Synaesthetes persistently perceive certain stimuli as systematically accompanied by illusory colours, even though they know those colours to be illusory. This appears to contrast with cases where a subject’s colour vision adapts to systematic distortions caused by wearing coloured goggles. Given that each case involves longstanding systematic distortion of colour perception that the subjects recognize as such, how can a theory of colour perception explain the fact that perceptual adaptation occurs in one case but not the other? I argue that (...) these cases and the relationship between them can be made sense of in light of an existing view of colour perception. Understanding colours as ways in which objects and surfaces modify light, perceived through grasping patterns and variations in colour appearances, provides a framework from which the cases and their apparent disanalogy can be predicted and explained. This theory’s ability to accommodate these cases constitutes further empirical evidence in its favour. (shrink)

We present a specific elaboration and partial defense of the claims that cognition is enactive, embodied, embedded, affective and (potentially) extended. According to the view we will defend, the enactivist claim that perception and cognition essentially depend upon the cognizer’s interactions with their environment is fundamental. If a particular instance of this kind of dependence obtains, we will argue, then it follows that cognition is essentially embodied and embedded, that the underpinnings of cognition are inextricable from those of affect, that (...) the phenomenon of cognition itself is essentially bound up with affect, and that the possibility of cognitive extension depends upon the instantiation of a specific mode of skillful interrelation between cognizer and environment. Thus, if cognition is enactive then it is also embodied, embedded, affective and potentially extended. (shrink)

I consider whether there is a plausible conception of personal identity that can accommodate the ‘Multiplicity Thesis’ (MT), the thesis that some ways of creating and deploying multiple distinct online personae can bring about the existence of multiple persons where before there was only one. I argue that an influential Kantian line of thought, according to which a person is a unified locus of rational agency, is well placed to accommodate the thesis. I set out such a line of thought (...) as developed by Carol Rovane, and consider the conditions that would have to be in place for the possibility identified by MT to be realised. Finally I briefly consider the prospects for MT according to neo-Lockean and animalist views of personhood. (shrink)

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, (...) but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.

How should we understand the relationship between conscious perception and action? Does an appeal to action have any place in an account of colour experience? This essay aims to shed light on the first question by giving a positive response to the second. I consider two types of enactive approach to perceptual consciousness, and two types of account of colour perception. Each approach to colour perception faces serious objections. However, the two views can be combined in a way that resists (...) the criticisms to each. Furthermore, the hybrid view we arrive at lets us see which enactive account of perceptual consciousness we should prefer in the case of colour. (shrink)

Information and communication technologies (ICTs) are building a new habitat (infosphere) in which future generations will spend an increasing amount of time. So, how individuals construct, shape and maintain their personal identities online (PIOS) is a problem of growing and pressing importance. Today, PIOs can be created and developed, as an ongoing work-in-progress, to provide experiential enrichment, expand, improve or even help to repair relationships with others and with the world, or enable imaginative projections (the "being in someone else's shoes" (...) experience), thus fostering tolerance. However, PIOs can also be mis-constructed, stolen, "abused", or lead to.. (shrink)
