On the other hand, the cheapest form of pride is national pride; for the man affected therewith betrays a want of individual qualities of which he might be proud, since he would not otherwise resort to that which he shares with so many millions. The man who possesses outstanding personal qualities will rather see most clearly the faults of his own nation, for he has them constantly before his eyes. But every miserable fool, who has nothing in the world whereof he could be proud, resorts finally to being proud of the very nation to which he belongs. In this he finds compensation and is now ready and thankful to defend, … all the faults and follies peculiar to it.
