“Like imperfect sleep which, instead of giving more strength to the head, doth but leave it the more exhausted, the result of mere operations of the imagination is but to weaken the soul. Instead of nourishment and energy she reaps only lassitude and disgust: whereas a genuine heavenly vision yields to her a harvest of ineffable spiritual riches, and an admirable renewal of bodily strength. I alleged these reasons to those who so often accused my visions of being the work of the enemy of mankind and the sport of my imagination.... I showed them the jewels which the divine hand had left with me:—they were my actual dispositions. All those who knew me saw that I was changed; my confessor bore witness to the fact; this improvement, palpable in all respects, far from being hidden, was brilliantly evident to all men. As for myself, it was impossible to believe that if the demon were its author, he could have used, in order to lose me and lead me to hell, an expedient so contrary to his own interests as that of uprooting my vices, and filling me with masculine courage and other virtues instead, for I saw clearly that a single one of these visions was enough to enrich me with all that wealth.”(6) I fear I may have made a longer excursus than was necessary, and that fewer words would have dispelled the uneasiness which may have arisen among some of you as I announced my pathological programme. At any rate you must all be ready now to judge the religious life by its results exclusively, and I shall assume that the bugaboo of morbid origin will scandalize your piety no more. Still, you may ask me, if its results are to be the ground of our final spiritual estimate of a religious phenomenon, why threaten us at all with so much existential study of its conditions? Why not simply leave pathological questions out? To this I reply in two ways: First, I say, irrepressible curiosity imperiously leads one on; and I say, secondly, that it always leads to a better understanding of a thing’s significance to consider its exaggerations and perversions, its equivalents and substitutes and nearest relatives elsewhere. Not that we may thereby swamp the thing in the wholesale condemnation which we pass on its inferior congeners, but rather that we may by contrast ascertain the more precisely in what its merits consist, by learning at the same time to what particular dangers of corruption it may also be exposed.
