This volume, including sixteen contributions, analyses ancient and medieval theories of intentionality in various contexts: perception, imagination, and intellectual thinking. It sheds new light on classical theories and examines neglected sources, both Greek and Latin.

Averroes asserts in his Long Commentary on the De Anima and in his Long Commentary on the Metaphysics that principles of the science of metaphysics are established in the science of psychology. In psychology, human intellectual understanding is found to require the separate agent intellect for the coming to be of knowledge. The analysis of human psychology establishes that intellect must exist and must be separate from the human being in existence. Moreover there exists potency in those things called intellect, (...) thanks to the argument for the existence of the material intellect. (shrink)

Cognition is a basic introductory text for college courses in the philosophy of knowledge. Joseph Owens, C.Ss.R., here expands the narrowly metaphysical treatment of knowledge given in his earlier book, An Elementary Christian Metaphysics, into a full-fledged epistemology. This text utilizes the traditions of Aristotle and Thomas Aquinas to reacquaint students of philosophy with a number of insights basic for a philosophic understanding of knowledge. These insights into the nature of abstraction, truth, the ground of certitude, and other major concerns (...) of epistemology will help students clarify the approaches of contemporary philosophies.

This paper suggests several summa genera for the various meanings of intentio in Aquinas and briefly outlines the genera of cognitive intentiones. It presents the referential and existential nature of intentions of harm or usefulness as distinguished from external sensory or imaginary forms in light of Avicenna’s threefold sensory abstraction. The paper offers a terminological clarification regarding the quasi-immaterial existential status of intentions. Internal sensory intentions account for a way in which one perceives something, as is best seen in light (...) of the distinction between formal and material objects. Against the imagist account of intentions that denies the memorative power an immanent object, it shows that the memorative’s proper and immediate object is the intention of the past, while its extrinsic mediate object is the imaginary phantasm.

In contemporary literature, one can find much information concerning Thomas Aquinas's doctrine of intelligible species. However, none of the literature takes into account how and why Aquinas developed his doctrine of intelligible species. Often, it is purported that Aquinas is just following Aristotle. However, this is not the case. There are aporiae in the Aristotelian corpus, and those who followed Aristotle tried to resolve the intellection and hylomorphism aporia, an aporia that arose as a result of denying Platonic forms and (...) affirming hylomorphism. Among those who attempted to resolve this aporia were Avicenna and Averroes from whom Aquinas drew and developed his doctrine of intelligible species. Avicenna's and Averroes' influence on Aquinas's doctrine of intelligible species is the focus of this dissertation. In addition, Aquinas's hylomorphic doctrines and natural and supernatural psychologies are explicated, and the influence of Avicenna and Averroes on Aquinas's psychologies is highlighted. Finally, the arguments posed by contemporary scholars as to whether Aquinas is a direct realist or a representationalist are reviewed in light of the Arabic contributions and Aquinas's synthesis.
