It is sometimes claimed that the Kantian Ought Implies Can principle (OIC) rules out the possibility of moral dilemmas. A certain understanding of OIC does rule out the possibility of moral dilemmas in the sense defined. However I doubt that this particular formulation of the OIC principle is one that fits well with the eudaimonist framework common to ancient Greek moral philosophy. In what follows, I explore the reasons why Aristotle would not accept the OIC principle in the form in which it rules out the possibility of moral dilemmas.

The Phaedo is usually taken to be among Plato's metaphysically richest dialogues. Dilman argues that, at best, the views of Plato's Socrates are here free of the taint of metaphysics, or that worthwhile, nonmetaphysical theses are propounded alongside metaphysical ones. In these cases, Dilman attempts to separate out "Socrates' spiritual and moral perceptions" from the metaphysical claims. The latter are "a mystification of the grammar of the language in which such perceptions are expressed". Dilman's objection to such metaphysical theses is Wittgensteinian. When philosophy goes beyond the attempt to articulate the role that a certain discourse plays in our form of life and, instead, attempts to provide some philosophical justification or explanation for our form of life, it degenerates into incoherence. Such language ceases to "do work" and is then "idling."

Proclus' interpretation of the Timaeus confronts the question of whether the living being that is the Platonic cosmos perceives itself. Since sense perception is a mixed blessing in the Platonic tradition, Proclus solves this problem by differentiating different gradations of perception. The cosmos has only the highest kind. This paper contrasts Proclus' account of the world's perception of itself with James Lovelock's notion that the planet Earth, or Gaia, is aware of things going on within itself. This contrast illuminates several key differences between contemporary theories of perception and the neoplatonic world view. In particular, it argues that the neoplatonists had a radically different view of these matters because they assigned the property of truth not only to representations, but to objects as well.
