A Quote by John Searle
You can't *discover* that the brain is a digital computer. You can only *interpret* the brain as a digital computer.

Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard...Sherrington, the great British neuroscientist, thought the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electromagnetic systems. Leibniz compared it to a mill...At present, obviously, the metaphor is the digital computer.
When developers of digital technologies design a program that requires you to interact with a computer as if it were a person, they ask you to accept in some corner of your brain that you might also be conceived of as a program.
I was the first to advocate the Web. But I am very troubled by this thing that every kid must have a laptop computer. The kids are totally in the computer age. There's a whole new brain operation that's being moulded by the computer.
It's not even known how many kinds of cells there are in the brain. If you were looking for a periodic table of the brain, there is no such thing. I really like to think of the brain as a computer.
Autism is a neurological disorder. It's not caused by bad parenting. It's caused by, you know, abnormal development in the brain. The emotional circuits in the brain are abnormal. And there also are differences in the white matter, which is the brain's computer cables that hook up the different brain departments.
I think the brain is essentially a computer and consciousness is like a computer program. It will cease to run when the computer is turned off. Theoretically, it could be re-created on a neural network, but that would be very difficult, as it would require all one's memories.
Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped onto the other (the computer).
But if the brain is not like a computer, then what is it like? What kind of model can we form in regard to its functioning? I believe there's only one answer to that question, and perhaps it will disturb you: there is no model of the brain, nor will there ever be. That's because the brain, as the constructor of all models, transcends all models. The brain's uniqueness stems from the fact that nowhere in the known universe is there anything even remotely resembling it.
It's funny, because I'm so associated with digital art and computer art, and yet I spend so little time in front of the computer.
A computer cannot manufacture new information. That's the difference between our brain and a computer.
The essential characteristic of digital information is that it can be manipulated easily and very rapidly by computer... Computational tools for transforming, combining, altering, and analyzing images are as essential to the digital artist as brushes and pigments to a painter.
In terms of the brain, you can in a crude way think of the human brain as a computer.
The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.
The most complex object in the known universe: brain, only uses 20 watts of power. It would require a nuclear power plant to energize a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that's a compliment.
A meticulous virtual copy of the human brain would enable basic research on brain cells and circuits or computer-based drug trials.
Many cognitive psychologists see the brain as a computer. But every single brain is absolutely individual, both in its development and in the way it encounters the world.
