Chris Arthur‟s body of work counts as a very important and original contribution to systematic dialectics, and I have profited immensely from his writings over the years. However we disagree on a number of points. Some have to do with the relatively secondary question of the intellectual relationship between Hegel and Marx; others involve more substantive matters. In his reply to my review of Joseph McCarney‟s Hegel on History Arthur distinguishes three different versions of the thesis that there is a (...) “homology” between the logic of capital (in a Marxian understanding of it) and Hegel‟s “idea.” I shall comment briefly on each and then conclude with a general remark.
