He first rose to prominence as a critic of some of the accepted orthodoxies of African intellectuals in the 1960s and 1970s. He was critical of African socialism and all strains of Marxism. He argued that communism was a Western import just as unsuited for the African condition as the earlier colonial attempts to install European type governments. He argued that a revised liberalism could help the continent and described himself as a proponent of a unique ideology of "African liberalism".
