Both spiritual and materialistic ways of looking at life are created in the thinking mind. Advaita-Vedanta, Marxism, Catholicism, Mahayana Buddhism and Empirical Positivism, delusions, explanations, great theories, political opinions, idiotic ideas, clever ideas, silly jokes, they are all creations of the thinking mind.
If the speech center of the brain is damaged by a hemorrhage, you’re no longer able to create explanations, theories and opinions. Hallucinations, dreams, daydreams, reveries and visions emanate from other parts of the brain. Anger and fear are created in the reptilian brain and love is created in the limbic system. So what? Why bother?
Where is the observing self or the sense of I located? It’s apparently not created in the speech center. Someone with a damaged speech center because of a brain hemorrhage will still wake up in the morning and feel that they are. To me it doesn’t matter. To me it’s not even particularly important if my sense of I is located in my brain or somewhere outside my body. I think that there are many much more important issues to be considered, for example: Where did I put my bike key? What shall I cook for supper? Should I drop my resentment towards Ms X though she is still full of shit? How shall I live my life?
