“The destruction of the atom [the split of it, in modern physics] seemed to me to be the same as the destruction of the world.... science to me appeared to be dead: its most important basis was only a lunacy, a mistake perpetrated by learned men.... who blindly mistook one object for another.”

Context: Power operates only destructively, bent always on forcing every manifestation of life into the straitjacket of its laws. Its intellectual form of expression is dead dogma, its physical form brute force. And this unintelligence of its objectives sets its stamp on its supporters also and renders them stupid and brutal, even when they were originally endowed with the best of talents. One who is constantly striving to force everything into a mechanical order at last becomes a machine himself and loses all human feeling.
It was from the understanding of this that modern Anarchism was born and now draws its moral force. Only freedom can inspire men to great things and bring about social and political transformations. The art of ruling men has never been the art of educating men and inspiring them to a new shaping of their lives. Dreary compulsion has at its command only lifeless drill, which smothers any vital initiative at its birth and can bring forth only subjects, not free men. Freedom is the very essence of life, the impelling force in all intellectual and social development, the creator of every new outlook for the future of mankind. The liberation of man from economic exploitation and from intellectual and political oppression, which finds its finest expression in the world-philosophy of Anarchism, is the first prerequisite for the evolution of a higher social culture and a new humanity.

The Better Part (1901)
Context: I AM an Anarchist.
All good men are Anarchists.
All cultured, kindly men; all gentlemen; all just men are Anarchists.
Jesus was an Anarchist.
A Monarchist is one who believes a monarch should govern. A Plutocrat believes in the rule of the rich. A Democrat holds that the majority should dictate. An Aristocrat thinks only the wise should decide; while an Anarchist does not believe in government at all. Richard Croker is a Monarchist; Mark Hanna a Plutocrat; Cleveland a Democrat; Cabot Lodge an Aristocrat; William Penn, Henry D. Thoreau, Bronson Alcott and Walt Whitman were Anarchists. An Anarchist is one who minds his own business. An Anarchist does not believe in sending warships across wide oceans to kill brown men, and lay waste rice fields, and burn the homes of people who are fighting for liberty. An Anarchist does not drive women with babes at their breasts and other women with babes unborn, children and old men into the jungle to be devoured by beasts or fever or fear, or die of hunger, homeless, unhouseled and undone.

The Notebooks of Leonardo da Vinci (1883), XX Humorous Writings
Context: Men will seem to see new destructions in the sky. The flames that fall from it will seem to rise in it and to fly from it with terror. They will hear every kind of animals speak in human language. They will instantaneously run in person in various parts of the world, without motion. They will see the greatest splendour in the midst of darkness. O! marvel of the human race! What madness has led you thus! You will speak with animals of every species and they with you in human speech. You will see yourself fall from great heights without any harm and torrents will accompany you, and will mingle with their rapid course.

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...
