This whole thing came up in a seminar in which I put forward the notion that we come to a text with as few expectations as possible, read it, and then decide how much further reading of text or looking to context is appropriate to get yourself the level of explanation you desire (I also argued, in fairness, that there’s something analytical or logical in most texts that we can disucss the merits of in the total absence of context). I’ve encountered resistance to textualism before, but it’s never taken the form of other people telling me what’s going on in my head when I read, which I really, really object to.
