"The more specific idea of Evolution now reached is - a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter"
About this Quote
The subtext is that change is not merely constant; it is legible, trending, and, crucially, improvable. Spencer pairs this with the language of physics (“dissipation of motion,” “integration of matter”) to give moral and social assumptions the sheen of thermodynamic inevitability. If evolution is what matter does, then social stratification, industrial specialization, and imperial “development” can be smuggled in as nature’s own preference for “coherent heterogeneity.” That’s why his phrasing matters: it narrows the room for dissent. To argue against Spencer starts to sound like arguing against the universe.
Context sharpens the ambition. Writing after Darwin but not confined by Darwin, Spencer is building “synthetic philosophy,” a system meant to unify biology, psychology, sociology, and ethics under one principle. The intent isn’t humility before complexity; it’s a confident attempt to turn complexity into a law - and to make that law feel like common sense.
