In 'Illusionism as a Theory of Consciousness', Frankish argues for illusionism: the thesis that phenomenal consciousness does not exist, but merely seems to exist. Illusionism, he says, 'replaces the hard problem with the illusion problem -- the problem of explaining how the illusion of phenomenality arises and why it is so powerful'. The illusion of phenomenality is indeed quite powerful. In fact, it is much more powerful than any other illusion, in the sense that we face a very special and unique intuitive resistance when trying to accept that phenomenality is an illusion. This is bad news for illusionists, because this means that they cannot entirely model their explanation of the illusion of consciousness on the explanation of other illusions. Explaining this unique intuitive resistance to illusionism may therefore constitute the hardest aspect of the illusion problem. However, I think that this aspect of the problem is solvable. I will outline a possible solution, which is based on the hypothesis that our (illusory) introspective representations of phenomenal states characterize them as having unique epistemological properties and as playing a special epistemological role.

Illusionism about consciousness is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Embracing illusionism presents the theoretical advantage that one does not need to explain how consciousness arises from purely physical brains anymore, but only to explain why consciousness seems to exist while it does not. As Keith Frankish puts it, illusionism replaces the “hard problem of consciousness” with the “illusion problem.” However, a satisfying version of illusionism has to explain not only why the illusion of consciousness arises, but also why it arises with its particular strength: Notably, why we are so deeply reluctant to recognize the illusory nature of consciousness. Explaining our strong intuitive resistance to illusionism means solving what I call the “illusion meta-problem,” which I think is a part of the illusion problem. In this paper, I argue that current versions of illusionism are unable to solve the illusion meta-problem. I focus on two of the most promising recent illusionist theories of consciousness, and I show why they fail to explain the peculiar reluctance we encounter whenever we try to accept that consciousness is an illusion.

In a recent paper, Eric Schwitzgebel argues that if materialism about consciousness is true, then the United States is likely to have its own stream of phenomenal consciousness, distinct from the streams of conscious experience of the people who compose it. Indeed, most plausible forms of materialism have to grant that a certain degree of functional and behavioral complexity constitutes a sufficient condition for the ascription of phenomenal consciousness – and Schwitzgebel makes a case to show that the United States as a whole fulfills this condition. One way to avoid this counter-intuitive consequence of materialism about consciousness is to adopt what Schwitzgebel calls an “anti-nesting principle”: a principle that states that there can be no nested forms of phenomenal consciousness and that therefore a conscious whole cannot have parts that are themselves conscious. However, Schwitzgebel then proceeds in his paper to draw up various objections, notably based on thought experiments, in order to dismiss these kinds of “anti-nesting” principles. My aim in this paper is to present a version of a sophisticated anti-nesting principle that avoids Schwitzgebel’s objections. This principle is reasonable, intuitive, and as non-arbitrary as possible. Moreover, it can resist the objections mounted by Schwitzgebel against simple anti-nesting principles. This principle helps materialists avoid the implication that the United States has its own stream of consciousness, while granting consciousness to some entities which, in many cases, are intuitive instantiators of phenomenal consciousness. This principle therefore constitutes a way out for a materialist who wants to deny that the United States is conscious.

Dans « Représentationnalisme et langage privé », François Kammerer s’attache à la thèse dite du représentationnalisme qui, au regard de la conscience phénoménale, pose que les propriétés qualitatives d’une expérience consciente sont entièrement déterminées par ses propriétés représentationnelles ; de nombreux arguments ont été proposés en faveur de cette thèse, qui est devenue l’orthodoxie en philosophie de l’esprit contemporaine. L’auteur entend réfuter les arguments les plus significatifs, en se fondant sur des considérations de Wittgenstein sur l’impossibilité d’un « langage privé ».

The Phenomenal Concept Strategy is a popular strategy used to support physicalism in the realm of conscious experience. This Strategy accounts for dualist intuitions but uses the ways in which we think about our experiences to explain these intuitions in a physicalist framework, without any appeal to ontological dualism. In this paper, I will raise two issues related to the currently available versions of the Phenomenal Concept Strategy. First, most of the theories belonging to the Phenomenal Concept Strategy posit that phenomenal concepts are exceptional and sui generis concepts, and these theories can be shown to be largely ad hoc. Second, these theories may explain the existence of anti-physicalist intuitions, but they do not explain their persistence. My aim is to put forward a new theory of phenomenal concepts that can rise up to these challenges to the Phenomenal Concept Strategy. In my view, phenomenal concepts are not independent and sui generis concepts. On the contrary, they are closely related to our other epistemic concepts, especially our concepts of “justification”. Thinking about an experience means thinking about a specific kind of justification – an unjustified justification, or, in other words, an “ultimate seeming”. I will show why this explains the existence and the persistence of antiphysicalist intuitions in a non-ad hoc way.
