Anthony J. Lisska presents a new analysis of Thomas Aquinas's theory of perception. While much work has been undertaken on Aquinas's texts, little has been devoted principally to his theory of perception and less still on a discussion of inner sense. The thesis of intentionality serves as the philosophical backdrop of this analysis while incorporating insights from Brentano and from recent scholarship. The principal thrust is on the importance of inner sense, a much-overlooked area of Aquinas's philosophy of mind, with (...) special reference to the vis cogitativa. Approaching the texts of Aquinas from contemporary analytic philosophy, Lisska suggests a modest 'innate' or 'structured' interpretation for the role of this inner sense faculty. He argues that were it not for the vis cogitativa, Aquinas would be unable to account for an awareness of the principal ontological category in his metaphysics. (shrink)

Kant's critical philosophy promises to overturn both Empiricism and Rationalism by arguing for the necessity of a passive faculty, sensibility, and an active faculty, understanding, in order for cognition to obtain. Kant argues in favor of sense impression found in standard empirical philosophies while advocating conceptual necessities like those found in rational philosophies. It is only in the synthesis of these two elements that cognition and knowledge claims are possible. However, by affirming such a dualism, Kant has created yet another (...) problem familiar to the history of philosophy, one of faculty interaction. By affirming two separate and exclusive capacities necessary for cognition, Kant has bridged the gap between the two philosophical traditions, but created a gap that must be overcome in order to affirm his positive programmatic. Kant himself realizes the difficulty his new philosophy faces when he claims the two sources of knowledge must have a "common, but unknown root." To complete Kant's program one must ask: "What bridges the gap between sensible intuition and conceptual understanding?" In my dissertation, I turn to Kant's philosophy and find the answer to this question in the productive imagination. In order to evaluate the viability of this answer, I problematize the imagination as it has been found in the history of Western philosophy. By tracing the historical use of the imagination in archetypal figures from both empiricist and rationalist traditions, one finds a development of imagination that culminates in the fundamental formulation found in Kant's Critique of Pure Reason. In his critical philosophy, Kant synthesizes the imagination and the use of imagination found in both traditions, thus demonstrating its role in both sensation and understanding. By employing the imagination at both sensorial and conceptual levels, Kant has found, I argue, the liaison that overcomes the dualism established by his requirements for knowledge, as well as the common root for both.

This paper examines Pomponazzi's arguments against Averroes in his De Immortalitate Animae, focusing on the question whether thought is possible without a body. The first part of the paper will sketch the history of the problem, namely the interpretation of Aristotle's remarks about the intellect in De Anima 3.4-5, touching on Alexander, Themistius, and Averroes. The second part will focus on Pomponazzi's response to Averroes, including his use of arguments by Aquinas. It will conclude by suggesting that Pomponazzi's discussion stands (...) as the first properly modern account of Aristotle's psychology. (shrink)

This project is guided and motivated by the question concerning the nature of the phantasm as that which mediates between sensation and intellection in John Duns Scotus' account of cognition. Scotus embraces Aristotle's claim that the intellect cannot think without the phantasm. The phantasm is in a corporeal organ, yet the immaterial intellect must act with it to produce an intelligible species. In this project I examine the critical elements of Scotus' cognitive theory in order to understand the nature of (...) the phantasm. In the first chapter I discuss key elements of Aristotle's metaphysics and give a close, textual reading of De Anima guided by his claim that the relationship of the body and soul is highly specific. I then focus on his claim in De Anima 2.12 that sensation involves the reception of the sensible form without the matter. In the second chapter, I discuss Scotus' key theological notions that guide and inform his cognitive project. The beatific vision requires the presence of the divine essence in its own existence to the intellect. As the highest cognitive experience, the beatific vision is definitive of all cognitive experience making the presence of the object to the cognitive faculty of central importance. The discussion of the incarnation shows that the world is sacralized and thus, is a worthy object of cognitive attention in itself. In the third chapter, I discuss Scotus' understanding of the body-soul relationship focusing on his notion of person to both secure the unity of the human being and to ground the mediation between sensation and intellection. In the fourth chapter, I first discuss Aquinas' claim that sensation requires a spiritual change. While Scotus's account is in many respects the same as Aquinas', Scotus does not maintain that sensation is primarily passive and is thus, able to account for cognitive attention by way of his understanding of the unity of the sense organ, immanent actions, and sensation as intuitive cognition. What emerges in this discussion is Scotus' particular understanding of an intentio by which the nature of the phantasm can be understood. (shrink)

Este artículo presenta una traducción al español de la teoría de Alberto Magno sobre la imaginación y la fantasía. El texto correspondiente se deriva de su comentario al De Anima libro III tratado 1 capítulos 1-3. De acuerdo con Alberto, la imaginación consigue la segunda de cuatro fases de la abstracción al abstraer desde la presencia del objeto percibido, mientras que la función propia de la fantasía consiste en entender el objeto sensible bajo sus aspectos intencionales.
