As death, when we come to consider it closely, is the true goal of our existence, I have formed during the last few years such close relationships with this best and truest friend of mankind that death's image is not only no longer terrifying to me, but is indeed very soothing and consoling, and I thank my God for graciously granting me the opportunity...of learning that death is the key which unlocks the door to our true happiness. I never lie down at night without reflecting that —- young as I am — I may not live to see another day. Yet no one of all my acquaintances could say that in company I am morose or disgruntled.

WOLFGANG AMADEUS MOZART, letter to Leopold Mozart, Apr. 4, 1787

I think this is along the lines of the existential philosophy.
