Between 1800 and 1900 the doctrine of Pie in the Sky gave place, in a majority of Western minds, to the doctrine of Pie on the Earth. The motivating and compensatory Future came to be regarded, not as a state of disembodied happiness, to be enjoyed by me and my friends after death, but as a condition of terrestrial well-being for my children or (if that seemed a bit too optimistic) my grandchildren, or maybe my great-grandchildren. The believers in Pie in the Sky consoled themselves for all their present miseries by the thought of posthumous bliss, and whenever they felt inclined to make other people more miserable than themselves (which was most of the time), they justified their crusades and persecutions by proclaiming, in St. Augustine’s delicious phrase, that they were practicing a “benignant asperity,” which would ensure the eternal welfare of souls through the destruction or torture of mere bodies in the inferior dimensions of space and time. In our days, the revolutionary believers in Pie on the Earth console themselves for their miseries by thinking of the wonderful time people will be having a hundred years from now, and then go on to justify wholesale liquidations and enslavements by pointing to the nobler, humaner world which these atrocities will somehow or other call into existence.
