In this paper I propose to examine the cognitive status of mystical experience.

There are, I think, (at least) three distinct but overlapping sorts of religious experience. (1) In the first place, there are two kinds of mystical experience. The extrovertive or nature mystic (in some sense) identifies himself with a world which is both transfigured and one. The introvertive mystic withdraws from the world and, after stripping the mind of concepts and images, experiences union with something which (in some respects at least) can be described as an undifferentiated unity. Introvertive mysticism is a more important phenomenon than extrovertive mysticism. (2) Numinous experiences are complex experiences involving dread, awe, wonder, and fascination. One (apparently) finds oneself confronted with something which is radically unlike ordinary objects. Before its overwhelming majesty and power, one is nothing but dust and ashes. In contrasting oneself with its uncanny beauty and goodness, one experiences one's own uncleanness and ugliness. (3) The experiences bound up with the devotional life of the ordinary believer (gratitude, love, trust, filial fear, etc.) are also religious in character. Nevertheless these more ordinary experiences should, I think, be distinguished both from numinous experiences and from mystical experiences, for they do not appear to involve the sense of immediate presence which characterises the latter.

Anselm built his meditation Proslogion on the formula ‘that than which nothing greater can be conceived’. The peculiarity of this phrase has been often remarked but not, I believe, fully appreciated. Properly understood, I shall argue, this formula, although unable to support the so-called ontological argument, throws important light on the logic of the religious use of the word ‘God’. My argument will turn on the difference between the two uses of the verb ‘conceive’ in Anselm's claim that we can conceive of that than which nothing greater can be conceived.

It appears to me that most traditional criticism of the Ontological argument misses the mark because the proponents imply a premise which, if true, would validate their argument on precisely the point attacked by the opponents. In view of this possibility, I propose the following analysis:

(1) state the traditional ontological argument without the implied premise;

(2) state the traditional criticisms, showing how they miss the mark;

(3) restate the ontological argument with the implied premise made clear;

(4) offer a defence of the implied premise;

(5) show how the ontological argument is still invalidated by another criticism;

(6) argue that the only way to avoid this other criticism is to borrow another premise from the cosmological argument, and

(7) that when these premises are borrowed the result is a valid form of the cosmological argument for the existence of a necessary being.

In the philosophical world Anselm is known almost exclusively for the work in his two earliest writings, the Monologion and Proslogion, which, of course, includes his celebrated ontological argument for the existence of God. It is unfortunate that the rest of his work is not more widely known, for he makes some important contributions to western thought in later treatises that are virtually unknown to present-day philosophers and theologians. One such contribution is his concept of freedom, which he explains and defends primarily in De Libertate Arbitrii (hereafter DLA), written somewhere between 1085 and 1090. Anselm's concept of freedom is important for a number of reasons. First, he argues for a definition of freedom which is significantly different from others found in the history of western thought. Second, in his investigation of freedom he makes use of a methodological procedure which in certain respects has striking similarities (though there are also important differences) to certain analytic techniques well-known today. And finally, the single definition that Anselm provides is intended to include in its compass two major and seemingly different senses of ‘freedom’.

The status of religion in the modern world is intimately related to the rise of science. The clearest way of getting at this relation is to consider the issue of miracle. Given the success of scientists in predicting and controlling natural phenomena, many of the leading theologians of the modern era abandoned the understanding of miracle as a supernatural violation of natural regularities. They conceded the capacity of scientists to offer natural explanations of phenomena that are naturally observable and shifted their theological focus from the observable patterns of nature to morality, religious experience, and history. Although many liberal and existentialistic theologians affirmed the miraculous, especially with regard to the Resurrection, they avoided a head on collision with science.

Since the last half of the nineteenth century western Christian theologians have argued periodically about the supernatural, with liberals ordinarily denying the value of the concept and conservatives affirming it. The debate has usually turned around its function or disfunction within apologetics or the philosophy of religion. The anti-supernaturalists have claimed that the concept seriously inhibits the conversation between Christianity and contemporary culture. The pro-supernaturalists have replied that, whatever its current cultural status, the supernatural is absolutely essential to Christianity. And any attempt to abandon it for apologetic or philosophical reasons would falsify the very meaning of the Christian message itself. The debate commonly ends there with both sides fixed in disagreement.

In The Retreat to Commitment (London, 1964), Professor W. W. Bartley III argues for a certain theory of rationality and contends that by this criterion it is not possible for a christian theist to be rational. His theory of rationality has already aroused considerable criticism, but his application of it to religious belief in particular, has not hitherto been widely considered.
