7. Existence / C. Structure of Existence / 2. Reduction

3990	The whole truth supervenes on the physical truth [Lewis]
	Full Idea: The whole truth supervenes on the physical truth.
	From: David Lewis (Lewis: reduction of mind (on himself) [1994], p.412)
	A reaction: This seems to me the central truth about brains, and we should not be lured into abandoning it. We should not, however, exclude the possibility that there is a non-physical reality.

7. Existence / C. Structure of Existence / 5. Supervenience / b. Types of supervenience

3991	Where pixels make up a picture, supervenience is reduction [Lewis]
	Full Idea: In the case of millions of pixels making up a picture on a computer screen, the supervenience is reduction.
	From: David Lewis (Lewis: reduction of mind (on himself) [1994], p.414)
	A reaction: Since 'supervenience' seems a suspect relationship about which no one is clear, this is a point very much worth making.
