Instincts – Self Preservation, Social, Sexual.These three instincts are built into our bestial nature, which resides at an unconscious level helping to ensure our survival, both of ourselves and our species. From the perspective of the enneagram, we want to know how these drives appear and function, both within personality and as distinct patterns, as defined by each instinct alone or the alignment of two or three (stacking).
Sexuals attract others without really trying. They also repel others in the same way, like an anti-pheromone. This works like a screening function in the mating process. People typically have a strong reaction one way or another towards Sx’s, and vice versa.
Self Pres people instinctively avoid certain foods and environments, and are likewise drawn to those things that nourish and sustain them. Sp’s have a strong reaction against things that threaten to harm their comfort or health.
Social is driven towards gaining protection and empowerment within larger entities.
Soc’s typically react strongly against things which would jeopardize or displace their position or reputation.
The instinct is always trying to work for our survival, whether we know it or not. Personality can only get in the way. Animals, as more or less fully instinctual beings, don’t have this problem. But integrating our personality with instinct requires that each side of ourselves is fully aware of the other side. Otherwise we are automated, automatic, and on autopilot.
