“Reading” is one of the most provocative terms in literary theory, in part because it connotes both an activity and a product: on the one hand, an effort to comprehend a text or object of knowledge, and on the other, a more formal response. Both senses of the term originate in the premise that literary and other cultural texts—including performances, scripted or not—require a more deliberative parsing than weather reports and recipes, or sentences like “rain is expected today” and “add one cup of flour.” At the same time, reading serves as an explanatory trope across various sites of 21st-century culture; in a tennis match, players “read” the strengths and weaknesses of their opponents and strategize accordingly; a cab driver “reads” a GPS when plotting an efficient route to convey a passenger. But an engagement with literary and cultural texts is a different matter. In its former sense as a set of protocols or procedures, reading resides at the center of disciplinary debates as newly formed schools, theories, or methods rise to challenge dominant notions of understanding literature, film, painting, and other forms. Frequently, these debates focus on tensions between binary oppositions (real or presumed): casual versus professional reading (or fast vs. slow), surface reading versus symptomatic reading, close reading versus distant reading, and others. Like the term “reading,” readers are variously described as “informed,” “ideal,” “implied,” and more. In some theoretical formulations, they are anticipated by texts; in others, readers produce or complete them by filling lacunae or conducting other tasks. Complicating matters further, reading also exists in close proximity to several other terms with which it is often associated: interpretation, criticism, and critique. Issues of “textuality” introduce yet another factor in disagreements about the priorities of critical reading, as notions of a relatively autonomous or closed work or object have been supplanted by a focus on both historical context and a work’s “intertextuality,” or its inevitable relationship to, even quotation of, other texts. In the latter sense of a reading as an intellectual or scholarly product, more variables inform definitions. Every reading of a text, as Paul Ricouer describes, “takes place within a community, a tradition, or a living current of thought.” The term “reading” is complicated not only because of the thing studied but also because of both the historically grounded human subject undertaking the activity and the disciplinary expectations shaping and delimiting the interpretations they produce. And, in the 21st century, technologies and practices have emerged to revise these conversations, including machine learning, computational modeling, and digital textuality.
