Moderate communitarianism is different: A Response to J. O. Famakinwa and B. Matolino
Moderate communitarianism is a thesis introduced into African philosophical literature by the Akan philosopher Kwame Gyekye. He suggests that this thesis better accounts for the Akan and, to some extent, African social set-up than what he calls radical communitarianism (a thesis which he attributes especially to John Mbiti and Ifeanyi Menkiti). However, Gyekye is criticised by J. O. Famakinwa and B. Matolino for...
