You don’t appear to be reading with the intent to comprehend what’s being said. Try again, but without injecting your prior assumptions about what’s being said and without beginning to formulate a response before you’ve understood. What I’m saying is that there’s no known evolutionary reason all of these experiences should be witnessed by a subject. Thoughts, feelings, sensory impressions could all theoretically happen without a subject witnessing them, which is the thing that consciousness is. Please either re-read what I just wrote until you really feel like communication is happening here or ask questions if you don’t understand my meaning.
