As near as I come to understanding it, Kropotkin proposed that an anarchal system, instead of being endlessly chaotic, will gradually settle into a social order. This is not, however, the "whoever has the biggest gun is the top dog" type scenario that most believe anarchy would degenerate into. Kropotkin thought that people in an anarchal system would eventually find their niche, doing whatever it was that came naturally to them, and society would emerge from that.
