Logic requires that deductions follow from specific axioms. Empiricism demands than any logical structure explain and be in absolute accordance with all directly observable facts (it’s a little more complicated than that, but I’m making a different point here). But what are the “facts” and “axioms” we should use to reason about social policy and values, especially in regard to the creation and criticism of laws and their enforcement. How do we weigh the “reliability” of an “observable fact”? How do we pick our axioms?
Obviously legality cannot establish truth; I’m talking (in part) about the means by which we create and modify the laws themselves.
Religion seems a poor method. The details of various religions differ too widely for a multicultural nation such as ours to peacefully negotiate our ways of living.
I suppose warfare is at least authoritative. Kill everyone who disagrees with you, and any position will become obviously true to everyone. Again, however, this seems an unsatisfying solution.
Merely insisting on internal consistency is not sufficient. Mathematics has shown that one complete (to Godel limits) axiom set can completely contradict another complete set.
My original position of accepting consensually accepted beliefs as axioms or observable facts and then using them to reason solutions into uncertain or controversial areas has been roundly criticized by people I both admire and abhor. So I’m in doubt about the value of this idea.
Perhaps rationality and logic themselves are poor methods for discussing social policy and values.
Can anyone offer a better solution?
Remember, I’m not talking about which values and policies are correct, I’m interested here in how we make the distinction in general between correct and incorrect values, “good” values and “bad” values.
