<p>My cat Percy and I both engage in inquiry. For example, we both might wonder where the food is, and look around systematically in an effort to find the food. Indeed, we might even recruit others to help us search for the food, and so engage in collaborative inquiry concerning the location of the food. But such inquiry, even when collaborative, does not amount to <i>research</i>. Why not? What distinguishes research from the kinds of inquiry in which Percy and I can both engage? You might think that research involves the exercise of distinctive skills or capacities, or that it involves focus on a special range of topics. But how can we specify the relevant skills, or the relevant range of topics? This paper articulates and defends an account of research that answers these questions. According to the present account, research is a form of inquiry <i>that is guided by the judgment that the answer to this very inquiry matters to our theoretical understanding</i>.</p>
