(1.) _Materialism_, the theory which regards mental phenomena as the product of molecular change in the brain; _i.e._, as the outcome of a transformation of motion into feeling (!). The cruder school once went so far as to identify mind with a “peculiar mode of motion” (!!), but this view is now happily regarded as absurd by most of the men of Science themselves. (2.)_ Monism_, or the Single Substance doctrine, is the more subtle form of negative psychology, which one of its advocates, Professor Bain, ably terms “guarded materialism.” This doctrine, which commands a very wide assent, counting among its upholders such men as Lewes, Spencer, Ferrier, and others, while positing thought and mental phenomena generally as radically contrasted with matter, regards them as the two sides, or aspects, of one and the same substance in some of its conditions. Thought as thought, they say, is utterly contrasted with material phenomena, but it must be also regarded as only “the subjective side of nervous motion”—whatever our learned men may mean by this. To return to the commentary on the Four Mahârâjahs, however, in the Egyptian temples, according to Clemens Alexandrinus, an immense curtain separated the tabernacle from the place for the congregation. The Jews had the same. In both, the curtain was drawn over five pillars (the Pentacle), symbolizing our five senses and five Root Races esoterically, while the four colours of the curtain represented the four cardinal points and the four terrestrial elements. The whole was an allegorical symbol. It is through the four high Rulers over the four points and elements that our five senses may become cognizant of the hidden truths of Nature; and not at all, as Clemens would have it, that it is the elements _per se_ that furnished the Pagans with Divine Knowledge or the Knowledge of God.(226) While the Egyptian emblem was spiritual, that of the Jews was purely materialistic, and, indeed, honoured only the blind elements and the imaginary “points.” For what was the meaning of the square Tabernacle raised by Moses in the wilderness, if it had not the same cosmical significance? “Thou shalt make an hanging ... of blue, purple, and scarlet ... five pillars of shittim wood for the hanging ... four brazen rings in the four corners thereof ... boards of fine wood for the four sides, North, South, West, and East ... of the Tabernacle ... with Cherubims of cunning work.”(227) The Tabernacle and the square courtyard, Cherubim and all, were precisely the same as those in the Egyptian temples. The square form of the Tabernacle meant just the same thing as it still means, to this day, in the exoteric worship of the Chinese and Tibetans—the four cardinal points signifying that which the four sides of the pyramids, obelisks, and other such square erections mean. Josephus takes care to explain the whole thing. He declares that the Tabernacle pillars were the same as those raised at Tyre to the four elements, which were placed on
