We went over this last year. Here's a URL and an excerpt.
Dr. Terrence Sejnowski, director of the Computational Neurobiology
Laboratory at the Salk Institute, agrees that the properties of the brain
can likely be duplicated in artificial devices, although he regards

"My own suspicion is that words like 'consciousness' and 'qualia' will go
the way of words like 'phlogiston' and 'vitalism.'"
"The Ghost in the machine is dead."
--New Yawk Tymes
consciousness, phlogiston, philosophy, vitalism, mind, free will, qualia
