His argument overly reduces important ethical issues by focusing on unrealistic scenarios that do not capture the structure of morality in the real world
Unrealistic scenarios? JFL, if a tree falls down in a forest, but no one witnessed it happen, is that unrealistic?

If a landslide or avalanche occurs in some remote location with mountainous terrain, and no one witnessed it happen, is that also unrealistic? Ultimately I cannot be sure, but I'm willing to bet there have been many fallen trees, landslides and avalanches in the world that were witnessed by no organic being
Human consciousness does not exist in isolation, but rather in a body that interacts with the world. The body, being a vehicle of consciousness, translates these intentions into concrete actions, where good and evil manifest themselves in a tangible way through your choices. Conscience is the means by which we perceive and act in accordance with moral concepts, the idea of good and evil transcends only your individual perspective. It manifests itself in physical form through the choices that man makes with his body. Morality is not something merely abstract.
I will correct what I believe to be error in my previous response: I agree that morality can transcend individual perception. My original statement was, "
the concept of morality is contingent on existence of knowledge; it is a concept that is essentially relative to the existence of knowledge" . This was a faulty statement
My point is morality is at least related to "human consciousness", and the practicality of moral behavior derives from perception. The concept of morality is not practical without observers. Why? The purpose of morality is to attribute a certain "value" to human behavior - A "value" that is believed to transcend the physical realm.
This doesn't mean "morality" is abstract in the sense of its appliability to external world. Instead, it means "morality" is abstract in sense of its INTERPRETABILITY. Morality can be made sense of within the realm of "human consciousness", but not outside of it
Moreover there is a fundamental, underlying notion of "punishment and reward" in the concept of morality. That is, for every "good" there is a "reward", for every "bad" there is a punishment. The purpose that morality serves would be redundant without the underlying notion of "punishment and reward"
Secondly, the suggestion that "good and evil can be manifested in a tangible way", is misleading. As I previously said, morality is supported by the underlying notion of "reward and punishment", and the "tangibleness" of "moral deed" is based on some idea of what is of "morallity"
But this "tangibleness" of morality is not a scientific or impartial tangibleness - It is a subjective tangibleness. Morals are relative to cultures and personal beliefs. An action or behavior that may be recognized as "evil deed" for one person might not necessarily be recognized as "evil deed" for another person
Let's say some incel picks up a gun and shoots Becky. Then can it be said by believers of morality that the incel committed an "evil action" because he injured Becky, or can it be said that incel simply decided to injure Becky on impulse or survival instinct? Also is it necessarily "evil" just because the consensus says it's evil. The fact that many people share the same belief doesn't necessarily make that belief "true" in the objective sense
But let's say the incel's decision to shoot Becky was calculated and was not done for reason of self-defence or survival. If someone would then say it was evil deed for incel to shoot Becky, then why? Is it because it would be believed that it amounts to a sort of "moral (evil) deed" by shooting another human like Becky?
Ok, then why would someone believe that shooting Becky is an act of evil?
Is it because of some underlying system of laws and codes that moralizes the concept of causing injury to another human? If it is, then it's clear the so-called "structure of morality" actually derives from LAW. This is another subject that I've covered in an older thread
Is it because of human ego, where someone believes there is a sort of "metaphysical significance" / "metaphysical importance" in the human existence, hence it would be "evil" for someone to cause harm to the health of a human? If it is, then it's clear the so-called "structure" of morality actually derives from EGO
It's like this - Morality stems from LAW OR EGO. Either humans think they're "special" and that their existence serves a "greater purpose", which explains why they attribute these strange concepts called "righteousness" and "evilness" to their own actions and behavior
Otherwise humans believe in a system of law that was preordained by a higher power (presumably a deity) and bestowed upon mankind (Law of Moses, Sharia etc), and this system of law calls upon certain actions or behaviours to be "moralized" with the promise of divine reward (for anyone doing good deed) or promise of divine punishment (for anyone doing bad deed)
Morality endorses behavior on the basis of mysterious ideas about “right and wrong”, “properness and improperness”, e.g., “You should do X because it is righteous or proper to do X. You shouldn’t do Y because it is improper or evil to do Y” Laws are declarations or commandments of the authority...
