The redness of the rose is not perceived by the eye, as the eye can be perfectly fine yet the patient will not see the red rose if his optic nerve (the nerve from the eye to the brain) is cut. Therefore, the redness of the rose is perceived not by the eye, but by the brain (or so it is believed by neuroscientists). Somewhere in the brain, there arises the idea that a red rose is being perceived. The neuroscientist observes the brain of the patient and records his observations. But most unfortunately for the neuroscientist, no observation of the brain will reveal a red rose inside the brain. Third-Person (Neuroscientist's) Viewpoint: "There is a material entity (brain) with billions of grey neurons that are excited by electrical impulses, and affected by chemical substances such as drugs and proteins." First-Person (Patient's) Viewpoint: "I see a RED ROSE." |||||||||||||||||||||||||||||||| Namaste Jayanarayananji, Very clear exposition of the current impasse in the field of consciousness studies. Inevitably the sense data theory derealises the object reducing it to events in the brain which may or may not have an object to which they refer. Thus in the extreme case the world drops away and becomes a fond illusion. In short the sense data theory cannot be the basis of any valid means of knowledge because there could be no way of telling the difference between error and true perception. So we may ask: what is it that has been 'transmitted' from rose as object that makes a rose as percept a valid representation. Various philosophers of the realist persuasion have offered solutions which have a family resemblance and which are based on an intuition in the sense of immediate perception of a truth e.g. the whole is greater than a part, and also an intuition in the sense of a species of divination. The immediate intuition is that the object is a given pre-theoretic reality that we have to deal with. The other form of intuition is the experience of the object shining in us, in its reality as it is. This can only happen when the immaterial form of the object which is the basis of its reality i.e. its upadhi, can also shine within our consciousness. Because it shines in our consciousness we assume the commonality of the substratum that allows this to happen. This substratum must be consciousness itself. In effect what this means is that the brain is not conscious but that the brain is consciousness or is nondual with consciousness. Another way this is sometimes put is that consciousnesspervades material reality seamlessly. The section on Perception in Vedanta Paribhasa (pub Advaita Ashrama) is a difficult but rewarding study, Best Wishes, Michael Quote Link to comment Share on other sites More sharing options...
