Not only are facts and theories in constant disharmony, they are never as neatly separated as everyone makes them out to be. - Paul Feyerabend

Experts often arrive at different results, both in fundamental matters, and in application Who does not know of at least one case in his family where one doctor recommends a certain operation, another argues against it, while a third suggests an entirely different procedure? Who has not read of the debates about nuclear safety, the of the economy, the effects of pesticides, aerosol sprays, the efficiency of methods of education, the influence of race on intelligence? Two, three, five and even more views arise in such debates, and scientific supporters can be found for all of them. Occasionally one almost feels inclined to say: as many scientists, as many opinions. There are of course areas in which scientists agree- but this cannot raise our confidence. Unanimity is often the result of a political decision: dissenters are suppressed, or remain silent to preserve the reputation of science as a source of trustworthy and almost infallible knowledge. On other occasions, unanimity is the result of shared prejudices: positions are taken without detail examination of the matter under review and are infused with the same authority that proceeds from detailed research.

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.

People have different professions, different points of view. They are like observers looking at the world through the narrow windows of an otherwise closed structure. Occasionally they assemble at the center and discuss what they have seen; then one observer will talk about a beautiful landscape with red trees, a red sky, and a red lake in the middle; the next one about an infinite blue plane without articulation; and the third about an impressive, five-floor-high building; they will quarrel. The observer on top of the structure (me) can only laugh at their quarrels-but for them the quarrels will be real and he (the observer on top) will be an unworldly dreamer. Real life... is exactly like that. Every person has his own well-defined opinions, which color the section of the world he perceives. And when people come together, when they try to discover the nature of the whole which they belong, they are bound to talk past each other; they will understand neither themselves nor their companions.
