This characterization is admittedly bold, given the diverse theoretical roots of paraconsistency and the contested nature of its interpretation. Accordingly, our discussion addresses the topic from both historical and formal perspectives, emphasizing key moments in the development of paraconsistent logic within the Latin American context. Particular attention is given to the extensive and systematic work of Newton C.A. da Costa in Brazil, whose contributions played a central role in shaping paraconsistent logic as a mature and influential field. In addition, we briefly explore how paraconsistent logic challenges classical logic to reconsider its conclusions in light of paraconsistent principles. Ultimately, this paper seeks to situate paraconsistency within the broader context outlined above, examining its impact and identifying its key theoretical and practical features in contemporary philosophical thought.</p></abstract><trans-abstract xml:lang="ru"><p>В исследовании представлен обзор параконсистентной логики, прослеживается ее историческое происхождение и развитие в рамках того, что можно назвать латиноамериканской школой параконсистентности. Такая характеристика, по общему признанию, является смелой, учитывая различные теоретические корни параконсистентности и спорный характер ее интерпретации. Соответственно, в нашем обсуждении эта тема рассматривается как с исторической, так и с формальной точек зрения, подчеркивая ключевые моменты в развитии параконсистентной логики в латиноамериканском контексте. Особое внимание уделяется обширной и систематической работе Ньютона К.А. да Косты в Бразилии, чей вклад сыграл центральную роль в формировании параконсистентной логики как зрелой и влиятельной области знаний. Кроме того, мы кратко рассмотрим, как параконсистентная логика бросает вызов классической логике, заставляя ее пересмотреть свои выводы в свете параконсистентных принципов. В конечном счете эта статья направлена на то, чтобы поместить параконсистентность в более широкий контекст, описанный выше, исследуя ее влияние и выявляя ее ключевые теоретические и практические особенности в современной философской мысли.</p></trans-abstract><kwd-group xml:lang="en"><kwd>paraconsistency</kwd><kwd>contradiction</kwd><kwd>triviality</kwd><kwd>Brazilian school of paraconsistency</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>параконсистентность</kwd><kwd>противоречие</kwd><kwd>тривиальность</kwd><kwd>бразильская школа параконсистентности</kwd><kwd>латиноамериканская философия</kwd></kwd-group><funding-group/></article-meta><fn-group/></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Arruda AI.
