The Modern philosophy

Modern philosophy is philosophy done in Europe and North America between the 17th and early 20th centuries. It is not a specific doctrine or school, (and so should not be confused with Modernism) although there are certain assumptions common to much of it, which helps to distinguish it from earlier philosophy.
The 17th and early 20th centuries roughly mark the beginning and the end of modern philosophy. How much if any of the Renaissance it should include is a matter for dispute; likewise modernity may or may not have ended in the twentieth century and been replaced by post-modernity. How one decides these questions will determine the scope of one's use of "modern philosophy". The convention, however, is to refer to philosophy of the Renaissance prior to Rene Descartes as "Early Modern Philosophy" (leaving open whether that puts it just inside or just outside the boundary) and to refer to twentieth-century philosophy, or sometimes just philosophy since Wittgenstein, as "Contemporary Philosophy" (again, leaving open whether or not it is still modern). This article will focus on the history of philosophy beginning from Descartes through the early twentieth century ending in Ludwig Wittgenstein.
