Richard Stanley Peters was one of the founding fathers of analytic philosophy of education in the twentieth century. After reviewing Peters' disentanglement of the ambiguities of liberal education, I reconstruct his view on the status and the existential foundations of the humanities. What emerges from my reconstruction is an original justificatory argument for the value of liberal education as general education in the sense of initiation into the heritage of the humanities. To close, I evaluate the scope and power of this argument from the existential concern of the humanities.
