Let me, to begin with, outline the main points of my paper.

First of all, I shall draw a very basic distinction between three parts or aspects of reality. I shall then go on to claim that there are certain kinds of understanding and explanation which correspond to each of these three parts, and to discuss the sort of experience these different kinds of understanding involve. Within this perspective, religion will emerge as one kind of understanding and explanation, different from and parallel to scientific understanding. Having reached this point in the argument, we shall be able to see one demarcation-line between scientific and religious understanding, and to offer one explanation why this demarcation-line is changing and culturally dependent. The next step, leading to Part II of my paper, claims that our attempt to understand our situation in the world involves the formation of an overall or ‘total’ view, an all-inclusive picture of reality. I shall then go on to discuss how the different kinds of understanding explained in Part I affect the formation of a total view. This leads to a classification of world-views into four main types, corresponding to the former distinctions. In this scheme, we see how religion can be a kind of understanding different from but dependent on that pointed out in Part I, and bearing a complicated relation to scientific understanding. In explaining this I shall also discuss the reasonableness of different world-views.
