drmoose: I could very well be wrong, Mark, but, what I think Lee was going for was to substitute "level of understanding" for "beliefs".
Doesn't make much diff Doc..whether it be,
" If the most important beliefs...."
or
" If the most important level of understanding..."
Are not the main point.......it is this,
.......................................................
".^^^.....a person holds to be true can't be supported by sound argument and evidence, the person should probably re-examine those beliefs"
?
