Man is appealed to be guided in his acts, not merely by love, which is always personal, or at best tribal, but by his perception of his oneness with each human being. In the practice of mutual aid, which we can re-trace to the earliest beginnings of evolution, we thus find the positive and undoubted origin of our ethical conceptions; and we can affirm that in the ethical progress of man, mutual support- not mutual struggle- has had the leading part.
Peter KropotkinThe mutual-aid tendency in man has so remote an origin, and is so deeply interwoven with all the past evolution of the human race, that is has been maintained by mankind up to the present time, notwithstanding all vicissitudes of history.
Peter KropotkinEach individual is a cosmos of organs, each organ is a cosmos of cells, each cell is a cosmos of infinitely small ones; and in this complex world, the well-being of the whole depends entirely on the sum of well-being enjoyed by each of the least microscopic particles of organized matter. A whole revolution is thus produced in the philosophy of life.
