I’ve experienced an epiphany of sorts. I am a moral non-cognitivist. Most would consider me to be a moral subjectivist or relativist. There’s a distinction, but to the public at large, it doesn’t much matter. In fact, we are all at the mercy of the cognitive deficits of the societies we find ourselves in, each culture having its own deficits. I find it difficult not to come across as an elitist in the space, especially as uninformed and otherwise misinformed most are in this space.
It’s one thing to have an academic disagreement. It’s quite another to have an academic argument with kindergartners—armchair spectators in highchairs and booster seats. Anyway, enough of the ad hominem. I’ve had my say and my fill.
All morality is constructed. Full stop. The basis is the survival and propagation of the society, though societies are dynamic organisms with different goals and purposes, so these foundations may differ. In some cases, they are strikingly similar.
All morality is constructed. Full stop.
It makes sense that most have an element of ‘thou shalt not kill’ with an exception for ‘unless they undermine the culture’. This also allows for ‘killing in order to defend the culture’, even if the people defended aren’t all in sync as to what they are defending.
So where does relative pitch come into play? you ask yourself.
Sound, hence musical tones, manifests as frequency (and amplitude, which I’ll ignore). It is common to establish an A pitch as 440 Hz (440 cycles per second), also known as A440 or A4. Whilst there have been and are other standard pitches, A440 is considered to be the standard concert tone for Western music and has been adopted in other regions. I won’t bore the listener with nuance around A332 and A442 centres, as it’s unimportant to the focus.
Whatever the centre, some people have perfect pitch and others have absolute pitch. Some people are tone deaf, and I suppose that to be a perfect metaphor for some people in society, but that’s also an analogy for another day.
A person with perfect pitch not only has the vocabulary of music stored in memory, but they can retrieve it on a whim. I’ve encountered several people with perfect pitch, and it seems inevitable to engage in parlour games. With piano at hand, it’s easy to play unseen chords and have the absolutist bark back F#min6/9 or some such. Even more amusing is the result of tossing a shoe at an object to hear what note the clang might correlate with. That stool was a B-flat.
I thought I was wrong once before, but I was mistaken.
Whilst a person with absolute pitch can pick notes out of the air, a person with relative pitch doesn’t have an anchor. In either case, a listener can tell you that the interval between an A4 and an E4 is a perfect fifth, the person with relative pitch can’t name the notes without guidance. Of course, once the listener is clued in that the first note is an A4, relative maths does the rest of the heavy lifting, so they, then be able to tell you that the note a perfect fifth above is an E4.

It’s important to know the vocabulary are rules as well. For example, many of us can recognise the interval at the start of Beethoven’s Fifth Symphony—da-da-da-DA…! We can hear it in our heads as we consider it. But we don’t know that the first three shorter notes are G and that the longer final note is E♭.
Thanks for the music lesson, but you’re asking, ‘How does this connect to morality?’
Unlike music, morality has nothing analogous to absolute pitch. Moreover, different cultures have different reference pitches. And some cultures with the same reference pitch are playing in different keys. The challenge is that whether or not the dominant culture has absolute pitch, it still presumes it is the tonal centre. And if it’s tuned to A432, you’d better be too; otherwise, there will be dissonance.
Referencing the Venn diagram, one can see the primary culture, C0 occupying the most space and acting as a centre of gravity. There are subcultures, some with more and less in common with the primary culture.

C1 has much in common with C0, but the majority of ideals are not shared. It remains to be seen whether these differences are material. For example, the difference may be preferences about food or clothing, perhaps which holy days to recognise to whether to recognise any at all. In practice, these cultures could very well coexist with little conflict.
Similarly, C2, may be able to coexist with either of both with little friction. Of course, the difference may be significant. Perhaps, one difference is their view on abortion or female circumcision. Clearly, these are dancing to a different tune.
Perhaps, C3 is some indigenous society. C3 has nothing in common with C0 or C2, only sharing some ideals with C1. I don’t feel this would be possible in reality because I can’t imagine a culture having opposing perspectives, even if only on the position of not killing other ‘innocent’ humans without cause. The range of causes may differ, but the core value would still be shared.
My point is that the primary culture will assume that its position is absolute, even if just from having enough mass to force the matter. And this is the difference. It doesn’t matter whether their morality is absolute. If you don’t comply—especially in matters they consider to be morally important—, you will be punished. In the case of C3, C1 may tolerate whatever the two are in common, but if C3 attempts to interact with C0, this tolerance is unlikely.
Perhaps, C3 clubs baby seals, eats dogs, or some other such hot-button activity. In their native territory, this may go unnoticed, but if they relocate to the territory of the primary culture, this will not likely go unchallenged.
If you are someone like me who feels that all morality is fabricated out of thin air—even the morality I happen to agree with in principle and in practice—, there is still friction just to suggest that their morality is a constructed social fiction. It seems that many if not most people want to believe in the notion of ‘inalienable rights’ and God-given morality or some sense of cosmic moral order. People like Jordan Peterson believe this as do his followers. This creates contention with others, like myself, who fundamentally disagree and who ask for just a modicum of evidence of their claim. You will comply or you will be chided and marginalised.
Of course, I could be wrong. I thought I was wrong once before, but I was mistaken.
