The society is often a fragmented space of ideas and ideals only harmonized by the agency of collective knowledge, tested, disseminated, and established as an episteme through its educational system. Ideally, the nature of a society usually informs the system and structure of its educational institution. Hence, Nigeria, like every other modern state, has moved through different trajectories that have altered the frame of the institution. The purpose of this paper is therefore propelled by the need to assess how those trajectories have affected the nature of the educational system of a West African country and its society. With the power and agency of colonially introduced Western education still reverberating in the modern state, the chapter taps myriad existing literature on Western education in Africa, Nigeria in particular, to reiterate the need for the decolonization of the Nigerian educational system. To this extent, it concludes on the unarguable note of rethinking Western education and its essence in the country for national cohesion and culture.
