Abstract: Contemporary scientific and philosophical literature on perception often focuses on the relationship between perception and action, emphasizing the ways in which perception can be understood as geared towards action or ‘action-oriented’. In this paper I provide a framework within which to classify approaches to action-oriented perception, and I highlight important differences between the distinct approaches. I show how talk of perception as action-oriented can be applied to the evolutionary history of perception, neural or psychological perceptual mechanisms, the semantic content or phenomenal character of perceptual states, or to the metaphysical nature of perception. I argue that there are no straightforward inferences from one kind of action-oriented perception to another. Using this framework and its insights, I then explore the notion of action-oriented perceptual representation which plays a key role in some approaches to embodied cognitive science. I argue that the concept of action-oriented representation proposed by Clark and Wheeler is less straightforward than it might seem, because it seems to require both that the mechanisms of perceptual representation are action-oriented and that the content of these perceptual representations are action-oriented. Given that neither of these claims can be derived from the other, proponents of action-oriented representation owe us separate justification for each claim. I will argue that such justifications are not forthcoming in the literature, and that attempts to reconstruct them run into trouble: the sorts of arguments offered for the representational mechanisms being action-oriented seem to undermine the sorts of arguments offered for the representational content being action-oriented, and vice-versa.

Abstract: The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privileged access

Abstract: This paper contrasts two enactive theories of visual experience: the sensorimotor theory (O’Regan and Noë, Behav Brain Sci 24(5):939–1031, 2001; Noë and O’Regan, Vision and mind, 2002; Noë, Action in perception, 2004) and Susan Hurley’s (Consciousness in action, 1998, Synthese 129:3–40, 2001) theory of active perception. We criticise the sensorimotor theory for its commitment to a distinction between mere sensorimotor behaviour and cognition. This is a distinction that is firmly rejected by Hurley. Hurley argues that personal level cognitive abilities emerge out of a complex dynamic feedback system at the subpersonal level. Moreover reflection on the role of eye movements in visual perception establishes a further sense in which a distinction between sensorimotor behaviour and cognition cannot be sustained. The sensorimotor theory has recently come under critical fire (see e.g. Block, J Philos CII(5):259–272, 2005; Prinz, Psyche, 12(1):1–19, 2006; Aizawa, J Philos CIV(1), 2007) for mistaking a merely causal contribution of action to perception for a constitutive contribution. We further argue that the sensorimotor theory is particularly vulnerable to this objection in a way that Hurley’s active perception theory is not. This presents an additional reason for preferring Hurley’s theory as providing a conceptual framework for the enactive programme.
