97Psychologism and metalogicSynthese 137 (1-2). 2003.This paper examines two arguments againstpsychologism advanced by Frege andHusserl. The first argument says that thelaws of logic cannot be justified by thelaws of psychology, because the formerand a priori and certain, but the latterare probable only. The second argumentpoints out that the status of logicallaws as universal principles of thinking isnot intelligible on the psychologisticinterpretation of logic. The author tries toshow how to examine both arguments bymetalogical devices.

Further comments and remarks concern the (partly analogous) beginnings of the work on the decision problem, Gödel?s theorems and related matters, and general metamathematics. An appendix summarizes a text by the author on completeness and categoricity

71Aletheia in Greek thought until AristotleAnnals of Pure and Applied Logic 127 (1-3): 339-360. 2004.This paper investigates the concept of aletheia in ancient philosophy from the pre-Socratics until Aristotle. The meaning of aletheia in archaic Greek is taken as the starting point. It is followed by remarks about the concept of truth in the Seven Sages. The author discusses this concept as it appears in views and works of philosophers and historians. A special section is devoted to the epistemological and ontological understanding of truth. On this occasion, influential views of Heidegger are …Read more

2Scepticism and logicHistory of Philosophy & Logical Analysis 1. 1998.This paper offers a logical analysis of scepticism. It is shown that dogmatism, academism and scepticism as characterized by Sextus Empiricus in Outlines of Pyrronism form a variety of views which can be ordered by an interpretation of the classical logical square. In particular, scepticism appears as a conjunction of the negations of dogmatism and academism. The next problem concerns the logic proper for scepticism. Logic based on a dual of the consequence operation is proposed as satisfying in…Read more

16The Cognitive Relation in a Formal SettingStudia Logica 86 (3): 479-497. 2007.This paper proposes a formal framework for the cognitive relation understood as an ordered pair with the cognitive subject and object of cognition as its members. The cognitive subject is represented as consisting of a language, conequence relation and a stock of accepted theories, and the object as a model of those theories. This language allows a simple formulation of the realism/anti-realism controversy. In particular, Tarski’s undefinability theorem gives a philosophical argument for realism…Read more
