Again, a little political theory is called for. When studying any political philosophy, above all else, it is essential to consider the thinker's view of human nature. Bakunin's view of the human nature question was much more organic than that of Jean-Jacques Rousseau or John Locke. It progresses slowly, through the momentum imparted by individual initiatives, not through the mind and will of the legislator. The main idea in both philosophies is the unity of all the classes that will eventually lead to the absence of all classes.
Individuality necessarily leads to discord and dissent.
If discord and dissent are present and there is no external referent to temper them, there will be chaos. One cannot promote a new political ideology on the premise that it will breed chaos. Bakunin basically argues that because society is organic people will behave in an orderly fashion. The state, which is instituted to maintain order and to protect, will become unnecessary. Therefore, Bakunin might argue that it would not be in the interest of a member of an anarchistic society to murder another member because that murder is not prohibited by a repressive and domineering state.
