Pieper: "The wonder of this world"
"In Hans Reichenbach's programmatic book, Aufstieg der wissenschaftlichen Philosophie ["The Rise of Scientific Philosophy"], we read: "The philosopher seems incapable of controlling his craving for knowledge." But is this not, we may say, an entirely appropriate observation? Our longing for knowledge is indeed beyond our control. Is this not what Plato had in mind when he compared the philosopher to the lover? The philosopher, too, is "beside himself" because he is moved to the core by the mirandum, the wonder of this world. We can wholeheartedly agree. What bedevils this insight, however, is the fact that Plato praises what the "scientific philosophy" rejects and disqualifies without feeling the need for further arguments: it shows a lack of discipline even to talk about things beyond our understanding!
Regarding the nature of the so-called "scientific philosophy", Pieper explains that "The most direct formulation is found in the positivist manifesto, Wissenschaftliche Weltauffassung ["The Scientific World View"], of the early Vienna Circle: "What is, is on the surface; everything is accessible to human perception." Thus it is nonsensical so much as to search for a "root" of all things or for their "ultimate reasons". In short, that mysterious object of philosophy is nonexistent. Only the objects of science are real; they are, in strict sense and without exception, the objects of perception."
