I like to imagine Aristotelian and Kantian judgment flowing together. Moreover, I like to think that for both of them, thought is first and foremost an open-ended, discursive process of interpretation, and ultimately value judgment.
Applying Spinoza’s notion of conatus to Kant, Longuenesse well captures the idea that the Kantian unity of apperception as an achieved state is only a constantly renewed aim. The difference between what she calls the “mere capacity to judge” in Kant and what Aristotle means by thought that “is not actively any of the things that are until it thinks” basically comes down to the difference between a Kantian capacity and an Aristotelian being-in-potentiality. These notions are clearly related both conceptually and historically, but I have recently dwelt quite a bit on various historical transformations of what I take to be the Aristotelian notion of potentiality.
The latter would consist in something like multiform, branching spaces of alternate conditionals, with gradients of difference and consequence, affecting the actualization of ends and constituting a metaphorical topography of relative densities of possibility in our actual world. A Kantian capacity — even one that defines us — is still in some sense a capability we discretely “have”, whereas an Aristotelian potentiality pertains to our being, but also at the same time to that of the world we inhabit.
Aristotelian “thought” — commonly translated “intellect” — has been quite variously interpreted, and often fused with notions of neoplatonic or Augustinian provenance. Aristotle’s own texts dealing with it are quite minimalist. The relatively most extensive one is in On the Soul. I would complement it with what he says about practical judgment and ethos in the Ethics, and about the pursuit of wisdom in book Alpha of the Metaphysics. I take it to refer not to a mind-entity, or an intuitive knowledge, or an engine of predetermined reasoning, but rather to a discursive potentiality, an engagement in thought and valuation and earnest search, and the ethical “spirit” that is the undying essence of a human being.
