I am very grateful to my commentators for their interest and their careful attention to A Theory of Sentience. It is particularly gratifying to find other philosophers attracted to the murky domain of pre-attentive sensory processing, an obscure place where exciting stuff happens. I can by no means answer all of their objections or counter-arguments, and some of the problems noted derive from failures in my original exposition. But a theory is a success if it helps spur the creation of better successors. By those lights this one seems to be succeeding admirably. Would that every author could receive such commentaries!

In Clark (2000), Austen Clark argues convincingly that a widespread view of perception as a complicated kind of feature-extraction is incomplete. He argues that perception has another crucial representational ingredient: it must also involve the representation of "sensory individuals" that exemplify sensorily extracted features. Moreover, he contends, the best way of understanding sensory individuals takes them to be places in space surrounding the perceiver. In this paper, I'll agree with Clark's case for sensory individuals (.

In his book A Theory of Sentience, Austen Clark argues that the content of sensory representations can be expressed as sentences constructed from a language of sentience. Such sentences specify that a determinate feature obtains in a particular space-time region, but the language's limited vocabulary prohibits the sentences from referring or attributing features to objects. In this paper, I show that this view is flawed in at least two ways. First, if sensation has the capacities that Clark and others attribute to it, then the vocabulary of sense extends further than he supposes, and a limited language of sentience cannot justify a prohibition of object representation within sentience. Second, even if the language of sentience is as impoverished as he claims, and thus even if the representational capacity of sentience is correspondingly limited, object individuation can plausibly occur at the level of sensation. In the course of defusing Clark's major argument for an “object-less” theory of sentience, I offer reasons to believe both that sensory representations can be impressively sophisticated in what they say about the world, and that object representations can be surprisingly basic.

The paper argues that material objects are the primary referents of visual states -- not places, as Austen Clark would have it in his A Theory of Sentience.
