"The intellectual evolution of the race consists in an increase in the number, delicacy, complexity, permanence and speed of formation of such associations"
About this Quote
The intent is quietly polemical. Thorndike is writing against romantic accounts of genius and against lofty, moralized notions of “civilization.” Intelligence, in this view, isn’t a single faculty you either possess or don’t; it’s a scalable skill in connecting experiences. That makes the mind a target for training, standardization, and, inevitably, ranking. The subtext is that education and social policy can be engineered: change the environment, reinforce the right connections, and you change the person. It’s the psychological groundwork for everything from modern schooling’s obsession with outcomes to today’s behavior-shaped interfaces.
Context matters because Thorndike sits at the dawn of American scientific psychology, when measurement was becoming a cultural faith. Words like “race” carry the period’s sweeping, species-level ambition - and its blind spots. By abstracting people into association-making systems, he achieves explanatory power while also flattening the messy realities of culture, inequality, and meaning. The line works because it’s both clinical and totalizing: a definition that smuggles in a program.
