Colonization, which has resulted in the direct contact between the black man and the white man, leaves behind it an eternity of realities, of questioning and even an identity crisis. It was imposed on Africans by means of force, leaving no room for the concept of balance, equality or even of brotherhood. Instead you are faced with the concept of dominance between oppressors and oppressed. During colonization the white man had managed to impose its superiority to the black man by creating an absolute hierarchy: the white man is the all-powerful, the civilized, the absolute master of all, it is superior to all indigenous black; the black man, in the opposite, is found stripped of its roots, its customs, its history, in short it is found lower than the white man. In this work it was question to analyze the process of the demystification of the white man by the black man through Ferdinand Oyono’s Houseboy. We should then, through a study of this novel and other materials, show how this demystification is highlighted. By analyzing this novel and Toundi building his life the kingdom of the West, which will enable him to see more clearly in the behavior of its masters and demystify as well their universalist claims that their claims to the humanism ; we understand then the process and the circumstances which have enabled this demystification. The white man is debunked. Its superiority and its all-powerful are rendered to zero by the degradation of morals characterizing its way of life.
