Well, it might be an aversion to the Black|White designation of "Instinct Vs Reason" that the sociology departments are against. Or perhaps they believe that 'all is society", which would make sense from a sociological perspective. That's why we have _so many sciences_; each perspective is good when its in its depths, but each of the sciences has deep flaws. None is immune. If a single science could do it all, it would. But none can, not alone. But they each try in their own way.
