A Quote by Charles Darwin

It is certain that there may be extraordinary mental activity with an extremely small absolute mass of nervous matter: thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin's head. Under this point of view, the brain of an ant is one of the most marvelous atoms of matter in the world, perhaps more so than the brain of a man.
It seems to me immensely unlikely that mind is a mere by-product of matter. For if my mental processes are determined wholly by the motions of atoms in my brain I have no reason to suppose that my beliefs are true. They may be sound chemically, but that does not make them sound logically. And hence I have no reason for supposing my brain to be composed of atoms.
You are not barred from attaining greatness by heredity. No matter who or what your ancestors may have been or how unlearned or lowly their station, the upward way is open for you. There is no such thing as inheriting a fixed mental position; no matter how small the mental capital we receive from our parents, it may be increased; no man is incapable of growth.
We need only view a Dissection of that large Mass, the Brain, to have ground to bewail our Ignorance...We admire...the Fibres of every Muscle, and ought still more to admire their disposition in the Brain, where an infinite number of them contained in a very small Space, do each execute their particular Offices without confusion or disorder.
In proportion to the mental energy he spent, the man who creates a new invention receives but a small percentage of his value in terms of material payment, no matter what fortune he makes, no matter what millions he earns. But the man who works as a janitor in the factory producing that invention, receives an enormous payment in proportion to the mental effort that his job requires of him. And the same is true of all men between, on all levels of ambition and ability.
Nervous exhaustion from mental overwork is most often due to neglect of this rule and the brain worker should limit his regular day's work to a reasonable number of hours per day and those when the brain is at its best.
I've always been interested in the paranormal, but 'Gray Matter' is a more subtle, mature expression of that - looking at the powers of the brain and more delicate evidence of the extraordinary.
[T]he more clamour we make about 'the women's point of view', the more we rub it into people that the women's point of view is different, and frankly I do not think it is -- at least in my job. The line I always want to take is, that there is the 'point of view' of the reasonably enlightened human brain, and that this is the aspect of the matter which I am best fitted to uphold.
We are part of nature, a product of a long evolutionary journey. To some degree, we carry the ancient oceans in our blood. … Our brains and nervous systems did not suddenly spring into existence without long antecedents in natural history. That which we most prize as integral to our humanity - our extraordinary capacity to think on complex conceptual levels - can be traced back to the nerve network of primitive invertebrates, the ganglia of a mollusk, the spinal cord of a fish, the brain of an amphibian, and the cerebral cortex of a primate.
We will move from looking at correlations between brain activity and behaviour to studying how the brain causes mental states and behaviour.
We now know that the way to help a child develop optimally is to help create connections in her brain—her whole brain—that develop skills that lead to better relationships, better mental health, and more meaningful lives. You could call it brain sculpting, or brain nourishing, or brain building. Whatever phrase you prefer, the point is crucial, and thrilling: as a result of the words we use and the actions we take, children’s brains will actually change, and be built, as they undergo new experiences.
More than anything, the weed really helped with my mental state, because marijuana works on the brain. And if anything, it soothes the brain.
Successful investment may become substantially a matter of techniques and criteria that are learnable, rather than the product of unique and incommunicable mental powers.
Of all the people expressing their mental vacuity, none has a better excuse for an empty head than the newspaperman: If he pauses to restock his brain, he invites onrushing deadlines to trample him flat. Broadcasting the contents of empty minds is what most of us do most of the time, and nobody more relentlessly than I.
From the physical point of view, a man is nothing more than a system of cells, or from the mental point of view, than a system of representations; in either case, he differs only in degree from animals.
Most psychiatrists assume that mental illnesses such as depression are caused by chemical imbalances in the brain, which can be treated by drugs. But most psychotherapy doesn't address the social causation of mental illness either.
The world is large, very large. My head is small, quite small. There is no way I can put the world in my head. Nevertheless, I have been trying to elaborate some kind of representation.
