7. It is interesting to note how perhaps the foremost theoretical «blind spot» of current philosophy of mind is conscious suffering. Thousands of pages have been written about color qualia and zombies, but almost no theoretical work is devoted to ubiquitous phenomenal states such as physical pain, boredom, or the everyday sadness known as subclinical depression. The same is true of panic, despair, shame, the conscious experience of mortality, and the phenomenology of losing one's dignity. Why are these forms of conscious content generally ignored by the best of today's philosophers of mind? Is it simple careerism («Nobody wants to read too much about suffering, no matter how insightful and important the arguments are»), or are there deeper, evolutionary reasons for this cognitive scotoma? When one examines the ongoing phenomenology of biological systems on our planet, the varieties of conscious suffering are at least as dominant as, say, the phenomenology of color vision or the capacity for conscious thought. The ability to consciously see color appeared only very recently, and the ability to consciously think abstract thoughts of a complex and ordered form arose only with the advent of human beings. Pain, panic, jealousy, despair, and the fear of dying, however, appeared millions of years earlier and in a much greater number of species.
CHAPTER 8
1. Our belief in invisible persons may have different roots, possibly including so-called hyperactive agent-detection devices (see D. Barrett, «Exploring the Natural Foundations of Religion,» Trends Cog. Sci. 4:29–34, 2000) and ancestor cults: See Daniel C. Dennett, Breaking the Spell: Religion as a Natural Phenomenon (New York: Viking, 2006), esp. 109ff; and Thomas Metzinger, Being No One: The Self-Model Theory of Subjectivity (Cambridge, MA: MIT Press, 2003), 371ff. Also note that out-of-body experiences would almost inevitably have contributed to early humankind's firm belief in the existence of invisible persons and more subtle levels of reality. See T. Metzinger, «Out-of-Body Experiences as the Origin of the Concept of a 'Soul,'» Mind and Matter 3(1):57–84 (2005).

Here are examples of how the patient described her own conscious experience: «I'm falling down in my head, I no longer wish to live, to see anything, hear anything, feel anything.» The authors report that when she was asked why she was crying and if she felt pain, she responded: «No, I'm fed up with life, I've had enough. I don't want to live anymore, I'm disgusted with life. Everything is useless, always feeling worthless, I'm scared in this world.»
When asked why she was sad, she replied: «I'm tired. I want to hide in a corner. I'm crying over myself, of course. I'm hopeless, why am I bothering you.» Note that deep brain stimulation can also have just the opposite effect, namely, relief from serious, treatment-resistant depression. Here is a description:

Clinicians have long observed a deepening of emotionality plus the development of a serious, highly ethical and spiritual demeanor in certain patients with chronic mesial temporal lobe epilepsy. Whether this can count as evidence for a specific kind of «personality syndrome» is still disputed. See O. Devinsky & S. Najjar, «Evidence Against the Existence of a Temporal Lobe Epilepsy Personality Syndrome,» Neurology 53:S13-S25 (1999); D. Blume, «Evidence Supporting the Temporal Lobe Epilepsy Personality Syndrome,» Neurology 53:S9-S12 (1999).

Four years later, after a careful analysis of pros and cons and perhaps surprisingly to many, leading figures in neuroethics are now coming to the conclusion that «We should welcome new methods of improving our brain function. In a world in which human workspans and lifespans are increasing, cognitive enhancement tools-including the pharmacological-will be increasingly useful for improved quality of life and extended work productivity, as well as to stave off normal and pathological accerelated cognitive declines. Safe and effective cognitive enhancers will benefit both the individual and society.» See H. Greely et al., «Towards Responsible Use of Cognitive-Enhancing Drugs by the Healthy,» Nature 456:702–705 (2008).
