This volume offers a wide range of both reconstructions of Nikolai Vasiliev's original logical
ideas and their implementations in the modern logic and philosophy. A collection of works put
together through the international workshop Nikolai Vasiliev's Logical Legacy and the Modern
Logic this book also covers foundations of logic in the light of Vasiliev's contradictory
ontology. Chapters range from a look at the Heuristic and Conceptual Background of Vasiliev's
Imaginary Logic to Generalized Vasiliev-style Propositions. It includes works which cover
Imaginary and Non-Aristotelian Logics Inconsistent Set Theory and the Expansion of
Mathematical Thinking Plurivalent Logic and the Impact of Vasiliev's Imaginary Logic on
Epistemic Logic. The Russian logician Vasiliev was widely recognized as one of the
forerunners of modern non-classical logic. His imaginary logic developed in some of his work at
the beginning of 20th century is often considered to be one of the first systems of
paraconsistent and multi-valued logic. The novelty of his logical project has opened up
prospects for modern logic as well as for non-classical science in general. This volume
contains a selection of papers written by modern specialists in the field and deals with
various aspects of Vasiliev's logical ideas. The logical legacy of Nikolai Vasiliev can serve
as a promising source for developing an impressive range of philosophical interpretations as
it marries promising technical innovations with challenging philosophical insights.
