How is it possible that suffering that is neither my own nor of my concern should immediately affect me as though it were my own, and with such force… - Arthur Schopenhauer

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. (From 'Parerga and Paralipomena', Vol. 1, Aphorisms on the Wisdom of Life, 'What A Man Represents', pp. 360)

Alles, alles kann einer vergessen, nur nicht sich selbst, sein eigenes Wesen.

For the purpose of acquiring gain, everything else is pushed aside or thrown overboard, for example, as is philosophy by the professors of philosophy.
