Meant is a government from above, managed by theoretically trained specialists, men and women who are presumed to be capable to boss the society. They make it appear as if they are acting for the benefit of the people, but actually they grimly try to realize their own blueprints of a well-regulated world. It isn't difficult to understand that their political ideas never correspond to the little everyday things of life. These things can't be calculated beforehand and it is impossible to provide them by law and other rules. But especially these everyday things are the essence of life.
Life is a sequence of unpredictable and non-reproducible events.
Nobody can really control them. So the politics are even dangerous delusions, in spite of the goodness and integrity of many modern politicians. At the time of the Enlightenment almost every thinker believed that on the long term the sciences should drive away all delusions and nonsense and give people something to hold on. The common opinion in the 18th and 19th century was that in the near future man would become a soberly thinking realist and even a rationalist. Scientific knowledge would take the place of religious and other supernatural drivel.
