The Kindle edition of our introduction to the life of Prince Peter Kropotkin: The Anarchist Geographer (Genge Press, 2007) is now selling for £2.67 on Amazon. This is a special summer reduction, so seize this chance to learn more about this fascinating major figure in 19th-century politics. He knew G.B.Shaw, Oscar Wilde and all the leading anarchists and socialists of his day, and was one of the first to challenge the Darwinian idea of the survival of the fittest, proposing instead that humans and animals also cooperate to survive.
