The relation-theory of mental acts proposes that a mental act is a kind of relative entity founded upon the mind and directed at the object of perception or thought. While most medieval philosophers recognized that there is something importantly relational about thought, they nevertheless rejected the view that mental acts are wholly relations. Rather, the dominant view was that a mental act is either in whole or part an Aristotelian quality added to the mind upon which such a relation to (...) the object can be founded. In this paper, I examine Durand of St.-Pourçain's defense of the relation-theory of mental acts against two objections raised against it: the first from John Duns Scotus, among others, and the second from an anonymous Thomist and Adam Wodeham. -/- .

Plenitude, roughly, the thesis that for any non-empty region of spacetime there is a material object that is exactly located at that region, is often thought to be part and parcel of the standard Lewisian package in the metaphysics of persistence. While the wedding of plentitude and Lewisian four-dimensionalism is a natural one indeed, there are a hand-full of dissenters who argue against the notion that Lewisian four-dimensionalism has exclusive rights to plentitude. These ‘promiscuous’ three-dimensionalists argue that a temporalized version (...) of plenitude is entirely compatible with a three-dimensional ontology of enduring entities. While few would deny the coherence of such a position, and much work has been done by its proponents to appease critics, there has been surprisingly little by way of exploring the various forms such an ontology might take as well as the potential advantages of one plenitudinous three-dimensional ontology over another. Here I develop a novel form of plenitudinous three-dimensionalism, what John Hawthorne (Metaphysical essays, 2006a, b) has called “Neo-Aristotelian Plenitude,” and argue that if one is inclined to endorse an abundant three-dimensional ontology, one is wise to opt for a plenitude of accidental unities.

It is generally assumed that Descartes invokes “objective being in the intellect” in order to explain or describe an idea’s status as being “of something.” I argue that this assumption is mistaken. As emerges in his discussion of “materially false ideas” in the Fourth Replies, Descartes recognizes two senses of ‘idea of’. One, a theoretical sense, is itself introduced in terms of objective being. Hence Descartes can’t be introducing objective being to explain or describe “ofness” understood in this sense. Descartes (...) also appeals to a pretheoretical sense of ‘idea of’. I will argue that the notion of objective being can’t serve to explain or describe this “ofness” either. I conclude by proposing an alternative explanation of the role of objective being, according to which Descartes introduces this notion to explain the mind’s ability to attain clear and distinct ideas.

In line with earlier works, this article argues for a “continuist” interpretation of Brentano’s conception of intentionality. It maintains that Brentano’s conception of intentionality rests on a complex set of notions, which are reduced to a minimal core or applied more fully depending on the complexity of the mental phenomenon under consideration and perspective from which it is analyzed. The article positions this conceptual structure in relation to theories of objects developed within the framework of late- and Neo-Scholastic philosophy where, (...) since the psychic act can relate to its object in different ways, the different types and roles of objects must be distinguished. This theory of objects enables Brentano to reinterpret Aristoteles’s idea of the intentionality of mental phenomena in light of the commentaries and interpretations of Thomas Aquinas while also giving space to other medieval texts.

Thomas Aquinas and Hervaeus Natalis share a correlational theory of intentionality. When I cognize a thing, I am in a real relation with the thing cognized and at the same time the thing is in a relation of reason with me. Hervaeus coins the term “intentionality” to designate precisely this relation of reason. First and second intentionality express two stages of this relation. First intentionality refers to the relation that a thing has to the mind, while second intentionality indicates the (...) relation that a thing qua cognized has to the mind. Thus, first intentionality involves direct cognition, while second intentionality reflexive cognition. This theory of intentionality has two purposes: first, to de-psychologize the cognitive process and second, to allow the application of Aristotle’s table of categories to the sphere of the mental. Through his detailed analysis of the relation of intentionality, Hervaeus clarifies some of Thomas’s obscurer points, but at the same time he has to solve a delicate problem of circularity entailed by the notion of intentionality as a relation of reason.

ABSTRACTThomas Aquinas argues that the agent intellect's function is to abstract an intelligible species from a phantasm. However, insofar as he claims that the intelligible species is not present in the phantasm, it is unclear how the agent intellect accomplishes this task. In this paper I explore two models of abstraction – the extraction model and the production model – suggesting that each fails to capture Aquinas’ understanding of abstraction. I then offer my own interpretation of the function of the (...) agent intellect – the illumination model – by employing Aquinas’ comparison of the agent intellect to light. I argue that the agent intellect neither extracts nor produces an intelligible species, but rather makes the nature that is already present in the object intelligible by actualizing its passive power of intelligibility. This involves the co-actualization of partner powers in the intellect and in the intelligible object, and ultimately makes it possible to cognize a particular, material object in a universal way.

The purpose of this entry is to provide a systematic introduction to medieval views about the nature and ontological status of relations. Given the current state of our knowledge of medieval philosophy, especially with regard to relations, it is not possible to discuss all the nuances of even the best known medieval philosophers' views. In what follows, therefore, we shall restrict our aim to identifying and describing (a) the main types of position that were developed during the Middle Ages, and (...) (b) the most important considerations that shaped their development. We shall have occasion along the way, however, to examine in detail certain aspects of the views of important representatives of all the main medieval positions, including Peter Abelard (1079 1142), Gilbert of Poitiers (1085 1154), Albert the Great, (1200 1280), Thomas Aquinas (1225 1274), John Duns Scotus (1265 1308), Henry Harclay (1270 1317), Peter Auriol (1280 1322), and William Ockham (1285 1347).

Berkeley’s capacity to conceive of mind-independent bodies was corrupted by his theory of representation. He thought that representation of things outside the mind depended on resemblance. Since ideas can resemble nothing than ideas, and all ideas are mind dependent, he concluded that we couldn’t form ideas of mind-independent bodies. More generally, he thought that we had no inner resembling proxies for mind-independent bodies, and so we couldn’t even form a notion of such things. Because conception is a suggestible faculty, Berkeley’s (...) arguments actually made it the case that he himself couldn’t conceive of mind-independent bodies. (shrink)

The idea that the Leviathan frontispiece offers a visual summary of the contents of the work is widespread. However, the analysis of the frontispiece often under-explores Leviathan's text or leaves certain iconographic elements aside. In discussions of the Scholastics ‘Dilemma’ emblem, for instance, the image is commonly reduced to a representation of ‘logic’ or ‘scholasticism’, leaving aside the intricate interrelationship between the objects present in the image and their connection with the content of the book. This paper argues that this (...) image helps understanding Hobbes’ critique of Scholastic doctrines and their political effects in Leviathan. For Hobbes, these supposedly pure philosophical concepts either in logic (trident of the ‘Syllogism’) or metaphysics (‘Real/Intentional’ bident) hide a central part of Scholastic thought: a ‘seditious’ political conception claiming that the Pope has an indirect right to temporal power in affairs concerning spiritual matters theory (‘Spiritual/Temporal’ and ‘Direct/Indirect’ bidents). The Scholastic model made the common people believe that the Pope would have at least as much authority as the Sovereign. When faced with the choice between obeying either the Pope or their Civil Sovereign the subjects would find themselves in a dangerous ‘Dilemma’. (shrink)

It is widely thought that Augustine thinks perception is, in some distinctive sense, an active process and that he takes conscious awareness to be constitutive of perception. I argue that conscious awareness is not straightforwardly constitutive of perception and that Augustine is best understood as an indirect realist. I then clarify Augustine’s views concerning the nature and role of diachronically unified conscious awareness and mental representation in perception, the nature of the soul’s intentio, and the precise sense in which perception (...) is an active process.

Contemporary philosophers of mind tend to accept either some version of dualism or physicalism when considering the mind–body problem. Likewise, recent philosophers of religion typically assume that we must work within these two categories when considering problems related to the possibility of bodily resurrection. Recently, some philosophers have reintroduced the Thomistic version of hylomorphism. In this article, we will consider the distinctive doctrines of Thomistic hylomorphism and how they can be used to address concerns about both the mind–body problem and (...) the possibility of resurrection. We will see that hylomorphism allows for a novel version of emergent property dualism that is both metaphysically plausible and allows us to recognize the irreducibility of mental states and the possibility of resurrection without ignoring the fact of human embodiment. We will also discuss the currently lively debate among Thomistic hylomorphists who advocate opposed corruptionist and survivalist versions of the afterlife. (shrink)

We humans and other animals continuously construct and main- tain our grasp of the world by using astonishingly small snippets of sensory information. Recent studies in nonlinear brain dynamics have shown how this occurs: brains imagine possible futures and seek and use sensory stimulation to select among them as guides for chosen actions. On the one hand the scientific explanation of the dynamics is inaccessible to most of us. On the other hand the philosophical foundation from which the sciences grew (...) is accessible through the work of one of its originators, Thomas Aquinas. The core concept of intention in Aquinas is the inviolable unity of mind, brain and body. All that we know we have constructed within ourselves from the unintelligible fragments of energy impacting our senses as we move our bodies through the world. This process of intention is transi- tive in the outward thrust of the body in search of desired future states; it is intransitive in the dynamic construction of predictions of the states in the sensory cortices by which we recognize suc- cess or failure in achievement. The process is phenomenologically experienced in the action-perception cycle. Enactment is through the serial creation of neurodynamic activity patterns in brains, by which the self of mind-brain-body comes to know the world first by shaping the self to an approximation of the sought-for input, and then by assimilating those shapes into knowledge and meaning. This conception of the self as closed, autonomous, and self- organizing, devised over 700 years ago and shelved by Descartes, Leibniz and Spinoza 300 years ago, is now re-emerging in philos- ophy and re-establishes the meaning of intention in its original sense. The core Aquinian concept of the unity of brain, body and soul/mind, which had been abandoned by mechanists and replaced by Brentano and Husserl using the duality inherent in representa- tionalism, has been revived by Heidegger and Merleau-Ponty, but in phenomenological terms that are opaque to neurscientists. In my experience there is no extant philosophical system than that of Aquinas that better fits with the new _ndings in nonlinear brain dynamics. Therefore, a detailed reading and transcription of basic terms is warranted, comparing in both directions the significance of key words across 700 years from medieval metaphysics to 21st century brain dynamics.
