ARC-1: Affinity, Reality and Communication= Experience
ARC is what we have in common with animals, we can experience things love, agree and observe, we can communicate with things and thus experience them. ARC has to do with the phenomenal world.
ARC-2: Actuality plus Reasoning and Concepts = Understanding
Actuality, not ‘scientological reality’ is accessible through reason and leads to concepts which all together leads to understanding. Understanding goes deeper than surface reality, or appearances it goes into why things are what they are. ARC has to do with the noumenal world of ideas and theta (reason, mathematics) itself.
