If Si fails to serve this general project, it betrays or otherwise offends Sc. We presuppose that Si is a member of Sc. Si's symbolic or somatic disrespect can lead to catastrophe for Sc, because it can call down W2's wrath, barring Sc from reaching W3. Si is in principle dangerously unreliable. Therefore, the general state of affairs W1-W2 becomes dramatically indeterminable, so the community will have to have access to Si's intimate behavior, thoughts, and emotional attitudes and to control them in order to ensure its own 'salvation'.
Monotheisms have to test the quality of faith and devotion of every believer.
They dig into their believers' souls, and are never contented by mere ritual service. A 'logic' along these lines might also explain why monotheisms develop intolerance, fundamentalism and 'holy warfare'. Only the imminence of death can reveal the true quality of individual devotion, and this quality is primarily expressed by the courage of the warrior. Secondarily, it can, of course, be expressed by the perceivable signs of hatred felt for the collective enemy. Si-Sg is interpersonal, so Si can have experiences of spiritual contact with Sg without ecstasy, and Sg can then be interpreted as capable of reasoning, experiencing beauty, and committed to justice.
