The study of colour has become familiar territory in anthropology, linguistics, art history and archaeology. Classicists, however, have traditionally subordinated the study of colour to form. By drawing together evidence from contemporary philosophers, elegists, epic writers, historians and satirists, Mark Bradley reinstates colour as an essential informative unit for the classification and evaluation of the Roman world. He also demonstrates that the questions of what colour was and how it functioned - as well as how it could be misused and (...) misunderstood - were topics of intellectual debate in early imperial Rome. Suggesting strategies for interpreting Roman expressions of colour in Latin texts, Dr Bradley offers alternative approaches to understanding the relationship between perception and knowledge in Roman elite thought. In doing so, he highlights the fundamental role that colour performed in the realms of communication and information, and its intellectual contribution to contemporary discussions of society, politics and morality.

Qualia are the elements of phenomenal consciousness -- the raw feels which constitute what it is like to be in a conscious mental state. Some claim that qualia are epiphenomenal properties -- mere by-products of brain function which are causally inert. Though this is an implausible theory, it is difficult to show that it is false. Here I present an ad hominem argument -- the argument from coincidence -- which shows that epiphenomenalism about qualia is explanatorily deficient because it leaves (...) unexplained a highly improbable state of affairs, and so we have good reason to suppose that qualitative properties must be causally efficacious, and must be so in virtue of their qualitative nature.

Purple Haze: The Puzzle of Consciousness, by Joseph Levine, is reviewed. The position that Levine takes in the current philosophical debate about consciousness is identified and the general approach of the essay outlined. I focus on two of the more important issues in the book - the conceivability argument against materialism, and the explanatory gap argument against dualism - and argue that Levine's argument against the former is unconvincing and his diagnosis of the source of the latter leads him into (...) problems. I suggest a more promising route. (shrink)

One recent attempt to capture the content of physicalism involves characterising it negatively in terms of the non-mental. This thesis is criticised on the grounds that it fails to provide a sufficient condition for an adequate characterisation of physicalism, since, from a global physicalist perspective, it has both nothing to say about other so-called non-physical entities and fails to exclude them from the fundamental entities that such an account must posit. This latter problem is also faced by a more local (...) form of physicalism – one that restricts itself to just the mental domain. Some possible responses from the physicalist are briefly discussed and dismissed, and it is suggested that the physicalist must have some implicit idea of what she means by ‘the physical’, an idea which must amount to more than simply ‘the non-mental’.
