The subject of passion arose recently in this electronic space, and it sprang loose a quote that I have yet to come to grips with, almost twenty years after encountering it as an epigraph to a book by Don Robertson:

Passions are not natural to mankind; they are always exceptions or excrescences. The ideal, genuine man is calm in joy and calm in pain and sorrow. Passions must quickly pass or else they must be driven out.

Said by Johannes Brahms, in a letter dated 17 October 1857.
