by a hopeless error: for any monthly rhythm in a woman must be sought by arranging her records according to her own menstrual month; and this menstrual month may vary in different women, from considerably less than a lunar month to thirty days or more.]
[375] I may add, however, that in my own case these discharges are—so far as I can trust my waking consciousness—frequently, if not usually, dreamless; and that strictly sexual dreams are extremely rare, notwithstanding the possession of a strongly emotional temperament.
[376] If I can trust my memory, I first experienced this discharge when a few months under fifteen years of age, and, if so, within a few weeks of the time when I was, in an instant, suddenly struck with the thought that possibly the religion in which I had been educated might be false. It is curiously interesting that the advent of puberty should have been heralded by this intellectual crisis.
[377] This unfortunate breach in the records was due to the fact that, failing to discover any regularity in, or law of, the occurrences of the discharges, I became discouraged and abandoned my records. In June, 1891, a re-examination of my pulse-records having led to my discovery of a lunar-monthly rhythm of the pulse, my interest in other physiological periodicities was reawakened, and I recommenced my records of these discharges.
[378] As a matter of fact, I take it that we may safely assert that no man who is content to be guided by his own instinctive cravings, and who neither suppresses these, on the one hand, nor endeavors to force himself, on the other hand, will be in any danger of erring by either excess or the contrary.
[379] [It is obvious that the opportunity of continuing such an inquiry as that described in this Appendix, ceases with marriage; but I may add (1906) that certain notes that I have kept with scrupulous exactness during eight years of married life, lend almost no support to the suggestion made in the text—i.e., that sexual desire is greater at one season of the year than at another. The nature of these notes I cannot discuss; but, they clearly indicate that, although there is a slight degree more of sexual desire in the second and third quarters of the year, than in the first and fourth, yet, this difference is so slight as to be almost negligible. Even if the months be rearranged in the triplets—November-December-January, etc.—so as to bring the maximum months of May, June, and July together, the difference between the highest quarter and the lowest amounts to an increase of only ten per cent, upon the latter—after allowing, of course, for the abnormal shortness of February; and, neglecting February, the increase in the maximum months (June and July) over the minimum (November) is equal to an increase of under 14 per cent, upon the latter. These differences are so vastly less than those shown on Chart VII that they possess almost no significance: but, lest too much stress be laid upon the apparently equalizing influence of married life, it must be added that the records discussed in the text were obtained during residence in London, whereas, since my marriage, I have lived in South Cornwall, where the climate is both milder and more equable.]

[381] I may add that the curve yielded by 1896–97 is remarkably parallel with that yielded by the preceding nine years, but I have not thought it worth while to chart these two additional curves.

[383] As will be observed, I have omitted the results of the incompletely recorded years of 1889 and 1891. The apparent explanation of this curious oscillation will be given directly.

APPENDIX C.
THE AUTO-EROTIC FACTOR IN RELIGION.
The intimate association between the emotions of love and religion is well known to all those who are habitually brought into close contact with the phenomena of the religious life. Love and religion are the two most volcanic emotions to which the human organism is liable, and it is not surprising that, when there is a disturbance in one of these spheres, the vibrations should readily extend to the other. Nor is it surprising that the two emotions should have a dynamic relation to each other, and that the auto-erotic impulse, being the more primitive and fundamental of the two impulses, should be able to pass its unexpended energy over to the religious emotion, there to find the expansion hitherto denied it, the love of the human becoming the love of the divine.
"I was not good enough for man,
And so am given to God."
Even when there is absolute physical suppression on the sexual side, it seems probable that thereby a greater intensity of spiritual fervor is caused. Many eminent thinkers seem to have been without sexual desire.
It is a noteworthy and significant fact that the age of love is also the age of conversion. Starbuck, for instance, in his very elaborate study of the psychology of conversion shows that the majority of conversions take place during the period of adolescence; that is, from the age of puberty to about 24 or 25.[385]
It would be easy to bring forward a long series of observations, from the most various points of view, to show the wide recognition of this close affinity between the sexual and the religious emotions. It is probable, as Hahn points out, that the connection between sexual suppression and religious rites, which we may trace at the very beginning of culture, was due to an instinctive impulse to heighten rather than abolish the sexual element. Early religious rites were largely sexual and orgiastic because they were largely an appeal to the generative forces of Nature to exhibit a beneficial productiveness. Among happily married people, as Hahn remarks, the sexual emotions rapidly give place to the cares and anxieties involved in supporting children; but when the exercise of the sexual function is prevented by celibacy, or even by castration, the most complete form of celibacy, the sexual emotions may pass into the psychical sphere to take on a more pronounced shape.[386] The early Christians adopted the traditional Eastern association between religion and celibacy, and, as the writings of the Fathers amply show, they expended on sexual matters a concentrated fervor of thought rarely known to the Greek and Roman writers of the best period.[387] As Christian theology developed, the minute inquisition into sexual things sometimes became almost an obsession. So far as I am aware, however (I cannot profess to have made any special investigation), it was not until the late Middle Ages that there is any clear recognition of the fact that, between the religious emotions and the sexual emotions, there is not only a superficial antagonism, but an underlying relationship. At this time so great a theologian and philosopher as Aquinas said that it is especially on the days when a man is seeking to make himself pleasing to God that the Devil troubles him by polluting him with seminal emissions. With somewhat more psychological insight, the wise old Knight
