In the days of the Austro-Hungarian compromise was reached to hold a two-headed crown with two heads: one in Vienna, and another, in Budapest. But there was a third metropolis to rival them, at least intellectually, and this was Prague, the capital of Bohemia. There were other vital cities, but smaller, and then would be relevant to phenomena such as the birth of the great School of Logic, the Lvov and Warsaw, or other, as Brünn (Brno), Vratislav, Bucuresti, etc. In many of them would radiate the thought that trigger the scientific-philosophical scene for a long time, even to this day.
