In the last few years there has been an explosion of philosophical interest in perception; after decades of neglect, it is now one of the most fertile areas for new work. Perceptual Experience presents new work by fifteen of the world's leading philosophers. All papers are written specially for this volume, and they cover a broad range of topics dealing with sensation and representation, consciousness and awareness, and the connections between perception and knowledge and between perception and action. This will be the book on the philosophy of perception, a fascinating resource for philosophers and psychologists.

In discussions of perception and its relation to knowledge, it is common to distinguish what one comes to believe on the basis of perception from the distinctively perceptual basis of one's belief. The distinction can be drawn in terms of propositional contents: there are the contents that a perceiver comes to believe on the basis of her perception, on the one hand; and there are the contents properly attributed to perception itself, on the other. Consider the content.

Rabern and Rabern (2008) have noted the need to modify `the hardest logic puzzle ever’ as presented in Boolos 1996 in order to avoid trivialization. Their paper ends with a two-question solution to the original puzzle, which does not carry over to the amended puzzle. The purpose of this note is to offer a two-question solution to the latter puzzle, which is, after all, the one with a claim to being the hardest logic puzzle ever.

Frank Jackson has a new objectivist and representationalist account of the content of colour-experience. I raise several objections both against the account itself and, primarily, against how he tries to support it. He argues that the new account enables us to see what is wrong with the so-called Opacity Puzzle. This alleged puzzle is an argument in which a seemingly implausible conclusion is derived from three premises of which seem plausible to an representationalist. Jackson’s diagnosis of the puzzle as a fallacy of equivocation is mistaken. The term ‘‘the property of being red’’ is not ambiguous in the way he claims it to be, and the puzzling argument is valid. Moreover, its conclusion is not implausible, so after all there is no real puzzle. I try to show how Jackson’s wrong diagnosis results from neglecting the difference between properties proper and properties as conceived in the light of a given property-concept.

We present the simplest solution ever to 'the hardest logic puzzle ever'. We then modify the puzzle to make it even harder and give a simple solution to the modified puzzle. The final sections investigate exploding god-heads and a two-question solution to the original puzzle.

In his latest book, Roy Sorensen offers a solution to a puzzle he put forward in an earlier article -The Disappearing Act. The puzzle involves various question about how the causal theory perception is to be applied to the case of seeing shadows. Sorensen argues that the puzzle should be taken as bringing out a new way of seeing shadows. I point out a problem for Sorensen’s solution, and offer and defend an alternative view, according to which the puzzle is to be interpreted as showing a new way of seeing objects, in virtue of their contrast with light.

In examining the puzzle of experience, and its possible solutions, Valberg discusses relevant views of Hume, Kant, Heidegger, Wittgenstein, and Strawson, as well as ideas from the recent philosophy of perception. Finally, he describes and analyzes a manifestation of the puzzle outside philosophy, in everyday experience.
