Where does genius collide?

In eighteenth-century aesthetics genius came to mean an inborn creative power that produces original art without following learned rules. Edward Young's Conjectures on Original Composition (1759) argued that true genius grows its own works as a plant grows and owes nothing to imitation. Immanuel Kant's Critique of the Power of Judgment (1790) gave the meaning its most influential form, defining genius as the inborn talent through which nature gives the rule to art. Here the referent is a faculty of original creation in the fine arts, and it is distinct from a Roman guardian spirit and from a measured level of intelligence.[1][2]

In psychology genius came to name an extreme degree of intellectual ability, studied first through heredity and later through testing. Francis Galton's Hereditary Genius (1869) treated eminence as a measurable and inheritable trait and ranked people by reputation and ability. Lewis Terman's Genetic Studies of Genius (1925) followed a large group of very high scoring children across their lives and tied the label to a high intelligence quotient. Here the referent is a level of measured cognitive ability in a person, and it does not name a protective spirit or an artist's creative faculty.[3][4]
