Abstract
Three elements of late nineteenth century society are examined: imperialism as the urgent moment of sociopolitical necessity, Social Darwinism as compelling ideology of an imperial capitalism, and environmental determinism as first version of modern geography. To legitimate imperial conflict and conquest, sociological principles were derived from biology using the methodological linking device of the organismic analogy. Fundamental differences between humans and the rest of nature could not be comprehended within this methodology. Though aimed at a science of society. Social Darwinism in general and environmental determinism as its geographic version were forced to assume a quasi-scientific form in racism, and nature was given a causal power that could not be scientifically justified. Marxism, by comparison, provides a theoretical basis for scientifically comprehending the relations between nature, production, and society. Following Social Darwinism rather than Marxism prevented geography from achieving a science of environmental relations.
