Such, then, is insight in general. But I am to speak of Religious Insight. Religious insight must be distinguished from other sorts of insight by its object, or by its various characteristic objects. Now, I have no time to undertake, in this opening discourse, any adequate definition of the term Religion or of the features that make an object a religious object. Religion has a long and complex history, and a tragic variety of forms and of objects of belief. And so religion varies prodigiously in its characteristics from age to age, from one portion of the human race to another, from one individual to another. If we permitted ourselves to define religion so as merely to insist upon what is common to all its forms, civilised and savage, our definition would tend to become so inclusive and so attenuated as to be almost useless for the purposes of the present brief inquiry. If, on the other hand, we defined religion so as to make the term denote merely what the believer in this or in that creed thinks of as his own religion, we should from the start cut ourselves off from the very breadth of view which I myself suppose to be essential to the highest sort of {8} religious Insight. Nobody fully comprehends what religion is who imagines that his own religion is the only genuine religion. As a fact, I shall therefore abandon at present the effort to give a technically finished definition of what constitutes religion, or of the nature of the religious objects. I shall here limit myself to a practically useful preliminary mention of a certain feature that, for my present purpose, shall be viewed as the essential characteristic of religion, and of religious objects, so far as these lectures propose to discuss religion. The higher religions of mankind--religions such as Buddhism and Christianity--have had in common this notable feature, namely, that they have been concerned with the problem of the Salvation of Man. This is sometimes expressed by saying that they are redemptive religions--religions interested in freeing mankind from some vast and universal burden, of imperfection, of unreasonableness, of evil, of misery, of fate, of unworthiness, or of sin. Now, for my present purposes, this _interest in the salvation of man_ shall be made, in these lectures, the essential feature of religion in so far as religion shall here be dealt with. The religious objects, whatever they otherwise may prove to be, shall be defined as objects such that, when we know them, and in case we can know them, this knowledge of them helps to show us the way of salvation. The central and essential postulate of whatever religion we, in these lectures, are to consider, is _the postulate that man {9} needs to be saved_. And religious insight shall for us mean insight into the way of salvation and into those objects whereof the knowledge conduces to salvation.
