I argue that perception is necessarily situation-dependent. The way an object is must not just be distinguished from the way it appears and the way it is represented, but also from the way it is presented given the situational features. First, I argue that the way an object is presented is best understood in terms of external, mind-independent, but situation-dependent properties of objects. Situation-dependent properties are exclusively sensitive to and ontologically dependent on the intrinsic properties of objects, such as their (...) shape, size, and color, and the situational features, such as the lighting conditions and the perceiver’s location in relation to the perceived object. Second, I argue that perceiving intrinsic properties is epistemically dependent on representing situation-dependent properties. Recognizing situation-dependent properties yields four advantages. It makes it possible to embrace the motivations that lead to phenomenalism and indirect realism by recognizing that objects are presented a certain way, while holding on to the intuition that subjects directly perceive objects. Second, it acknowledges that perceptions are not just individuated by the objects they are of, but by the ways those objects are presented given the situational features. Third, it allows for a way to accommodate the fact that there is a wide range of viewing conditions or situational features that can count as normal. Finally, it makes it possible to distinguish perception and thought about the same object with regard to what is represented. (shrink)

I offer an explanation of how subjects are able to perceive the intrinsic spatial properties of objects, given that subjects always perceive from a particular location. The argument proceeds in two steps. First, I argue that a conception of space is necessary to perceive the intrinsic spatial properties of objects. This conception of space is spelled out by showing that perceiving intrinsic properties requires perceiving objects as the kind of things that are perceivable from other locations. Second, I show that (...) having such a conception of space presupposes that a subject represent her location in relation to perceived objects. More precisely the thesis is that a subject represents her location as the location from which she both perceives objects and would act in relation to objects were she to act. So I argue that perception depends on the capacity to know what it would be to act in relation to objects. (shrink)

This volume collects a number of Perry's classic works on personal identity as well as four new pieces, 'The Two Faces of Identity', 'Persons and Information', 'Self-Notions and The Self' and 'The Sense of Identity'. Perry's Introduction puts his own work and that of others on the issues of identity and personal identity in the context of philosophical studies of mind and language over the past thirty years.

This paper develops and defends the capacity view, that is, the view that the ability to perceive the perspective-independent or intrinsic properties of objects depends on the perceiver’s capacity to act. More specifically, I argue that self-location and spatial know-how are jointly necessary to perceive the intrinsic spatial properties of objects. Representing one’s location allows one to abstract from one’s particular vantage point to perceive the perspective-independent properties of objects. Spatial know-how allows one to perceive objects as the kind of (...) things that are perceivable from points of view other than one’s own and thus to perceive them as three-dimensional space occupiers.
