The loss of the dimension of action from philosophy due to the invasion of platonism and religion is the reason for two millennia of limited progress. I suspect at first this was a linguistic limitation of early languages, combined with the history of animism, plus … one thing that is obvious to me… that operational language is expensive. Not just in words, but in the number of subset searches you must perform to convey an idea. So truth places a much higher burden on us until we develop a symbolic language for it that shortens the burden on us.
Just in my lifetime I perceive the difference in the metaphysical content of our language only half of which (science and probability) is beneficial, while the other half (high time preference, individualistic immoralism) is tragic.
As you go back, every generation it recedes into much clearer dialog using very clear references on one hand (enlightenment thought) then degrades into mystical thought. But if I must judge, I would say that we speak more superstitiously now than we did under the church.
Anyway, I have tried to restore all dimensions to philosophical argument and unite philosophy, morality, law, and science, as well as psychology and social science, into a single universal language.
Unfortunately that language is tedious. Just as I am sure science was tedious, and just as I am sure that removing animism, adding probability and evolutionary processes…. all were tedious.
But each transformation made man better than he was before.
