Section 9
Letter to a Priest (1951)
Context: Besides, it is written that the tree shall be known by its fruits. The Church has borne too many evil fruits for there not to have been some mistake at the beginning. Europe has been spiritually uprooted, cut off from that antiquity in which all the elements of our civilization have their origin; and she has gone about uprooting the other continents from the sixteenth century onwards. Missionary zeal has not Christianized Africa, Asia and Oceania, but has brought these territories under the cold, cruel and destructive domination of the white race, which has trodden down everything. It would be strange, indeed, that the word of Christ should have produced such results if it had been properly understood.

Canto I, stanza 8.
The Corsair (1814)

Preface to the first edition, written in the summer of 1950.
The Origins of Totalitarianism (1951)
Context: The totalitarian attempt at global conquest and total domination has been the destructive way out of all impasses. Its victory may coincide with the destruction of humanity; wherever it has ruled, it has begun to destroy the essence of man. Yet to turn our backs on the destructive forces of the century is of little avail.
The trouble is that our period has so strangely intertwined the good with the bad that without the imperialists' "expansion for expansion's sake," the world might never have become one; without the bourgeoisie's political device of "power for power's sake," the extent of human strength might never have been discovered; without the fictitious world of totalitarian movements, in which with unparalleled clarity the essential uncertainties of our time have been spelled out, we might have been driven to our doom without ever becoming aware of what has been happening.
And if it is true that in the final stages of totalitarianism an absolute evil appears (absolute because it can no longer be deduced from humanly comprehensible motives), it is also true that without it we might never have known the truly radical nature of Evil.

The Day After the World Ended, notes for a speech at DeepSouthCon'79, New Orleans (21 July 1979), later published in It's Down the Slippery Cellar Stairs (1995)
Context: Science Fiction has long been babbling about cosmic destructions and the ending of either physical or civilized worlds, but it has all been displaced babble. SF has been carrying on about near-future or far-future destructions and its mind-set will not allow it to realize that the destruction of our world has already happened in the quite recent past, that today is "The Day After The World Ended". … I am speaking literally about a real happening, the end of the world in which we lived till fairly recent years. The destruction or unstructuring of that world, which is still sometimes referred to as "Western Civilization" or "Modern Civilization", happened suddenly, some time in the half century between 1912 and 1962. That world, which was "The World" for a few centuries, is gone. Though it ended quite recently, the amnesia concerning its ending is general. Several historiographers have given the opinion that these amnesias are features common to all "ends of worlds". Nobody now remembers our late world very clearly, and nobody will ever remember it clearly in the natural order of things. It can't be recollected because recollection is one of the things it took with it when it went...
