While in the course of ages the nucleus of social custom inscribed in law has been subjected to but slight and gradual modifications, the other porti… - Peter Kropotkin

As to the sudden industrial progress which has been achieved during our own century, and which is usually ascribed to the triumph of individualism and competition, it certainly has a much deeper origin than that. Once the great discoveries of the fifteenth century were made, especially that of the pressure of the atmosphere, supported by a series of advances in natural philosophy — and they were made under the medieval city organization, — once these discoveries were made, the invention of the steam-motor, and all the revolution which the conquest of a new power implied, had necessarily to follow... To attribute, therefore, the industrial progress of our century to the war of each against all which it has proclaimed, is to reason like the man who, knowing not the causes of rain, attributes it to the victim he has immolated before his clay idol. For industrial progress, as for each other conquest over nature, mutual aid and close intercourse certainly are, as they have been, much more advantageous than mutual struggle.

The best exponent of anarchist philosophy in ancient Greece was Zeno (342-267 or 270 B.C.), from Crete, the founder of the Stoic philosophy, who distinctly opposed his conception of a free community without government to the state-Utopia of Plato. He repudiated the omnipotence of the State, its intervention and regimentation, and proclaimed the sovereignty of the moral law of the individual — remarking already that, while the necessary instinct of self-preservation leads man to egotism, nature has supplied a corrective to it by providing man with another instinct — that of sociability. When men are reasonable enough to follow their natural instincts, they will unite across the frontiers and constitute the Cosmos. They will have no need of law-courts or police, will have no temples and no public worship, and use no money — free gifts taking the place of the exchanges. Unfortunately, the writings of Zeno have not reached us and are only known through fragmentary quotations. However, the fact that his very wording is similar to the wording now in use, shows how deeply is laid the tendency of human nature of which he was the mouthpiece.

And you, young engineer, you who dream of improving the lot of the workers by the application of science to industry — what a sad disappointment, what terrible disillusions await you! You devote the useful energy of your mind to working out the scheme of a railway which, running along the brink of precipices and burrowing into the very heart of mountains of granite, will bind together two countries which nature has separated. But once at work, you see whole regiments of workers decimated by privations and sickness in this dark tunnel — you see others of them returning home carrying with them, maybe, a few pence, and the undoubted seeds of consumption; you see human corpses — the results of a groveling greed — as landmarks along each yard of your road; and, when the railroad is finished, you see, lastly, that it becomes the highway for the artillery of an invading army...
