The third element alone remains — the institution itself, acting in such a way as to make social acts a state of habit and instinct. This element — h… - Peter Kropotkin

It is especially in the domain of ethics that the dominating importance of the mutual-aid principle appears in full. That mutual aid is the real foundation of our ethical conceptions seems evident enough. But whatever the opinions as to the first origin of the mutual-aid feeling or instinct may be whether a biological or a supernatural cause is ascribed to it — we must trace its existence as far back as to the lowest stages of the animal world; and from these stages we can follow its uninterrupted evolution, in opposition to a number of contrary agencies, through all degrees of human development, up to the present times. Even the new religions which were born from time to time — always at epochs when the mutual-aid principle was falling into decay in the theocracies and despotic States of the East, or at the decline of the Roman Empire — even the new religions have only reaffirmed that same principle. They found their first supporters among the humble, in the lowest, downtrodden layers of society, where the mutual-aid principle is the necessary foundation of every-day life; and the new forms of union which were introduced in the earliest Buddhist and Christian communities, in the Moravian brotherhoods and so on, took the character of a return to the best aspects of mutual aid in early tribal life. Each time, however, that an attempt to return to this old principle was made, its fundamental idea itself was widened. From the clan it was extended to the stem, to the federation of stems, to the nation, and finally — in ideal, at least — to the whole of mankind.

If on the morrow of the revolution, the masses of the people have only phrases at their service, if they do not recognize, by clear and blinding facts, that the situation has been transformed to their advantage, if the overthrow ends only in a change of persons and forumlae, nothing will have been achieved. … In order that the revolution should be something more than a word, in order that the reaction should not lead us back tomorrow to the situation of yesterday, the conquest of today must be worth the trouble of defending; the poor of yesterday must not be the poor today.

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...
