Summary:  This workshop will begin with an explanation of the general problem of consciousness and various senses of the term ‘conscious.’  Various traditional philosophical theories of consciousness are then introduced largely under the umbrella of the metaphysical distinction between dualism and materialism (or, more broadly, physicalism).  For example, we will critically examine such dualist views as substance dualism, property dualism, and epiphenomenalism.  On the physicalist side, we will critically examine identity theory, eliminative materialism, and functionalism.  We will also discuss global workspace theory, multiple drafts theory, attended intermediate level theory, and sensorimotor theory, which are also broadly functionalist-physicalist theories themselves.  Nondualist, but non-standard, physicalist views are also addressed, including panpsychism, emergentism, quantum approaches (such as Orch OR), and dual aspect theory.  Finally, various versions of representationalism are presented, such as first-order representationalism (FOR), higher-order thought (HOT) theory, and self-representationalism.  Some questions to be addressed are: What are the main arguments for, and objections to, the major physicalist and dualist views?  What is the main reason for exploring alternatives such as panpsychism and quantum theories?  What is the difference between a first-order representation and a higher-order (or meta-) representation?  What makes a mental state a conscious mental state?  Can any of the physicalist theories offer a viable reductionist account of consciousness?  Are any of them able to solve the “hard problem” of consciousness?  How does holding a dualist position help?  Strengths and weaknesses of each theory are emphasized.  Authors to be discussed include R. Descartes, G.W. Leibniz, Bertrand Russell, David Chalmers, David Rosenthal, William Lycan, Michael Tye, William Robinson, Patricia and Paul Churchland, Bernie Baars, Frank Jackson, Thomas Nagel, Ned Block, Daniel Dennett, Jesse Prinz, Kevin O’Regan, Colin McGinn, Hilary Putnam, Galen Strawson, R. Penrose & S. Hameroff, Uriah Kriegel, and others.
