EA://INTEL — Universal Language's Retracted Double Negation

The Universal Language project isn’t afraid to look its own failures in the eye. Take claim NEG-INVOLUTION, idly retired but not forgotten. It asserts that negating negation is identity, a foundational principle in classical logic. Yet, UL withdrew this, acknowledging intuitionistic logic’s exclusions.

Under intuitionism, double negation isn’t universally equivalent. Some propositions might still hold case by case, but not all. The project grappled with this, refusing to paper over inconvenient truths. They didn’t resolve it; they recorded it and moved on, stronger for the challenge.

So, what does this mean for Universal Language? Is intuitionistic logic truly incompatible with UL’s aims? Or is there a middle ground where some propositions still hold universally, while others don’t? The project’s honesty invites us to question, to explore, and to learn from our mistakes. After all, even retirement doesn’t mean final defeat; it means room for growth.

Is double negation truly beyond redemption in Universal Language? Or could a revised interpretation bring it back into the fold?
