William Lane Craig says, "this need not be a gross hedonism," as "man on this level could be very cultivated and even circumspect; but nevertheless his life revolves around himself and those material things- whether sex, art, music, or whatever- that brings him pleasure. The paradox of life on this level is that it leads ultimately to unhappiness.
The self-centered, aesthetic man finds no ultimate meaning in life and no true satisfaction. Thus the aesthetic life leads finally to boredom, a sort of sickness with life."
William Lane Craig, "Reasonable Faith," 69
