Abstract
This paper is devoted to the task of exploring just what there is in man's nature which makes it possible for him to be open to religious experience, to be positively disposed to receive it. By ‘natural’ here I mean only that which all men are in fact endowed with when they enter this present world of human history before they enter into any particular religious context. Hence I am not going to get involved in the difficult theological controversy as to whether this initial endowment includes only what is due to human nature as a created nature or also some supernatural extra gift of God as orienting man in a special way towards himself in this existential historical order, which could have been otherwise. What he begins life with in the present historical order I shall call natural, whatever its origin.What I mean by ‘religious experience’ must be left somewhat vague, so as to include its many varieties. Let us describe it roughly as any direct existential awareness of the presence or activity of an ultimate, absolute, transcendent dimension of reality, especially the more intense forms of unitive awareness of this Transcendent which have traditionally been called ‘mystical experience’. Before beginning our exploration, let me stress that my purpose here is not to establish or validate that there is such a thing as authentic religious experience. I presuppose that as known or accepted from elsewhere, at least as a hypothesis for discussion
