Whether or not the shadows on the cave's wall are a simulation is irrelevant, because the reflection is still an accurate, albeit limited, reflection of what is outside of the cave. In order to function within our realm (the cave), which includes the perception of a possible simulation, we must limit ourselves to understanding it within this realm. Otherwise we get lost in a parallax-perception. Considering and understanding events and laws of nature, it is not pertinent to know whether or not what we perceive is a simulation or real. For even if it is a simulation, to function and manage our lives, we must treat what we see on the cave's wall as an accurate depiction of reality. Because in principle we cannot determine whether or not life is a simulation, because even our pondering of the question whether or not it is a simulation must also be regarded as a possible simulation-a mimicry of thought (thought is reflection, it's what distinguishes us from animals, it's intelligence). A dog does not recognize itself in a mirror. Therefore, we must accept that the question of simulation or not is outside of our realm. Otherwise it becomes an incapacitating conundrum. Our perception will always be relative, anchored. This is why we should not transgress into divinity.
