We need above all to know about changes; no one wants or needs to be reminded 16 hours a day that his shoes are on.

Can the brain understand the brain? Can it understand the mind? Is it a giant computer, or some other kind of giant machine, or something more?

Those who think 'Science is Measurement' should search Darwin's works for numbers and equations.

The brain is a tissue. It is a complicated, intricately woven tissue, like nothing else we know of in the universe, but it is composed of cells, as any tissue is. They are, to be sure, highly specialized cells, but they function according to the laws that govern any other cells. Their electrical and chemical signals can be detected, recorded and interpreted and their chemicals can be identified; the connections that constitute the brain's woven feltwork can be mapped. In short, the brain can be studied, just as the kidney can.
