This paper examines the relationship between science and anarchism in
Kropotkin's theory of mutual aid and analyses it in the light of his c
oncerns about the rise of social democracy and individualism. Tracing
the development of the theory from the 1890s to Kropotkin's death in 1
921, it affirms the centrality of mutual aid in his work but argues, c
ontrary to existing readings, that the theory can be seen as an attemp
t to inspire the revival of the anarchist movement. It concludes that
there is an unresolved tension in Kropotkin's work arising from the im
balance between the idea of a ''natural anarchist tendency'' and anarc
hist propaganda.
