I stumbled onto this and the quoted bit really spoke to my experiences:

I lived (as a Very Young Man) through the final years of the dominance of capital-T Theory in English departments, and cringe a bit when I think back on the ways that a sort of hipness or slickness was taken by publishers and even readers as a fully convertable currency in place of thought, practicality, and rigorous argumentation. The whole scene was, to put it bluntly, fucking useless.

Far too often, the form that “political” work in the humanities took was as follows: reassemble theoretical machine in your apartment. Force literary (or other) texts through machine. Scrape up what comes out the other end – generally a fairly bleak picture of our world and our prospects. Strain and mould into monograph. Just before baking, add a few vague, handwaving gestures about practice – gestures generally way out of sync in either their modestness or their hubristic magical thinking with the bleakness of the portrait you’ve just painted. Finally, bake in the glow of your self-admiration – for now you are a servant of revolution, you have changed the world with your book on, say, racial politics in the 19th century novel.

Then all of a sudden, capital-T theory failed. And then one day I was reading an essay about Conrad and imperialism, and noticed something. What the author was discussing was moderately valuable, interesting even. But the rotely grandiloquent claims at the front of the paper seemed to imply that she was in fact, in writing and publishing this paper, doing something about imperialism, racism, and gender imbalance. She gave a sense (and it’s not really her fault – this is just what one did or does in papers like these – it’s a sort of boilerplate that you insert at the front and the back) that a few more papers like this, and, well, we could expect a major improvement in the state of affairs whose backstory she was tracing.

All of a sudden, this seemed criminally untenable to me. It did because it is. And my head was set a-spinning. For this was just the sort of paper that I wrote too – I put the boilerplate in just the same way. Depressing! And so I started thinking about what might be done.

And I’m still thinking. But a few things have become relatively clear to me:

1. We must think steadily, honestly, and realistically about what it is that our works might reasonably do.

2. The fact that they probably won’t spur the immediate resolution of age-old antimonies and contradictions doesn’t mean that they are totally useless.

3. But getting #1 wrong will likely lead them to be useless, yes. Getting #1 right will likely lead to marginal usefulness, and marginal usefulness is better than no usefulness at all.

4. The cultural sphere still is the place where decisions collective and individual are made about who we are, where we’re headed, and what we should do. The base and superstructure are codeterminant. Intervention in culture is still very valuable.

5. You just have to think about which levers you can pull from where you’re standing. And make sure they are the right levers.
