Ted Honderich, 74, formerly Grote Professor of the Philosophy of Mind and Logic at the University of London, recently published a short book on consciousness (Honderich, 2004). Colin McGinn, 57, his former colleague at University College London and now a professor of philosophy at the University of Miami, Florida, reviewed it (McGinn, 2007a). The review is quite long and detailed, but the first sentences set the tone. McGinn on Honderich: 'This book runs the full gamut from the mediocre to the ludicrous to the merely bad. It is painful to read, poorly thought out, and uninformed. It is also radically inconsistent.'.

It is hard not to sympathise with Professor Honderich's starting point. It is easy to feel pessimistic about philosophy's ability to throw light on the nature of consciousness. What, then, to do? One option is to persist with the various current approaches. It is clear that Honderich thinks this would be akin to putting more effort into trying to work out the temporal priority of the chicken and the egg. The thought of the orthodox is that an account of consciousness is going to be either fundamentally materialist or fundamentally dualist. The first of these is untenable as consciousness has other or more than neural properties. The second is untenable for various reasons, Honderich's favoured one being that it renders consciousness as out of space and of a mysterious nature. A second option would be to follow Colin McGinn's lead, and think that the problem is of such a nature that it is necessarily unsolvable (McGinn, 1989). Alternatively, we should be more radical and think creatively, not necessarily respecting our current conceptual boundaries between the mental and the physical, the inside and the outside. The solution, Honderich says, lies in the thought that `my consciousness now consists in the existence of a world' (Honderich, 2004, p. 130). I shall say a little about what I understand by this claim, by raising what I take to be three obvious questions, looking at Honderich's answers them, and inviting some further clarification. Throughout I will address only the question of perceptual consciousness.

Honderich claims that for a person to be perceptually conscious is for a world to exist. I decide what this means, and whether it could be true, in the opening section Consciousness and Existence. In Honderich's Phenomenology, I show that Honderich's theory is essentially anticipated in the ideas and Ideas of Husserl. In the third section, Radical Interiority, I argue that although phenomenology putatively eschews ontology of mind, and Honderich construes his position as near- physicalism, Honderich's insights are only truths because we are spiritual substances.

Professor Honderich presents his account of consciousness boldly and informally, and his presentation merits a response in similar terms. I conceive of this response as simply the first move in a conversation, in the course of which misunderstandings might be removed and, just possibly, criticisms sharpened, and positions modified. I want to concentrate on two questions that his very interesting paper prompts me to ask. The first question is; what exactly is the thesis about consciousness that Professor Honderich is proposing? The second question is; what are the main reasons he has for his proposal and are they persuasive? Although there are two questions, I shall mix considerations of them together in a way which I hope it is possible to follow.

Ted Honderich's 'Radical Externalism' concerning the nature of consciousness is a refreshing, and in many ways very appealing, approach to a long- standing and seemingly intractable philosophical conundrum. Although I sympathize with many of his motivations in advancing the theory and share his hostility for certain alternative approaches that are currently popular, I will serve him better by playing devil's advocate than by simply recording my points of agreement with him. If his theory is a good one, it should be able to stand up to the strongest criticisms that we can muster against it. I shall do my best to articulate some of those criticisms as forcefully as I can.

Ted Honderich's theory of consciousness as existence, which he here calls Radical Externalism, starts with a good phenomenological observation: that perceptual experience appears to involve external things being immediately present to us. As P.F. Strawson once observed, when asked to describe my current perceptual state, it is normally enough simply to describe the things around me (Strawson, 1979, p. 97). But in my view that does not make the whole theory plausible.
