I am not the one saying that synergies are constructs fabricated in our minds. You might as well say there world is flat.
Interesting debate. May a 3rd Engineer throw in a thought or two?
Copernicus was a heretic. According to the Holy Roman Church he was dead wrong in his theories. Remember, the Church WAS the scientific body of the day. Copernicus, as it turned out, was right...
Ever stand in a window on a sunny winter day and marvel at the warmth pouring through the pane? Of course, today, we know that it is due to mid- and long-wave IR emission from the sun that is transmitted through the glass, converted to heat and sensed by our amazing nervous system as pleasantly warm. We can put numbers on the wavelength ranges, the incident power per unit area can be quantified. Not so long ago, it was a mystery. It just felt good. It stirred something in someone, though...
I find many qualities in musical enjoyment that I can't quantify. Perhaps, someday, 5, 10 or 100 years from now we may be able to put numbers and new, unnamed units, to describe "synergy", "sound stage" or hell, even "euphonic". And don't even get me started on "burn in"!!
Respectfully, look back at the history of the units you use every day: Hertz, Amps, Volts, Coulombs, Watts, Joules, Calories, Candela, ... The list is very, very long... Might there be room for a few we haven't thought of yet? Or, are we so arrogant to think and posit that "The Science I Know Today is the Culmination of ALL Science!" or "Whatever there is to be learned has been learned already"?
