 Henninger (1989) has individuated arguments by certain orthodox Muslim theologians, the Mutakallimun, that seem to resemble closely Bradley’s regress. Apparently they believed relations to be purely subjective, and argued that positing relations as mind-independent entities would lead to an infinite regress. According to Henninger (1989: 110), a version of this argument can also be found in Harclay, Ockham, and Aureoli.
