Inadequate knowledge of the human system includes the ranges and kinds of stimuli it can detect and the organs and corporeal, psychosomatic or electromagnetic instrumentalities, such as the body's field(s), by which external stimuli or variations in bodily or individual systemic conditions or states are 'registered'. Misconceptions and unverifiable assumptions remain an obstacle to human physical, mental, and emotional therapeutics as well as to education and to societal interactions.
The hypothesis that the head is the sole seat of intelligence is as unproven as the theory that the sole function of the heart is to pump blood, or that only the eyes see. In the last case, for example, seeing by the skin has been demonstrated. In various conditions of recovery from paralysis, and from brain and other injuries, assumptions concerning the brain and a brain-controlled nervous system have been challenged by the possibility of the distribution of 'intelligence' within the brain and to the spinal column, and perhaps to other internal organs. The phantom limb of amputees raises related questions concerning the body's subtle fields. Chinese acupuncture meridians and puncture or pressure points also indicate the extent of the unknown aspects of the body.
The body has still uninvestigated self-regulating and self-healing organs, unknown organs of knowledge and unknown organs that can effect action at a distance. Much of this has been repeatedly demonstrated. The extent or number of these faculties or organs argues that at least one other body may exist on a subtle material or energy level, and is the network or system out of which these higher faculties operate. In addition, these systems or sub-systems themselves may belong to a network, a noosphere in which each individual system is itself an organ. All the unknown organs of this macrocosmic body may constitute the essential unity of man that is not realized through the senses.
