Everything human is pathetic. The secret source of Humor itself is not joy but sorrow. There is no humor in heaven.

Summary

This quote suggests that human existence, with all its flaws and weaknesses, can be seen as lacking greatness or significance. It argues that humor, rather than stemming from pure joy, finds its roots in our experiences of sorrow or suffering. The implication is that humor acts as a coping mechanism, a way for us to navigate through the hardships of life. The reference to heaven implies that in a perfect or ideal state, where there is no sorrow or suffering, humor would cease to exist.
