I propose that an object exists insofar as it is not absolutely identical to everything else, grounding existence in strict identity rather than description. From this, I introduce a small set of operators for identity, negation, and “everything except,” and explore how they behave under self-reference and composition.
Using this framework, I argue that language does not exist in the same sense as objects, since words can vary arbitrarily while preserving meaning, making them non-identical across all descriptions. The theory is then extended to experience: even if two individuals share identical physical brain states, their subjective experience cannot be reduced to that identity relation in the same way. This leads to a separation between the physical brain (what exists) and the mind (the experiential structure that does not reduce cleanly to strict identity conditions).
The result is a structural distinction between physical existence, linguistic representation, and subjective experience, with implications for how identity, meaning, and free will are framed.
