There is no Matter – 7
In other words: matter testifies of itself, “I am matter;” but unless matter is mind, it cannot talk or testify; and if it is mind, it is certainly not the Mind of Christ, not the Mind that is identical with Truth.
Brain, thus assuming to testify, is only matter within the skull, and is believed to be mind only through error and delusion. Examine that form of matter called brains, and you find no mind therein. Hence the logical sequence, that there is in reality neither matter nor mortal mind, but that the self-testimony of the physical senses is false. (Eddy, Mary Baker, Unity of Good, p.33:10-20)
