There is no coherent knowledge , i.e. no uniform comprehensive account of the world and the events in it. There is no comprehensive truth that goes beyond an enumeration of details, but there are many pieces of information , obtained in different ways from different sources and collected for the benefit of the curious. The best way of presenting such knowledge is the list - and the oldest scientific works were indeed lists of facts, parts, coincidences, problems in several specialized domains.

A scientist, an artist, a citizen is not like a child who needs papa methodology and mama rationality to give him security and direction, he can take care of himself, for he is the inventor not only of laws, theories, pictures, plays, forms of music, ways of dealing with his fellow man, institutions, but also entire world view, he is the inventor of entire forms of like.

Unanimity of opinion may be fitting for a church, for the frightened or greedy victims of some (ancient, or modern) myth, or for the weak and willing followers of some tyrant. Variety of opinion is necessary for objective knowledge. And a method that encourages variety is also the only method that is comparable with a humanitarian outlook.

Language became a colorless and as indistinct as the business suit which is now worm by everyone, by the scholar, by the businessman, by the professional killer. Being accustomed to a dry and dreary norm and sees in it an obvious sign of arrogance and aggression; viewing authority with almost religious awe he gets into a frenzy when he sees someone pluck the beard of his favorite prophet.

The world we inhabit is abundant beyond our wildest imagination. There are trees, dreams, sunrises; there are thunderstorms, shadows, rivers; there are wars, flea bites, love affairs; there are the lives of people, Gods, entire galaxies. The simplest human action varies from one person and occasion to the next-how else would we recognize our friends only from their gait, posture, voice, and divine their changing moods? Only a tiny fraction of this abundance affects our minds. This is a blessing, not a drawback.

Science is only ‘one’ of the many instruments people invented to cope with their surroundings. It is not the only one, it is not infallible and it has become too powerful, too pushy and too dangerous to be left on its own.

The idea of a method that contains firm, unchanging, and absolutely binding principles for conducting the business of science meets considerable difficulty when confronted with the results of historical research. We find, then, that there is not a single rule, however plausible, and however firmly grounded in epistemology, that is not violated at some time or another.
