" Pessimism is not in being tired of evil but in being tired of good. Despair does not lie in being weary of suffering, but in being weary of joy. It is when for some reason or other the good things in a society no longer work that the society begins to decline; when its food does not feed, when its cures do not cure, when its blessings refuse to bless. We might almost say that in a society without such good things we should hardly have any test by which to register a decline; that is why some of the static commercial oligarchies like Carthage have rather an air in history of standing and staring like mummies, so dried up and swathed and embalmed that no man knows when they are new or old.
