This article traces the evolution by which in the context of 1930s South Africa the liberal philosopher Alfred Hoernlé came to recognize the inability of classical liberalism to address the problems of a society in which a racial hierarchy had become deeply entrenched. Although he must be criticized for his patriarchal approach and for the pessimism that led him to take White attitudes toward Black South Africans as an unchangeable part of the situation that simply had to be accepted, his (...) insight into the limits of liberalism still resonates. While most White commentators were still thinking of racism in terms of beliefs and attitudes, he already understood that the problem lay in the systemic adoption of “techniques of domination” or what we today might call institutional racism. Although his proposal in 1939 that “Total Separation” was “a legitimate application of sound liberal ideas” was deeply problematic in context and might well have had a serious negative impact, it should be understood that it was intended to highlight the fundamental paradox into which liberalism fell when attempting to solve the problems it had helped to create by its belief in a civilizing mission that began with violence.
