Ideals are very often formed in the effort to escape from the hard task of dealing with facts, which is the function of science and art. There is no process by which to reach an ideal. There are no tests by which to verify it. It is therefore impossible to frame a proposition about an ideal which can be proved or disproved. It follows that the use of ideals is to be strictly limited to proper cases, and that the attempt to use ideals in social discussion does not deserve serious consideration.

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.

At present, obviously, the metaphor is the digital computer.

It may indeed prove to be far the most difficult and not the least important task for human reason rationally to comprehend its own limitations. It is essential for the growth of reason that as individuals we should bow to forces and obey principles which we cannot hope fully to understand, yet on which the advance and even the preservation of civilization depend.

Knowledge can be enormously costly, and is often scattered in widely uneven fragments, too small to be individually usable in decision making. The communication and coordination of these scattered fragments of knowledge is one of the basic problems- perhaps the basic problem- of any society.
