nobody. Probably the same fate will attend the present pamphlet. A religion 

 which need not comprise the idea either of God or of personal immortality or of 

 morals will scarcely be received with enthusiasm by the dignitaries of the Church ; 

 and since we are informed that it is always non-scientific, we are perhaps absolved 

 rom offering any further criticism upon it. Hugh Elliot. 



The Master-Key : A new Philosophy addressed to Psychologists, Scientists, 

 Theologians, Christians, Jews, Agnostics, Spiritists, Ascetics, Orientalists, 

 and educated persons generally. By David Blair. [Pp. vi + 118.] 

 (Wimbledon : Ashrama Agency, 96, High Street, 1914.) 



The above title indicates the extensive audience to which this book is addressed. 

 We do not know what may be thought by the numerous categories of gentlemen 

 named above, to which we do not belong. But speaking for those one or two 

 categories to which we do belong, we must confess to a complete inability to 

 understand the author's meaning. Nine-tenths of the book is unintelligible ; and 

 the remaining tenth traverses every belief that we have been accustomed to hold. 

 Part I of the book, occupying six pages, settles the question of Man's Place in the 

 Universe. Part II deals with Life on Nature, whatever that may be. Part III 

 is Noumenoidal Life, which was such a terrifying name that we skipped it. Part IV 

 says that the first religion was closely connected with Fourth-sphere experience. 

 Never having had such an experience, we passed on to Part V, where, by 

 mischance, we landed straight in the middle of the Fourth Sphere again, and were 

 not much relieved on learning that " the worst things" living in this region "are 

 ugly and terrifying noumenoids." Fearful of meeting such a monster, we fled into 

 Part VI, which informed us that Jesus was a Jewish Buddha, "quite impossible 

 in Jewish Society," and that "Messianic Christianity" is "all moonshine." Part VII 

 brought us among the Ascetic philosophers, who certainly seem so disagreeable 

 that we were almost forced back upon the author's own philosophy of " Monadism." 

 But that philosophy we were still unable to comprehend. HUGH ELLIOT.
