Thanks for this clarification. It seems unusual to define "external facts"<BR>
to include observation of mental imagery. However, if that is the case, then<BR>

knowledge of the "internal world" by direct observation of our thoughts (or<BR>
at least, direct observation of our self-verbalization of our thoughts).<BR>
