In Defence of Chalmers: A Comment on Korf

In “Qualia in a Contemporary Neurobiological Perspective”, Korf tackles the perennial issue of qualia in the philosophy of mind. His discussion is partly a response to Chalmers’ hard problem, which, as evidenced by other recent discussions in Dialogues, remains fresh after nearly two decades. Korf highlights the importance of regarding each brain as a particular shaped by unique contingencies and suggests how neurobiological research might proceed in light of this. However, I argue that his discussion does not address what is at the core of Chalmers’ hard problem, and so fails to bridge the gap between neurobiological processes and qualia

Is consciousness necessary to high-level control systems?

Building on Bringsjord's (1992, 1994) and Searle's (1992) work, I take it for granted that computational systems cannot be conscious. In order to discuss the possibility that they might be able to pass refined versions of the Turing Test, I consider three possible relationships between consciousness and control systems in human-level adaptive agents

Making Sense of Biological Naturalism

Searle’s theory of Biological Naturalism has been largely ignored in the philosophical literature and Searle’s commentators are confused by his seemingly contradictory views. In this dissertation I attempt to make sense of Biological Naturalism. In chapter 2 I will ascertain which concerns prevent Searle’s readers from understanding his position. The remaining chapters aim to dissolve the tensions and dispel any confusion. Chapter 3 considers Searle’s notion of first-person ontology, finding that it expresses a belief that experiences are essentially subjective and qualitative. In chapter 4 I consider the notions of levels of description, causal reduction and what Searle means by causation and realisation. Chapter 5 turns to the question of how to categorise Searle’s position. Many of his critics charge him with being a property dualist. By highlighting the difference between the meaning of irreducibility intended by the property dualist and Searle I show that there is sufficient difference in their use of the term so as to reject an interpretation of Biological Naturalism as a form of property dualism. Chapter 6 is where I turn to the other end of the physicalism/dualism spectrum and assess whether Searle should be seen as holding a form of identity theory. I first argue for a neutral form of identity that I call real identity, which does not include the inherent reductive privileging of standard identity. I then argue that Searle should be seen as advocating a form of real identity theory; a form of token identity theory which does not privilege the physical over the mental. In chapter 7 I return to the main barriers to making sense of Biological Naturalism which I identified in chapter 2 and lay out my response to each. I conclude with a coherent interpretation of Searle’s position

The Mental Database

This article uses database, evolution and physics considerations to suggest how the mind stores and processes its data. Its innovations in its approach lie in:- A) The comparison between the capabilities of the mind to those of a modern relational database while conserving phenomenality. The strong functional similarity of the two systems leads to the conclusion that the mind may be profitably described as being a mental database. The need for material/mental bridging and addressing indexes is discussed. B) The consideration of what neural correlates of consciousness (NCC) between sensorimotor data and instrumented observation one can hope to obtain using current biophysics. It is deduced that what is seen using the various brain scanning methods reflects only that part of current activity transactions (e.g. visualizing) which update and interrogate the mind, but not the contents of the integrated mental database which constitutes the mind itself. This approach yields reasons why there is much neural activity in an area to which a conscious function is ascribed (e.g. the amygdala is associated with fear), yet there is no visible part of its activity which can be clearly identified as phenomenal. The concept is then situated in a Penrosian expanded physical environment, requiring evolutionary continuity, modularity and phenomenality.Several novel Darwinian advantages arising from the approach are described

Emergentism as an option in the philosophy of religion: between materialist atheism and pantheism

Among worldviews, in addition to the options of materialist atheism, pantheism and personal theism, there exists a fourth, “local emergentism”. It holds that there are no gods, nor does the universe overall have divine aspects or any purpose. But locally, in our region of space and time, the properties of matter have given rise to entities which are completely different from matter in kind and to a degree god-like: consciousnesses with rational powers and intrinsic worth. The emergentist option is compared with the standard alternatives and the arguments for and against it are laid out. It is argued that, among options in the philosophy of religion, it involves the minimal reworking of the manifest image of common sense. Hence it deserves a place at the table in arguments as to the overall nature of the universe

Criticism, Contact With Reality and Truth

Partly in reply to D. Cannon’s critique of his analytical reconstruction (1988) of Polanyi’s post-critical theory of tacit knowledge, the author argues that there are good reasons for not appropriating Polanyi’s programme of self-identication and the confessional rhetoric which may be derived from it. Arguing that “post-critical” should not be identified with an uncritical dogmatism, the author attempts to show that the theory of tacit knowing had best be elaborated by employing certain insights of John Searle. The notion of “contact with reality” is explicated in order to highlight the Polanyian criteria of truth.
