Socialism

Theory is written every day. Just because some of the foundational works that still hold up are hundreds of years old does not mean these are the only works we recommend reading. Gabriel Rockhill for example just came out with a book talking about how the CIA and capitalist institutions monopolize mainstream "radical" theory, twisting it into something that coexists with imperialism, such as the work of Slavoj Zizek.

Secondly, the idea isn't that reading theory will make capitalism wither away, but instead that correct theory informs correct practice. Theory helps us understand capitalism, socialism, imperialism, organization, class struggle, science, culture, art, and helps us figure out how to establish socialism. Trying to reject theory for a monumental task like establishing socialism is like refusing to study physics in trying to land on Mars.
