A chair, being neither true nor false and present as a fact or the concept that references one, is only ever the sum over all that it is not and in this sense represents an ontological absence to the presence that inversely defines it. The artefact as teleological narrative or cognitively reflexive endpoint is in this way, and as much as it can ever be said (or confirmed by observation or experience) to exist, foundationally dependent upon that which it is not for whatever reality that might ever be asserted regarding it. All definitions being in the infinite or Global case as tautologies and circularly self-validating instances of reference (or information encoding), the chair is as much, if not more, what it is not as what it is.
Ergo – chairs both do and do not exist. Anything beyond the most remedial of simplifications invokes caricatured abstractions upon which both we and all of our assumptions might still and quite comfortably sit. Any one entity or system, inversely defined and thus foundationally interdependent with what it is not. Here we observe two systems (as binary gradient of difference) that contain each other but find themselves mischievously bootstrapped into and as a single unified system that contains itself.
