You received a combined doctorate of philosophy and physics, but you turned to economics. On the other hand, you consider psychology to be a complementary science to economics. I am sorry to disappoint you, but I am a materialist to the core and, philosophically, probably the last positivist. I am, therefore, an agnostic. Still, I do tend to think that all the branches of knowledge are manifestations of essentially the same thing .
Reality is monolithic.
It is our shortcomings as finite humans that prevent us from grasping the totality. Therefore, yes, I believe that economics, psychology and philosophy are all facets of one and the same reality. The other two parts of the book are analyses borrowed from the spheres of economics and history. One can hardly advance a thesis, which pertains to both history and economics without relying on historical and economic facts. What I tried to demonstrate in the historical part is the inordinate power of myths in this region mainly the power to generate more myths.
