Brain, n. An apparatus with which we think that we think... In our civilization, and under our republican form of government, intelligence is so highly honored that it is rewarded by exemption from the cares of office.

Why, anybody can have a brain. That's a very mediocre commodity. Every pusillanimous creature that crawls on the Earth or slinks through slimy seas has a brain. Back where I come from, we have universities, seats of great learning, where men go to become great thinkers. And when they come out, they think deep thoughts and with no more brains than you have. But they have one thing you haven't got: a diploma.

Which statement seems more true: (1) I have a brain. (2) I am a brain.

The human brain is a complex organ with the wonderful power of enabling man to find reasons for continuing to believe whatever it is that he wants to believe.

If you only had brain in your head you would be as good as man as any of them, and a better man than some of them. Brains are the only things worth having in this world, no matter whether one is a crow or a man.

Our intelligence is the prolongation of our senses. Before we speculate we must live, and life demands that we make use of matter, either with our organs, which are natural tools, or with tools, properly so-called, which are artificial organs. Long before there was a philosophy and a science, the role of the intelligence was already that of manufacturing instruments and guiding the action of our body on surrounding bodies. Science has pushed this labor of the intelligence much further, but has not changed its direction.

Intelligence is no human sideshow but an evolutionary main event. The power to foresee, to call upon the past in terms of the future, to evaluate, to imagine solutions, is a power flowing from old time springs. The human mind may be denied the policeman's privilege of arresting this instinct or that. It may sit as no more than a moderator in the eternal instinctual debate. But it is a moderator with unlimited investigative powers.

There is no doubt that the human mind is fundamentally incapable of solving these formidable problems (the origin of life, nature of matter, origin of movement, and appearance of consciousness). Our brain is an organ of action that is directed toward practical tasks; it does not appear to have been built for discovering the ultimate causes of things, but rather for determining their immediate causes and invariant relationships.

Man knows and his capacity to know depends on his biological integrity; furthermore, he knows that he knows. As a basic psychological and, hence, biological function cognition guides his handling of the universe and knowledge gives certainty to his acts; objective knowledge seems possible and through objective knowledge the universe appears systematic and predictable.

I don’t know...but then, if God had intended Man to think, He would have given him brains, I suppose.

In addition to that sentience, which the insect or animal has, the human being is endowed with intellect. Intellect is what is cognized, which the animal need not do. So it is this power of the intellect to discriminate and interpret what is cognized that gives the individual being a sense of individuality and makes him consider himself something special in this manifestation. What is more, he goes to the extent of believing that the entire manifestation has been created for his benefit! So, all the time he is thinking, In what way can I benefit by exploiting nature?" And the extent to which the human being has 'benefited' himself, we can all see.

A human is a complicated organic/electrical system, which is immersed in a culture. Try raising a monkey like a human, it won't work, you need the human's certain brain characteristics (including self-reflection) in order to create a truly intelligent creature. The brain processes inputs and perception in very particular ways, and I think until we understand the underlying processes better, there is no way to really simulate it in software. Computers will continue to be good at simplistic analysis, and raw processing power, but the subtlety of emotions is something intrinsic to the human organism and culture.
