@cicerone imposter,
If you agree that meaning is contextual, you are agreeing with Wittgenstein that
meaning is use. Now apply that to the word "reality" which W might argue has meaning in
normal usages like
"In reality the man was a thief even though he denied it",
but has NO meaning in concocted phrases like
"Reality is what is",
since this has nothing to do with "real life" communication.
W, would call this use of "reality" and even "is"
language on holiday.
As for "explanation" in economics , to some extent this relies on how far you are prepared to take economics towards the idea of universal laws in the hard sciences. Since the answer to that is "not very far", you are left with statistical laws whose probabailistic "logic" is based on anthropomorphic concepts like "the average man" or "the market".
We perhaps need another thread to examine the word "explanation" significantly but in general we can say it involves the phrase "reference to a
satisfactory set of predictive (or retrodictive) principles". The problem word there is of course "satisfactory".
