In the Timaeus, plants are granted soul, and specifically the sort of soul capable of perception and desire. Also in the Timaeus, perception requires the involvement of to phronimon. It seems it must follow that plants are intelligent. I argue that we can neither avoid granting plants sensation in just this sense, nor can we suppose that `to phronimon' is something devoid of intelligence. Indeed, plants must be related to intelligence, if they are to be both orderly and good. Plants (...) must have individual souls if they are to be distinguished from each other, each with an orderly life; but the intelligence their perceptions require is not similarly individuated, for their ultimate good is only derivative: it is only as completing the body of the cosmos that plants are good things. Plants have their own perceptions and desires in virtue of the intelligence ordering the cosmos as a whole. (shrink)

In the present paper, I argue that in order to be in a position to understand what the World Soul thinks about, we need first to answer the question of whether the universe perceives and if so, of what it perceives. I shall first (section ) lay out the main reasons for suspecting that the universe has perception and some possible objections against this view. I will then (section ) make a case for my claim that the universe has perception (...) on the basis of my ‘minimalist’ account of perception, which identifies four necessary and jointly sufficient conditions for having an instance of aisthēsis: 1) a body; 2) a soul; 3) affections which cause motion/change in the body and in the soul; 4) the cause of these affections. I will show that the universe composed of a World Body and a World Soul meets all four conditions. On the basis of this, I will claim that one can ascribe (self-) perception to the universe. Finally (section ), I will suggest that the universe perceives the polyhedra of its own body. (shrink)

This dissertation is a study of appetite in Plato’s Timaeus, Republic and Phaedrus. In recent research is it often suggested that Plato considers appetite (i) to pertain to the essential needs of the body, (ii) to relate to a distinct set of objects, e.g. food or drink, and (iii) to cause behaviour aiming at sensory pleasure. Exploring how the notion of appetite, directly and indirectly, connects with Plato’s other purposes in these dialogues, this dissertation sets out to evaluate these ideas. (...) By asking, and answering, three philosophically and interpretatively crucial questions, individually linked to the arguments of the dialogues, this thesis aims to show (i) that the relationship between appetite and the body is not a matter of survival, and that appetite is better understood in terms of excess; (ii) that appetite is multiform and cannot be defined in terms of a distinct set of objects; and (iii) that appetite, in Plato, can also pertain to non-sensory objects, such as articulated discourse. -/- Chapter one asks what the universe can teach us about embodied life. It argues that Plato, in the Timaeus, works with an important link between the universe and the soul, and that the account of disorder, irrationality and multiformity identifying a pre-cosmic condition of the universe provides a key to understanding the excessive behaviour and condition of a soul dominated by appetite. -/- Chapter two asks why the philosophers of the Republic’s Kallipolis return to the cave, and suggests that Plato’s notion of the noble lie provides a reasonable account of this. By exploring the Republic’s ideas of education, poetry and tradition, it argues that appetite – a multiform and appearance oriented source of motivation – is an essential part of this account. -/- Chapter three asks why Socrates characterizes the speeches of the Phaedrus as deceptive games. It proposes that this question should be understood in the light of two distinctions: one between playful and serious discourse and one between simple and multiform. It argues that the speeches of the Phaedrus are multiform games, and suggests that appetite is the primary source of motivation of the soul addressed, personified by Phaedrus. -/- . (shrink)
