Philosophical studies of complex scientific concepts are predominantly “adaptationist,” arguing that conceptual complexity serves important purposes. This is a historical artifact. Having had to defend their views against a monist presumption favoring simpler concepts, pluralists and patchwork theorists felt compelled to show that complexity can be beneficial. This neglects an alternative possibility: Conceptual complexity is largely neutral, persisting simply because it does little harm. This article defends the neutral theory of conceptual complexity in two forms: (a) as a plausible theory in its own right and (b) as a useful foil for adaptationist arguments.
