 Rejectionists about Bradleyean arguments tend to question one or more of the assumptions on which the argument rests. With respect to the regresses, rejectionists have mainly questioned the grounds of Bradley’s skepticism about relations and their relating role. As we have seen in section 1.3 above, Russell employed this strategy when debating Bradley in the journal Mind, in 1910. On that occasion, Russell argued in favor of external relations and their relating role within complexes of the form  aRb.[3]
