The paper starts by reviewing a budget of paradoxes involving the logical properties of validity, inconsistency, and compatibility. The author's favored substructural approach to naive truth is then presented and it is explained how that approach can be extended in a very natural way so as to solve a certain paradox of validity. However, three individually decisive reasons are later provided for thinking that no approach adopting a classical metalanguage can adequately account for all the features involved in the paradoxes of logical properties. Consequently, the paper undertakes the task to do better, and, building on the system already developed, introduces a theory in a nonclassical metalanguage that expresses an adequate logic of naive truth and of some naive logical properties.engjournal article1755-0211https://doi.org/10.1017/S1755020314000045https://www.cambridge.org/core/journals/review-of-symbolic-logic/article/naive-truth-and-naive-logical-properties/EED55C87AC68F4375C75E086F40ADA46https://produccioncientifica.ucm.es/documentos/61fa8a56565bff40e6e7b757restricted access1164FilosofíaLógica simbólica y matemática (Filosofía)72 Filosofía1102.14 Lógica Simbólica
