Aha, I have (perhaps) a glimmer of insight! I have indeed been

independently wondering how it might be that coherent dream sequences

seem to swamp the apparently-to-be-expected swarms of

inconsequentiality, white rabbits etc in experience and was

speculating that generative, fractal logics might be at the root of

this, contrasted against the background 'noise' of random strings. I

also speculated (note: upcoming gibberish warning!) that the compact

computational specifications of such logics might comprise the sort of

subtle 'intension' that could constitute 'intention' at the roots of

RITSIAR. IOW, if numbers and operators together are taken to subsume

and collapse the intuitions of being, knowing, perceiving, acting and

intending, then perhaps the numbers refer to the being component and

the operators to everything else. Consequently, compact complexes of

operators constituting generative logics of the self-dovetailing kind

you describe might plausibly stand for the 'subtly intentional' and

coherent activity that characterises RITSIAR, as opposed to the white

noise of random concatenation.

Can you find any communicable content here?
