RT Article T1 Brain Roots of the Will-to-Power JF Zygon VO 18 IS 4 SP 359 OP 374 A1 MacLean, Paul D. LA English PB Wiley-Blackwell YR 1983 UL https://ixtheo.de/Record/1827946431 AB Abstract. The human brain has evolved to its great size while retaining the anatomical and chemical features of three basic formations that reflect an ancestral relationship to reptiles, early mammals, and late mammals. Such considerations must be taken into account in the origin and expression of individual and collective violence, which operationally depend on power and the orchestrated use of power. Aristotle and Friedrich Nietzsche have respectively provided paradigms of a “great-souled man” and a “superman”— both basically ruthless. In neurobehavioral investigations of the triune brain, one finds the basis for the hierarchical development of ruthless power, merciful power, and transcendental power.
