The network of high concepts is the raw material, not the finished product. Exploring their breadth and integration is one task. And expressing one's discoveries in an accessible way is another. Jesus brought the philosophy of religion down to earth. Expanded and exquisitely integrated concepts.
Expanded concepts have tentacles into many fields.
Familiarity with such concepts, the more extensive the better, is another major requirement for those who aspire to join in the construction. Exquisite is a quality of artistry. Plato attained heights of artistic philosophy that have not been reached since. Evolutionary cosmology, philosophy, and theology were not frozen in 1934. To survey the ripening planetary harvest of expanding concepts, ongoing study outside the book is required.
