A Note on the Possibility of Silicon Brains and Fading Qualia

John Searle and David Chalmers have each invoked the silicon-brain thought experiment, though to very different effect. Searle uses the possibility of silicon brains to argue that there is no ontological connection between consciousness and causal/functional role. Chalmers, on the other hand, thinks the possibility of silicon brains is grounds for positing a nomological connection between functional structure and consciousness (the principle of organizational invariance). In this article I attempt to explain how they manage to draw such divergent conclusions from the very same thought experiment. I argue that Searle’s hypothesis of the Background coupled with the connection principle militate against his own interpretation of the silicon-brain thought experiment. This leaves him with no alternative, in his bid to undermine the principle of organizational invariance, but to assume the role of the apostate and disavow the silicon-brain thought experiment.

Poetics of Emptiness


Mysticism and the search for experiences of expanded consciousness are nothing new to the modern era, although their incorporation into the academic world is shakier. Robert Forman, writing in this journal, calls mysticism his ‘somewhat unusual but increasingly accepted field’ (Forman, 1998, p. 185) Forman calls the prima facie experience of mysticism the ‘pure consciousness event’ (PCE) where the practitioner becomes ‘utterly silent inside, as though in a gap between thoughts’. During this event, one becomes ‘completely perception and thought- free’. He defines the pure consciousness event as ‘a wakeful, but contentless . . . consciousness’ (p. 186).
 These experiences are reported in virtually all religious traditions. In Buddhism the essence of this state is captured in the term Sunyata, usually translated as ‘emptiness’, and Forman equates the PCE with ‘sunyata’ and ‘emptiness’ in his article (p. 190). The purpose of this present paper, which looks to literature more than religion, is to identify a number of poems and poets that speak directly to this state, and to propose that poetry writing and reading can even produce this state.

Binding in Dreams. The Bizarreness of Dream Images and the Unity of Consciousness

Binding can be described at three different levels: In neuroscience it refers to the integration of single-cell activities to form functional neural assemblies, especially in response to global stimulus properties; in cognitive science it refers to the integration of distributed modular input processing to form unified representations for memory and action, and in consciousness studies it refers to the unity of phenomenal consciousness (Revonsuo, 1999). To describe and explain the unity of consciousness, detailed phenomenological descriptions of binding at the phenomenal level and clarification of the underlying cognitive and neural mechanisms are required. The disunity of consciousness during dreaming is a fruitful avenue to study phenomenal binding and its mechanisms. The notion of the ‘bizarreness’ of dreams is closely related to the concept of ‘binding’: bizarreness can be reconceptualized as referring to different types of unusual combinations of features in the binding of dream images coherently together. The present study concentrates on the representation of human characters and the bizarreness found in these representations. We developed a rating scale that distinguishes different types of bizarreness on the basis of the unusual combinations of elements that are manifested in dream images. The data consisted of 592 dream reports in the home-based dream diaries of 52 students. The results indicate that about half of the human characters appearing in our dreams contain bizarre elements, and that certain types of bizarreness are more frequent than others. Phenomenal features intrinsic to the representation of a person (visual outlook, familiarity, semantic knowledge) are less frequently bizarre than is the external relation between the person and the context (for example, the place). Thus, binding the local features of a representation coherently together appears to be less prone to errors than binding several different information streams together into a coherent phenomenal model of the world.
