In this paper I first address what I consider a central issue in the account of perception in Plato’s Timaeus, namely, how the pathemata pass through the body to reach the soul, and thus become aistheseis. My point in Section 1 is that in tackling this issue Plato aims to provide a firm physiological basis to the notion of perception that starts to emerge in the Theaetetus and the Philebus and is crucial to the late development of his theory of (...) cognition. In the ensuing section I try to put the account of perception in the Timaeus into a historical perspective, aiming to highlight two points: a) Plato’s description of the way in which sensible impressions “travel” inside the body and interact with its parts and other constituents is largely indebted to previous theories, such as those we find, for example, in Empedocles and a few Hippocratic writers; b) The leading role in this story (where internal air plays a significant supporting role) is played by blood flowing through the vascular system and thus performing a crucial cognitive function. Moreover, emphasizing the role of blood as well as analyzing the elaborate way in which perceptions are transmitted through the body to the soul proves vital to appreciate (in Section 3) the cognitive status of the lower parts of the soul (which are more involved in perception) and their relation to reason. Overall, the paper adds further elements to our understanding of Plato’s embodied approach to cognition. I had already written (and submitted) this article when Johansen (2021) was published. The latter’s approach to the role of blood in Plato’s physiology of knowledge in the Timaeus converges in part with mine (as I was pleased to find out), partly due to our overlapping sources and bibliography.

The paper aims to show that ανoια is the general term for the diseases of the soul, and that μανία and αμαϑία are not necessarily two distinct species but two levels of the same disease: ignorance signifies the cognitive state, whereas madness indicates both a cognitive state and a specific phenomenal character. Plato's other remarks on psychic ailments can be incorporated into this account. The result can also be accommodated to the general theory of the soul–body relationship in the dialogue. (...) Incarnated souls cannot work without the corresponding activity of the body, even if this does not rule out the possibility for the soul to exist in a discarnate state. (shrink)

The Politics of Orientation provides the first substantial exploration of a surprising theoretical kinship and its rich political implications, between Gilles Deleuze's philosophy and the sociological systems theory of Niklas Luhmann. Through their shared theories of sense, Hannah Richter draws out how the works of Luhmann and Deleuze complement each other in creating worlds where chaos is the norm and order the unlikely and yet remarkably stable exception. From the encounter between Deleuze and Luhmann, Richter develops a novel take on (...) postfoundational ontology where subjects and societies unfold in self-productive relations of sense against a background of complexity. The Politics of Orientation breaks and rebuilds theoretical alliances by reading core concepts and thinkers of Continental Philosophy, from Leibniz to Whitehead and Marx, through this encounter. Most importantly, the book puts Luhmann and Deleuze to work to offer urgently needed insight into the rise of post-truth populism. In our complex democratic societies, Richter argues, orientation against complexity has become the ground of political power, privileging the simplistic narratives of the populist right. (shrink)

This paper argues that the duality of phantasia consists not in its being divided between two faculties, but in its being the meeting point of two representations. First it is argued that Plotinus’ theory, according to which the representation is a judgement, rests on his reading of Theaetetus 184c–187a and its criticism in De Anima III, 2–3. Second, it is argued that the ‘image’ in which the Plotinian representation consists follows the perceptual judgement instead of preceding it. Third, it is (...) argued that there is neither a sub-sensitive faculty of phantasia nor a sub-sensitive representation. Then, the exteriority of the objects of representation with respect to the soul is discussed. Finally, an interpretation is proposed concerning the necessity for Plotinus to posit two representations of the same object. (shrink)

Selon Platon, la sensation n’est assurément pas en elle-même et par ellemême épistémique, car la science ne comporte rien de sensible, puisqu’elle advient sans l’intervention du corps, tandis que la sensation est précisément une affection qui unit âme et corps dans un même mouvementCe point fait l’objet d’un long passage du Théétète, au cours duquel la thèse de Protagoras selon laquelle science et sensation sont identiques est réfutée. Ceci est bien connu, mais il importe néanmoins de clarifier la raison pour (...) laquelle Platon invalide cette identité, ce qui rend impossible l’assimilation de la sensation à la science, que celle-ci soit, du reste, intuitive ou judicative.

In the second century of our era the Athenian Platonist, Atticus, claimed that it was clear not only to philosophers but perhaps even to ordinary people that the heritage left by Plato was the immortality of the soul. Plato had expounded the doctrine in various and manifold ways and this was about the only thing holding together the Platonic school. Atticus is but one witness to the prominence accorded the soul in discussions and debates among later Platonists. But while questions (...) concerning the origin, constitution, and destiny of the human soul are relatively well attested for Middle Platonism, not to mention Neoplatonism, we know much less about these topics among Plato's immediate successors in the Academy, Speusippus of Athens and Xenocrates of Chalcedon . Both wrote treatises on the soul , but these have been lost along with their other, numerous writings. Because the least that can be said is that Speusippus and Xenocrates upheld the immortality of the soul , any snippet of information that might tell us more deserves close consideration. (shrink)

In the second century of our era the Athenian Platonist, Atticus, claimed that it was clear not only to philosophers but perhaps even to ordinary people that the heritage left by Plato was the immortality of the soul. Plato had expounded the doctrine in various and manifold ways (ποικίλως καì παντοίως) and this was about (σχεδόν) the only thing holding together the Platonic school. Atticus is but one witness to the prominence accorded the soul in discussions and debates among later (...) Platonists. But while questions concerning the origin, constitution, and destiny of the human soul are relatively well attested for Middle Platonism, not to mention Neoplatonism, we know much less about these topics among Plato's immediate successors in the Academy, Speusippus of Athens (c. 408–339) and Xenocrates of Chalcedon (396–314). Both wrote treatises on the soul (περì ψυχ⋯ς), but these have been lost along with their other, numerous writings. Because the least that can be said is that Speusippus and Xenocrates upheld the immortality of the soul (as would be expected), any snippet of information that might tell us more deserves close consideration.

The goal of this paper is to examine the cognitive limits of aisthêsis in 184-6 of Plato’s Theaetetus. The options are: aisthêsis as ‘bare sensation’ and aisthêsis as ‘perceptual judgment’. I argue that Plato ignores the tension between these two alternatives because he is describing the whole process of perception as containing both. My focus is the text at 184-5, but first I make some preliminary comments, from a synoptic perspective, about what Plato is doing in the context of the (...) argument. After that, I move on the text, offering translations and interpretations of the relevant parts. I also discuss some of Cornford and Cooper’s ideas about Theaetetus 184-6. (shrink)
