It is with no small amount of trepidation that I take my place behind this desk, and face this learned audience. To us Americans, the experience of receiving instruction from the living voice, as well as from the books, of European scholars, is very familiar. At my own University of Harvard, not a winter passes without its harvest, large or small, of lectures from Scottish, English, French, or German representatives of the science or literature of their respective countries whom we have either induced to cross the ocean to address us, or captured on the wing as they were visiting our land. It seems the natural thing for us to listen whilst the Europeans talk. The contrary habit, of talking whilst the Europeans listen, we have not yet acquired; and in him who first makes the adventure it begets a certain sense of apology being due for so presumptuous an act. Particularly must this be the case on a soil as sacred to the American imagination as that of Edinburgh. The glories of the philosophic chair of this university were deeply impressed on my imagination in boyhood. Professor Fraser's Essays in Philosophy, then just published, was the first philosophic book I ever looked into, and I well remember the awestruck feeling I received from the account of Sir William Hamilton's classroom therein contained. Hamilton's own lectures were the first philosophic writings I ever forced myself to study, and after that I was immersed in Dugald Stewart and Thomas Brown. Such juvenile emotions of reverence never get outgrown; and I confess that to find my humble self promoted from my native wilderness to be actually for the time an official here, and transmuted into a colleague of these illustrious names, carries with it a sense of dreamland quite as much as of reality.
But since I have received the honor of this appointment I have felt that it would never do to decline. The academic career also has its heroic obligations, so I stand here without further deprecatory words. Let me say only this, that now that the current, here and at Aberdeen, has begun to run from west to east, I hope it may continue to do so. As the years go by, I hope that many of my countrymen may be asked to lecture in the Scottish universities, changing places with Scotsmen lecturing in the United States; I hope that our people may become in all these higher matters even as one people; and that the peculiar philosophic temperament, as well as the peculiar political temperament, that goes with our English speech may more and more pervade and influence the world.
As regards the manner in which I shall have to administer this lectureship, I am neither a theologian, nor a scholar learned in the history of religions, nor an anthropologist. Psychology is the only branch of learning in which I am particularly versed. To the psychologist the religious propensities of man must be at least as interesting as any other of the facts pertaining to his mental constitution. It would seem, therefore, that, as a psychologist, the natural thing for me would be to invite you to a descriptive survey of those religious propensities.
If the inquiry be psychological, not religious institutions, but rather religious feelings and religious impulses must be its subject, and I must confine myself to those more developed subjective phenomena recorded in literature produced by articulate and fully selfconscious men, in works of piety and autobiography. Interesting as the origins and early stages of a subject always are, yet when one seeks earnestly for its full significance, one must always look to its more completely evolved and perfect forms. It follows from this that the documents that will most concern us will be those of the men who were most accomplished in the religious life and best able to give an intelligible account of their ideas and motives. These men, of course, are either comparatively modern writers, or else such earlier ones as have become religious classics. The documents humains which we shall find most instructive need not then be sought for in the haunts of special erudition-they lie along the beaten highway; and this circumstance, which flows so naturally from the character of our problem, suits admirably also your lecturer's lack of special theological learning. I may take my citations, my sentences and paragraphs of personal confession, from books that most of you at some time will have had already in your hands, and yet this will be no detriment to the value of my conclusions. It is true that some more adventurous reader and investigator, lecturing here in future, may unearth from the shelves of libraries documents that will make a more delectable and curious entertainment to listen to than mine. Yet I doubt whether he will necessarily, by his control of so much more out-of-the-way material, get much closer to the essence of the matter in hand.
The question, What are the religious propensities? and the question, What is their philosophic significance? are two entirely different orders of question from the logical point of view; and, as a failure to recognize this fact distinctly may breed confusion, I wish to insist upon the point a little before we enter into the documents and materials to which I have referred.
In recent books on logic, distinction is made between two orders of inquiry concerning anything. First, what is the nature of it? how did it come about? what is its constitution, origin, and history? And second, What is its importance, meaning, or significance, now that it is once here? The answer to the one question is given in an existential judgment or proposition. The answer to the other is a proposition of value, what the Germans call a Werthurtheil, or what we may, if we like, denominate a spiritual judgment. Neither judgment can be deduced immediately from the other. They proceed from diverse intellectual preoccupations, and the mind combines them only by making them first separately, and then adding them together.
In the matter of religions it is particularly easy to distinguish the two orders of question. Every religious phenomenon has its history and its derivation from natural antecedents. What is nowadays called the higher criticism of the Bible is only a study of the Bible from this existential point of view, neglected too much by the earlier church. Under just what biographic conditions did the sacred writers bring forth their various contributions to the holy volume? And what had they exactly in their several individual minds, when they delivered their utterances? These are manifestly questions of historical fact, and one does not see how the answer to them can decide offhand the still further question: of what use should such a volume, with its manner of coming into existence so defined, be to us as a guide to life and a revelation? To answer this other question we must have already in our mind some sort of a general theory as to what the peculiarities in a thing should be which give it value for purposes of revelation; and this theory itself would be what I just called a spiritual judgment. Combining it with our existential judgment, we might indeed deduce another spiritual judgment as to the Bible's worth. Thus if our theory of revelation-value were to affirm that any book, to possess it, must have been composed automatically or not by the free caprice of the writer, or that it must exhibit no scientific and historic errors and express no local or personal passions, the Bible would probably fare ill at our hands. But if, on the other hand, our theory should allow that a book may well be a revelation in spite of errors and passions and deliberate human composition, if only it be a true record of the inner experiences of great-souled persons wrestling with the crises of their fate, then the verdict would be much more favorable. You see that the existential facts by themselves are insufficient for determining the value; and the best adepts of the higher criticism accordingly never confound the existential with the spiritual problem. With the same conclusions of fact before them, some take one view, and some another, of the Bible's value as a revelation, according as their spiritual judgment as to the foundation of values differs.
I make these general remarks about the two sorts of judgment, because there are many religious persons--some of you now present, possibly, are among them--who do not yet make a working use of the distinction, and who may therefore feel first a little startled at the purely existential point of view from which in the following lectures the phenomena of religious experience must be considered. When I handle them biologically and psychologically as if they were mere curious facts of individual history, some of you may think it a degradation of so sublime a subject, and may even suspect me, until my purpose gets more fully expressed, of deliberately seeking to discredit the religious side of life.
Such a result is of course absolutely alien to my intention; and since such a prejudice on your part would seriously obstruct the due effect of much of what I have to relate, I will devote a few more words to the point.
There can be no doubt that as a matter of fact a religious life, exclusively pursued, does tend to make the person exceptional and eccentric. I speak not now of your ordinary religious believer, who follows the conventional observances of his country, whether it be Buddhist, Christian, or Mohammedan. His religion has been made for him by others, communicated to him by tradition, determined to fixed forms by imitation, and retained by habit. It would profit us little to study this second-hand religious life. We must make search rather for the original experiences which were the pattern-setters to all this mass of suggested feeling and imitated conduct. These experiences we can only find in individuals for whom religion exists not as a dull habit, but as an acute fever rather. But such individuals are "geniuses" in the religious line; and like many other geniuses who have brought forth fruits effective enough for commemoration in the pages of biography, such religious geniuses have often shown symptoms of nervous instability. Even more perhaps than other kinds of genius, religious leaders have been subject to abnormal psychical visitations. Invariably they have been creatures of exalted emotional sensibility. Often they have led a discordant inner life, and had melancholy during a part of their career. They have known no measure, been liable to obsessions and fixed ideas; and frequently they have fallen into trances, heard voices, seen visions, and presented all sorts of peculiarities which are ordinarily classed as pathological. Often, moreover, these pathological features in their career have helped to give them their religious authority and influence.
If you ask for a concrete example, there can be no better one than is furnished by the person of George Fox. The Quaker religion which he founded is something which it is impossible to overpraise. In a day of shams, it was a religion of veracity rooted in spiritual inwardness, and a return to something more like the original gospel truth than men had ever known in England. So far as our Christian sects today are evolving into liberality, they are simply reverting in essence to the position which Fox and the early Quakers so long ago assumed. No one can pretend for a moment that in point of spiritual sagacity and capacity, Fox's mind was unsound. Everyone who confronted him personally, from Oliver Cromwell down to county magistrates and jailers, seems to have acknowledged his superior power. Yet from the point of view of his nervous constitution, Fox was a psychopath or detraque of the deepest dye. His Journal abounds in entries of this sort:--
"As I was walking with several friends, I lifted up my head and saw three steeple-house spires, and they struck at my life. I asked them what place that was? They said, Lichfield. Immediately the word of the Lord came to me, that I must go thither. Being come to the house we were going to, I wished the friends to walk into the house, saying nothing to them of whither I was to go. As soon as they were gone I stept away, and went by my eye over hedge and ditch till I came within a mile of Lichfield where, in a great field, shepherds were keeping their sheep. Then was I commanded by the Lord to pull off my shoes. I stood still, for it was winter: but the word of the Lord was like a fire in me. So I put off my shoes and left them with the shepherds; and the poor shepherds trembled, and were astonished. Then I walked on about a mile, and as soon as I was got within the city, the word of the Lord came to me again, saying: Cry, 'Wo to the bloody city of Lichfield!' So I went up and down the streets, crying with a loud voice, Wo to the bloody city of Lichfield! It being market day, I went into the market-place, and to and fro in the several parts of it, and made stands, crying as before, Wo to the bloody city of Lichfield! And no one laid hands on me. As I went thus crying through the streets, there seemed to me to be a channel of blood running down the streets, and the market-place appeared like a pool of blood. When I had declared what was upon me, and felt myself clear, I went out of the town in peace; and returning to the shepherds gave them some money, and took my shoes of them again. But the fire of the Lord was so on my feet, and all over me, that I did not matter to put on my shoes again, and was at a stand whether I should or no, till I felt freedom from the Lord so to do: then, after I had washed my feet, I put on my shoes again. After this a deep consideration came upon me, for what reason I should be sent to cry against that city, and call it The bloody city! For though the parliament had the minister one while, and the king another, and much blood had been shed in the town during the wars between them, yet there was no more than had befallen many other places. But afterwards I came to understand, that in the Emperor Diocletian's time a thousand Christians were martyr'd in Lichfield. So I was to go, without my shoes, through the channel of their blood, and into the pool of their blood in the market-place, that I might raise up the memorial of the blood of those martyrs, which had been shed above a thousand years before, and lay cold in their streets. So the sense of this blood was upon me, and I obeyed the word of the Lord."Bent as we are on studying religion's existential conditions, we cannot possibly ignore these pathological aspects of the subject.
We must describe and name them just as if they occurred in non-religious men. It is true that we instinctively recoil from seeing an object to which our emotions and affections are committed handled by the intellect as any other object is handled. The first thing the intellect does with an object is to class it along with something else. But any object that is infinitely important to us and awakens our devotion feels to us also as if it must be sui generis and unique. Probably a crab would be filled with a sense of personal outrage if it could hear us class it without ado or apology as a crustacean, and thus dispose of it. "I am no such thing, it would say; I am MYSELF, MYSELF alone.
The next thing the intellect does is to lay bare the causes in which the thing originates. Spinoza says: "I will analyze the actions and appetites of men as if it were a question of lines, of planes, and of solids." And elsewhere he remarks that he will consider our passions and their properties with the same eye with which he looks on all other natural things, since the consequences of our affections flow from their nature with the same necessity as it results from the nature of a triangle that its three angles should be equal to two right angles. Similarly M. Taine, in the introduction to his history of English literature, has written: "Whether facts be moral or physical, it makes no matter. They always have their causes. There are causes for ambition, courage, veracity, just as there are for digestion, muscular movement, animal heat. Vice and virtue are products like vitriol and sugar." When we read such proclamations of the intellect bent on showing the existential conditions of absolutely everything, we feel--quite apart from our legitimate impatience at the somewhat ridiculous swagger of the program, in view of what the authors are actually able to perform--menaced and negated in the springs of our innermost life. Such cold-blooded assimilations threaten, we think, to undo our soul's vital secrets, as if the same breath which should succeed in explaining their origin would simultaneously explain away their significance, and make them appear of no more preciousness, either, than the useful groceries of which M. Taine speaks.
Perhaps the commonest expression of this assumption that spiritual value is undone if lowly origin be asserted is seen in those comments which unsentimental people so often pass on their more sentimental acquaintances. Alfred believes in immortality so strongly because his temperament is so emotional. Fanny's extraordinary conscientiousness is merely a matter of overinstigated nerves. William's melancholy about the universe is due to bad digestion--probably his liver is torpid. Eliza's delight in her church is a symptom of her hysterical constitution. Peter would be less troubled about his soul if he would take more exercise in the open air, etc. A more fully developed example of the same kind of reasoning is the fashion, quite common nowadays among certain writers, of criticizing the religious emotions by showing a connection between them and the sexual life. Conversion is a crisis of puberty and adolescence. The macerations of saints, and the devotion of missionaries, are only instances of the parental instinct of self-sacrifice gone astray. For the hysterical nun, starving for natural life, Christ is but an imaginary substitute for a more earthly object of affection. And the like.
 As with many ideas that float in the air of one's time, this notion shrinks from dogmatic general statement and expresses itself only partially and by innuendo. It seems to me that few conceptions are less instructive than this re-interpretation of religion as perverted sexuality. It reminds one, so crudely is it often employed, of the famous Catholic taunt, that the Reformation may be best understood by remembering that its fons et origo was Luther's wish to marry a nun:--the effects are infinitely wider than the alleged causes, and for the most part opposite in nature. It is true that in the vast collection of religious phenomena, some are undisguisedly amatory--e.g., sex-deities and obscene rites in polytheism, and ecstatic feelings of union with the Savior in a few Christian mystics. But then why not equally call religion an aberration of the digestive function, and prove one's point by the worship of Bacchus and Ceres, or by the ecstatic feelings of some other saints about the Eucharist? Religious language clothes itself in such poor symbols as our life affords, and the whole organism gives overtones of comment whenever the mind is strongly stirred to expression. Language drawn from eating and drinking is probably as common in religious literature as is language drawn from the sexual life. We "hunger and thirst" after righteousness; we "find the Lord a sweet savor;" we "taste and see that he is good." "Spiritual milk for American babes, drawn from the breasts of both testaments," is a sub-title of the once famous New England Primer, and Christian devotional literature indeed quite floats in milk, thought of from the point of view, not of the mother, but of the greedy babe.
Saint Francois de Sales, for instance, thus describes the "orison of quietude": "In this state the soul is like a little child still at the breast, whose mother to caress him whilst he is still in her arms makes her milk distill into his mouth without his even moving his lips. So it is here. . . . Our Lord desires that our will should be satisfied with sucking the milk which His Majesty pours into our mouth, and that we should relish the sweetness without even knowing that it cometh from the Lord." And again: "Consider the little infants, united and joined to the breasts of their nursing mothers you will see that from time to time they press themselves closer by little starts to which the pleasure of sucking prompts them. Even so, during its orison, the heart united to its God oftentimes makes attempts at closer union by movements during which it presses closer upon the divine sweetness." Chemin de la Perfection, ch. xxxi.; Amour de Dieu, vii. ch. i.
In fact, one might almost as well interpret religion as a perversion of the respiratory function. The Bible is full of the language of respiratory oppression: "Hide not thine ear at my breathing; my groaning is not hid from thee; my heart panteth, my strength faileth me; my bones are hot with my roaring all the night long; as the hart panteth after the water-brooks, so my soul panteth after thee, O my God:" God's Breath in Man is the title of the chief work of our best known American mystic (Thomas Lake Harris), and in certain non-Christian countries the foundation of all religious discipline consists in regulation of the inspiration and expiration.
These arguments are as good as much of the reasoning one hears in favor of the sexual theory. But the champions of the latter will then say that their chief argument has no analogue elsewhere. The two main phenomena of religion, namely, melancholy and conversion, they will say, are essentially phenomena of adolescence, and therefore synchronous with the development of sexual life. To which the retort again is easy. Even were the asserted synchrony unrestrictedly true as a fact (which it is not), it is not only the sexual life, but the entire higher mental life which awakens during adolescence. One might then as well set up the thesis that the interest in mechanics, physics, chemistry, logic, philosophy, and sociology, which springs up during adolescent years along with that in poetry and religion, is also a perversion of the sexual instinct:--but that would be too absurd. Moreover, if the argument from synchrony is to decide, what is to be done with the fact that the religious age par excellence would seem to be old age, when the uproar of the sexual life is past?
The plain truth is that to interpret religion one must in the end look at the immediate content of the religious consciousness. The moment one does this, one sees how wholly disconnected it is in the main from the content of the sexual consciousness. Everything about the two things differs, objects, moods, faculties concerned, and acts impelled to. Any GENERAL assimilation is simply impossible: what we find most often is complete hostility and contrast. If now the defenders of the sex-theory say that this makes no difference to their thesis; that without the chemical contributions which the sex-organs make to the blood, the brain would not be nourished so as to carry on religious activities, this final proposition may be true or not true; but at any rate it has become profoundly uninstructive: we can deduce no consequences from it which help us to interpret religion's meaning or value. In this sense the religious life depends just as much upon the spleen, the pancreas, and the kidneys as on the sexual apparatus, and the whole theory has lost its point in evaporating into a vague general assertion of the dependence, SOMEHOW, of the mind upon the body.
We are surely all familiar in a general way with this method of discrediting states of mind for which we have an antipathy. We all use it to some degree in criticizing persons whose states of mind we regard as overstrained. But when other people criticize our own more exalted soul-flights by calling them 'nothing but' expressions of our organic disposition, we feel outraged and hurt, for we know that, whatever be our organism's peculiarities, our mental states have their substantive value as revelations of the living truth; and we wish that all this medical materialism could be made to hold its tongue.
Medical materialism seems indeed a good appellation for the too simple-minded system of thought which we are considering. Medical materialism finishes up Saint Paul by calling his vision on the road to Damascus a discharging lesion of the occipital cortex, he being an epileptic. It snuffs out Saint Teresa as an hysteric, Saint Francis of Assisi as an hereditary degenerate. George Fox's discontent with the shams of his age, and his pining for spiritual veracity, it treats as a symptom of a disordered colon. Carlyle's organ-tones of misery it accounts for by a gastro-duodenal catarrh. All such mental overtensions, it says, are, when you come to the bottom of the matter, mere affairs of diathesis (autointoxications most probably), due to the perverted action of various glands which physiology will yet discover. And medical materialism then thinks that the spiritual authority of all such personages is successfully undermined. For a first-rate example of medical-materialist reasoning, see an article on "les varietes du Type devot," by Dr. Binet-Sangle, in the Revue de l'Hypnotisme, xiv. 161.
Let us ourselves look at the matter in the largest possible way. Modern psychology, finding definite psycho-physical connections to hold good, assumes as a convenient hypothesis that the dependence of mental states upon bodily conditions must be thoroughgoing and complete. If we adopt the assumption, then of course what medical materialism insists on must be true in a general way, if not in every detail: Saint Paul certainly had once an epileptoid, if not an epileptic seizure; George Fox was an hereditary degenerate; Carlyle was undoubtedly auto-intoxicated by some organ or other, no matter which--and the rest. But now, I ask you, how can such an existential account of facts of mental history decide in one way or another upon their spiritual significance? According to the general postulate of psychology just referred to, there is not a single one of our states of mind, high or low, healthy or morbid, that has not some organic process as its condition. Scientific theories are organically conditioned just as much as religious emotions are; and if we only knew the facts intimately enough, we should doubtless see "the liver" determining the dicta of the sturdy atheist as decisively as it does those of the Methodist under conviction anxious about his soul. When it alters in one way the blood that percolates it, we get the methodist, when in another way, we get the atheist form of mind. So of all our raptures and our drynesses, our longings and pantings, our questions and beliefs. They are equally organically founded, be they religious or of non-religious content.
To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one has already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our DIS-beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of its possessor's body at the time.
It is needless to say that medical materialism draws in point of fact no such sweeping skeptical conclusion. It is sure, just as every simple man is sure, that some states of mind are inwardly superior to others, and reveal to us more truth, and in this it simply makes use of an ordinary spiritual judgment. It has no physiological theory of the production of these its favorite states, by which it may accredit them; and its attempt to discredit the states which it dislikes, by vaguely associating them with nerves and liver, and connecting them with names connoting bodily affliction, is altogether illogical and inconsistent.
Let us play fair in this whole matter, and be quite candid with ourselves and with the facts. When we think certain states of mind superior to others, is it ever because of what we know concerning their organic antecedents? No! it i
