And lastly, the very closeness with which modern experimental and analytical psychology is exploring the phenomena of our consciousness is once more bringing into ever-clearer relief the irrepressible metaphysical apprehensions and affirmations involved and implied by the experience of every human mind, from its first dim apprehension in infancy of a “something,” as yet undifferentiated by it into subjective and objective, up to its mature and reflective affirmation of the trans-subjective validity of its “positions,” or at least of its negations--pure scepticism turning out to be practically impossible. Here we have, with respect to that apprehension, such admirable workers as Henri Bergson in France, and Professors Henry Jones and James Ward in England; and, for this affirmation, such striking thinkers as the French Maurice Blondel, and the Germans Johannes Volkelt and Hugo Münsterberg. And Mgr. Mercier of Louvain, now Cardinal Mercier, has contributed some valuable criticism of certain points in these positions.[11] 5. _Difficulties of this inquiry._ Now here I am met at once by two special difficulties, the one personal to myself and to Catherine, and the other one of method. For, with regard to those three first sets of recent explorations of a psycho-physical kind, I am no physician at all, and not primarily a psychologist. And again, in Catherine’s instance, the evidence as to her psycho-physical states is not, as with St. Teresa and some few other cases, furnished by writings from the pen of the very person who experienced them, and it is at all copious and precise only for the period when she was admittedly ill and physically incapacitated.--And yet these last thirteen years of her life occupy a most prominent place in her biography; it is during, and on occasion of, those psycho-physical states, and largely with the materials furnished by them, that, precisely in those years, she built up her noblest legacy, her great Purgatorial teaching; the illness was (quite evidently) of a predominantly psychical type, and concerns more the psychologist than the physician, being closely connected with her particular temperament and type of spirituality, a temperament and type to be found again and again among the Saints. All this and more makes it simply impossible for me to shrink from some study of the matter, and permits me to hope for some success in attempting, slowly and cautiously, to arrive at certain general conclusions of a spiritually important kind.
