Idealism and the Ontological Argument

The ontological proof became something of a signature argument for the British Idealist movement and this paper examines how and why that was so. Beginning with an account of Hegel's understanding of the argument, it looks at how the thesis was picked up, developed and criticized by the Cairds, Bradley, Pringle-Pattison and others. The importance of Bradley's reading in particular is stressed. Lastly, consideration is given to Collingwood's lifelong interest in the proof and it is argued that his attention is best understood as a direct continuation of theirs. In view of the fact that recent commentators have tried to draw a sharp line between Collingwood's approach to metaphysics and ontology and that of his predecessors, the establishment of this connection calls for a measure of reassessment on both sides.     

Kant on the Ontological Argument

The article examines Kant's various criticisms of the broadly Cartesian ontological argument as they are developed in the Critique of Pure Reason. It is argued that each of these criticisms is effective against its intended target, and that these targets include—in addition to Descartes himself—Leibniz, Wolff, and Baumgarten. It is argued that Kant's most famous criticism—the charge that being is not a real predicate—is directed exclusively against Leibniz. Kant's argument for this thesis—the argument proceeding from his example of a hundred thalers—although it may seem to beg the question, in fact succeeds against Leibniz. It does so because the charge of begging the question can be rebutted if one makes certain Leibnizian assumptions.     

Giving the Ontological Argument Its Due

In this paper, I shall present and defend an ontological argument for the existence of God. The argument has two premises: (1) possibly, God exists, and (2) necessary existence is a perfection. I then defend, at length, arguments for both of these premises. Finally, I shall address common objections to ontological arguments, such as the Kantian slogan (‘existence is not a real predicate’), and Gaunilo-style parodies, and argue that they do not succeed. I conclude that there is at least one extant ontological argument that is plausibly sound.     

A Critical Examination of Anselm's Ontological Argument

This paper argues that St.Anselm's distinction of the two senses of existence in his ontological argument for the existence of God renders Paul Tillich's refutation of it invalid.At the same time,Anselm misuses the two types of existence in his ontological comparison,leading to a logical contradiction between the different kinds and degrees of existence.Since Anselm's idea of different reference subjects does not coherently solve this logical absurdity,Anselm's ontological argument falls well short of being a successful approach to establishing the existence of God.     

A Critical Reading of Jean-Luc Marion's Interpretation of Anselm's Ontological Argument

In this essay, I qualify Jean-Luc Marion's anti-ontological interpretation of Anselm's argument. Marion claims that the argument is not ontological but in line with Dionysian apophatic theology. To substantiate his anti-ontological reading, Marion suggests that the main regulative idea of the Proslogion is bonum. The final regulative idea, however, is gaudium, since gaudium, not bonum, leads the argument to the beatific vision. If we reformulate the Proslogion focusing on gaudium, we find that Marion's analysis misses the evident ontological aspects of the argument, such as the tradition of prayer and hermeneutics. Since Anselm promulgated the argument within the Benedictine tradition of Bec, the practice of prayer or meditation is the legitimate context of the argument. However, because of his emphasis on the structure of call and response over the ontological and hermeneutical aspects of revelation, his analysis neglects the importance of the hermeneutic relation within which the Proslogion is born.     

St. Anselm's Ontological Argument as Expressive: A Wittgensteinian Reconstruction

We offer a reading of Anselm's Ontological Argument inspired by Wittgenstein which focuses on the fact that the “argument” occurs in a prayer addressed to God, making it a strange argument since as a prayer it seems to presuppose its conclusion. We reconstruct the argument as expressive. Within the religious perspective, the issues are to be focused on the right object not to present an argument for the existence of God. While this sort of reading lets us understand much about the argument, it also opens new avenues of criticism, one of which is the problem of worship.     

The Principle of Sufficient Reason,the Ontological Argument and the Is/Ought Distinction

Kant's attack on metaphysics consists in large part in his attack on a principle that he names the Supreme Principle of Pure Reason. This principle, it is not often noticed, is the Principle of Sufficient Reason [PSR]. In interpreting this principle as such, I argue that Kant's attack on the PSR (and thereby his attack on dogmatic metaphysics as a whole) depends on Kant's claim that existence is not a first‐order predicate. If existence isn't what Kant calls a real predicate, the PSR is false. While this constitutes a powerful Kantian argument against dogmatic rationalism, it also poses a problem for Kant. For, as I argue, if the PSR is true, Kant's argument that existence isn't a first‐order predicate is false. In this sense, Kant's attack on the PSR is begging the question vis‐á‐vis radical metaphysicians (e.g. Spinoza). Concluding the paper I suggest relying on Kant's 'is'/'ought' distinction in avoiding this circularity, thereby reinforcing the Kantian critique.     

The Importance of Cartesian Triangles: A New Look at Descartes's Ontological Argument

In this paper, I argue that commentators have missed a significant clue given by Descartes in coming to understand his 'ontological' proof for the existence of God. In both the analytic and synthetic presentations of the proof throughout his writings, Descartes notes that the proof works 'in the same way' as a particular geometrical proof. I explore the significance of such a parallel, and conclude that Descartes could not have intended readers to think that the argument consists of some kind of intuition. I argue that for Descartes the attribute of existence is a 'second-order' attribute that is demonstrated to belong to the idea of God on the basis of 'first-order' attributes. The proof, properly understood, is in fact a demonstration. Having brought to light the geometrical parallels between the ontological and geometrical proofs, we have new evidence to resolve the 'intuition versus demonstration' controversy that has characterized much of the discussion of Descartes's ontological argument.     

The Doomsday Argument and the Simulation Argument

The Doomsday Argument and the Simulation Argument share certain structural features, and hence are often discussed together (Bostrom 2003, Are you living in a computer simulation, Philosophical Quarterly, 53:243–255; Aranyosi 2004, The Doomsday Simulation Argument. Or why isn’t the end nigh, and you’re not living in a simulation, http://philsci-archive.pitt.edu/190/; Richmond 2008, Doomsday, Bishop Ussher and simulated worlds, Ratio, 21:201–217; Bostrom and Kulczycki 2011 A patch for the Simulation Argument, Analysis, 71:54–61). Both are cases where reflecting on one’s location among a set of possibilities yields a counter-intuitive conclusion—in the first case that the end of humankind is closer than you initially thought, and in the second case that it is more likely than you initially thought that you are living in a computer simulation. Indeed, the two arguments do have some structural similarities. But there are also significant disanalogies between the two arguments, and I argue that these disanalogies mean that the Simulation Argument succeeds and the Doomsday Argument fails.
