Simply because such a thorough blending of ethics and economics as a positive ethical system had never been done before!
How closely wed is the science of ethics and the science of economics?
They are like the waves of the same sea. Sometimes they roll or unroll together, sometimes they crash together, but always they are filled with the same ocean water.
And then
After submerging ourselves in the depths of this ocean we discovered lost treasures and we brought them to the surface and revived them. Lost was the tool of logic and lost were the gems of the early contributors to the ethics of the divine economy.
Readying ourselves to embark on this journey of revival required a key step of preparation. The first step was to use axioms as guiding principles in the formulation of a positive ethical theory. Such a thorough blending of ethics and economics as a positive ethical system had never been done before.
The journey is very exciting and fulfilling. Hop on board the ship - the Model of the Ethics of the Divine Economy © - and traverse the vast ocean of the union of ethics and economics!
