Is objective morality imaginary? “..... for objective morality to exist in my view:.....”
In your view, apparently, the possibility for objective morality is predicated on the ability of both mental and non-mental machinations, such that both are embedded with a moral stance. Given that for mental existents, or as we know them, moral agents of a rational nature, the primary requirement, the absolutely necessary condition, for the determination of any moral stance is reason, and given that non-mental existents by definition have no such absolutely necessary condition.......how would any rational agent recognize a non-mental agent’s stance as moral? Granting that it is not required that a stance taken by one kind of entity conform to the congruent stance of another kind, it remains that the difference in the ground of each respective stance negates the possibility of equal consideration of their value. A non-mental existent may be morally inclined, but mental existents will have no means to understand it as such, hence will never know of it, which makes “objective morality” of this fashion moot.
Such is not the case if objective is meant to be that which is not subjective. If the qualifier is merely a “moral stance” in general, without regard to what volitions that stance actually exhibits, a rational agent with a determinable will is immediately presupposed, in order that there be a moral stance at all. Hence it is clear that from the perspective of each and every separate and distinct agent observing an action predicated on a determinable will, warrants the claim for objective moral stances, or, which is the same thing, objective morality.
The argument that by objective morality it is meant that any and all moral stances absolutely require precisely equitable volitions for a particular event, is absurd, at least under the common conditions of regular human life. Still, it is conceivable that relatively small groups of rational agents in a common culture may invoke equitable volitions in response to an administrative code affecting them all, but we might just call that ethics, not morality.
Yes? No? Maybe?
