ELI5 What’s modernism and post-modernism?
gpt
Modernism was a movement in art and culture in the late 19th and early 20th century that was obsessed with new ways of doing things, owing in part to the technological and scientific advances of the era. Modern art, for example, eschewed realism in favor of abstraction and surrealism. Modernists would reject traditional ways of doing things simply because they were traditional. In the words of Vladimir Mayakovsky, a modernist Russian poet, they wanted to “throw all the old ways overboard from the Steamship of Modernity.”

Post-Modernism came about in the mid to late twentieth century and was a reaction to Modernism. Whereas Modernists would reject traditional art and culture, Post-Modernism draws on both traditional as well as Modernist design. Post-Modern architecture for example might be modern in design but with Greek-style columns as a playful reference to Classical architecture. Post-Modern art and design is known for these “references” and commentaries on other work. These references are why Post-Modern art is sometimes considered “meta,” referring to itself or the medium in a provocative way.
