I guess both would be good, but especially literally criticism and in the humanities/social sciences.
I think that, within literary criticism, etc., the post-moderns and deconstructionists makes some valid points. It is correct that literature can represent different voices, and some of these representations reflect different power relations. To use an example from history, it is true, for example, that Greek and Roman accounts of barbarians cannot necessarily be taken at face value - they reflect cultural biases and traditions of interpretation, though I'm not sure it required the post-moderns to tell us this. But I think the post-moderns and deconstructionists make far too much of these insights, turning literature or history or culture into simply a matter of power relations - with no room for other motives beyond social and political power nor room for genuine wisdom or artistic merit - and proliferating disunity and differing voices to the complete exclusion of any unity or universal themes or meaning.
