A subject as rich as philosophy can not possibly be limited to or defined through a single tradition or culture. Although most ideologies dominant in philosophy originated from ancient Greece or other western traditions, eastern philosophies also hold an entity of their own and a range of contributions to this school of thought. Several names could be named such as Laozi and Confucius from China and Buddha from India who reformed philosophical generalities in their eras and through a unique standpoint.
During early times, the eastern regions were where religiosity was rampant and widely accepted as the true explanation of the universe and existence. It is for this reason that much of early eastern philosophy did not contribute to the branch of Metaphysics but rather crafted more theories and focused on the branches of morality and political philosophy. It might be because of the geographical distance and a lack of commute among civilizations that eastern and western philosophies developed with a clear boundary until the 19th century when European philosophers sought interest in Indian philosophical scriptures. Today as we see them, many components of eastern philosophy have been dissolved into western philosophy to serve affluent theories that are applicable to humans of all backgrounds.
