A teenaged girl, her arms resting on the machine, in quiet contemplation. A young man shielding his eyes from the brilliance of the light emanating from the center, and a young woman staring unblinkingly. A standing man taking copious notes on the proceedings. Another man leaning back in his seat, listening intently to the gray-haired lecturer, captivating his audience like a magician. >A key idea of the Age of Enlightenment—that empirical observation grounded in science and reason **could best advance society**—is expressed by the faces of the individuals in Joseph Wright of Derby’s A Philosopher Lecturing on the Orrery. >Wright’s painting encapsulates in one moment the Enlightenment, a philosophical shift in the eighteenth century away from traditional religious models of the universe and toward an empirical, scientific approach. It is important to note the term given this new way of thinking. “Enlightenment” indicates an active process, undertaken by an individual by group. >The age of Enlightenment is most closely associated with scientists and inventors, but writers and artists also played major roles. They helped spread enlightenment concepts via the written word and printed image, and inspired others to think rationally about the world in which they lived. The provincial English painter Joseph Wright of Derby became the unofficial artist of the Enlightenment, depicting scientists and philosophers in ways previously reserved for Biblical heroes and Greek gods.
