The Ego Tunnel: The Science of the Mind and the Myth of the Self (Metzinger, 2009)
Start with six questions.
- One-World Problem, or the unity of consciousness;
- Now Problem, or the appearance of a lived moment;
- Reality Problem, or why you were born as a naive realist;
- Ineffability Problem, or what we will never be able to talk about;
- Evolution Problem, or the question of what consciousness was good for;
- Who Problem, or the issue of what is the entity that has conscious experience.
One-World Problem
photocopy all existing encyclopedia articles on the topic I could find and track down the historical references. I wanted to know whether in the long history of Western philosophy there was a common philosophical insight running like a thread through humanity’s perennial endeavor to understand the conscious mind. To my surprise, I found two such essential insights.
The first is that consciousness is a higher-order form of knowledge accompanying thoughts and other mental states... in an important sense, consciousness is knowing that you know while you know.
This, Metzinger skips over.
The second important insight seems to be the notion of integration: Consciousness is what binds things together into a comprehensive, simultaneous whole. If we have this whole, then a world appears to us. If the information flow from your sensory organs is unified, you experience the world. If your senses come apart, you lose consciousness.
Why do we see one world only? Why can't we consciously multitask? Why can't we consciously multi-see, multi-feel, multi-think? (Certainly, we can multitask unconsciously, as in, talking while bicycling while balancing the groceries in one hand, but only one task might occupy the consciousness at one time.)
