"That the variability of an organism to a certain extent is a constant and certain condition of life we admit, otherwise there would be no distinguishable individuals of a species"
About this Quote
The subtext is a quiet power struggle over who gets to define life’s order. Owen, famous for coining “Dinosauria” and for his battles with Darwin’s camp, accepts variation only “to a certain extent.” That hedge is doing heavy lifting. He concedes difference as “constant” and necessary for individuality, but tries to cordon it off from the more explosive implication: if variation is built in, what stops it from accumulating into new forms? The sentence reads like a pressure valve, releasing just enough steam to keep the boiler from bursting.
Context matters: mid-19th century Britain was awash in specimens from empire, museums, and comparative anatomy. The data were messy. Owen’s intent is stabilizing: to preserve meaningful species distinctions while granting nature its everyday untidiness. Ironically, the logic also feeds the evolutionary argument he resisted. If individuality requires variability, the boundary between “distinguishable individuals” and “different species” starts to look less like a wall and more like a negotiated line.
