First, you want us to look at 19th century justification through a 21st century cultural lens. Second, you totally ignored how we are to evaluate the 21st century: which has anything but consensus. Third, whatever method you are going to propose in your next post must be capable of producing a moral fact that is good for all time in human past as well as the future--in order to be considered objective.That's not what it means for something to be objective, as I've repeatedly explained to you across threads and time. It's easy to explain why. If someone had measured the water level on the seawall in some town in 1800 - that would produce an objective fact. If they made the same measurement in 1900 and 2000 (and then in 2100) it would not be surprising to find that the water level had changed and at no point would any of the disparate measurements be any less objective or accurate than the previous or next measurement on grounds of having been different from each other.
Relevant facts of a matter can change, if and when they do change, any objective moral system must change to remain -objective-. It would be incoherent to toss out todays measurement, or claim that it were a subjective measurement..just because the water was an inch higher or lower than it was 100 years ago or would be 100 years from now.
Do you understand?
Okay, let's clear up the definition of objective:
Quote:A proposition is generally considered objectively true (to have objective truth) when its truth conditions are met without biases caused by feelings, ideas, opinions, etc., of a sentient subject. https://en.wikipedia.org/wiki/Objectivity_(philosophy)
What "relevant facts of a matter can change" on a moral question like abortion that does not involve "biases caused by feelings, ideas, opinions, etc., of a sentient subject"? Is there metaphysical reasoning you can employ? Is there scientific reasons you can trot out? Please be specific because it really seems the crux of the abortion issue always was, is, and always will change based on an opinion of relative value of the mother's reasons against that of the unborn baby.
