You explain subjectivity by it being subjective, that is circular reasoning. You have to put the word subjectivity on one side, then an "=" sign, and then not put the word subjective on the other side of =.
And here you say the person speaking knows as fact, while just a few posts previous you say that when it becomes publicly known, then it becomes a fact. Big mess.
Leibowde:
1 "the person speaking knows whether they were honest or not."
2 "once an opinion is known to others, it becomes objective"
1 implies fact, 2 implies fact.
So you have everything as fact, and you equate opinion with fact, it doesn't add up. It's not a working conceptual scheme.
We all know that the correct answer is that the agency of a decision is the subjective issue, which means one can only reach the conclusion about what the agency of a decision by choosing the answer. That works perfectly, it has no contradictions, consistent with common discourse, traditional religion, just wonderful.
