Philosophical Realism as adopted by PH and realists is defined below;
Radical Embodied Cognition is a basically Philosophical Realism, i.e. there is real independent objective reality out there, where "the percepts we have must be direct reflections of information that is in the real world."
"
If space-time doesn't exist then that cup is not a 3D object fixed in a particular location in space, despite the fact that my perception tells me it is.
And if this is true [
Philosophical Realism] is a dead theory."
PH is relying on his philosophical realism [dead theory] to deny morality is objective.
On the other hand, my view is anti-philosophical_realism [Kantian], i.e. there are human based moral FSK facts which are objective, thus morality is objective.
I don't understand the objection.
Space-time is an interpretation of a part of reality. Do you interpret that space-time is matter and energy?
Your cup is a material object with which you interact.
In space-time, the cup is the continuous flow of the elements that form it, through the entire continuum.
---
Perception is not information transmitted by light. The cup is not light with a certain structure. The cup is a part of reality, from which you deduce its existence by interacting with elements that have interacted with it.
There is, the cup (part of external reality) and the concept cup (a neurological structure in your brain).
The fidelity between the two cups does not only depend on your interaction with light that has interacted with it. It also results from your electromagnetic interaction (touch), from the result of its interaction with other objects in the cases that you use it as a mediator of some action, from the coherence in the cases in which you refer to it with other humans, etc.
Each element of the cup does not have a definitive location in space. The cup has a probabilistic location in space. The probability of its location is almost accurate. For practical purposes, it is placeable.
That space and time are emergent phenomena is only speculation useful for exploration.
I have the impression that mathematical models are being explored that allow scientists to analyze whether this is a non-contradictory possibility.
That is not the same as saying that Quantum physics has revealed that space and time are illusory entities with no correspondence to reality. only illusions
Without the concept "interaction" not only would classical physics not exist, nor would quantum physics exist.
Without space-time there is no interaction. The concept falls.
On the other hand, when you look at what is recorded by a video camera, the reality that it represents has lost a dimension. But you see events that have a complete correspondence with what happened in reality. Your understanding of the situation allows you to make the right decisions based on what the video showed.
If I were to show you a crude stick figure animation showing a certain circumstance. you would be completely effective in interpreting what was shown.
What's more, I could convey to you what happens in a certain circumstance without you having to have what is narrated spatially arranged. By narrating it orally, for example.
These factors do not affect the matching fidelity between the two cups.
I don't see how this is related to a supposed objective morality.
Note sure what is your point?
The OP point is this;
1. For example, our percept[ion] of a cup is the direct result of light interacting with a unitary object [the-perceived-cup] that has a definite location in space.
2. Recent work in physics has suggested that something like quantum weirdness applies also to the very large, that
space-time doesn't exist at all.
If space-time doesn't exist then that cup is not a 3D object fixed in a particular location in space, despite the fact that my perception tells me it is.
And if this is true REC is a dead theory.
3. Therefore there is no independent objective cup within a definite location in space.
4. Peter Holme's [PH] sense of what is objective reality is the same as 3, thus ultimately false.
5. PH denial of moral objectivity is based 4 above, thus false.
6. My claim of moral objectivity is not based on PH's basis, but rather based on human-based FSK basis of objectivity. I have argued this human-based moral FSK is tenable, thus moral objectivity in this sense is tenable.

You mention this:
". Philosophical Realism is .. about a certain kind of thing .. is the thesis that this kind of thing has mind-
independent existence, i.e. that it is not just a mere appearance in the eye of the beholder."
But
Quantum theory does not contradict the existence of something independent of mind.
Quantum theory does not contradict that the human mind results from a functioning brain.
Quantum theory does not contradict that the elements that behave quantum, exist independently of the functioning of the human brain.
The fact that there is a limit to the knowledge of the position of an element of reality does not mean that this makes it dependent on the human mind.
That space-time is speculated to be emergent properties of other underlying levels does not mean that the quantum elements are dependent on mind or that they do not have a causal relationship between them and that this relationship is described in temporal-spatial terms.
---
On the other hand, it seems to be affirmed that:
- If the mind does not build anything
- The perception of a cup must be the result of the interaction between light and a cup in space.
and
- If in the universe there are no unitary objects (cups).
- Perceiving a cup must be a creation of the mind.
They are incompatible with each other.
Also your quotes:
"If space-time doesn't exist then that cup is not a 3D object fixed in a particular location in space, despite the
fact that my perception tells me it is.
And if this is true [Philosophical Realism] is a dead theory."
No. That space-time is supposed to be an emergent phenomenon does not mean that it does not exist. In the same way that if the polarity of a molecule is an emergent property, this does not mean that the polarity is an illusion or that polar molecules do not exist.
Once again, the fact that space-time is an emergent phenomenon does not mean that an element of reality does not exist or does not have a certain particular relationship with the rest of the elements of reality.
Affirming that the elements of reality do not exist leaves you in an absurd position from which you cannot affirm anything.
An element of the universe is a unitary object? Does an elementary particle exist or not? (The one that behaves quantum).
---
The concept of objectivity is just a practical convention to indicate where the factors that affect something are minimized, when they have no relevance in a certain interpretation.
Since "objective" is that which does not depend on human interpretation and that there is no circumstance that humans can distinguish that does not depend on that interpretation, it is absurd to suppose that there is anything objective.
including morality.
