Dear Tung Ten Yong,
Congrats. A really short and pregnant essay.
Your essay reminds me what Freud called the 3 wounds humanity suffered: earth not at the center, men not at the center of creation and ego not master in its own house. I would say, that this supports your thesis on the Copernican Principle of theories. Shall we call it a forth wound?
Anyhow I think you draw interesting conclusions from this principle. I specifically like, that you do not deny the success of the physical theories. In that sense the success seems really miraculous. But that makes it an interesting working thesis for future physical research.
In my essay I use a milder form of Platonism, saying that the language empirical knowledge must be platonic (ie. mathematical).
Best,
Luca
