The German losses were mostly collateral damage related to the bombings of the cities. The burning of the Polish collections and archives by the German army, on the other hand, was a conscious, deliberate act pertaining to the objective of destroying the culture of the Polish nation – I refer you, amongst other things, to Himmler's and Hitler's clearly expressed intent of razing Warsaw, the nominal, but also cultural and intellectual capital of pre-war Poland, to the ground. That intent is not inherent to war in a universal sense – for one, it is a war crime, for which Alfred Rosenberg was convicted during the Nürnberg Trials – and it looks like you are generally convinced the conduct of the German army in WWII was that like of any other, and that war as carried out by Germany in 1939-1945 was war like any other. At this point, my curiosity in continuing this conversation is limited solely to the question on where you received your history education.
It does not, the German state dropped it for safekeeping in Lower Silesia and according to international law, its ownership was transferred together with the legal status of the respective territories per the Potsdam conference. Any discussion on the possible return of parts of the collection would need to start with the return of the thousands of Polish works of art held in German collections, to which, unlike Poland's legal claim to the Berlinka collection, Germany has none.
My original argument was: "and most of the knowledge lost in the war in todays Poland was actually knowledge of german culture and heritage"
to which I gave a reference that makes a good case for this to be indeed true.
You chose to ignore it and instead resort to talking about something unrelated (intent), which is a straw man, and you also launch an ad hominem, another logical fallacy. You also resort to faulty generalizations.
In case you have overlooked it, here's the most relevant part of the quotes I gave:
> “It is a catastrophe that has no comparison in the history of libraries and in the history of science” (Georg Leyh). We have no account of the demise of German libraries. Germany has lost significant parts of its cultural memory forever.
But it's not a thesis of Die Deutschen Wissenschaftlichen Bibliotheken nach dem Krieg, it's just a quote, and it does not support that "most of the knowledge lost in the war in todays Poland was actually knowledge of german culture and heritage", this is out of the scope of Georg Leyh work
> P.S.: Germany still does not own the Berlinka - https://en.wikipedia.org/wiki/Berlinka_(art_collection)
