Until very recently, most introductory philosophy courses focused exclusively on the Western tradition, indeed mainly on the Anglo-European classics and thinkers. But now there is a much wider variety of work available for introducing students to philosophy that is either explicitly comparative in itself, or that at least makes possible comparative philosophical work. (Some of these works are listed in the bibliography below.)
It should also be noted that all countries, to differing degrees, are functioning in an interdependent globalized environment. Because of immigration, economic and political interdependence, the study of an institutions and/or processes within a single country inevitably gives a reduction in the transferability of the findings. This is because the findings at least are only as applicably transferable as their counterparts are functionally equivalent. It also somewhat fails to account for transnational trends (Franzese, 2007). Alternatively, comparison involving multiple nations, especially using quantitative techniques, can offer valuable empirically-based geopolitical and domestic generalizations. These assist in the evolution of our understanding of political phenomena and produce great recommendations into how to continue particular research using the same form of analysis or a different method all together.
