Subjectively, I don't feel like I can distinguish shades of joy or anger with infinite precision. I can't properly express my feelings the same way I can't properly express exactly where between blue and green a certain turquoise I'm looking at is. But I know a scientific instrument can give a number for the later and I don't feel I have any basis for ruling out the idea that some future scientific instrument can quantify the former.
