In a war a totalitarian state has a free hand. - Paul Feyerabend

Experts have a vested interest in their own playpens, and so they will quite naturally argue that 'education' is impossible without them (can you imagine an Oxford philosopher, or an elementary particle physicist arguing himself out of good money?)

The existence of antagonistic "conspiracies" was recognized by the defenders of religious and political views. Iconoclasts knew that images might distort the basic message of their creed (which consisted of words and resided in Holy Books). Church architecture and church music were adapted to the needs of the Holy Faith. Alternative styles were either fought or made part of religious PR. I conclude that our 'field of experience' is molded, overlaid, and 'conspired' against not just by language, but by numerous other patterns and institutions, many of them in mutual conflict. An inference from a style, a particular linguistic apparatus, or, more recently, from scientific beliefs, to a cosmology, corresponding ways of life and an all-embracing "spirit of the age therefore needs special support; it cannot be made as a matter of course.

Progress was often achieved by a "criticism from the past"… After Aristotle and Ptolemy, the idea that the earth moves - that strange, ancient, and "entirely ridiculous", Pythagorean view was thrown on the rubbish heap of history, only to be revived by Copernicus and to be forged by him into a weapon for the defeat of its defeaters. The Hermetic writings played an important part in this revival, which is still not sufficiently understood, and they were studied with care by the great Newton himself. Such developments are not surprising. No idea is ever examined in all its ramifications and no view is ever given all the chances it deserves. Theories are abandoned and superseded by more fashionable accounts long before they have had an opportunity to show their virtues. Besides, ancient doctrines and "primitive" myths appear strange and nonsensical only because their scientific content is either not known, or is distorted by philologists or anthropologists unfamiliar with the simplest physical, medical or astronomical knowledge.
