"As an economist what I think would be really interesting would be a critical comparison of the rise in theory in the (or one of the) humanities (like literary criticism) with the rise and complete imperial dominance of theory in economics. Why was the former so much less successful and transitory than the latter? Why was the introduction of theory in literary criticism thought to be so transgressive and radical in the humanities both by its proponents and its critics, while theoretical economics was so often viewed as complementary to the status quo (word?) and even reactionary by its critics and (implicitly) by its exponents."
