Canonization of modernism retroactively defined all later art as its post.

Evidence

This canonical status of modernism seems to be at work even in relation to what has now come to be known as postmodernism. All sorts of distinct movements- Imagism, Surrealism, Dadaism, Cubism, and so onduring the period later came to be canonized under the unified rubric of modernism. Once that category had been set in motion as the art of the twentieth century, however, what came after it could only be seen in relation to it (that is, it could only be a postof modernism itself). — Aijaz Ahmad, In Theory, 484

Categorization

• XREF: Relates to reader’s strategic-essentialism thread: naming a category (‘Third World Literature’) similarly forecloses what questions can be asked of texts in it. — connects to: Modernism was named retroactively while postmodernism preceded its practices — Perry Anderson, The Origins of Postmodernity, 238; Certain modernist precursors already contained what became postmodern
