A cluster of experiments on “Change Blindness”, “Inattentional Blindness” and associated phenomena appear to demonstrate extremely counter intuitive results. According to one plausible characterisation, these results show that we consciously take in far less of the visual world than it seems we are aware of. It is worth briefly summarising the results of two recent sets of experiments, in order to give a flavour of this work. In ‘Gorillas in our Midst’ (Simons, D. and Chabris, C., Perception, 1999, 28), subjects were asked to perform a task that involved watching a video of a casual basketball game that lasts for about a minute. The task involves counting the number of consecutive passes between members of the one of the teams. While the basketball is being thrown from player to player, something unexpected takes place: a person dressed in a black gorilla-suit walks through the play, stops briefly in the centre of the picture, thumps his chest, and then walks off. Although most subjects correctly record the number of passes made by the team, at least half of these subjects fail to notice the gorilla-suited interloper, who is visible for about nine seconds. When shown the video sequence a second time they are amazed to observe what they had previously overlooked.

The issue of what distinguishes systems which have original intentionalityfrom those which do not has been brought into sharp focus by Saul Kripke inhis discussion of the sceptical paradox he attributes to Wittgenstein.In this paper I defend a sophisticated version of the dispositionalistaccount of meaning against the principal objection raised by Kripke in hisattack on dispositional views. I argue that the objection put by the sceptic,to the effect that the dispositionalist cannot give a satisfactory account ofnormativity and mistake, in fact comprises a number of distinct lines ofargument, all of which can be satisfactorily answered by the dispositionalist.

This paper examines the contents of perceptual experience, and focuses in particular on the relation between the representational aspects of an experience and its phenomenal character. It is argued that the Critical Realist two-component analysis of experience, advocated by Wilfrid Sellars, is preferable to the Intentionalist view. Experiences have different kinds of representational contents: both informational and intentional. An understanding of the essential navigational role of perception provides a principled way of explaining the nature of such representational contents. Experiences also have a distinct phenomenal content, or character, which is not determined by representational content.

What are phenomenal qualities, the qualities of conscious experiences? Are phenomenal qualities subjective, belonging to inner mental episodes of some kind, or should they be seen as objective, belonging in some way to the physical things in the world around us? Are they physical properties at all? And to what extent do experiences represent the things around us, or the states of our own bodies? Fourteen original papers, written by a team of distinguished philosophers and psychologists, explore the ways in which phenomenal qualities fit in with our understanding of mind and reality. This volume offers an indispensable resource for anyone wishing to understand the nature of conscious experience.
