I am an anarchist and I overall like this text, I think it's a good introduction to get some complete basics of what are the goals of anarchists and how they think about the world. I consider his opinion about human nature naive, but given that this is an introductory texts I don't have a problem with that and I like to recommend it to people that want to learn a bit about anarchist movement that has over 150 years history of fighting against every authoritarianism possible and is steadily growing in popularity around the world, inspiring new generations of freedom fighters.
