What is the substance of the experienced?
So, chemical and electrical impulses are the substance of sensation, correct? So, what is experiencing them? They are being processed in the brain, but we are not brains. Or are we? What is the material of the experienced? The scientific chemical reaction, how does it result in something which can only be experienced and not otherwise quanitified? Or can everything be quantified? How do we combine the experienced and the experiencer, can we quantify both at the same time? Let's say that the experiencer is a chemical that meets with another chemical, the experience, they meet and we experience something. What is the distinction between the "experiencer" chemical and the "experienced" chemical? What decides that that particular combination of chemicals is experiencable when experiences can range to almost anything?
