The Exquisite Symmetry
Human Biology & the Enneagram
The Enneagram is remarkable in the elegance of its overall symmetry and internal unity. In this essay I wish to examine both the internal unity as well as the symmetry, both in light of the unifying principles of human biology. The Enneagram describes the psychological state of the human condition while human biology describes the physiologic state of the human organism. Without both functioning optimally, the organism’s survival is in jeopardy.
Diversity and Unity are dominant themes within both the Enneagram and Biology. Both are ways, or processes, of understanding the world. Biologists estimate up to 30 million different species existing on Earth, each uniquely different and differentiable, yet each displaying characteristics common to all. Just as there exists an abundance of tested predictions, and accepted explanations for Human Biology; so also does the remarkable abundance of information contained within the Enneagram describe dynamic movement of human psychological behavior.
Evolution has unfolded over millions of years resulting in these exquisite supportive processes, accessible in humans as flexible, dynamic, and essential capacities. The dynamism of the Enneagram is directly parallel to the dynamism of Biology.
The basic human physiologic principle of homeostasis is defined as the maintenance of a stable internal environment in spite of what may be a very different external environment. As a description of the human psychological condition (addressing instinctive, mental, and emotional drives) the Enneagram mirrors and supports the basic survival of the human organism just as profoundly as do well described physiologic mechanisms. The survival of the individual is dependent upon maintaining homeostasis in both of these arenas of life. Human physiology achieves this by means of negative feedback loops, regulatory mechanisms that slow down or shut down output systems when they reach certain levels that threaten the stability of the organism’s internal environment. The Enneagram describes the same processes affecting behavior. Without these pop off valves the health of the organism is threatened.
An everyday example of an unconscious stabilizing feedback loop in humans is the physiologic mechanism to lower body temperature, a mechanism triggered when the internal body temperature rises above certain critical levels. Likewise, when psychological functioning is stressed, the Enneagram illuminates how we unconsciously shunt over to behaviors along our Lines of Flow to stabilize our psychological self.
It is important to keep in mind that these responses to an upset of homeostasis are carried out unconsciously- both physiologically and psychologically. One does not need to ‘tell’ the body to initiate thermoregulatory responses in the event of high fever just as an individual dominant in Type Two does not ‘tell’ herself to ‘go to Eight’ in order to avoid decompensating down the levels and risk behaving in a manner which in some degree may prove self-destructive.
When thermoregulatory mechanisms are triggered, the internal body temperature falls, thus protecting cells from thermal damage. The existing state which initiated the fever to begin with may well still persist, for instance an infection, but this lowering of dangerously high temperature assists the body in preserving key physiologic functioning in order to better cope with the threat of infection.
The Enneagram Lines of Flow do exactly the same thing, even if this effect cannot be easily quantified in a test tube or via a thermometer measurement. A clear example is that of a Type Nine individual who is deteriorating down to the stubborn and stonewalling behaviors of the lower ‘Average Level.’ If, with the ongoing stress to the system, the Type Nine man did not shunt over to the average behaviors of the Type Six along the Inner Triangle of Flow, he might cross the shock point, ‘build a moat to keep others out,’ and deteriorate down into the Unhealthy Levels where he would stand in violation to himself as well as others. This behavior could look suspicious, authoritarian, and short-tempered which in itself isn’t particularly attractive, but non-the-less he avoids falling into ineffectual, neglectful, and willfully blind behaviors. Here in the Type Six, still Average Level, he retains the capacity for insight into his behavior and the opportunity to right himself, gain a foothold, and move back up to healthier behaviors.
If you have ever experienced the lysis of fever consisting of shaking chills and profuse sweating, you would physically be experiencing the internal unconscious shunting to thermoregualtory mechanisms to right your physiology, i.e. maintain homeostasis. While it isn’t pleasant to experience or to witness a rigor, it serves the purpose of preventing an individual from slipping into fever induced seizures (convulsions) or even coma. It also prevents permanent cell death in the brain as well as other organs. We, both psychologically and physiologically, shunt to preserve our core dynamics and from there we have the opportunity for recovery.
There is a beautiful symmetry here: a symmetry of biologic and psychologic processes responding in a dynamic fashion to stresses put upon the human organism- temperature righting itself; behavior stabilizing itself. Both promote survival.
One could give examples of any and all organ systems within the human body, from the concentration of urine when we thirst, to the shift of our hemoglobin’s capacity to transport oxygen at high altitude.
Likewise, psychological systems respond similarly as for example the same Type Six individual who finds himself fending off panic and paralysis concentrates his outward production of energy by moving into action oriented Type Three behaviors or a Type Eight woman who is on the verge of a huge physical outburst turns inward and retreats to a time and space of lone quiet.
The elegance is breathtaking in all its symmetrical detail and its dazzling support of the survival and growth of the human potential. Just as we can predict biologic response, so too can we predict psychologically driven behavior. Awareness is the key.
I propose that if the Enneagram wisdom could be viewed by Science as just as deserving of exploration, study, and analysis as human biology, man as a species would have far better tools in service of ultimate survival.
