In his Critical Exposition of the Philosophy of Leibniz, the first book he published after his conversion to realism, Bertrand Russell compared Leibniz's cosmological argument for the existence of God with an argument of Bradley's. This is what Russell said about Bradley:

As with many of Russell's comments on Bradley, this one is both insightful and misleading. One of Russell's insights is that the chapters he mentions are parts of a single argument rather than a series of separate ones. Bradley treats categorical, hypothetical, negative, and disjunctive judgments as elements in a “system” of judgments. Another insight is that this system has metaphysical implications, implications that Bradley mentions despite his professed desire, expressed through much of The Principles of Logic, to avoid metaphysics. A final insight is that if Bradley's analysis of these different forms of judgment is correct, then indeed something must exist. None of these insights has been particularly obvious to Bradley's frequently bewildered readers.
