ‘ontology’ and ‘meta- physics’, some of which can certainly claim a respectable pedigree.

  • Two Dogmas of Empiricism1a
    Two Dogmas of Empiricism1a Willard Van Orman Quine Originally published in The Philosophical Review 60 (1951): 20-43. Reprinted in W.V.O. Quine, From a Logical Point of View (Harvard University Press, 1953; second, revised, edition 1961), with the following alterations: "The version printed here diverges from the original in footnotes and in other minor respects: §§1 and 6 have been abridged where they encroach on the preceding essay ["On What There Is"], and §§3-4 have been expanded at points." Except for minor changes, additions and deletions are indicated in interspersed tables. I wish to thank Torstein Lindaas for bringing to my attention the need to distinguish more carefully the 1951 and the 1961 versions. Endnotes ending with an "a" are in the 1951 version; "b" in the 1961 version. (Andrew Chrucky, Feb. 15, 2000) Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact and truths which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. 1. BACKGROUND FOR ANALYTICITY Kant's cleavage between analytic and synthetic truths was foreshadowed in Hume's distinction between relations of ideas and matters of fact, and in Leibniz's distinction between truths of reason and truths of fact.

  • Notes on Avicenna's Concept of Thingness
    Arabic Sciences and Philosophy, vol. 10 (2000) pp. 181-221 Copyright © 2000 Cambridge University Press NOTES ON AVICENNA’S CONCEPT OF THINGNESS (SˇAY’IYYA)* ROBERT WISNOVSKY In an article published in 1984, Jean Jolivet suggested that the origins of Avicenna’s distinction between essence and existence lay not in ancient Greek philosophy, as has generally been sup- posed, but in early Islamic dogmatic theology (kal®m), and specifically in the ninth- and tenth-century-CE debates between Muslim dogmatists (mutakallim‚n) over how the terms “thing” (·ay’) and “existent” (maw™‚d) relate to each other.1 The pre- sent article provides evidence that gives qualified support to Jolivet’s hypothesis. I argue that Jolivet is correct in highlight- ing the kal®m background to Avicenna’s essence-existence dis- tinction, but that an important and previously overlooked testing-ground for that distinction, Avicenna’s analysis of the relation between efficient and final causes, arose from an entirely Aristotelian problematic. This article has three parts. Part 1 is an introduction to the problem. I shall survey early kal®m discussions of things and existents and present evidence supporting Jolivet’s hypothesis that these kal®m discussions were the backdrop against which Avicenna made his distinction between essence (m®hiyya, liter- ally “whatness,” and often Latinized as “quiddity”) and exis- tence (wu™‚d).2 While it is easy to imagine a progression from * Earlier versions of this article were presented at King’s College London, Harvard University and Hunter College, New York.

  • Are Potency and Actuality Compatible in Aristotle?
    Are Potency and Actuality Compatible in Aristotle? Abstract: The belief that Aristotle opposes potency (dunamis) to actuality (energeia or entelecheia) has gone untested. This essay defines and distinguishes forms of the Opposition Hypothesis—the Actualization, Privation, and Modal—examining the texts and arguments adduced to support them. Using Aristotle’s own account of opposition, the texts appear instead to show that potency and actuality are compatible, while arguments for their opposition produce intractable problems. Notably, Aristotle’s refutation of the Megarian Identity Hypothesis applies with equal or greater force to the Opposition Hypothesis. For Aristotle, then, potency and actuality are compatible. Keywords: Aristotle; Potency; Actuality; Metaphysics; Physics; Ancient Philosophy Aristotle’s contribution to ontology left at least two landmarks: the first, through working out the account of a categorical sense of being and its assertoric structure, and the second, through working out the philosophical import of potency (dunamis) and articulating its activity (energeia) and fulfillment (entelecheia) as a distinct, all‐pervasive sense of being. The latter contribution will, however, remain unclear to us to the extent that the relationship between these terms is unclear or unthought. Aristotle says explicitly that potency (dunamis) and being‐at‐work (energeia) are not simply the same: “it is clear that potency and being‐at‐work are different (for these assertions [of the Megarians] make potency and being‐at‐work the same [tauto], for which reason it is no small thing they are seeking to abolish)” (Met. IX.3 1047a20).1 Yet this claim comes only three chapters after the claim that they are in fact one and the same: “the boundary [eschatē: limit, extremity, definition] of material and the form are the same and one [tauto kai en], one potentially, the other actively… and what is in potency and what is in activity are in a way one [en pōs estin]” (Met.

  • Immanent Causation in Spinoza and Scholasticism
    Immanent Causation in Spinoza and Scholasticism by Stephen John Zylstra A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Philosophy University of Toronto © Copyright by Stephen John Zylstra 2018 ABSTRACT Immanent Causation in Spinoza and Scholasticism Stephen John Zylstra Doctor of Philosophy Department of Philosophy University of Toronto 2018 Spinoza is well-known for his claim that God is the only substance that exists, and that everything else is a mere “mode” of that substance. At the same time, Spinoza maintains that all things depend causally on God for their being. But if all of reality is in some sense identical with God, in what manner can God be its cause? Spinoza’s answer is found in his claim that “God is the immanent, and not the transeunt, cause of all things.” In this thesis, I investigate the scholastic roots of this distinction and its implications for understanding the fundamental features of Spinoza’s monistic ontology. The scholastics commonly distinguish between two kinds of activities, one which “remains” in the subject doing it and the other which “passes” outside. Those classified as immanent were primarily mental operations like thinking and willing. The first part of this thesis examines how the scholastics disagree over whether this kind of activity ought to be construed as a kind of production; the nature of its relation to its subject; and ii whether it is produced by means of ‘emanation’. The concept of an immanent cause emerges within this context. In the second part of this thesis, I bring this research to bear on our understanding of Spinoza’s metaphysics.
