Critics of the notion of Necessary Being, and critics of arguments for the existence of God, have often claimed to find flaws in the notion or the arguments, and to find flaws that are due to the presence of concealed tautologies. No theist who recalls the unfortunate ‘proof’ of St Anselm and its rejection by St Thomas would dare to claim, his hand on his heart, that tautology has never lurked like a serpent in the garden of natural theology. But the ways in which tautology and talk about God come together on occasion may or may not undermine natural theology in general. I for one am loath to abandon arguments for the existence of God, or give up talk of Necessary Being, since, unlike Professor Findlay, I am unwilling to reverence, much less to worship, a focus imaginarius and I want a real God, or none at all. One of the questions is, of course: does the religious believer want a God who must be too real to be real at all? Another question is: if one can sensibly talk of a God so real as to be Necessary, are there grounds for saying that this possible Necessary Being exists? Between them these questions cover a great part, though by no means all, of the ground of modern discussions on the matter of God.
