How did Kropotkin use Mutual Aid to argue for cooperation over competition?

In his influential work Mutual Aid: A Factor in Evolution (1902), Peter Kropotkin challenged the prevailing social Darwinist emphasis on competition by arguing that cooperation is the primary driver of evolutionary success.12

Kropotkin utilized biological and sociological evidence to demonstrate that sociability is a dominant feature across the animal kingdom. He argued that, contrary to the popular interpretation of the "survival of the fittest," species that thrived were those that practiced mutual support rather than conflict.132

He extended this observation to human history, tracing the development of voluntary cooperation from primitive tribes and medieval communes to modern associations like trade unions and the Red Cross. By documenting these patterns, Kropotkin sought to provide anarchism with a scientific basis, asserting that human nature is fundamentally inclined toward decentralized, cooperative societies rather than the competitive, coercive structures of the bureaucratic state. He believed that history pointed toward a future where individuals could develop their creative faculties through mutual aid, free from the interference of centralized authority.3
