Truth has nothing to do with humanity unless you mean the specific way humans construct belief systems.
Anyway I already told you the answer. The AI will need a series of trainable belief systems to verify whether statements are internally consistent. The strange part about this is that the AI would need to have a way to obtain validation and each prompt would have to derive a new belief system which you must use in the next prompt.
In other words, the model must be able to learn continuously. That is something that these single shot AI models are not capable of.
