On the alleged absurdity of substantially unconscious Greek minds. In: Marcel Kuijsten, ed., Reflections on the Dawn of Consciousness. AHP Press (forthcoming.
Abstract Upon publication in 1976, Julian Jaynes's Origin of consciousness in the Breakdown of the Bicameral Mind was immediately recognized as an extraordinary work. It was hailed by some as "probably the book of the century", and was nominated for the National Book Award in 1978. Now, on its thirtiest anniversary, it is all but forgotten, mainly because its boldest thesis (that the Mycenean Greeks had a 'bicameral mind' instead of a conscious mind of the modern type) was written off by critics as "patently absurd". This paper offers a critical re-examination of Jaynes’s boldest suggestion, and argues that it is anything but absurd.

Greek zombies, Philosophical psychology, forthcoming.
Abstract This paper explores the possibility that the human mind underwent substantial changes in recent history. Assuming that consciousness is a substantial trait of the mind, the paper focuses on the suggestion made by Julian Jaynes that the Mycenean Greeks had a 'bicameral' mind instead of a conscious one. The suggestion is commonly dismissed as patently absurd, for instance by critics such as Ned Block. A closer examination of the intuitions involved, considered from different theoretical angles (social constructivism, idealism, eliminativism, realism), reveals that the idea of 'Greek zombies' should be taken more seriously than is commonly assumed.

Patentontologie. Over de schoonheid van de taal bij Lucebert. In: Ria van den Brandt en Bart Philipsen, red., De waarheid waarover ik niets weet te zeggen Over poëzie en waarheid. Damon, Budel, 2004, pp. 51-59.
Abstract Glossing a famous work by the Dutch poet Lucebert, this paper explores the ideology behind "the dogma of the infallibility of language" (G.K. Chesterton). It is argued that the poetic use of language is radically different from what is commonly taken to be its 'ordinary' use in literary, scientific, and especially printed form. The intrinsically performative character of poetry, so it is argued, is cognate to pristine orality, and lies outside the reach of later inventions such as 'algorithmic hermeneutics' (conceptual frameworks) and 'patented ontology' (rationally regulated world view).

Intentionaliteit. In: M. Schouten, red., Vijftig jaar Philosophy of mind. Themanummer Wijsgerig Perspectief, 2001, pp. 000-000.
Abstract 'Intentionality' or 'aboutness' is often seen as the hallmark of mental phenomena, which sets the mind apart from the merely physical. In contemporary psychology, with its strongly physicalist tendencies, this notion has come under attack. This paper offers an overview of work on intentionality in modern philosophy of mind. Which factors (internal or external) are responsible for determining the 'contents' of the mind? Is intentionality a real property of certain types of being, or should it be seen as merely instrumental, or worse still, should it be eliminated?.

De kelders van cyberspace. In: Proceedings of the Symposium on Virtual Reality (May 1998), ETV, TU Delft, 1999.
Abstract A philosopher discusses the nature and use of virtual reality (VR) before an audience of electrotechnical engineers. After presenting a brief history of the notion of simulated experience, with special attention to Descartes (genius malignus) and Putnam (brains in a vat), a distinction is made between weak and strong VR, analogous to the distinction made by Searle between weak and strong AI. Expanding on an argument developed by Edward Reed (The Necessity of Experience, 1996) , the paper traces the influence of strong VR in both scientific and everyday experience, and argues that this influence should be strongly resisted.

Phenomenal consciousness. Epiphenomenalism, naturalism, and perceptual plasticity. In: E. Myin, ed., Approaching Consciousness. Special issue of Communication and Cognition 31, 1998, pp. 21-56.
Abstract Theories of phenomenal consciousness generally suffer from an oscillation between epiphenomenalism and naturalism (or eliminativism and realism). Epihenomenalism must be rejected for making the link between consciousness and perception too weak. Naturalism must be rejected for making it too strong, committing the naturalistic fallacy criticized by Wilfrid Sellars. Using the notion of perceptual plasticity, this paper explores the possibility of escaping from the oscillation, finding a place for phenomenal consciousness in the natural order of things.

Abstract Reply to Filip Buekens (ANTW 87, 1995, pp. 294-299), with special attention to the difference between internalist and externalist approaches to mental content on the one hand, and on the other hand the relational alternative developed in Sleutels 1994.

Real knowledge. The problem of content in neural epistemics. (Proefschrift KU Nijmegen; promotor: prof. dr. A.A. Derksen). Nijmegen, 1994. 320 pp., ISBN 9090073736. Recensie: F. Buekens, ANTW 87, 1995, pp. 294-299.
Abstract Extensive discussion of the two main controversies in psychosemantics, namely, that between computationalist and connectionist approaches to mental representation, and that between internalist and externalist accounts of content. As a radical alternative the book proposes a transcendental framework for neural epistemics. Moreover, it argues that both internalism and externalism rest on a category mistake in trying to reduce a relational notion to either one its relata. As an alternative, a relational aproach to mental content is sketched. Review: F. Buekens, ANTW 87, 1995, pp. 294-299.
