Unity of Experience. There is no unified "self" that generates internally consistent and seamlessly coherent beliefs devoid of conflict. Instead, we are a collection of distinct but interacting modules -- or neural networks -- that are often at odds with one another. According to the evolutionary psychologist Robert Kurzban, the brain evolved as a modular, multitasking, problem-solving organ -- a Swiss Army knife or practical tools, in the old metaphor, or an app-loaded iPhone, in Kurzban's upgrade. The module that leads us to crave sweet and fatty foods in the short term, for example, is in conflict with the module that monitors our body image and health in the long term. The module of cooperation is in conflict with the module fore for truth telling with the module for lying. Of course, because the brain does not sense itself opeating, we are blissfully unaware of all these networks running largely independently, so it feels as though there is unity of self. ~ Page 125 (Excerpt: "Heaven on Earth" ~ Author - Michael Shermer

. . . . Here is a truth that neuropsychology appears entirely to overlook: 'minds are not brains'. Please note that I do not intend anything non-materialistic by this remark; there are only brains, and minds are not some ethereal spiritual stuff a la Descartes. What I mean is that minds are the result of the social interaction between brains. As essentially social animals, humans are nodes in complex networks from which their mental lives derive most of their content. A single mind is, accordingly, the result of interaction between many brains, and this is not something that shows up on an fMRI scan. The historical, social, educational and philosophical dimensions of the constitution of individual character and sensibility are vastly more than the electrochemistry of brain matter by itself. Neuroscience is an exciting and fascinating endeavour which is teaching us a great deal about brains and the way some aspects of mind are instantiated in them, but by definition it cannot teach us everything, of what we would like to know about minds and mental life. ~ Page 121 Excerpt: :The Challenge of Things" - author - A.C.Grayling

The brain is the body -- part one

We tend to see the brain and body as separate things. While in previous epochs the bears was the center of one being, or at least on an equal footing with the mind is operating the rest of us, like a man inside a bulldozer.

The whole idea of “mental health” as something separate to physical health can be misleading, in some ways. So much of what you feel with anxiety and depression happens elsewhere. The heart palpitations, the aching limbs, the sweaty palms, the tingling sensations that often accompany anxiety, for instance. Or the aching limbs and the total-body fatigue that sometimes becomes part of depression. ~ Page 78 Excerpt "Reasons to Stay Alive" Author Matt Haig

Helmholtz was mentor to fellow materialist physician and physicist Ernst Brucke. en.wikipedia.org/wiki/Ernst_Wilhelm_von_Br%C3%BCcke Both were dedicated to the idea that elements that made up the mind are physical, and all the causal relations between the elements are governed by the same mechanical principles that govern physics and chemistry. No vital spirits, no mysticism, no ghosts. The mind and the body are one. Brucke went on to become a professor of physiology at the University of Vienna, where he would have a great deal of influence on one of his students: Sigmund Freud. Can you imagine the intense excitement of the intellectual and scientific atmosphers? No more spooks in the system. It was just the brain, made up of parts, many of which worked outside conscious awareness, all driven ny chemistry and physics. ~ page 47 Excerpt: "The Consciousness Instinct" ' Michael Gazzaniga, Author
