One of my favourite books of all time. I even did my thesis on it. I would highly suggest it to anyone. Though negated by modern sciences and psychology you will be amazed how much of social Darwinism still lurks in today's "common sense" as manufactured by ones in control. Usually the arguments that are quite famous and repeated often to support capitalism and fascism still unconsciously arise from long negated but not yet dead social Darwinism. This work is the only complete response and scientific negation of social Darwinism. Social Darwinism in the past has been a weapon of fascists, totalitarians (tankies), and capitalists alike to support their arguments. You will be amazed how many common arguments in favour of racism, colonization, patriarchy and the mindset of such poisonous nature are production of social Darwinism. Kropotkin was amazing! I love all of his writings.
