Relative to a cow, humans are born with a greater range of base-to-high behavior potential, genetically imprinted/encoded (nature vs. nurture dialectic) from one generation to the next. One can easily apply "warrior" behaviors to base, visceral actions, while "priestly" can be mapped to higher evolved states (Maslow maps aesthetics in this higher range, so the myriad of religions that propagate around the world, have their counterpart in essential needs, such as visceral, physiological values, in the lower section of the hierarchy. Compare to Kundalini Yoga's Chakras, and Spiral Dynamics).
Nietzsche is simplifying a myriad of potential behavior matrices that reduces multidimensional probabilities, to linear A-or-B (your "warrior" to "priest" range). When you dumb down, and
accurately map the six degrees of separation between the poles, you can make more money, and translate more sustainable value as an author.
The IMF can do the same, while taking away the higher ranges of understanding, and thereby keep you dumbed down to their monetary tracts that skew value exchange, heavily in their favor. Hint: this unbalancing behavior is exactly the kind of unethical entrenchment that needs to be unseated, therefore, educating the ignorant to higher understanding is paramount to avoiding massive collapses of civilizations.
