Nikolai Aleksandrovich Vasiliev (1880-1940), Professor of Kazan University (Russia), was a seminal thinker, philosopher, rhyme maker and logician, who outpaced his time and influenced development of logical ideas far outside his own country. He is known for having pioneered the logic with a consistent logical system in the form of syllogistics theory basing upon a contradictory ontology, thus having emerged as the father of paraconsistent logic. What is more, though short (four papers published in 1910-13) his scientific legacy underpins fruitful ideas of the modern logic. Some researches also trace in his writings the elements of the many-valued and modal logic as well. All of the above compels one to regard Nikolai Vasiliev along with Jan Łukasiewicz as one of the precursors of non-classical logic.
