- Spencer "was incapable", our critic haughtily re marks, "of discerning the difference between a homogeneity in matter, necessarily and blindly tending toward a heterogeneity, , and such a law of organism [sic], progress, and growth as requires a spiritual intelligence to originate and maintain it."
