in physics, when describing a phenomenom with numbers it is common to have two models: ideal and real. for example, an "ideal diode" has a beautiful, simple equation. when i was young and idealistic the corresponding "real" equation upset me, as it revealed (and compensated for) all sorts of physical realities small and large. reality, a mess.
i wonder how my earlier self would've responded to theories of consensus reality and intersubjectivity.
