"Since the problem of consciousness is such a central one, and since consciousness appears so mysterious, one might have expected that psychologists and neuroscientists would now direct major efforts toward understanding it. This, however, is far from being the case. The majority of modern psychologists omit any mention of the problem, although much of what they study enters into consciousness. Most modern neuroscientists ignore it. ...Not only because of experimental difficulties but also because they considered the problem both too subjective and too "philosophical," and thus not easily amenable to experimental study."
