Our conscious experiences are said to possess a unique property called phenomenal consciousness. Why these and only these states of us have this property has proved to be an exceedingly difficult question for philosophers and scientists to answer. In fact, some have claimed that this question constitutes the hard problem of the mind-body problem, one which cannot be solved by the standard methods of contemporary science. In his most recent book, Phenomenal Consciousness, Peter Carruthers offers a bold, original and scientifically acceptable solution to this hard problem: the dispositional higher-order thought theory. I describe the main line of argument in Phenomenal Consciousness for Carruthers' dispositional HOT theory and present three places where the argument seems most vulnerable. I end the review with a very positive endorsement of Phenomenal Consciousness, recommending it as compulsory reading for anyone interested in the contemporary philosophical and scientific debate over the nature of phenomenal consciousness.

A persistent methodological problem in primate social cognition research has been how to determine experimentally whether primates represent the internal goals of other agents or just the external goals of their actions. This is an instance of Daniel Povinelli’s more general challenge that no experimental protocol currently used in the field is capable of distinguishing genuine mindreading animals from their complementary behavior-reading counterparts. We argue that current methods used to test for internal-goal attribution in primates do not solve Povinelli’s problem. To overcome the problem, a new type of experimental approach is needed, one which is supported by an alternative theoretical account of animal mindreading, called the appearance-reality mindreading (ARM) theory. We provide an outline of the ARM theory and show how it can be used to design a novel way to test for internal-goal attribution in chimpanzees. Unlike protocols currently in use, the experimental design presented here has the power, in principle and in practice, to distinguish genuine mindreading chimpanzees from those who predict others’ behavior solely on the basis of behavioral/environmental cues. Our solution to Povinelli’s problem has important consequences for a similar debate in developmental psychology over when preverbal infants should be credited with the ability to attribute internal goals. If what we argue for here in the case of nonhuman primates is sound, then the clearest tests for internal-goal attribution in infants will be those that test for attributions of discrepant or ‘false’ perceptions

David Rosenthal and Fred Dretske agree that creature consciousness should be used to give a reductive explanation of state consciousness. They disagree, however, over what type of creature consciousness will do the job. Rosenthal, defending a higher-order thought (HOT) account, argues that higher-order creature consciousness is what is needed. Dretske, defending a first-order (FO) account, argues that first-order creature consciousness is what is needed. I attempt to advance this debate by presenting a case for a third creature-conscious account of state consciousness. what I call the same-order (SO) account. I show that bydefining a conscious mental state as a mental state whose possessor is conscious of what it represents, we are offered a unique creature-conscious account of state consciousness that avoids some of the problems that have plagued both the HOT and FO accounts.
