The Disappointing Study of History
We have actually come to terms quite well with the three great disappointments of mankind—that the earth is not the center of the universe (Copernicus), that man is descended from apes (Darwin) and that we are not masters of our own heads (Freud). Theoretically interesting, pointedly phrased (Freud again), but not really noticeable in everyday life.
Another disappointment, on the other hand, can be felt very well—if one does not deliberately avoid it: the study of history. For a brief, naïve moment, one may believe that the problems facing one personally, society or the entire world are unique and particularly serious. Even a shallow historical look teaches: they are not. Economic history is fairly repetitive anyway, change is currently comparatively slow and low in consequences for those affected (new websites vs. industrialization). Society was once much more divided up to the point of civil war (Weimar Republic), we are quite far away from that today. And besides the threat of extinction by a nuclear war, one may also consider climate change more manageable, especially as low side-effect solutions are known (nuclear power plants).
The fact that one's own problems seem reasonably small and solvable in historical comparison is the much greater disappointment. As if we—despite all reenactment of former struggles—do not heroically lead the most difficult battle of all times, but rather a quite minor secondary one.
