Abstract: This paper examines the career of the prominent intellectual and activist Zachariah Keodirelang Matthews and his efforts to promote higher education for black South Africans during the mid-twentieth century. Popular narratives of South African history often tend to downplay or discredit the moderation, pragmatism and cultural diversity of Matthews and his generation and instead emphasize the growth of black solidarity and militancy, but study of Matthews’ writings reveals the important role of old liberal ideas in African nationalism, including an enduring faith in the power of knowledge and an expectation that justice would eventually prevail. The life and work of Z.K. Matthews demonstrates how an African teacher and scholar could steadfastly resist European domination while simultaneously maintaining belief in the essential oneness of humanity and hope for the future of South Africa.
