 The particle rules determining the possible interaction of logically constant terms and modal operators in the standard framework (see  Section 2)  are replaced in the Immanent Reasoning framework by synthesis and analysis rules in order to take the local reasons into account. The rules for the logical constants presented here will determine interaction for producing local reasons appropriate to the logical constant at stake (synthesis rules), or for extracting local reasons embedded in more complex local reasons in a way that is characteristic of the constant at stake (analysis rules).
