According to a long interpretative tradition, Aristotle holds that the formal cause is the ultimate object of induction when investigating perceptible substances. For, the job of induction is to find the essential nature common to a set of individuals, and that nature is captured solely by their shared formal cause. Against this view, I argue that Aristotle understands perceptible individuals as irreducibly composite objects whose nature is constituted by both their formal and their material cause. As a result, when investigating (...) perceptible objects, the job of induction is to discover their composite, formal and material nature. The process by which universal claims about this composite nature are justified, I argue, is similar to what we now know as mathematical induction. In particular, such claims are grounded in a non-enumerative, but replicable process in which things are resolved into their simplest components. As a result, the observation of past uniformities has, at most, a heuristic function in scientific inquiry. (shrink)

This chapter considers Aristotle's requirements for perceptible objects qua movable, changeable, and perceptible, namely that they must be extended in three dimensions, movable in space, and capable of physical contact with other extended bodies.

Although Aristotle's contribution to biology has long been recognized, there are many philosophers and historians of science who still hold that he was the great delayer of natural science, calling him the man who held up the Scientific Revolution by two thousand years. They argue that Aristotle never considered the nature of matter as such or the changes that perceptible objects undergo simply as physical objects; he only thought about the many different, specific natures found in perceptible objects. Against this (...) view, this book argues that Aristotle offers a systematic account of matter, motion, and the basic causal powers found in all physical objects. It argues that Aristotle not only sees all perceptible objects as sharing certain basic physical properties, but he also holds that perceptible objects have these physical properties because they are ultimately made from physical matter of one kind or another. Finally, it argues that for Aristotle the basic properties of matter, including the basic properties of the material elements, cannot be understood teleologically. (shrink)

Much of the debate about Aristotle’s criticisms of Plato has focused on the separability of the Forms. Here the dispute has to do with the ontological status of the Forms, in particular Plato’s claim for their ontological priority in relation to perceptible objects. Aristotle, however, also disputes the explanatory and causal roles that Plato claims for the Forms. This second criticism is independent of the first; even if the problem of the ontological status of the Forms were resolved to Aristotle’s (...) satisfaction, this second criticism would still stand. The problem here is not that there is no room for Aristotle’s four causes in Plato’s ontology; on the contrary, antecedents for all four can be found in Plato’s works. The problem, instead, is that Plato’s Forms fail to meet the general requirements that Aristotle sets out for the material, efficient, formal, and final causes of perceptible objects. Hence, even if the Forms were immanent in perceptible objects, they would still explain nothing about them. (shrink)

In the context of Aristotle's metaphysics and natural philosophy, 'prime matter' refers to that material cause which is both the proximate material cause of the four sublunary elements and the ultimate material cause of all perishable substances. On the traditional view, prime matter is pure potentiality, without any determinate nature of its own. Against this view, I argue that prime matter must be physical, extended, and movable matter if it is to fulfil its role as the substratum persisting through the (...) generation and corruption of these elements and the individuating subject in which their defining properties are found.

Some commentators have argued that there is no room in Aristotle's natural science for simple, or unconditional, physical necessity, for the only necessity that governs all natural substances is hypothetical and teleological. Against this view I argue that, according to Aristotle, there are two types of unconditional physical necessity at work in the material elements, the one teleological, governing their natural motions, and the other non-teleological, governing their physical interaction. I argue as well that these two types of simple necessity (...) also govern everything made out of the elements, that is, all other natural substances and artifacts. (shrink)

RÉSUMÉBeaucoup ont soutenu qu'il n'y a pas de place pour des expériences scientifiques dans les sciences naturelles d'Aristote : les expériences interviennent dans la nature, mais Aristote soutient que nous devons simplement observer la nature; si nous intervenions, le résultat serait quelque chose d'artificiel ou contraire à la nature. Contre cela, je soutiens qu'Aristote a non seulement effectué des expériences scientifiques, mais a également maintenu qu'il y a beaucoup de connaissances sur la nature qui peuvent être découvertes expérimentalement.

Gregory Vlastos has argued that Aristotle and other commentators on the Phaedo have mistakenly interpreted Plato’s Forms to be efficient causes. While Vlastos is correct that the Forms by themselves are not efficient causes, because of his neo-Kantianism he has misunderstood the close connection between the Forms and the explanation of change, including teleological change. This paper explores the connection in Plato’s Phaedo between the Forms, the nature of change, and efficient causality, and argues that Aristotle’s remarks are not as (...) misplaced as Vlastos claims.

In his metaphysics and natural philosophy, Aristotle uses the concept of a material cause,i.e., that from which something can be made or generated. This paper argues that Aristotle also has a concept of matter in the sense of physical stuff. Aristotle develops this concept of matter in the course of investigating the material causes of perceptible substances. Because of the requirements for change, locomotion, and the physical interaction of material objects, Aristotle holds that all perceptible substances must be extended in (...) three dimensions, movable, and corporeal due to their material causes. Thus, perceptible substances are physical substances because they are made out of something physical. (shrink)

Aristotle uses two kinds of material cause in his analysis of biological organisms: compositional matter, which persists through their birth and death;and functional matter, which consists of the organs and functional parts out of which biological organisms are made while they are alive. These two kinds of material cause, it has been argued, have quite different explanatory roles: functional matter is required by biological organisms to perform their essential functions,but compositional matter contributes nothing necessary to them and is only responsible (...) for their accidental properties. Against this view, I argue that biological organisms are systematically dependent upon their compositional matter and the latter is responsible for many of their necessary attributes. (shrink)

In traditional and popular accounts, Zen Buddhism is depicted as a practice that rejects literary study and intellectualization in favor of a direct experience of enlightenment that is beyond words. Indeed, the Zen school has traditionally defined itself as a "separate transmission outside the teachings, not dependent on words and letters". Even when regarding the tradition's literary output, Zen literature is famous for its antinomian dialogues replete with outrageous antics, frequent non sequiturs, and crude, illiterate utterances that appear to validate (...) the perspective that Zen simply rejects logical thinking, rational discourse, literary cultivation, and any systematic means of study. While it is... (shrink)

Formal approaches that aim at representing human reasoning should be evaluated based on how humans actually reason. One way of doing so is to investigate whether psychological findings of human reasoning patterns are represented in the theoretical model. The computational logic approach discussed here is the so-called weak completion semantics which is based on the three-valued ᴌukasiewicz logic. We explain how this approach adequately models Byrne’s suppression task, a psychological study where the experimental results show that participants’ conclusions systematically (...) deviate from the classical logically correct answers. As weak completion semantics is a novel technique in the field of computational logic, it is important to examine how it corresponds to other already established non-monotonic approaches. For this purpose we investigate the relation of weak completion with respect to completion and three-valued stable model semantics. In particular, we show that well-founded semantics, a widely accepted approach in the field of non-monotonic reasoning, corresponds to weak completion semantics for a specific class of modified programs.

Seventeenth-century advancements in physical science are often presented as overthrowing the Aristotelian tradition; perhaps Aristotle's emphasis on formal and final causes left little room for a physical theory grounded in material and efficient causes. In Aristotle's Science of Matter and Motion, Christopher Byrne argues that Aristotle is not to blame, as he indeed possessed a unified theory of matter and motion. In contrast to traditional interpretations, which place an undue explanatory burden on formal and final causes, Byrne (...) argues that Aristotle's theory of the physical world is dependent on the features possessed by perceptible objects, qua perceptible, as well as non-teleological changes in matter.Byrne's...

One very popular framework in contemporary epistemology is Bayesian. The central epistemic state is subjective confidence, or credence. Traditional epistemic states like belief and knowledge tend to be sidelined, or even dispensed with entirely. Credences are often introduced as familiar mental states, merely in need of a special label for the purposes of epistemology. But whether they are implicitly recognized by the folk or posits of a sophisticated scientific psychology, they do not appear to fit well with perception, as is (...) often noted. -/- This paper investigates the tension between probabilistic cognition and non-probabilistic perception. The tension is real, and the solution—to adapt a phrase from Quine and Goodman—is to renounce credences altogether. (shrink)

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological.

In an age where issues like climate change and the unintended consequences of technological innovation are high on the ethical and political agenda, questions about the nature and extent of our responsibilities to future generations have never been more important, yet simultaneously so difficult to answer. This book takes a unique approach to the problem by drawing on diverse traditions of thinking about care (including developmental psychology, phenomenology and feminist ethics) to explore the nature and meaning of our relationship with (...) the future. Demonstrating that many influential perspectives on intergenerational ethics, including positions advanced by John Rawls, Brian Barry, and Ulrich Beck are undermined by problems relating to uncertainty, it shows that an approach based on care ethics can confront the uncertain future successfully and give a viable account of the nature and scope of future-oriented responsibilities.

This comment mainly examines Yli-Vakkuri and Hawthorne’s preferred framework for examining whether narrow content is viable, arguing that their framework is not well-suited to the task; once a more traditional framework is adopted, Y&H’s case against internalism is strengthened.

This paper accomplishes two tasks. First, I unpack Husserl’s analysis of interest from his 1893 manuscript, “Notes Towards a Theory of Attention and Interest” to demonstrate that it comprises his first rigorous genetic analysis of attention. Specifically, I explore Husserl’s observations about how attentive interest is passively guided by affections, moods, habits, and cognitive tensions. In doing so, I reveal that the early Husserl described attention as always pulled forward to new discoveries via the rhythmic recurrence of tension and pleasure. (...) Second, I demonstrate that “Notes” is the germ of Husserl’s mature genetic phenomenology of attention. The 1893 analysis provides Husserl with all of the philosophical reasons and tools for the construction of his genetic account of attention in his late works. I then discuss how the disclosure of this novel subterranean link can prompt a rethinking of the development of phenomenology. (shrink)

Three arguments for the thesis that sex is socially constructed are examined and rejected. No such argument could succeed, because sex is not socially constructed.

The terminology surrounding the dispute between higher-order and first-order theories of consciousness is piled so high that it sometimes obscures the view. When the debris is cleared away, there is a real prospect.

Some things are _about_, or are _directed on_ , or _represent_, other things. For example, the sentence 'Cats are animals' is about cats (and about animals), this article is about intentionality, Emanuel Leutze's most famous painting is about Washington's crossing of the Delaware, lanterns hung in Boston's North Church were about the British, and a map of Boston is about Boston. In contrast, '#a$b', a blank slate, and the city of Boston are not about anything. Many mental states and events (...) also have "aboutness": the belief that cats are animals is about cats, as is the fear of cats, the desire to have many cats, and seeing that the cats are on the mat. Arguably some mental states and events are not about anything: sensations, like pains and itches, are often held to be examples. Actions can also be about other things: hunting for the cat is about the cat, although tripping over the cat is not. This -- rather vaguely characterized -- phenomenon of "aboutness" is called _intentionality_. Something that is about (directed on, represents) something else is said to "have intentionality", or (in the case of mental states) is said to be an "intentional mental state". (shrink)
