Apollo & Dionysus#
Wisdom (Streets, Earth-Bequest)
Vigilance (Owl, Trunk-Resources)
Noise-Capital (Molecule, Faustian) vs. Sigma-Talent (Epitope, Islam)
Distributed: Self (Helmet, Takaful), Negotiable (Shield, Sharakah), Nonself (Spear, Darabah)
Illusion (Lyre, Ukhuwah)
— Dionysus is filtered through Athena!

Fig. 10 Immitation. This is what distinguishes humans (really? self-similar is all fractal). We reproduce language, culture, music, behaviors, weapons of extraordinarily complex nature. A ritualization of these processes stablizes its elements and creates stability and uniformity, as well as opportunities for conflict and negotiation. These codes illustrate the key points made in Sapolsky’s discussion: the limits of reductionism, the role of chaos in biological systems, and the fundamental nature of self-similarity in complex structures.#
