One implication of the pneuminous theory is the solution to the problem of numerology (which is also the problem of many occult areas) i.e. how is it that a system with contingent associations (this number means this) make any sense at all? The answer is then that the accretion of the number functions by connecting pnueminous threads. So 4 is not just contingently the number of solidity, it is attached to this concept accretion literally in the pneuma. This is the phenomenological manifestation of the situation anyway.
