The frame of the system is still part of the system.Belinda wrote: ↑Sat Jan 23, 2021 7:07 pm Synthetic a priori depends on naturalism as the frame and system of belief. Naturalism is form of pantheism. The biosphere is an ecological system. Within that system humans retain inherent brain-mind patterns. Chomsky has described generative grammar, for instance, as deep structure of human language.It's probable in a habitat that is measurable by values of space and time that humans, by process of natural selection, are inherently able to synthesise values of space and time.
And I further draw your attention to the fact that you've framed your beliefs in the language of "systems"; and you've framed those beliefs in Chomsky's universal grammar.
The synthetic a priory is still synthesised and in so far as synthesis goes - I think "synthesis" means exactly the same thing as "first principles thinking".
It still begs the question: When we are synthesising ideas (such as the idea of "systems", "space" and "time") what are we synthesising those ideas from?
Experience! Obviously. "space" and "time" are empirical, not conceptual. Space is memory. We don't really know what time is.
