“But my brain, which is also I, your brain and the thoughts within it, as well as the house across the street, are all forms of an inextricably interwoven process called the real world. Conscious or unconscious of it as I may be, it is all I in the sense that the sun, the air, and human society are just as vital to me as my brain or my lungs. If, then, this brain is my brain—unaware of it as I am—the sun is my sun, the air my air, and society my society.”
