When we find a thinker reflecting or echoing an apparently erroneous, narrow, or even illogical thought that was popular or authoritative in his time, we must never rule out the possibility that what we have discovered is not the limit of his vision but only an example of his deliberate rhetorical accommodation to reigning prejudice which he does not share but thinks it best not to expose.

Considering the enormous range of human knowledge, from intimate personal knowledge of specific individuals to the complexities of organizations and the subtleties of feelings, it is remarkable that one speck in this firmament should be the sole determinant of whether someone is considered knowledgeable or ignorant in general. Yet it is a fact of life that an unlettered person is considered ignorant, however much he may know about nature and man, and a Ph.D. is never considered ignorant, however barren his mind might be outside his narrow specialty and however little he grasps about human feeling or social complexities.

Physicists have determined that even the most solid and heavy mass of matter we see is mostly empty space. But at the submicroscopic level, specks of matter scattered through a vast emptiness have such incredible density and weight, and are linked to one another by such powerful forces, that together they produce all the properties of concrete, cast iron and solid rock. In much the same way, specks of knowledge are scattered through a vast emptiness of ignorance, and everything depends upon how solid the individual specks of knowledge are, and on how powerfully linked and coordinated they are with one another.

Ideas, as the raw material from which knowledge is produced, exist in superabundance, but that makes the production of knowledge more difficult rather than easier. Many ideas- probably most- will have to be discarded somewhere in the process of producing authenticated knowledge. Authentication is as important as the raw information itself, and the manner and speed of the authentication process can be crucial...

Ideas are everywhere, but knowledge is rare.

We should listen first and foremost to our own experience...We should stop looking for saviors... Society has not existed for thousands of years because it had a succession of saviors. It's existed because it has institutions and processes through which people can realize their own goals.
