In the past thirty years, two fundamental issues have emerged in the philosophy of science.
One concerns the appropriate attitude we should take towards scientific theories--whether …

Specifically, my theories of health and disease in Section 7.3, of etiology in Section 7.5, and
of diagnosis in Section 9.2 are based on my “Fundamentals of clinical methodology”, 1-4, in …

Publisher Summary This chapter discusses paraconsistent logics (PL) and paraconsistency.
PL are the logics of inconsistent but nontrivial theories. A deductive theory is paraconsistent …

The notions of health, illness, and disease are fuzzy-theoretically analyzed. They present
themselves as non-Aristotelian concepts violating basic principles of classical logic. A …

The purpose of this paper is to present a paraconsistent formal system and a corresponding
intended interpretation according to which true contradictions are not tolerated …

During the last two decades, we have been witnessing a growing interest as well as a
remarkable activity in connection to paraconsistent logic. So many specialized publications …

The main aim of this paper is to introduce the logics of evidence and truth LETK+ and LETF+
together with sound, complete, and decidable six-valued deterministic semantics for them …

This paper introduces the logic QLETF, a quantified extension of the logic of evidence and
truth LETF, together with a corresponding sound and complete first-order non-deterministic …

The concept of medical diagnosis is reconstructed and its syntax, semantics, and pragmatics
are analyzed. It is shown that medical diagnosis is relative to a complex diagnostic structure …

From the technical point of view, philosophically neutral, the duality between a
paraconsistent and a paracomplete logic (for example intuitionistic logic) lies in the fact that …
