Efforts aimed at addressing the causes of gender-based violence (GBV) do not consider how the traditional concept of gender shapes attitudes towards GBV in Yoruba communities. This study grounds the differences between the traditional western and Yoruba concepts of gender within the context of the two major theories of persistence in metaphysics: endurantism and perdurantism It is argued that the traditional western concept of gender influences the Yoruba concept of gender in perpetrating GBV. In curbing the menace of GBV among the Yoruba, the study advocates a redefinition of the concept of gender towards the traditional Yoruba virtue of mutual respect between genders. The study employs the method of textual interpretation, argumentative discourses of metaphysical positions and analysis of concepts of GBV. The study concludes that redefining the Yoruba concept of gender within the traditional Yoruba culture as a perdurantist account of gender will address the crisis of gender-based violence.
