To be converted, to be regenerated, to receive grace, to experience religion, to gain an assurance, are so many phrases which denote the process, gradual or sudden, by which a self hitherto divided, and consciously wrong inferior and unhappy, becomes unified and consciously right superior and happy, in consequence of its firmer hold upon religious realities. This at least is what conversion signifies in general terms, whether or not we believe that a direct divine operation is needed to bring such a moral change about.
Before entering upon a minuter study of the process, let me enliven our understanding of the definition by a concrete example. I choose the quaint case of an unlettered man, Stephen H. Bradley, whose experience is related in a scarce American pamphlet.
 A sketch of the life of Stephen H. Bradley, from the age of five to twenty four years, including his remarkable experience of the power of the Holy Spirit on the second evening of November, 1829. Madison, Connecticut, 1830.
I select this case because it shows how in these inner alterations one may find one unsuspected depth below another, as if the possibilities of character lay disposed in a series of layers or shells, of whose existence we have no premonitory knowledge.Bradley thought that he had been already fully converted at the age of fourteen.
"I thought I saw the Saviour, by faith, in human shape, for about one second in the room, with arms extended, appearing to say to me, Come. The next day I rejoiced with trembling; soon after, my happiness was so great that I said that I wanted to die; this world had no place in my affections, as I knew of, and every day appeared as solemn to me as the Sabbath. I had an ardent desire that all mankind might feel as I did; I wanted to have them all love God supremely. Previous to this time I was very selfish and selfrighteous; but now I desired the welfare of all mankind, and could with a feeling heart forgive my worst enemies, and I felt as if I should be willing to bear the scoffs and sneers of any person, and suffer anything for His sake, if I could be the means in the hands of God, of the conversion of one soul."
Nine years later, in 1829, Mr. Bradley heard of a revival of religion that had begun in his neighborhood. "Many of the young converts," he says, "would come to me when in meeting and ask me if I had religion, and my reply generally was, I hope I have. This did not appear to satisfy them; they said they KNEW THEY had it. I requested them to pray for me, thinking with myself, that if I had not got religion now, after so long a time professing to be a Christian, that it was time I had, and hoped their prayers would be answered in my behalf.
"One Sabbath, I went to hear the Methodist at the Academy. He spoke of the ushering in of the day of general judgment; and he set it forth in such a solemn and terrible manner as I never heard before. The scene of that day appeared to be taking place, and so awakened were all the powers of my mind that, like Felix, I trembled involuntarily on the bench where I was sitting, though I felt nothing at heart. The next day evening I went to hear him again. He took his text from Revelation: 'And I saw the dead, small and great, stand before God.' And he represented the terrors of that day in such a manner that it appeared as if it would melt the heart of stone. When he finished his discourse, an old gentleman turned to me and said 'This is what I call preaching.' I thought the same, but my feelings were still unmoved by what he said, and I did not enjoy religion, but I believe he did.
"I will now relate my experience of the power of the Holy Spirit which took place on the same night. Had any person told me previous to this that I could have experienced the power of the Holy Spirit in the manner which I did, I could not have believed it, and should have thought the person deluded that told me so. I went directly home after the meeting, and when I got home I wondered what made me feel so stupid. I retired to rest soon after I got home, and felt indifferent to the things of religion until I began to be exercised by the Holy Spirit, which began in about five minutes after, in the following manner:--
"At first, I began to feel my heart beat very quick all on a sudden, which made me at first think that perhaps something is going to ail me, though I was not alarmed, for I felt no pain. My heart increased in its beating, which soon convinced me that it was the Holy Spirit from the effect it had on me. I began to feel exceedingly happy and humble, and such a sense of unworthiness as I never felt before. I could not very well help speaking out, which I did, and said, Lord, I do not deserve this happiness, or words to that effect, while there was a stream (resembling air in feeling) came into my mouth and heart in a more sensible manner than that of drinking anything, which continued, as near as I could judge, five minutes or more, which appeared to be the cause of such a palpitation of my heart. It took complete possession of my soul, and I am certain that I desired the Lord, while in the midst of it, not to give me any more happiness, for it seemed as if I could not contain what I had got. My heart seemed as if it would burst, but it did not stop until I felt as if I was unutterably full of the love and grace of God. In the mean time while thus exercised, a thought arose in my mind, what can it mean? and all at once, as if to answer it, my memory became exceedingly clear, and it appeared to me just as if the New Testament was placed open before me, eighth chapter of Romans, and as light as if some candle lighted was held for me to read the 26th and 27th verses of that chapter, and I read these words: 'The Spirit helpeth our infirmities with groanings which cannot be uttered.' And all the time that my heart was a-beating, it made me groan like a person in distress, which was not very easy to stop, though I was in no pain at all, and my brother being in bed in another room came and opened the door, and asked me if I had got the toothache. I told him no, and that he might get to sleep. I tried to stop. I felt unwilling to go to sleep myself, I was so happy, fearing I should lose it-- thinking within myself'My willing soul would stay In such a frame as this.'
And while I lay reflecting, after my heart stopped beating, feeling as if my soul was full of the Holy Spirit, I thought that perhaps there might be angels hovering round my bed. I felt just as if I wanted to converse with them, and finally I spoke, saying 'O ye affectionate angels! how is it that ye can take so much interest in our welfare, and we take so little interest in our own.' After this, with difficulty I got to sleep; and when I awoke in the morning my first thoughts were: What has become of my happiness? and, feeling a degree of it in my heart, I asked for more, which was given to me as quick as thought. I then got up to dress myself, and found to my surprise that I could but just stand. It appeared to me as if it was a little heaven upon earth. My soul felt as completely raised above the fears of death as of going to sleep; and like a bird in a cage, I had a desire, if it was the will of God, to get released from my body and to dwell with Christ, though willing to live to do good to others, and to warn sinners to repent. I went downstairs feeling as solemn as if I had lost all my friends, and thinking with myself, that I would not let my parents know it until I had first looked into the Testament. I went directly to the shelf and looked into it, at the eighth of Romans, and every verse seemed to almost speak and to confirm it to be truly the Word of God, and as if my feelings corresponded with the meaning of the word. I then told my parents of it, and told them that I thought that they must see that when I spoke, that it was not my own voice, for it appeared so to me. My speech seemed entirely under the control of the Spirit within me; I do not mean that the words which I spoke were not my own, for they were. I thought that I was influenced similar to the Apostles on the day of Pentecost (with the exception of having power to give it to others, and doing what they did). After breakfast I went round to converse with my neighbors on religion, which I could not have been hired to have done before this, and at their request I prayed with them, though I had never prayed in public before.
"I now feel as if I had discharged my duty by telling the truth, and hope by the blessing of God, it may do some good to all who shall read it. He has fulfilled his promise in sending the Holy Spirit down into our hearts, or mine at least, and I now defy all the Deists and Atheists in the world to shake my faith in Christ."
So much for Mr. Bradley and his conversion, of the effect of which upon his later life we gain no information. Now for a minuter survey of the constituent elements of the conversion process.
If you open the chapter on Association, of any treatise on Psychology, you will read that a man's ideas, aims, and objects form diverse internal groups and systems, relatively independent of one another. Each 'aim' which he follows awakens a certain specific kind of interested excitement, and gathers a certain group of ideas together in subordination to it as its associates; and if the aims and excitements are distinct in kind, their groups of ideas may have little in common. When one group is present and engrosses the interest, all the ideas connected with other groups may be excluded from the mental field. The President of the United States when, with paddle, gun, and fishing-rod, he goes camping in the wilderness for a vacation, changes his system of ideas from top to bottom. The presidential anxieties have lapsed into the background entirely; the official habits are replaced by the habits of a son of nature, and those who knew the man only as the strenuous magistrate would not "know him for the same person" if they saw him as the camper.
If now he should never go back, and never again suffer political interests to gain dominion over him, he would be for practical intents and purposes a permanently transformed being. Our ordinary alterations of character, as we pass from one of our aims to another, are not commonly called transformations, because each of them is so rapidly succeeded by another in the reverse direction; but whenever one aim grows so stable as to expel definitively its previous rivals from the individual's life, we tend to speak of the phenomenon, and perhaps to wonder at it, as a "transformation."
These alternations are the completest of the ways in which a self may be divided. A less complete way is the simultaneous coexistence of two or more different groups of aims, of which one practically holds the right of way and instigates activity, whilst the others are only pious wishes, and never practically come to anything. Saint Augustine's aspirations to a purer life, in our last lecture, were for a while an example. Another would be the President in his full pride of office, wondering whether it were not all vanity, and whether the life of a wood-chopper were not the wholesomer destiny. Such fleeting aspirations are mere velleitates, whimsies. They exist on the remoter outskirts of the mind, and the real self of the man, the centre of his energies, is occupied with an entirely different system. As life goes on, there is a constant change of our interests, and a consequent change of place in our systems of ideas, from more central to more peripheral, and from more peripheral to more central parts of consciousness. I remember, for instance, that one evening when I was a youth, my father read aloud from a Boston newspaper that part of Lord Gifford's will which founded these four lectureships. At that time I did not think of being a teacher of philosophy, and what I listened to was as remote from my own life as if it related to the planet Mars. Yet here I am, with the Gifford system part and parcel of my very self, and all my energies, for the time being, devoted to successfully identifying myself with it. My soul stands now planted in what once was for it a practically unreal object, and speaks from it as from its proper habitat and centre.
When I say "Soul," you need not take me in the ontological sense unless you prefer to; for although ontological language is instinctive in such matters, yet Buddhists or Humians can perfectly well describe the facts in the phenomenal terms which are their favorites. For them the soul is only a succession of fields of consciousness: yet there is found in each field a part, or sub-field, which figures as focal and contains the excitement, and from which, as from a centre, the aim seems to be taken. Talking of this part, we involuntarily apply words of perspective to distinguish it from the rest, words like "here," "this," "now," "mine," or "me"; and we ascribe to the other parts the positions "there," "then," "that," "his" or "thine," "it," "not me." But a "here" can change to a "there," and a "there" become a "here," and what was "mine" and what was "not mine" change their places.
What brings such changes about is the way in which emotional excitement alters. Things hot and vital to us to-day are cold to-morrow. It is as if seen from the hot parts of the field that the other parts appear to us, and from these hot parts personal desire and volition make their sallies. They are in short the centres of our dynamic energy, whereas the cold parts leave us indifferent and passive in proportion to their coldness.
Whether such language be rigorously exact is for the present of no importance. It is exact enough, if you recognize from your own experience the facts which I seek to designate by it.
Now there may be great oscillation in the emotional interest, and the hot places may shift before one almost as rapidly as the sparks that run through burnt-up paper. Then we have the wavering and divided self we heard so much of in the previous lecture. Or the focus of excitement and heat, the point of view from which the aim is taken, may come to lie permanently within a certain system; and then, if the change be a religious one, we call it a CONVERSION, especially if it be by crisis, or sudden.
Let us hereafter, in speaking of the hot place in a man's consciousness, the group of ideas to which he devotes himself, and from which he works, call it THE HABITUAL CENTRE OF HIS PERSONAL ENERGY. It makes a great difference to a man whether one set of his ideas, or another, be the centre of his energy; and it makes a great difference, as regards any set of ideas which he may possess, whether they become central or remain peripheral in him. To say that a man is "converted" means, in these terms, that religious ideas, previously peripheral in his consciousness, now take a central place, and that religious aims form the habitual centre of his energy.
Now if you ask of psychology just HOW the excitement shifts in a man's mental system, and WHY aims that were peripheral become at a certain moment central, psychology has to reply that although she can give a general description of what happens, she is unable in a given case to account accurately for all the single forces at work. Neither an outside observer nor the Subject who undergoes the process can explain fully how particular experiences are able to change one's centre of energy so decisively, or why they so often have to bide their hour to do so. We have a thought, or we perform an act, repeatedly, but on a certain day the real meaning of the thought peals through us for the first time, or the act has suddenly turned into a moral impossibility. All we know is that there are dead feelings, dead ideas, and cold beliefs, and there are hot and live ones; and when one grows hot and alive within us, everything has to re-crystallize about it. We may say that the heat and liveliness mean only the "motor efficacy," long deferred but now operative, of the idea; but such talk itself is only circumlocution, for whence the sudden motor efficacy? And our explanations then get so vague and general that one realizes all the more the intense individuality of the whole phenomenon.
In the end we fall back on the hackneyed symbolism of a mechanical equilibrium. A mind is a system of ideas, each with the excitement it arouses, and with tendencies impulsive and inhibitive, which mutually check or reinforce one another. The collection of ideas alters by subtraction or by addition in the course of experience, and the tendencies alter as the organism gets more aged. A mental system may be undermined or weakened by this interstitial alteration just as a building is, and yet for a time keep upright by dead habit. But a new perception, a sudden emotional shock, or an occasion which lays bare the organic alteration, will make the whole fabric fall together; and then the centre of gravity sinks into an attitude more stable, for the new ideas that reach the centre in the rearrangement seem now to be locked there, and the new structure remains permanent.
Formed associations of ideas and habits are usually factors of retardation in such changes of equilibrium. New information, however acquired, plays an accelerating part in the changes; and the slow mutation of our instincts and propensities, under the "unimaginable touch of time" has an enormous influence. Moreover, all these influences may work subconsciously or half unconsciously. And when you get a Subject in whom the subconscious life--of which I must speak more fully soon--is largely developed, and in whom motives habitually ripen in silence, you get a case of which you can never give a full account, and in which, both to the Subject and the onlookers, there may appear an element of marvel. Emotional occasions, especially violent ones, are extremely potent in precipitating mental rearrangements. The sudden and explosive ways in which love, jealousy, guilt, fear, remorse, or anger can seize upon one are known to everybody. Hope, happiness, security, resolve, emotions characteristic of conversion, can be equally explosive. And emotions that come in this explosive way seldom leave things as they found them.
 Jouffroy is an example: "Down this slope it was that my intelligence had glided, and little by little it had got far from its first faith. But this melancholy revolution had not taken place in the broad daylight of my consciousness; too many scruples, too many guides and sacred affections had made it dreadful to me, so that I was far from avowing to myself the progress it had made. It had gone on in silence, by an involuntary elaboration of which I was not the accomplice; and although I had in reality long ceased to be a Christian, yet, in the innocence of my intention, I should have shuddered to suspect it, and thought it calumny had I been accused of such a falling away." Then follows Jouffroy's account of his counter-conversion, quoted above on p. 173.
 One hardly needs examples; but for love, see p. 176, note, for fear, p. 161 ; for remorse, see Othello after the murder; for anger see Lear after Cordelia's first speech to him; for resolve, see p. 175 (J. Foster case). Here is a pathological case in which GUILT was the feeling that suddenly exploded: "One night I was seized on entering bed with a rigor, such as Swedenborg describes as coming over him with a sense of holiness, but over me with a sense of GUILT. During that whole night I lay under the influence of the rigor, and from its inception I felt that I was under the curse of God. I have never done one act of duty in my life--sins against God and man beginning as far as my memory goes back--a wildcat in human shape."
In his recent work on the Psychology of Religion, Professor Starbuck of California has shown by a statistical inquiry how closely parallel in its manifestations the ordinary "conversion" which occurs in young people brought up in evangelical circles is to that growth into a larger spiritual life which is a normal phase of adolescence in every class of human beings. The age is the same, falling usually between fourteen and seventeen. The symptoms are the same,--sense of incompleteness and imperfection; brooding, depression, morbid introspection, and sense of sin; anxiety about the hereafter; distress over doubts, and the like. And the result is the same--a happy relief and objectivity, as the confidence in self gets greater through the adjustment of the faculties to the wider outlook. In spontaneous religious awakening, apart from revivalistic examples, and in the ordinary storm and stress and moulting-time of adolescence, we also may meet with mystical experiences, astonishing the subjects by their suddenness, just as in revivalistic conversion. The analogy, in fact, is complete; and Starbuck's conclusion as to these ordinary youthful conversions would seem to be the only sound one: Conversion is in its essence a normal adolescent phenomenon, incidental to the passage from the child's small universe to the wider intellectual and spiritual life of maturity.
"Theology," says Dr. Starbuck, "takes the adolescent tendencies and builds upon them; it sees that the essential thing in adolescent growth is bringing the person out of childhood into the new life of maturity and personal insight. It accordingly brings those means to bear which will intensify the normal tendencies. It shortens up the period of duration of storm and stress." The conversion phenomena of "conviction of sin" last, by this investigator's statistics, about one fifth as long as the periods of adolescent storm and stress phenomena of which he also got statistics, but they are very much more intense. Bodily accompaniments, loss of sleep and appetite, for example, are much more frequent in them. "The essential distinction appears to be that conversion intensifies but shortens the period by bringing the person to a definite crisis." E. D. Starbuck: The Psychology of Religion, pp. 224, 262.
The conversions which Dr. Starbuck here has in mind are of course mainly those of very commonplace persons, kept true to a pre-appointed type by instruction, appeal, and example. The particular form which they affect is the result of suggestion and imitation. If they went through their growth-crisis in other faiths and other countries, although the essence of the change would be the same (since it is one in the main so inevitable), its accidents would be different. In Catholic lands, for example, and in our own Episcopalian sects, no such anxiety and conviction of sin is usual as in sects that encourage revivals. The sacraments being more relied on in these more strictly ecclesiastical bodies, the individual's personal acceptance of salvation needs less to be accentuated and led up to.
 No one understands this better than Jonathan Edwards understood it already. Conversion narratives of the more commonplace sort must always be taken with the allowances which he suggests:
"A rule received and established by common consent has a very great, though to many persons an insensible influence in forming their notions of the process of their own experience. I know very well how they proceed as to this matter, for I have had frequent opportunities of observing their conduct. Very often their experience at first appears like a confused chaos, but then those parts are selected which bear the nearest resemblance to such particular steps as are insisted on; and these are dwelt upon in their thoughts, and spoken of from time to time, till they grow more and more conspicuous in their view, and other parts which are neglected grow more and more obscure. Thus what they have experienced is insensibly strained, so as to bring it to an exact conformity to the scheme already established in their minds. And it becomes natural also for ministers, who have to deal with those who insist upon distinctness and clearness of method, to do so too." Treatise on Religious Affections.
But every imitative phenomenon must once have had its original, and I propose that for the future we keep as close as may be to the more first-hand and original forms of experience. These are more likely to be found in sporadic adult cases.
Professor Leuba, in a valuable article on the psychology of conversion, subordinates the theological aspect of the religious life almost entirely to its moral aspect. The religious sense he defines as "the feeling of unwholeness, of moral imperfection, of sin, to use the technical word, accompanied by the yearning after the peace of unity." "The word 'religion,'" he says, "is getting more and more to signify the conglomerate of desires and emotions springing from the sense of sin and its release"; and he gives a large number of examples, in which the sin ranges from drunkenness to spiritual pride, to show that the sense of it may beset one and crave relief as urgently as does the anguish of the sickened flesh or any form of physical misery. Studies in the Psychology of Religious Phenomena, American Journal of Psychology, vii. 309 (1896).
Undoubtedly this conception covers an immense number of cases. A good one to use as an example is that of Mr. S. H. Hadley, who after his conversion became an active and useful rescuer of drunkards in New York. His experience runs as follows:--
"One Tuesday evening I sat in a saloon in Harlem, a homeless, friendless, dying drunkard. I had pawned or sold everything that would bring a drink. I could not sleep unless I was dead drunk. I had not eaten for days, and for four nights preceding I had suffered with delirium tremens, or the horrors, from midnight till morning. I had often said, 'I will never be a tramp. I will never be cornered, for when that time comes, if ever it comes, I will find a home in the bottom of the river.' But the Lord so ordered it that when that time did come I was not able to walk one quarter of the way to the river. As I sat there thinking, I seemed to feel some great and mighty presence. I did not know then what it was. I did learn afterwards that it was Jesus, the sinner's friend. I walked up to the bar and pounded it with my fist till I made the glasses rattle. Those who stood by drinking looked on with scornful curiosity. I said I would never take another drink, if I died on the street, and really I felt as though that would happen before morning. Something said, 'If you want to keep this promise, go and have yourself locked up.' I went to the nearest station-house and had myself locked up.
"I was placed in a narrow cell, and it seemed as though all the demons that could find room came in that place with me. This was not all the company I had, either. No, praise the Lord: that dear Spirit that came to me in the saloon was present, and said, Pray. I did pray, and though I did not feel any great help, I kept on praying. As soon as I was able to leave my cell I was taken to the police court and remanded back to the cell. I was finally released, and found my way to my brother's house, where every care was given me. While lying in bed the admonishing Spirit never left me, and when I arose the following Sabbath morning I felt that day would decide my fate, and toward evening it came into my head to go to Jerry M'Auley's Mission. I went. The house was packed, and with great difficulty I made my way to the space near the platform. There I saw the apostle to the drunkard and the outcast--that man of God, Jerry M'Auley. He rose, and amid deep silence told his experience. There was a sincerity about this man that carried conviction with it, and I found myself saying, 'I wonder if God can save me?' I listened to the testimony of twenty-five or thirty persons, every one of whom had been saved from rum, and I made up my mind that I would be saved or die right there. When the invitation was given, I knelt down with a crowd of drunkards. Jerry made the first prayer. Then Mrs. M'Auley prayed fervently for us. Oh, what a conflict was going on for my poor soul! A blessed whisper said, 'Come'; the devil said, 'Be careful.' I halted but a moment, and then, with a breaking heart, I said, 'Dear Jesus, can you help me?' Never with mortal tongue can I describe that moment. Although up to that moment my soul had been filled with indescribable gloom, I felt the glorious brightness of the noonday sun shine into my heart. I felt I was a free man. Oh, the precious feeling of safety, of freedom, of resting on Jesus! I felt that Christ with all his brightness and power had come into my life; that, indeed, old things had passed away and all things had become new.
"From that moment till now I have never wanted a drink of whiskey, and I have never seen money enough to make me take one. I promised God that night that if he would take away the appetite for strong drink, I would work for him all my life. He has done his part, and I have been trying to do mine."
 I have abridged Mr. Hadley's account. For other conversions of drunkards, see his pamphlet, Rescue Mission Work, published at the Old Jerry M'Auley Water Street Mission, New York City. A striking collection of cases also appears in the appendix to Professor Leuba's article.
<200> Dr. Leuba rightly remarks that there is little doctrinal theology in such an experience, which starts with the absolute need of a higher helper, and ends with the sense that he has helped us. He gives other cases of drunkards' conversions which are purely ethical, containing, as recorded, no theological beliefs whatever. John B. Gough's case, for instance, is practically, says Dr. Leuba, the conversion of an atheist--neither God nor Jesus being mentioned. But in spite of the importance of this type of regeneration, with little or no intellectual readjustment, this writer surely makes it too exclusive. It corresponds to the subjectively centered form of morbid melancholy, of which Bunyan and Alline were examples. But we saw in our seventh lecture that there are objective forms of melancholy also, in which the lack of rational meaning of the universe, and of life anyhow, is the burden that weighs upon one--you remember Tolstoy's case. So there are distinct elements in conversion, and their relations to individual lives deserve to be discriminated.
 A restaurant waiter served provisionally as Gough's 'Saviour.' General Booth, the founder of the Salvation Army, considers that the first vital step in saving outcasts consists in making them feel that some decent human being cares enough for them to take an interest in the question whether they are to rise or sink.
 The crisis of apathetic melancholy--no use in life--into which J. S. Mill records that he fell, from which he emerged by the reading of Marmontel's Memoirs (Heaven save the mark!) and Wordsworth's poetry, is another intellectual and general metaphysical case. See Mill's Autobiography, New York, 1873, pp. 141, 148. Starbuck, in addition to "escape from sin," discriminates "spiritual illumination" as a distinct type of conversion experience. Psychology of Religion, p. 85.
Some persons, for instance, never are, and possibly never under any circumstances could be, converted. Religious ideas cannot become the centre of their spiritual energy. They may be excellent persons, servants of God in practical ways, but they are not children of his kingdom. They are either incapable of imagining the invisible; or else, in the language of devotion, they are life-long subjects of "barrenness" and "dryness." Such inaptitude for religious faith may in some cases be intellectual
