...it can be reduced to one sentence alone:
...pain is a relative comparative measurement...(think upon it)
Vague. Comparative to what? I'd rather you be explicit about your claims rather than hide behind implicit ambiguity.
Premise: Pain has intrinsic moral value
From a foundational basis, ethical issues often center on what is the grounding for normative ethics? Is ethics objective, or is it only subjective in nature?
We have good reason to believe that an external world exists, objectively, and this is a justified true belief
...by the same method the deconstruction of the value of objectivity would necessarily imply a deconstruction of the value and meaning of subjectivity itself...
Those who don't suffer the pain of others, and have no compassion or empathy will assign no intrinsic value to pain. And, of course, they will be exercising subjective judgment.
Pleasure and displeasure are a relative measurement where the value, either positive or negative, attributed to any state of affairs is highly dependent on the referents average fluctuation in the extremes from where expectations are build...
The overwhelming majority of people believe there is a right or wrong in terms of conduct e.g. violently raping a woman is wrong. Subjectivists can't account for this experience, and hence it fails at explaining what intrinsic values explain better.
All belief is subjective? You are going to have a hard time arguing with anyone (including myself) that empiricism in general does not provide good evidence of objective facts. Not everything is in the mind as you claim with "belief is subjective". Common sense people. Common sense.
I should have recalled from previous experiences that you just state a case, without substantiation, and attempt to proceed from your undemonstrated premises
...lets put it plain simple then:
Is your perception of hot and cold water not dependent on the average temperature on which you live ?
Try to place your hand in the freezer for awhile and take it out for a room temperature of say just 5 degrees Celsius..it will feel hot...
The weight of apparent facts doesn’t turn a belief into an objective truth it only strengthens non-objective belief.
I’m not saying that equals everything being subjective.
the way I see it "goodness" is the fine tuning of a system and "badness" it is the disarrangement of an average
