In GOL it is assumed that the world is organized into strata, which
are again organized into layers. This is based on poli1. Level
are strata or layers. There are
at least three strata: a material stratum, a mental or psychological
stratum and a social stratum. Levels are characterized by the
categories they use, and those categories imply a certain granularity,
so that granularity is a derived concept.
The mental and the social strata are founded in the material
stratum. This basically means that the categories and entities of the
mental and the social strata can be reduced to categories of the
material stratum, but only with a loss of information, so the reverse
is not possible. The relation between the mental and the social
stratum is still unclear. Granularity and levels are discussed in
section 5.2.11.
