 As pointed out at the outset, the topic of mathematical style is not one of the canonical areas of investigation in philosophy of mathematics. Indeed, this entry is the first attempt to encompass in a single paper the multifarious contributions to this topic. Nonetheless, it should be clear by now that reflection on mathematical style is present in contemporary philosophical activity and deserves to be taken seriously. But the work is just beginning. One needs many more case studies of mathematical styles and a clearer articulation of the epistemological and ontological consequences yielded by different conceptualizations of style. In addition, one would like to see a better integration of all this work with the work on cognitive styles that is found in cognitive psychology and mathematical education. Finally, standard philosophical chestnuts, such as the relationship of form and content to style, and the relation of style to normativity and intentionality would also have to be addressed (for a very good discussion of such topics in aesthetics see Meskin 2005).
