This book investigates Aristotle’s views on abstraction and explores how he uses it. In this work, the author follows Aristotle in focusing on the scientific detail first and then approaches the metaphysical claims, and so creates a reconstructed theory that explains many puzzles of Aristotle’s thought. Understanding the details of his theory of relations and abstraction further illuminates his theory of universals. Some of the features of Aristotle’s theory of abstraction developed in this book include: abstraction is a relation; perception (...) and knowledge are types of abstraction; the objects generated by abstractions are relata which can serve as subjects in their own right, whereupon they can appear as items in other categories. The author goes on to look at how Aristotle distinguishes the concrete from the abstract paronym, how induction is a type of abstraction which typically moves from the perceived individuals to universals and how Aristotle’s metaphysical vocabulary is "relational.’ Beyond those features, this work also looks at how of universals, accidents, forms, causes and potentialities have being only as abstract aspects of individual substances. An individual substance is identical to its essence; the essence has universal features but is the singularity making the individual substance what it is. These theories are expounded within this book. One main attraction in working out the details of Aristotle’s views on abstraction lies in understanding his metaphysics of universals as abstract objects. This work reclaims past ground as the main philosophical tradition of abstraction has been ignored in recent times. It gives a modern version of the medieval doctrine of the threefold distinction of essence, made famous by the Islamic philosopher, Avicenna. (shrink)

Both through his own work and that of his students, Franz Clemens Brentano had an often underappreciated influence on the course of 20 th - and 21 st -century philosophy. _The Routledge Handbook of Franz Brentano and the Brentano School_ offers full coverage of Brentano’s philosophy and his influence. It contains 38 brand-new essays from an international team of experts that offer a comprehensive view of Brentano’s central research areas—philosophy of mind, metaphysics, and value theory—as well as of the principal (...) figures shaped by Brentano’s school of thought. A General Introduction serves as an overview of Brentano and the contents of the volume and three separate bibliographies point students and researchers on to further avenues of inquiry. Systematic and detailed, _The Routledge Handbook of Franz Brentano and the Brentano School_ provides readers with a valuable reference to Brentano’s work, and to his lasting importance in the history of philosophy and in contemporary debates.

Este artículo rastrea la presencia del realismo, el empirismo y el sinequismo en las teorías de la cognición de Aristóteles y de Charles S. Peirce. Los dos primeros términos se relacionan comúnmente con ambos autores, pero aquí se quiere precisar en detalle qué semejanzas y diferencias hay entre el realismo y el empirismo de estos dos filósofos. De otro lado, el sinequismo se relaciona solo con Peirce, mientras que a Aristóteles se le ubica precisamente como opositor a cualquier idea de (...) continuidad e infinito. Lo que se quiere mostrar aquí es que, al menos en el ámbito de la cognición, Aristóteles es también un sinequista. Otro punto importante del artículo es que intenta criticar y corregir la interpretación que hace Peirce del empirismo de Aristóteles al intentar erróneamente de afirmar que el filósofo griego es un intuicionista.

The Middle Included is a systematic exploration of the meanings of logos throughout Aristotle’s work. It claims that the basic meaning is “gathering,” a relation that holds its terms together without isolating them or collapsing one to the other. This meaning also applies to logos in the sense of human language. Aristotle describes how some animals are capable of understanding non-firsthand experience without being able to relay it, while others relay it without understanding. Aygün argues that what distinguishes human language, (...) for Aristotle, is its ability to both understand and relay firsthand and non-firsthand experiences. This ability is key to understanding the human condition: science, history, news media, propaganda, gossip, utopian fiction, and sophistry, as well as philosophy. Ömer Aygün finds Aristotle’s name for this peculiar but crucial human ability of “gathering” both experiences is logos, and this leads to a claim about the specificity of human rationality and language.

Understanding the “intentionality” of mental phenomena is widely regarded as a key problem in philosophy of mind. Franz Brentano (along with his students, especially Edmund Husserl) is widely credited with bringing intentionality to philosophers’ attention. In early treatment by the Brentano school, intentionality is at least nominally understood as executed, brought about, or achieved in mental acts. And in the early 20th century, historians of psychology regarded this “act conception” of intentionality as integral for understanding the phenomenon. Yet the secondary (...) literature on Brentano and Husserl provides no clarification of mental acts as acts, and in contemporary philosophy, we have no workable account of what it could mean for intentionality to arise through mental acts. The main difficulty is that “act” is widely regarded as synonymous with “volitional personal action.” Since we as human agents certainly do not willfully bring about much of our own mental life, and since (on the standard analyses) all such volition presupposes intentionality, it is a mystery to work out what the act conception of intentionality could have amounted to. This dissertation is a systematic explication of the historical act concept of intentionality. Part I examines Brentano. I show that his early work on Aristotle’s psychology provides resources to think coherently about many mental phenomena as acts, even if they are not personal actions. However, I also show that Brentano’s mature psychology is not Aristotelian, at least insofar as it does not (and cannot) deploy an Aristotelian conception of mental acts. Part II examines Husserl. I show that Husserl’s mature transcendental phenomenology works with a robust and many-layered conception of mental acts, and that understanding intentionality as active is essential to the phenomenological viewpoint. Moreover, I argue that Husserl’s conception of mental acts can be viewed as a transcendentalized, neo-Aristotelian view. The results will be of special interest to historians of philosophy, but also have a much broader significance. Husserl’s view provides us with a model of what can be called an “internalist enactivism.” Any view along these lines represents a novel position that has not been articulated (or even considered) in contemporary debates.

In Aristotle’s De anima 3.5, the relation between intellect and thought, and between thought and object, is not accessible to discursive or conscious thought; an understanding of the relation requires nous, intuitive or “unconscious” thought. The “active” intellect is accessible to discursive reason only sporadically. “Mind does not think intermittently” : mind is always thinking, consciously and unconsciously. Alexander of Aphrodisias saw the active intellect as transcendent in relation to the material intellect. The thought which is an object of thought (...) is immaterial, or unconscious. In his De intellectu, there must be something at work in thought for which “what it is to be intellect does not lie in its being thought by us,” that is, unconscious. In the De anima of Themistius, mind as passive, in its material potentiality, is destructible and subject to time, but mind as active is free from its material conditions. Discursive thinking is equivalent to thinking in time; time is not present in the same way in unconscious thought or dreams.In the De intellectu of Alfarabi, when intellect “thinks that existent thing which is an intellect in actuality, it does not think an existing thing outside of itself but it only thinks itself,” in unconscious thought. Intellect as the object of its own thought is inaccessible to conscious reason. Intellect ascends from material to agent intellect and we ascend “from that which is best known to us to that which is unknown,” in the unconscious. The knowledge of things which are most accessible to intellect is the lowest form of knowledge; in order to develop, intellect must come to grasp the knowledge which is least accessible and most unconscious. In the Liber Naturalis of Avicenna, intellect is seen as a palimpsest of traces of forms and thoughts of varying clarity in relation to cognition, conscious thought. Unconscious thought is seen as the intelligible in cognition in the Aristotelian model, only accessible to conscious thought or actual intellect to varying degrees. The active intellect of Averroes can be seen as a form of unconscious thought. In his Long Commentary on the De anima, the activity of the active intellect makes images intelligible in unconscious thought, according to Franz Brentano. (shrink)
