Is Moral Nihilism a Morality?

[vulcanlogician]

Next, how shall we account for / describe the different perspectives of reality?
Should there be a distinction between ‘reality’ and say, ‘virtual reality’?  Or physical vs. logical etc. ?

Logical discourse and empirical investigation are good ways of accounting for different perspectives. But all perspectives that seem viable must be constantly challenged. They must earn their place as "plausible truths."

Should there be a distinction between ‘reality’ and say, ‘virtual reality’?  Or physical vs. logical etc. ?

Sure, the modifier "virtual" does a good enough job, it seems. Or maybe we can say "virtual reality" is but a part of (if I may coin a new phrase) "reality reality."

How to distinguish the physical and logical? This is Plato's project if I correctly understand what you mean. What do you mean by "physical vs. logical"?
