Amos..I don't DO 'bounded' philosophy, and phenomonology, by definition is not bounded...it is merely an approach to describing "the thing-in-itelf"...whether or not the 'thing' has any objective reality! If the only way you'll allow UNbounded thinking is to require that we 'accept in order to see', I'd suggest that we have a serious difference of opinion about what constitutes 'bounded'.

As to 'self-referential chains', what do you you call a system that assumes concepts in order to describe, define and speculate on their nature? "Now let's all stipulate that 'spirit' and such like nouns are really relevant, and in an important sense, "there"...here's what they must be like!"....ummmmmmm

Little Hawk, our resident monkey certainly does a fine job of narrating the Emperor's parade and describing his wonderful clothes, but there several little kids around here who can't quite see them. Maybe if we squint REAL hard and tap our heels together three times....
