Recognized for his activism, he was a special guest on the Committee of Science and Technology at the Sixth Pan-African Congress held at Tanzania in 1974. As a social scientist, he sought an all-encompassing social theory for Black people and formulated the concept of Mentacide. To paraphrase, he defined Mentacide as "the planned and systematic destruction of a group's mentality aimed at the destruction of the group." Thus, Black folk alienated from their culture and history eventually lose their sense of purpose and direction, the symptoms of Mentacide. Well aware of the implications of technical advances such as behavior modification and genetic engineering, he presented science as a tool serving greater ends (such as controlling the outcasts of white society), neither objective nor neutral. Being an uncompromising critic of Western society, he wrote the following on the relation of religion to prejudice from "The Psychopathic Racial Personality" in the Fall 1974 issue of Black Books Bulletin: Because of their lack of ethical or moral development, there is no conflict between the white's religion and racial oppression. The white race had historically oppressed, exploited, and killed black [sic] people, all in the name of their god Jesus Christ and with the sanction of their churches. For example, it is generally overlooked that the Ku Klux Klan is primarily a religious organization. Also, blacks [sic] should never forget the Pope [Pius XI] blessing the Italian planes and pilots on their way to bombing Ethiopian men, women, and children who only had spears to defend themselves.
