Context: The dominant approach to the study of perception is representational/computational, with an emphasis on the achievements of the brain and the nervous system, which are taken to construct internal models of the world. Alternatives include ecological, embedded, embodied, and enactivist approaches, all of which emphasize the centrality of action in understanding perception. Problem: Despite sharing many theoretical commitments that lead to a rejection of the classical approach, the alternatives are characterized by important contrasts and points of divergence. Here we (...) focus on the enactive and ecological approaches, in particular, on how they construe the status of the environment and the content of perception. Method: We begin with a review of James Gibson’s ecological psychology, highlighting it as a psychology for all organisms not just humans. Against this backdrop, we consider enactivist arguments against direct perception - a central assertion of the ecological approach - and in favor of interpreting the activity of perceptual agents as a kind of construction of a perceptually meaningful world. Results: We assess the merits of this interpretation and we conclude that it cannot be grounded on fundamental principles such as thermodynamics and organism-environment mutuality. Implications: As a consequence, enactivism remains close to representationalism and entails a form of dualism. Constructivist content: We advance a criticism of the constructivist foundations of the enactive approach to perception. Perception-action mutuality at the heart of enactivism does not require mental construction; indeed, perception-action mutuality obviates construction. (shrink)

This article is detective work, not philosophy. J. S. Mill's Autobiography records that at the age of seven he read, in Greek, ‘the first six dialogues of Plato, from the Euthyphron to the Theaetetus inclusive’. Which were the other dialogues? On the arrangement common today, it would be Crito, Apology, Phaedo, Cratylus. On the arrangement common then, Theages and Erastai replace Cratylus, which makes seven dialogues. I show that this must be the answer by the evidence of James Mill's commonplace (...) books and his writings on Plato. These reveal which collected edition of Plato he owned and which he would want to own. Conditions for studying Plato in the original were much harder than we are used to. The inquiry highlights both the ideological purity of the education James Mill designed for his son, and the difficulties he faced in realizing his plan. (shrink)

It is a standing temptation for philosophers to find anticipations of their own views in the great thinkers of the past, but few have been so bold in the search for precursors, and so utterly mistaken, as Berkeley when he claimed Plato and Aristotle as allies to his immaterialist idealism. InSiris: A Chain of Philosophical Reflexions and Inquiries Concerning the Virtues of Tar-Water, which Berkeley published in his old age in 1744, he reviews the leading philosophies of antiquity and finds (...) them on the whole a good deal more sympathetic to his own ideas than the ‘modern atheism’, as he calls it, of Hobbes and Spinoza or the objectionable principles of ‘the mechanic and geometrical philosophers’ such as Newton. But his strongest and, I think, his most interesting claim is that neither Plato nor Aristotle admitted ‘an absolute actual existence of sensible or corporeal things’. (shrink)

The question contrasts two ways of expressing the role of the sense organ in perception. In one the expression referring to the sense organ is put into the dative case ; the other is a construction with the preposition δiá governing the genitive case of the word for the sense organ.

This is a close scrutiny of "De Anima II 5", led by two questions. First, what can be learned from so long and intricate a discussion about the neglected problem of how to read an Aristotelian chapter? Second, what can the chapter, properly read, teach us about some widely debated issues in Aristotle's theory of perception? I argue that it refutes two claims defended by Martha Nussbaum, Hilary Putnam, and Richard Sorabji: (i) that when Aristotle speaks of the perceiver becoming (...) like the object perceived, the assimilation he has in mind is ordinary alteration of the type exemplified when fire heats the surrounding air, (ii) that this alteration stands to perceptual awareness as matter to form. Claim (i) is wrong because the assimilation that perceiving is is not ordinary alteration. Claim (ii) is wrong because the special type of alteration that perceiving is is not its underlying material realisation. Indeed, there is no mention in the text of any underlying material realisation for perceiving. The positive aim of II 5 is to introduce the distinction between first and second potentiality, each with their own type of actuality. In both cases the actuality is an alteration different from ordinary alteration. Perception exemplifies one of these new types of alteration, another is found in the acquisition of knowledge and in an embryo's first acquisition of the power of perception. The introduction of suitably refined meanings of 'alteration' allows Aristotle to explain perception and learning within the framework of his physics, which by definition is the study of things that change. He adapts his standard notion of alteration, familiar from "Physics" III 1-3 and "De Generatione et Corruptione" I, to the task of accounting for the cognitive accuracy of (proper object) perception and second potentiality knowledge: both are achievements of a natural, inborn receptivity to objective truth. Throughout the paper I pay special attention to issues of text and translation, and to Aristotle's cross-referencing, and I emphasise what the chapter does not say as well as what it does. In particular, the last section argues that the textual absence of any underlying material realisation for perceiving supports a view I have defended elsewhere, that Aristotelian perception involves no material processes, only standing material conditions. This absence is as telling as others noted earlier. Our reading must respect the spirit of the text as Aristotle wrote it. (shrink)

Philosophical Thought in Russia in the Second Half of the 20th Century is the first book of its kind that offers a systematic overview of an often misrepresented period in Russia's philosophy. Focusing on philosophical ideas produced during the late 1950s – early 1990s, it reconstructs the development of genuine philosophical thought in the Soviet period and introduces those non-dogmatic Russian thinkers who saw in philosophy a means of reforming social and intellectual life. Covering such areas of philosophical inquiry as (...) philosophy of science, philosophical anthropology, the history of philosophy, activity approach as well as communication and dialogue studies, the volume presents and thoroughly discusses central topics and concepts developed by Soviet thinkers in that particular fields. Written by a team of internationally recognized scholars from Russia and abroad, it examines the work of well-known Soviet philosophers (such as Mikhail Bakhtin, Evald Ilyenkov and Merab Mamardashvili) as well as those important figures (such as Vladimir Bibler, Alexander Zinoviev, Yury Lotman, Georgy Shchedrovitsky, Genrich Batishchev, Sergey Rubinstein, and others) who have often been overlooked. By introducing and examining original philosophical ideas that evolved in the Soviet period, the book confirms that not all Soviet philosophy was dogmatic and tied to orthodox Marxism and the ideology of Marxism-Leninism. It shows Russian philosophical development of the Soviet period in a new light, as a philosophy defined by a genuine discourse of exploration and intellectual progress, rather than stagnation and dogmatism. In addition to providing the historical and cultural background that explains the development of the 20th-century Russian philosophy, the book also puts the discussed ideas and theories in the context of contemporary philosophical discussions showing their relevance to nowadays debates in Western philosophy. With short biographies of key thinkers, an extensive current bibliography and a detailed chronology of Soviet philosophy, this research resource provides a new understanding of the Soviet period and its intellectual legacy 100 years after the Russian Revolution.

There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)
