 An account that is similar in spirit and likewise unifies Peirceanism and Ockhamism is the transition semantics presented in Rumberg (2016). The novel feature of this framework is that possible courses of events are successively built up from local future possibilities: they are viewed as possibly non-maximal, downward-closed chains of transitions, where each transition specifies a possible direction at a branching point. Incomplete possible courses of events become available as well, which can then be extended towards the future, and the language contains, in addition to temporal and modal operators, a so-called stability operator, which allows one to capture how the truth value of a formula about the future at an instant changes in the course of time. Peirceanism and Ockhamism result as limiting cases by restricting the range of admissible courses of events to the empty set of transitions and maximal chains, respectively. For details, see Rumberg (2016; 2019) and Rumberg and Zanardo (2019). A brief overview is presented in the supplementary document:
