@MattDavis,
Quote:I find it highly implausible that a society would construct such an elaborate model for reality.
Are you conditioned by "Occam's Razor" thinking here ?
Quote:Do you think that prior to an understanding of Newtonian Mechanics the "reality" was magical?
All "God" premises, including Newton's and Einstein's could be called "magical".
What those geniuses did was to extend our powers of prediction and control i.e. they enhanced our range of potential functioning.
Quote:I have a very hard time agreeing that "reality" was in fact different when our perceptions were different
That's the naive realist bedrock position. It is is the non-constructionist view of "fact". It ignores the view that "reality" is an
interaction between observer and observed. The frog who starves surrounded by what we call "dead flies" has
its reality specific to its perceptual apparatus. And only "gods" have no perceptual limits.
Quote:You claim phenomena is all, because all we experience are phenomena.
No, I claim "we" don't
experience phenomena, our
verbal reports of "a phenomenon" involve a
we state plus
things functionally related to that state. We are part of the phenomenon.
Quote:Why then ever try for understanding?
Because attempt at enhanced prediction and control is an evolutionary advantage.
Quote:What is the existentialist argument against willful ignorance and/or nihilism?
Probably too general a question requiring a doctoral dissertation !
The existentialists differ between themselves as to the nature of "existence" and "reality". Sartre, for example, goes towards the nihilist pole (notably in his novel
Nausea which dwells on the (social) madness of being fixated on
non functional detail like dust on bookcases). Heidegger holds the view that "authentic living" involves understanding the nature of "being" in the constructivist sense. Derrida ( a post modernist rather than an existentialist) dwells on the transient and dichotomous nature of
reportage and hence the impossibility of segmenting "reality" into permanent functionally independent categories. (e.g "giving" necessarily involves "taking" on the part of the actor).
