"As soon as I am outside my religious understanding, I feel as an insect with which children are playing must feel, because life seems to have dealt with me so unmercifully; as soon as I am inside my religious understanding, I understand that precisely this has absolute meaning for me. Hence, that which in one case is a dreadful jest is in another sense the most profound earnestness. Earnestness is basically not something simple, a simplex, but is a compositum [compound], for true earnestness is the unity of jest and earnestness."
