A new kind of 'dialectogram', for a 'tetradic <<monad>>-ic dialectic', modeling the leading, "Giant Impact" hypothesis-cluster as to how the present Earth/Moon System-unit was formed, has recently posted to the www.dialectics.org Glossary Page.
The 'dialectical-mathematical meta-model' depicted in this 'dialectogram' uses a 'Tetradic' Seldon Function Equation, and describes at the individual object/individual unit/individual <<monad>> level, rather than at the <<arithmos>> of <<monads>>, or categorial, level, unlike any dialectical model that we have presented previously.
These differences necessitate a re-interpretation of the epoch 1 'cumulum' of that Seldon Equation, grasping it as a 'meta-temporal summarization', i.e., as a summary overview of a natural-historical process, representing all of the major past 'ontological/<<monad>>-ic meta-states' of that process, as well as its present 'meta-state', but not just its present 'meta-state'.
This is because that 'cumulum' contains terms for <<monads>> that no longer exist in the present Earth/Moon System-unit -- past-existent, past-extant <<monads>> that have "disappeared into" the present system-<<monad>>, and which, hence, are no longer extant, in the present.
I have also posted this text+<<monad>> below, for your convenience.
