Contemporary writings on friendship all point to a lacuna in modern literature. But toward the end of the twentieth century this gap was being addressed by various challenges, both to the impartiality of liberalism and to the objectivity of modernism by movements such as communitarianism, feminism, and post-modernism, which created a rich and ongoing scholarly debate and which resurrected some of the ideals of classical philosophy in an attempt to recognize the valuable role that can be played by friendship in the twenty-first century.
