[Summary] This text explores the potential evolutionary origins of the Enneagram system, a personality typing system that categorizes individuals into nine distinct personality types. The author, Dr. Saleh Vallander, posits that the Enneagram's underlying principles may be rooted in the brain's emotional systems, as described by neuroscientist Jaak Panksepp. He argues that the Enneagram's three ‘Triads’ (Anger, Grief, Fear) correspond to Panksepp's primary negative emotional systems of RAGE, GRIEF, and FEAR, while the Enneagram's three ‘Instinctual Drives’ (Self-Preservation, Sexual, Social) correspond to Panksepp's positive emotional systems of SEEKING, LUST, CARE, and PLAY. The text then explores how these emotional systems might have evolved in animals, speculating on when and why the Enneagram's nine personality types might have emerged.
