Don’t be sorry, Yppop: it’s not an interruption but an irrefutable conclusion! Thomas Nagel’s What Is It Like to Be a Bat? online article develops it in detail.Candide, Tony,
Forgive me for imposing on your polite discussion to make a comment about the nature of the mental processes that I assume CW believes are due solely to the material brain, a belief with which TR surely disagrees.
Here is a synopsis of my interpretation of Gerald Edelman’s (a noble prize winning biologist), theory of consciousness: It is called the Theory of Neuronal Group Selection. Skipping over the neurological jargon, his main line of argument goes something like this: neuronal circuits are developed and formed with experience to construct the dynamic reentrant core. The dynamic core, a complex array of neuronal circuits that feeds itself (reentrant processing), converts signals from the world and the brain into a “phenomenal transform” that entails an n-dimensional qualia space. Consciousness as a property of the dynamic core is a reflection of the capacity to make refined discriminations in the multidimensional qualia space. In other words consciousness is defined using the words: property, reflection, capacity, discriminations, and finally qualia space. Most materialists simply explain qualia with the catchall phrase “emergent property”. Even though he is an avowed materialist, Edelman seems to want to explicatively implant qualia as far away from the neuronal circuits of the brain as his theory will allow. Qualia are all those things we experience that are both subjectively real and immaterial such as (1) sensations (color, sweetness, wetness, pain, stench, etc.); (2) feelings (well-being, happiness, pleasure, pride, etc.; (3) emotions (joy, despair, anger, ennui, hope, etc.; (4) transcendentals (beauty, truth, justice, awe, peace, etc.).; and (5) (our will, and the “I” that is “you”).
Candide, I assume that it is this qualia space that you are denying is real and immaterial, that there is no “other” form of reality beyond that which can be experienced materially (or through energy). Certainly we cannot experience qualia without the functioning neuronal circuits of the brain; the brain is necessary. However if the qualia space is not material, what is it? If it is spatial, it must be a special form of space that can “store” redness, sweetness, images of other people, etc.
I would argue that the brain, as Edelman states it, “entails” qualia; i.e., the brain causes the mind to “experience” qualia however because qualia are immaterial, the material brain cannot be their “repository”. The mind, part of which is the brain, necessarily must also be composed of an immaterial substance. Without qualia, without the spiritual substance in which qualia reside, we would be zombies constructed merely from quarks and electrons
Sorry for the interruption,
