Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

I examine the passages where Aristotle maintains that intellectual activity employs φαντάσματα (images) and argue that he requires awareness of the relevant images. This, together with Aristotle’s claims about the universality of understanding, gives us reason to reject the interpretation of Michael Wedin and Victor Caston, on which φαντάσματα serve as the material basis for thinking. I develop a new interpretation by unpacking the comparison Aristotle makes to the role of diagrams in doing geometry. In theoretical understanding of mathematical and (...) natural beings, we usually need to employ appropriate φαντάσματα in order to grasp explanatory connections. Aristotle does not, however, commit himself to thinking that images are required for exercising all theoretical understanding. Understanding immaterial things, in particular, may not involve employing phantasmata. Thus the connection that Aristotle makes between images and understanding does not rule out the possibility that human intellectual activity could occur apart from the body. (shrink)

I argue that the science of the soul only covers sublunary living things. Aristotle cannot properly ascribe ψυχή to unmoved movers since they do not have any capacities that are distinct from their activities or any matter to be structured. Heavenly bodies do not have souls in the way that mortal living things do, because their matter is not subject to alteration or generation. These beings do not fit into the hierarchy of soul powers that Aristotle relies on to provide (...) unity to ψυχή. Their living consists in their activities, not in having a capacity for activity.

Aristotle’s cryptic De Anima III 5 has precipitated an enormous volume of commentary, especially about the identity of what has come to be known as active intellect and how it relates to potential intellect. Some take active intellect to be the prime mover of Metaphysics Λ, others a hypostatic or cosmic principle (for example, an ideal Intellect, intellect associated with the tenth celestial sphere, etc.), and others a faculty, potentiality, or power of the human soul that is distinct in function, (...) office, or operation from potential intellect. But a very different, ontologically lightweight way of characterizing active and potential intellect can be reconstructed from fragments of a work by the only interpreter personally acquainted with Aristotle, his junior colleague, Theophrastus of Eresus. This reconstruction suggests various philosophically attractive solutions to notorious problems raised by Aristotle’s text. (shrink)

I offer a new interpretation of the passages where Aristotle maintains that intellectual activity employs φαντάσµατα (images). In theoretical understanding of mathematical and natural beings, we usually need to consciously employ appropriate φαντάσµατα in order to grasp explanatory connections. Aristotle does not, however, commit himself to thinking that images are required for exercising all theoretical understanding: understanding immaterial things, in particular, may not involve φαντάσµατα. Thus the connection that Aristotle makes between images and understanding does not rule out the possibility (...) that human intellectual activity could occur apart from the body. (shrink)

In De Anima I 4, Aristotle describes the intellect (nous) as a sort of substance, separate and incorruptible. Myles Burnyeat and Lloyd Gerson take this as proof that, for Aristotle, the intellect is a separate eternal entity, not a power belonging to individual humans. Against this reading, I show that this passage does not express Aristotle’s own views, but dialectically examines a reputable position (endoxon) about the intellect that seems to show that it can be subject to change. The passage’s (...) argument for the indestructibility of intellect via an analogy to perception does not fit with Aristotle’s own views. Aristotle thinks that perception operates via bodily organs, but denies this of understanding. He also requires separability from the body for indestructibility, something this analogy rules out. However, Aristotle’s Platonist interlocutors may well endorse such an argument. My dialectical interpretation best resolves the interpretative difficulties and explains its place in the larger context, Aristotle’s discussion of Platonist views on the soul. Aristotle presents a challenge to his insistence that the soul is subject to change, dialectically resolves that challenge, and then ends by reserving the right to give a different account of the intellect.
