Abstract

The solution of the problem of the future random events truth is considered in Vasil'ev's logic. N. A. Vasil'ev graded the logic according to two levels—the level of facts, i.e. time fixed events, and the level of notions or rules, governing these facts. The mathematical construction previously suggested for imaginary Vasil'ev's logic, extends to the early variant of his logic—a logic of notions. In the paper, we investigate the meaning of problematic and uncertain assertions introduced by Vasil'ev. As a result, we developed a model of Vasil'ev's logic of facts that resolves also the truth problem of future random events. The imaginary logic has also been extended to the level of notions, and the law of the excluded eighth is gotten in it. The correspondence between Vasil'ev's terms "some" and "all" and modern quantifiers is discussed.
