In the twilight of late enlightenment, the insight gains shape that our "praxis," which we always held to be the most legitimate child of reason, in … - Peter Sloterdijk

The establishment of inwardness and the creation of the illusion of privacy are the most subversive themes of enlightenment. It is still not really clear today who the social conveyor of this impulse of enlightenment may be. One of the ambivalences of enlightenment is that although intelligence can be explained sociologically, educationally, and politically, “wisdom,” self-reflection cannot. The subject of a radical ego enlightenment cannot be socially identified with certainty—even though the procedures of this enlightenment are anchored in reality. In this point, the majority of societies seem to strive for a conscious nonenlightenment.

Philosophy … lost its prestige to the extent that it lost its evident advantage in cleverness to "normal life." In the transition from archaic teachings of wisdom to philosophy based on argument, it itself was engulfed in the twilight of alienation from life. It had to accept that the independent cleverness theories of pragmatics, economics, strategy, and politics proved themselves to be its better, until, with its logical niceties, it became infantile and academic, and stood there as the Utopian idiot with its reminiscences about great ideals. Today philosophy is surrounded on all sides by maliciously clever empiricisms and realistic disciplines that "know better."

If the movements of reflection in classical philosophy could be depicted in the structure of Homer's Odysseus, in which a wandering hero returns home via a thousand false paths across the whole world, in order there to be recognized by his woman, that is, by his "soul," then the reflections of modern thinking in no way still find their way back "home." They either move on the spot in essenceless flurries, drained of experience, or they drift on, like the eternal Jew or the Flying Dutchman, without hope of arriving, through the perpetually alien. … For the modern subject, a "vagabond in existence," there is no longer any return home.
