That isn't a meaning, that's just long-hand.
Your syntax is wrong, hence meaningless.
If we fix the syntax, it becomes a tautology - always true yet meaningless.
p IFF q is equivalent to IF p->q AND IF q->p, THEN p <->q
so, adjusting for syntax, you've written
IF (a=b) AND IF (b=a) THEN (b=a)
mmm...
Amusingly, also TRUE when both propositions are FALSE.
also,
QUANTA = MEANINGLESS
QUALIA = MEANINGFUL
So you have quantised qualia as having-meaning, and quanta as not-having-meaning, in an attempt to discredit quanta. The paradox is amusing.
everything that sways human emotions is somehow directly or indirectly anchored in private experiential QUALIA
pure QUANTA, like for example, scientific data, before it is "interpreted" and or "concluded", the data itself is not MEANINGFUL (in a human emotional sense)
for example,
if you hear someone say "i'm searching for meaning in my life" and or "everything seems so meaningless"
you can bet
they're NOT looking for a dictionary
In logic and related fields such as mathematics and philosophy, if and only if (shortened as iff[1]) is a biconditional logical connective between statements, where either both statements are true or both are false.
The connective is biconditional (a statement of material equivalence),[2] and can be likened to the standard material conditional ("only if", equal to "if ... then") combined with its reverse ("if"); hence the name. The result is that the truth of either one of the connected statements requires the truth of the other (i.e. either both statements are true, or both are false), though it is controversial whether the connective thus defined is properly rendered by the English "if and only if"—with its pre-existing meaning. For example, P if and only if Q means that the only case in which P is true is if Q is also true, whereas in the case of P if Q, there could be other scenarios where P is true and Q is false.
well copy-pasted, now apply it to your initial statement.
(GOD = EXIST) IFF (EXIST = GOD)
the syntax is valid
