problematic. His research on ubuntu presents an alternative collective discourse on African philosophy that takes differences, historical developments, and social contexts seriously. According to Edwin Etieyibo and Jonathon O. Chimakonam in their article “African Philosophy: Past, Present, and Future”, historical context plays an important role in African philosophy. History provides the framework in which we can inspect philosophical problems. In terms of African philosophy, one must look at the whole picture through the lens of African history. “There are no facts without history." African philosophy can be formally defined as a critical thinking by Africans on their experiences of reality. Nigerian born Philosopher K.C. Anyanwu defined African philosophy as "that which concerns itself with the way in which African people of the past and present make sense of their destiny and of the world in which they live. Nigerian philosopher Joseph I. Omoregbe broadly defines a philosopher as one who attempts to understand the world's phenomena, the purpose of human existence, the nature of the world, and the place of human beings in that world. This form of natural philosophy is identifiable in Africa even before individual African philosophers can be distinguished in the sources. Like Western philosophy, African philosophy contemplates the perceptions of time, personhood, space and other subjects. History There is a rich, and written, history of ancient African philosophy - for example from ancient Egypt, Ethiopia, and Mali (Timbuktutu, Djenne). When it comes to the modern era and the 20th century, a new beginning is linked to the 1920s, when African individuals who had studied in the United States and Europe ("Western" locations) returned to Africa and reflected on the racial discrimination experienced abroad. Their arrival back in Africa instigated a feeling of onuma, which is an interpretation of "frustration." The onuma was felt in response to legacies of colonialism on a global scale. The renaissance of African philosophy in the 20th century is important because onuma inspired some who had traveled and returned to formulate a "systematic beginning" of philosophizing the African identity, the space of African people in history, and African contribution to humanity. Criteria According to some, two conflicting components are deemed integral to a work for it to be considered African philosophy. First, the piece must have a racial focus. This facet is valued by Traditionalist groups, who posit that African philosophy should be an expression of the world experienced by African individuals.
