Aristotle's Abstract Ontology, Allan Bäck

The Society for Ancient Greek Philosophy Newsletter

Aristotle has a metaphysics of individual substances, substrata persisting through time that are neither in nor said of a subject. That I do not dispute. However, when we move from the individual to the universal, from perception to knowledge, Aristotle has a metaphysics of relations. This I will try to sketch out here.

Aristotle appeals to abstraction at key places in his philosophy. Somehow abstraction gets us to the first principles and to the objects of the most fundamental sciences. Somehow universals are abstracted from singulars and have no transcendent existence.

Aristotle never states his theory of abstraction formally or …

Plato On Episteme And Propositional Knowledge, Denis Vlahovic

The Society for Ancient Greek Philosophy Newsletter

Epistêmê cannot just be a matter of knowing a logos. Knowledge, it appears, is demonstrated not in the knowledge of any particular logos, but in the ability to defend a logos against refutation. It is precisely the latter ability that is characteristic of epistêmê. This ability, furthermore, cannot be imparted by means of a logos. For, no logos suffices to endow its possessor with the ability to defend it (i.e., the logos) against refutation.

Given that Plato appears to have believed that no knowledge of a logos—no matter how elaborate the logos—is sufficient for epistêmê, one can see why he …

A Quarrel Between The Ancients And The Moderns: Aristotle's Realism And Modern Skepticism, Michael Bowler

The Society for Ancient Greek Philosophy Newsletter

For Aristotle, the object as perceived and the subject as perceiving can only be understood with respect to the activity of perception itself and the unity it brings about between the perceived object and perceiving subject. This is a complex unity that requires further analysis and refinement. This unity is the ground of Aristotle’s “realism” with regard to perception. However, if this unity is dissolved into an external, synthetic connection between two dissimilar things only one of which we have access to, then it is at best problematic and perhaps impossible for us to discover anything about the other. This …

Material Alteration And Cognitive Activity In Aristotle's De Anima, John Sisko

The Society for Ancient Greek Philosophy Newsletter

In this paper, I would like to sketch my account of the relation between cognitive activity and material alteration within Aristotle's psychological theory. I will begin by suggesting a new framework through which to view the important issues (§2). I will then show that on Aristotle's account material alteration is required both for any episode of perception in animals taken generally (§3) and for any episode of thought in human beings (§4). Finally, I will examine Aristotle's rationale for supposing that material alteration is required for human thought (§5).
