Right away this signifies a refusal to recognize any kind of living away from this world, or indeed taking the least interest in supramundane affairs.
All forms of religion, mysticism, magic, or the slightest hints of spiritual states must be resolutely rejected. Being begins with physical birth and terminates with death. Provided we stay within whatever bounds have been laid out by our “people-planners” our brief lives here may not be too bad. After all, we are only animals to be eaten up by earth when we are surplus on her surface. And so forth and so forth. The principle of all this is to divert us away from inherent divinity at all costs, whether by distracting attention, screening and obscuring viewpoints, or any other likely tactic.
People who are prepared to accept materialism as a way of living offer no opposition to intended evil or very much opportunity for intended good. So long as they willingly remain with their noses firmly glued to the ground their eyes are unlikely to discover any stars. They are no threat to evil doers at all. True, they may, and often do, draw distinct lines at physical or observable ills that might be traced to chemical and allied causes, but they will cheerfully allow all kinds of much more subtle and spiritually dangerous contaminants of consciousness first because they do not believe these have any reality, and then because they suppose that whatever will not respond to physical treatment can scarcely be much of a menace in a totally material world. The more humans who can be held as relatively happy captives of entirely greater opportunities earth bound environments, they occur for dedicated evil doers to operate on levels rather above the heads of those who refuse to up lift themselves beyond bodily bounds. In addition, if evil is intelligently presented as socially or economically expedient, it is incredible what materialists will not only accept, but actively insist upon. Perhaps the worst evil possible among materialists is to become convinced there is no such principle as evil at all. It has been said that the devil being the “father of lies”, his greatest deception has been to disguise himself from humanity altogether.
At all events, materialism might positively be marked up as a high major score for the “baddies” of life, whether incarnate or not. At a stroke, it reduces any serious opposition to their intentions right down to minimum. It may not provide over whelming possibilities of profit, but it does at least afford a definite work able basis in this world for whatever worst might be coming to it. By clever use of the powerful coercion compulsion persuaders to discourage man from seeing his divine spiritual heritage, humanity may remain condemned to the eventual extinction of all who refuse to rise above their material marks.
