In constructing the three-valued logic, Jan Łukasiewicz was highly inspirited by the Aristotelian idea of logical contingency. Nevertheless, we can construct a four-valued logic for explicating the Stoic idea of logical determinacy. In this system, we have the following truth values: 0 ('possibly false), 1 ('necessarily false'), 2 ('possibly true'), 3 ('necessarily true'), where the designated truth value is represented by the two values: 2 and 3.(original abstract)
