@JLNobody,
That particular "Frank" (which is evoked/triggered by threads on "belief") is blind to the significance of the fundamentally temporary nature of "self" and "its world". In fact that "Frank"
defines itself by such blindness by usage of phrases like "what he knows". All he, or anybody else might call "certain" amounts to a confidence in
a belief in "what works" for various personal and joint human enterprises, irrespective of the views of absolutists who assume we can say it is anything more than that. Even the phrase "set in stone" implies an ignorance (i.e an ignoring) of the ephemeral geological events in which what we call "stone"was formed ...ephemeral that is. relative to cosmological time scales as measured for some current human purposes, and which potentially relegate states of "human knowledge" to ludicrous levels of insignificance.
As usual we can now expect
that Frank to thrash about with objections aimed at its concepts of "fresco" or "JLN" as though they were permanent consistent "selves". They are equally
evoked by the context of this thread .
