To be sure, it makes our task difficult to have to deal so much with eccentricities and extremes. “How _can_ religion on the whole be the most important of all human functions,” you may ask, “if every several manifestation of it in turn have to be corrected and sobered down and pruned away?” Such a thesis seems a paradox impossible to sustain reasonably,—yet I believe that something like it will have to be our final contention. That personal attitude which the individual finds himself impelled to take up towards what he apprehends to be the divine—and you will remember that this was our definition—will prove to be both a helpless and a sacrificial attitude. That is, we shall have to confess to at least some amount of dependence on sheer mercy, and to practice some amount of renunciation, great or small, to save our souls alive. The constitution of the world we live in requires it:— “Entbehren sollst du! sollst entbehren! Das ist der ewige Gesang Der jedem an die Ohren klingt, Den, unser ganzes Leben lang Uns heiser jede Stunde singt.” For when all is said and done, we are in the end absolutely dependent on the universe; and into sacrifices and surrenders of some sort, deliberately looked at and accepted, we are drawn and pressed as into our only permanent positions of repose. Now in those states of mind which fall short of religion, the surrender is submitted to as an imposition of necessity, and the sacrifice is undergone at the very best without complaint. In the religious life, on the contrary, surrender and sacrifice are positively espoused: even unnecessary givings‐up are added in order that the happiness may increase. _Religion thus makes easy and felicitous what in any case is necessary_; and if it be the only agency that can accomplish this result, its vital importance as a human faculty stands vindicated beyond dispute. It becomes an essential organ of our life, performing a function which no other portion of our nature can so successfully fulfill. From the merely biological point of view, so to call it, this is a conclusion to which, so far as I can now see, we shall inevitably be led, and led moreover by following the purely empirical method of demonstration which I sketched to you in the first lecture. Of the farther office of religion as a metaphysical revelation I will say nothing now. But to foreshadow the terminus of one’s investigations is one thing, and to arrive there safely is another. In the next lecture, abandoning the extreme generalities which have engrossed us hitherto, I propose that we begin our actual journey by addressing ourselves directly to the concrete facts.
