In ordinary usage, 'real' is merely an antonym for 'fake'. It's probably best to collapse most distinctions involving the word 'real'. The real question is, "Can you be wrong about a prediction?", and then you can stipulatively label the thing that generates the experimental predictions "reality" if you'd like. The Simple Truth.
Yup. That link contains one of the simplest and most effective antidotes to non-realism I know of:
I need different names for the thingies that determine my predictions and the thingy that determines my experimental results. I call the former thingies ‘belief’, and the latter thingy ‘reality’.”
From Being a Realist (even if you believe in God):
My mother, who doesn't call herself a theist (I think she's agnostic), doesn't even accept realism. She doesn't even agree with this:
That's little more than tautologies here. Yet it elicited an impression of being forced to believe. I know because she told me about the totalitarian dangers from such narrow thinking.
I'm happy to have finally found the root cause of our ongoing disagreement, but now, how can I deal with that? It looks pretty hopeless, but just in case, does someone have a suggestion, or should I just leave it at that? (My ego doesn't like it, but giving up is an option.)
Now I'm relieved to know that in near mode, she's a complete realist. This craziness only shows up in far mode.
