Monad, Microcosmos. Macrocosmos

Leibniz' model of a 'Monad'--on opaque entity reflecting its environing universe--thus conceives it in a dependent microscosmic-macrocosmic relation with the latter.  In contrast, in probably the best-known alternative microcosmos-macrocosmos relation--Plato's 'wirt small'-'writ-large'--the two realms are merely isomorphic, with neither prior to the other, as is also the case when they are inversely related, or are not related at all.  One advantage that these alternatives have over Leibniz' concept is that they doe not share with it the burden, apparently undischarged, of explaining how a microcosmos can be opaque with respect to a macrocosmos, and, yet, exist as dependent on it, i. e. it suffices for them to posit the two realms as heterogeneous with respect to one another.  At minimum, merely as conceivable alternatives, they expose the arbitrariness of Leibniz' privileging of the macrocosmos, a priority that precludes the possibility of an independent genesis of the microcosmos, e. g. an ascent from the infinitely small, from which a Monad first emerges.
