It is futile to speak of liberty as long as economic slavery exists. "Speak not of liberty — poverty is slavery!" is not a vain formula; it has penet… - Peter Kropotkin

Take any work on astronomy of the last century, or the beginning of ours. You will no longer find in it, it goes without saying, our tiny planet placed in the center of the universe. But you will meet at every step the idea of a central luminary — the sun — which by its powerful attraction governs our planetary world. From this central body radiates a force guiding the course of the planets, and maintaining the harmony of the system. Issued from a central agglomeration, planets have, so to say, budded from it; they owe their birth to this agglomeration; they owe everything to the radiant star that represents it still: the rhythm of their movements, their orbits set at wisely regulated distances, the life that animates them and adorns their surfaces. And when any perturbation disturbs their course and makes them deviate from their orbits, the central body re-establishes order in the system; it assures and perpetuates its existence.
This conception, however, is also disappearing as the other one did. After having fixed all their attention on the sun and the large planets, astronomers are beginning to study now the infinitely small ones that people the universe. And they discover that the interplanetary and interstellar spaces are peopled and crossed in all imaginable directions by little swarms of matter, invisible, infinitely small when taken separately, but all-powerful in their numbers.

Thousands of writers, of poets, of scholars, have laboured to increase knowledge, to dissipate error, and to create that atmosphere of scientific thought, without which the marvels of our century could never appeared. And these thousands of philosophers, of poets, of scholars, of inventors, have themselves been supported by the labour of past centuries. They have been upheld and nourished through life, both physically and mentally, by legions of workers and craftsmen of all sorts. They have drawn their motive force from the environment.

Vladimir Ilyich, your concrete actions are completely unworthy of the ideas you pretend to hold. Is it possible that you do not know what a hostage really is — a man imprisoned not because of a crime he has committed, but only because it suits his enemies to exert blackmail on his companions? … If you admit such methods, one can foresee that one day you will use torture, as was done in the Middle Ages. I hope you will not answer me that Power is for political men a professional duty, and that any attack against that power must be considered as a threat against which one must guard oneself at any price. This opinion is no longer held even by kings... Are you so blinded, so much a prisoner of your own authoritarian ideas, that you do not realise that being at the head of European Communism, you have no right to soil the ideas which you defend by shameful methods … What future lies in store for Communism when one of its most important defenders tramples in this way every honest feeling?
