In the psychologies and in the philosophies of religion, we find the authors attempting to specify just what entity it is. One man allies it to the feeling of dependence; one makes it a derivative from fear; others connect it with the sexual life; others still identify it with the feeling of the infinite; and so on. Such different ways of conceiving it ought of themselves to arouse doubt as to whether it possibly can be one specific thing; and the moment we are willing to treat the term “religious sentiment” as a collective name for the many sentiments which religious objects may arouse in alternation, we see that it probably contains nothing whatever of a psychologically specific nature. There is religious fear, religious love, religious awe, religious joy, and so forth. But religious love is only man’s natural emotion of love directed to a religious object; religious fear is only the ordinary fear of commerce, so to speak, the common quaking of the human breast, in so far as the notion of divine retribution may arouse it; religious awe is the same organic thrill which we feel in a forest at twilight, or in a mountain gorge; only this time it comes over us at the thought of our supernatural relations; and similarly of all the various sentiments which may be called into play in the lives of religious persons. As concrete states of mind, made up of a feeling _plus_ a specific sort of object, religious emotions of course are psychic entities distinguishable from other concrete emotions; but there is no ground for assuming a simple abstract “religious emotion” to exist as a distinct elementary mental affection by itself, present in every religious experience without exception. As there thus seems to be no one elementary religious emotion, but only a common storehouse of emotions upon which religious objects may draw, so there might conceivably also prove to be no one specific and essential kind of religious object, and no one specific and essential kind of religious act. ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ The field of religion being as wide as this, it is manifestly impossible that I should pretend to cover it. My lectures must be limited to a fraction of the subject. And, although it would indeed be foolish to set up an abstract definition of religion’s essence, and then proceed to defend that definition against all comers, yet this need not prevent me from taking my own narrow view of what religion shall consist in _for the purpose of these lectures_, or, out of the many meanings of the word, from choosing the one meaning in which I wish to interest you particularly, and proclaiming arbitrarily that when I say “religion” I mean _that_. This, in fact, is what I must do, and I will now preliminarily seek to mark out the field I choose.
