Civilization, as we know it, is largely the creation of psychopaths. All civilizations, our own included, have been based on slavery and “warfare.” Incidentally, the latter term is a euphemism for mass murder.
The prevailing recipe for civilization is simple:
1) Use lies and brainwashing to create an army of controlled, systematic mass murderers;
2) Use that army to enslave large numbers of people (i.e. seize control of their labour power and its fruits);
3) Use that slave labour power to improve the brainwashing process (by using the economic surplus to employ scribes, priests, and PR men). Then go back to step one and repeat the process.
Psychopaths have played a disproportionate role in the development of civilization, because they are hard-wired to lie, kill, injure, and generally inflict great suffering on other humans without feeling any remorse. The inventor of civilization — the first tribal chieftain who successfully brainwashed an army of controlled mass murderers—was almost certainly a genetic psychopath. Since that momentous discovery, psychopaths have enjoyed a significant advantage over non-psychopaths in the struggle for power in civilizational hierarchies — especially military hierarchies.
