We may need to add a tru tag to the conceptual flag-panel in the various AI Minds, such as in Forth and in Perl. Only the first word in the thought-engram will need a tru tag. We may want to have the following tags in the panel.
tru psi act hlc pos jux pre iob tkb seq num mfn dba rv
Active code will probably assign a numeric "true" value, so that only the most current thoughts will have an assumption of truth and believability. Preterite be-verb assertions like "Kilroy is here" shall have decayed down to a low tru value so that they will not be taken at face value by the thinking Mind. On the other hand, non-be-verb knowledge about the ontology of the world will need to be regarded as true.
As the thinking AI associates from thought to thought, sentence-engrams with a low truth-value should not come into play. Various criteria may cause some engrams to go to a mid-range truth-value and other engrams to a minimal truth-value, so that reliable knowledge may come into play.
The tru-tag will permit rather elaborate ideas to emerge back into consciousness with emphasis on special considerations such as the inclusion of a prepositional phrase in the idea, as in a sentence like, "A man with a boat needs money". The 3D AI will therefore need not only modules for thinking with prepositional phrases, but also modules for conjunctions to be used in sentences like, "I know that time is money" or "I think that boats cost money." The routines for comprehension will need to be modernized or adjusted to allow parts of a long input sentence to be comprehended upon selection of a likely subject.
To some extent, we are aiming for a conscious AI Mind that realizes that it lives inside a computer and that it has only limited interaction with the outside world. It may need the ASCII bell-function as a way of deliberately summoning the attention of a human user.
