This document discusses how ideas spread in the late 17th and 18th centuries through group gatherings like salons and coffeehouses. Salons were gatherings in private homes that mixed upper and middle classes and sexes, often hosted by important women. Coffeehouses were public spaces that mixed classes and were sites for philosophical debates, current events, and gossip. Both helped spread ideas discussed by philosophers at the time. Print publications like newspapers and novels also contributed to spreading ideas to a growing literate population.
