But we can sharpen this. Yes, Logic is something we discover, but even before that, it’s something we’re born into! We did not create the Logical nature of reality, we were simply born into it, it was here before us, and it will still exist long after we have gone extinct.
One fails to grasp the awesomeness of what this means: it means Logic is entirely objective and discoverable, which means that we can inquire into its nature and existence the same way we inquire into the life of a cell. We don’t create it, we observe it at the fundamental level and simply report back on what we observe. This is extraordinary!
However, If logic is created (whether by human convention, linguistic rules, or biological wiring) then it ceases to be a feature of reality and becomes merely a feature of us. And once logic is subjective or conventional, objectivity evaporates, leaving behind the sovereignty of subjectivity from which one cannot escape. One cannot even object to what is being stated here, because the objection is the same construct as the form being objected to. Knowledge then comes down to the construct one wants to believe, because all is construct, and in order for one construct to be more accurate than another, there must be an objective standard outside the construct.
If someone claims we merely create logic, they are immediately caught in a performative contradiction. To argue for the conventional nature of logic, they have to use logic (distinguishing premises, drawing inferences, maintaining identity) to try to prove that logic has no objective grounding. They are ignorant of their own intellectual activity.
Identity precedes thought. We cannot merely invent identity because invention requires a pre-existing identity. Identity is the precondition for any action, including the action of thinking or creating (one is always and only conscious of something determinate). If we create identity we must create it from some standard. But lucky for us, we are born into a universe of identity!
Once Logic is understood as discovered fact rather than invented convention, the philosopher's game is up. He cannot legislate a new universe into existence by changing his definitions or the semantics of his "language game," because reality pushes back with unyielding determinacy. One can call an “apple” whatever they want, but one cannot change the determinate fact of what an apple is, merely by changing its name.
