The Humanities are awash with conflicting, baseless explanations of Human Nature. Sociology, Psychology, Rational Choice theory, Religion, Marxism, Feminisim–all fail in their EXPLANATORY power when tested for consistency when they butt up against the observable actions of real human beings on the Planet.
That humans are able to build entire intellectual edifices out of words with NO referent to underlying reality is a difficult concept to get across to most people. They see an imposing body of work like “Freudian Analysis” or “Keynesianism”, replete with “Experts” and PHDs and grant proposals and they simply ASSUME the field of study has real world merit, how could all those books written in Universities NOT be true?
You really have to ask yourself–given that they fail time and again in their predictive power regarding how humans behave and that they are composed of a plenitude of competing fundamental first premises, how could ANY of them make any truth claims at all? Feminism told us Men and Women were NO different irrespective of our visible and extreme sexual dimorphism, Marxism told us we belonged to immutable classes, Sociology claims our nature is shaped by environmental forces that can be easily manipulated and yet their grand schemes like Head Start fail to produce enduring results time and again, and in Economics, Rational Choice Theory is forced to generate a silly list of anomalies and paradoxes to handle the fact that human behavior REPEATEDLY deviates from what they have determined “should” be rational”.
In his article Take The Evolution Challenge, David Sloan Wilson eloquently proposes that Evolution Theory be used as a Universal Solvent for all of these competing theories, burning away the accretions of years of constructivist and ideological fat and uncovering the truth.
