If there are five stones on a table, there is no judgement needed to count them. If you have a measuring stick, there is no need for judgement to determine their width, height and depth.
But some things in life, like how you feel about something or someone, or how beautiful a sunrise or sunset is, or even how much salt or pepper to put on your food, are sentimental, in the sense that they rely upon mutable, unfixed, unmeasurable judgements. In judgement, you can be relatively right or wrong, as measured by the progress of your feelings. If you feel something makes you happy, and that feeling continues to grow, then you were likely “right”.
No scientific process can bring this process into the measurable. Complexes of feelings are composed of hormones, neurotransmitters, nervous excitation or relaxation and the like. All of these things can be measured. But the feeling is the essence of being human, and even TRYING to bring this into the measurable is in my view fundamentally misanthropic. It is short sighted, reductive (by definition), and unnecessary.
Why can we not admit, in principle, that some things are best “known” through poetry and song? It is a species of savage narcissism and profound discomfort with the facts of life that refuses this very REASONable request.
Yet, we see it every day. Wherever the sun is shining on the Earth, it countenances stupidity.
