So long as authority inspires awe, confusion and absurdity enhance conservative tendencies in society. Firstly, because clear and logical thinking leads to a cumulation of knowledge (of which the progress of the natural sciences provides the best example) and the advance of knowledge sooner or later undermines the traditional order. Confused thinking, on the other hand, leads nowhere in particular and can be indulged indefinitely without producing any impact upon the world.
The natural sciences did not advance in virtue of the universal appeal of rationality. Their theological, classicist and metaphysical opponents were not converted but displaced. All the ancient universities had to be compelled by outside pressure to make room for science; and most nations began to appreciate it only after succumbing to the weapons produced with its aid. To cut a long story short, scientific method has triumphed throughout the world because it bestowed upon those who practised it power over those who did not. Sorcery lost not because of any waning of its intrinsic appeal to the human mind, but because it failed to match the power created by science. But, though abandoned as a tool for controlling nature, incantations remain more effective for manipulating crowds than logical arguments, so that in the conduct of human affairs sorcery continues to be stronger than science.
Laughter is a mental mechanism which enables us to face reality without falling into despondency or delusion. As people who have sunk in apathy seldom bother us by rushing into print, delusion (leaving aside deceit) constitutes the chief obstacle to the progress of our understanding of society, and in this context is usually assumes the form of doctrinairism couched in a mystifying jargon. A sense of humour is the most reliable external indicator of the likelihood of immunity from this folly, and of the ability to appraise social situations realistically.
Sacrifice has always been regarded as the most convincing proof of loyalty; and its most common form involves a foregoing of the use of some organic function, as in the case of celibacy or fasting. Of at least equal significance, however, is a sacrifice of the use of reason - credo quia impossibile - and the more incredible the assertion, the stronger the proof of the devotion manifested by its acceptance. The Catholic theologians are quite explicit about this, and openly say that by affirming what to the human reason appears absurd, a believer proves his love for God. Although they are never so frank about it, the secular sects make similar demands.
[T]he reason why human understanding has been able to advance in the past, and may do so in the future, is that true insights are cumulative and retain their value regardless of what happens to their discoverers; while fads and stunts may bring an immediate profit to the impresarios, but lead nowhere in the long run, cancel each other out, and are dropped as soon as their promoters are no longer there (or have lost the power) to direct the show. Anyway, let us not despair.
