Drawn from a wide range of writings and featuring state-of-the-art translations, _Basic Works_ offers convenient access to Thomas Aquinas' most important discussions of nature, being and essence, divine and human nature, and ethics and human action. The translations all capture Aquinas's sharp, transparent style and display terminological consistency. Many were originally published in the acclaimed translation-cum-commentary series _The Hackett Aquinas_, edited by Robert Pasnau and Jeffrey Hause. Others appear here for the first time: Eleonore Stump and Stephen Chanderbahn's translation of _On the Principles of Nature_, Peter King's translation of _On Being and Essence_, and Thomas Williams' translations of the treatises On Happiness and On Human Acts from the Summa theologiae. _Basic Works_ will enable students to immerse themselves in Aquinas's thought by offering his fundamental works without internal abridgements. It will also appeal to anyone in search of an up-to-date, one-volume collection containing Aquinas' essential philosophical contributions--from the Five Ways to the immortality of the soul, and from the nature of happiness to virtue theory, and on to natural law.

This book is a major contribution to the history of philosophy in the later medieval period (1250-1350). It focuses on cognitive theory, a subject of intense investigation during these years. In fact many of the issues that dominate philosophy of mind and epistemology today - intentionality, mental representation, scepticism, realism - were hotly debated in the later medieval period. The book offers a careful analysis of these debates, primarily through the work of Thomas Aquinas, John Olivi, and William Ockham. Each of these figures attempts to reconceptualise cognition along direct realist lines, criticising in the process the standard Aristotelian account. Though of primary interest to medieval philosophers, the book presupposes no background knowledge of the medieval period, and will therefore interest a broader community of philosophers concerned with the origins of contemporary cognitive theory.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 38.1 (2000) 27-40 [Access article in PDF] Sensible Qualities: The Case of Sound Robert Pasnau University of Colorado 1. Background The Aristotelian tradition distinguishes the familiar five external senses from the less familiar internal senses. Aristotle himself did not in fact use this terminology of 'external' and 'internal,' but the division became common in the work of Arab and Hebrew philosophers, and in the Latin West the distinction is taken for granted.1 I am going to put to one side the obscurities involved in the various internal senses of phantasia, imagination, memory, etc.; I will instead focus on the external senses. These five external senses—sight, hearing, smell, taste, touch—have their familiar counterparts in the external world: color, sound, odor, flavor, and the various tangible qualities. (The tangible qualities, unfortunately, resist being reduced to a single genus, and are typically listed as hot and cold, wet and dry, etc., where this etc. stands in for the complete list that one might or might not be able to give.2 ) These sensibilia (I will simply speak of sensibles) were known as the proper or special objects of the external senses.In addition to these proper objects, the senses were taken to have five common objects—size, shape, number, motion, rest—and also an unlimited variety of incidental objects, the per accidens sensibles—Coriscus, one's enemy, a horse race, etc. These per accidens sensibles are in a way the most interesting and important sense objects of all. They are interesting, first, inasmuch as one of the hardest and most interesting problems about perception is the problem of seeing as, which seems to be precisely the phenomenon at issue [End Page 27] here. They are important, also, inasmuch as genuine perception, as we now think of it, almost always involves the perception of something sensible per accidens. Our everyday sensory experiences revolve around the experience of seeing objects of certain kinds. We can of course step back and decide that what we are really seeing is colors and shapes. But that is not how we ordinarily see things.Despite their interest and importance, I want to put aside these per accidens sensibles, and focus instead on the common and proper sensibles, both of which Aristotle described as sensible per se (kath' hauta). In his classic statement on the objects of sensation, at De anima II 6, 418a7-25, Aristotle suggests that the grounds for distinguishing the per se from the per accidens are that the former sensibles are capable in their own right of making an impression on the senses. Color itself affects the external senses, and so does size. Coriscus, however, considered as Coriscus, does no such thing. He affects the senses only inasmuch as he is colored, perfumed, etc.3 To focus on the per se sensibles, then, is to focus on those things in the world that are suited to make impressions on the external senses.Why are some such sensibles proper, whereas others are common? The well-known rule of thumb here, reflected in how we refer to these sensibles, is that each proper sensible can be perceived by only one of the external senses. The common sensibles are those per se sensibles that fail this test. (Note that, of the common sensibles, only number, movement and rest are truly common to all five of the senses; shape and size are perceptible only by touch and sight.4 ) It is not clear, however, that this is the appropriate criterion for distinguishing the proper from the common sensibles. Albert the Great, for instance, argues that a proper sensible must meet three tests: (1) It is sensed by only one sense; (2) this sense is not capable of error with respect to it; and (3) the organ of this sense is naturally suited to be affected by it alone.5 The last of these tests is problematic, however, for at least two reasons. First, it is problematic for touch, given that the tangible qualities resist being reduced to a single genus. Second, more seriously...

Epistemology today centrally concerns the conceptual analysis of knowledge. Historically, however, this is a concept that philosophers have seldom been interested in analysing, particularly when it is construed as broadly as the English language would have it. Instead, the overriding focus of epistemologists over the centuries has been, first, to describe the epistemic ideal that human beings might hope to achieve, and then go on to chart the various ways in which we ordinarily fall off from that ideal. I discuss in detail two historical manifestations of idealized epistemology — Aristotle and Descartes — and then consider how this perspective might make a difference to the discipline today. In the end, an idealized epistemology points toward a normative, prescriptive rather than descriptive enterprise

A quick scan of the leading figures in western philosophy reveals that relatively few have made a name for themselves by defending intuitive, natural, and sensible positions. Aristotle is one, and perhaps Aquinas is another. Francisco Suarez, the sixteenth-century Spanish scholastic, would be a third. His invariable working procedure is to give copious consideration to the various ancient and medieval views, and then to find some sensible compromise position. But today Suarez can hardly claim to have a broad readership. Of his fifty-four Metaphysical Disputations, only nine have now been published in English, while his other works remain almost entirely untranslated. This clear and accurate new translation aims to show readers what they have been missing.

The third volume of The Cambridge Translations of Medieval Philosophical Texts will allow scholars and students access in English, to major texts that form the debate over mind and knowledge at the center of medieval philosophy. Beginning with thirteenth-century attempts to classify the soul's powers and to explain the mind's place within the soul, the volume proceeds systematically to consider the scope of human knowledge and the role of divine illumination, intentionality and mental representation, and attempts to identify the object of human knowledge in terms of concepts and propositions. The authors included are Henry of Ghent, Peter John Olivi, William Alnwick, Peter Aureol, William Ockham, William Crathorn, Robert Holcot, Adam Wodeham as well as two anonymous Parisian masters of arts. This volume will be an important resource for scholars and students of medieval philosophy, history, theology and literature

Thomas Aquinas gives us many reasons to think that conceptual thought is linguistic in nature. Most notably, he refers to a mental concept as a verbum or word. He further says that such concepts may be either simple or complex, and that complex concepts are formed out of simple ones, through composition or division. These complex concepts may either affirm or deny a predicate of a subject. All of these claims suggest that conceptual thought is somehow language-like. Moreover, Aquinas would have been led in this direction by several venerable traditions. Augustine, for instance, speaks of “the word that we speak in our heart, a word which is not Greek nor Latin nor part of any other language.” And Aristotle, at the beginning of his De interpretatione, says that spoken words are symbols or signs of mental concepts; later generations would take this claim to warrant a treatment of mental concepts as themselves a kind of language. But how exactly should we understand this apparent connection in Aquinas between thought and language?

Reply to NormoreCalvin Normore offers a very interesting big-picture thesis about the later medieval period, one with multiple components. First, he thinks the first quarters of the thirteenth century—the era of Albert the Great and Thomas Aquinas—are “gobsmacked” by the recovery of Aristotle’s work, and hence are “anomalous.” Second he thinks that, once the gobsmacking is over, the philosophers—beginning with Peter John Olivi and onward into the fourteenth century—return to “building upon the insights of the twelfth century”—that is, back to the era of Peter Abelard and others. Third, he thinks that this broader movement—what one gets if one sets aside the anomaly of Thomas Aquinas and his era—is characterized by a broader interest in the whole spectrum of ancient philosophical traditions, so that it is not just Aristotelian, but also Platonic and Stoic and Epicurean and much else. Fourth, this broadening movement sees its culmination in the seventeenth century, when the authority of

Beginning with a brief overview of Aquinas’ life and philosophical career, the authors introduce his overarching explanatory framework in order to provide the necessary background to his substantive theorizing in a wide range of areas: rational theology, metaphysics, philosophy of human nature, philosophy of mind, and ethical and political theory. Although not intended to provide a comprehensive evaluation of all aspects of Aquinas’ far-reaching writings, the volume does present a systematic introduction to the principal areas of his philosophy, attending no less to his methods and argumentative strategies than to his ultimate conclusions.

This is a major new study of Thomas Aquinas, the most influential philosopher of the Middle Ages. The book offers a clear and accessible guide to the central project of Aquinas' philosophy: the understanding of human nature. Robert Pasnau sets the philosophy in the context of ancient and modern thought, and argues for some groundbreaking proposals for understanding some of the most difficult areas of Aquinas' thought: the relationship of soul to body, the workings of sense and intellect, the will and the passions, and personal identity. Structured around a close reading of the treatise on human nature from the Summa theologiae and deeply informed by a wide knowledge of the history of philosophy and contemporary philosophy, this study will offer specialists a series of novel and provocative interpretations, while providing students with a reference commentary on one of Aquinas' core texts.

The secondary qualities are those qualities of objects that bear a certain relation to our sensory powers: roughly, they are those qualities that we can readily detect only through a certain distinctive phenomenal experience. Contrary to what is sometimes supposed, there is nothing about the world itself (independent of our minds) that determines the distinction between primary and secondary qualities. Instead, a theory of the secondary qualities must be grounded in facts about how we conceive of these qualities, and ultimately in facts about human perception.
