 Part of what this section aims to make clear is the variety of views that might be seen as intentionalist. Intentionalism may be either externalist or not, reductive or not. Further, intentionalisms may be, as already suggested, either more or less restrictive or inclusive (and this in various ways). And they may be either completely non-reflexivist, or in some respect reflexivist—where the latter category is very heterogeneous, and can encompass deeply divergent views. And both of these latter contrasts admit of being developed in diverse, and either reductive or non-reductive ways. Section 6 will explore the inclusive/restrictive contrast and some of the positions that have appeared along this dimension, and Section 7 some varieties of reflexivist notions. Before delving into these complications, the reader may wonder what is supposed to justify intentionalism, and how the issues of this section might appear from the phenomenological perspectives canvassed in Section 3. Discussion of the first question can be found in the supplement,  Arguments for Intentionalism.  The second question is discussed in the supplement,  Phenomenology and Intentionalism.
