There is an undercurrent to be detected in Anselm's record of the meditative experience that issued in the Ontological Argument and, although it points to a profound and perennial problem in the interpretation of religion, this undercurrent has been largely ignored. The Argument, as is well known, moves entirely within the medium of reflective meaning focused on the idea of God and, unlike the cosmological arguments of later theologians, it makes no appeal whatever to a principle of causality or to the discovery of a sufficient reason for finite existence. Anselm seems to have had his own sense of what one may call the unadulterated rationalism of the Argument when, in his own words, he wondered, ‘if perhaps it might be possible to find one single argument that for its proof required no other save itself, and that by itself would suffice to prove that God really exists’. Here we are entirely within that inner chamber of the mind so dear to the Augustinian tradition, a mind from which one is to exclude all thought save that of God. The task of the one who reflects is to penetrate the inner meaning of this thought in order to discover what it implies beyond what is evident on the surface. With such an eminently rational or logical aim occupying the centre of attention, it is quite understandable that the presence of another, and quite opposed, concern should have been overlooked - Anselm's concern, namely, to transcend, as it were, the medium of thought itself, and enter into the presence of God. The reason that this concern introduces a tension in the search for a proof is that the realization of presence would seem to render proof superfluous, while the inference in an argument - especially one moving towards existence – inevitably suggests, in some sense and to some degree, the absence of what is sought for.
