Oppenheimer, PE, Zalta, EN., On the Logic of the Ontological Argument, Originally published in Philosophical Perspectives 5: The Philosophy of Religion, James Tomberlin (ed.), Atascadero: Ridgeview, 1991: 509–529. "Even if one were to construe the word 'can' in the definite description 'that than which none greater can be conceived' in terms of metaphysical possibility, the logic of the ontological argument itself doesn't include inferences based on this modality".
