The author's maiden adventure was the _Anoesthetic Revelation_, a pamphlet printed privately at Amsterdam in 1874. I forget how it fell into my hands, but it fascinated me so "weirdly" that I am conscious of its having been one of the stepping-stones of my thinking ever since. It gives the essence of Blood's philosophy, and shows most of the features of his talent--albeit one finds in it little humor and no verse. It is full of verbal felicity, felicity sometimes of precision, sometimes of metaphoric reach; it begins with dialectic reasoning, of an extremely Fichtean and Hegelian type, but it ends in a trumpet-blast of oracular mysticism, straight from the insight wrought by anaesthetics--of all things in the world--and unlike anything one ever heard before. The practically unanimous tradition of "regular" mysticism has been unquestionably _monistic_; and inasmuch as it is the characteristic of mystics to speak, not as the scribes, but as men who have "been there" and seen with their own eyes, I think that this sovereign manner must have made some other pluralistic-minded students hesitate, as I confess that it has often given pause to me. One cannot criticise the vision of a mystic--one can but pass it by, or else accept it as having some amount of evidential weight. I felt unable to do either with a good conscience until I met with Mr. Blood. His mysticism, which may, if one likes, be understood as monistic in this earlier utterance, develops in the later ones a sort of "left-wing" voice of defiance, and breaks into what to my ear has a radically pluralistic sound. I confess that the existence of this novel brand of mysticism has made my cowering mood depart. I feel now as if my own pluralism were not without the kind of support which mystical corroboration may confer. Morrison can no longer claim to be the only beneficiary of whatever right mysticism may possess to lend _prestige_. This is my philosophic, as distinguished from my literary, interest, in introducing Mr. Blood to this more fashionable audience: his philosophy, however mystical, is in the last resort not dissimilar from my own. I must treat him by "extracting" him, and simplify--certainly all too violently--as I extract. He is not consecutive as a writer, aphoristic and oracular rather; and being moreover sometimes dialectic, sometimes poetic, and sometimes mystic in his manner; sometimes monistic and sometimes pluralistic in his matter, I have to run my own risk in making him orate _pro domo mea_, and I am not quite unprepared to hear him say, in case he ever reads these pages, that I have entirely missed his point. No matter; I will proceed. I
