In this contribution I focus on perhaps the most significant and, at the same time, the most revolutionary characteristic of Tichy’s transparent intensional logic (TIL), which is procedural semantics. Despite the fact that in the second half of the last century there was already a clear need for an explication of hyperintensionality – a structual explication, if possible – hyperintensionality was defined only in a negative way. Hyperintensionality is the kind of context in which the substitution of logically equivalent expressions fails and it is necessary to have a more refined distinction of meanings than one of mere equivalence. Tichý, however, not only defined hyperintensions positively as algorithmically-structured procedures, that is TIL constructions which are assigned to expressions as their context-invariant meanings, but at the same time he showed that in the framework of this system it can hopefully adequately solve all the problems which traditional PWS semantics of possible worlds could not deal with. In this article I demonstrate that structured procedures are the central element of our communication across various cultures, specialisations and time. At the same time, however, I outline the problems which this evidently plausible conception of meaning brings with it, and I propose a solution to them.

The article Truth and Falsity of Literary Statements investigates the issue of logical values, and consequently communication related status of sentences in indicative mood occurring in works of literature. The problem is discussed with reference to theoretical assumptions of classical logic, intuitionistic logic, and other possible intensional logics as well as phenomenological concepts proposed by Roman Ingarden. In this context it is suggested that intensional systems, mainly intuitionistic logic be adequately applied to identify logical value of literary sentences. As a result, it is assumed that the logical value of literary sentences depends on the specific logical system selected; according to the standards of intuitionistic logic, literary statements are true, likely or false. In this context it seems necessary to revise Roman Ingarden’s phenomenological assumption that sentences in indicative mood in a work of fiction do not have objective point of reference. It is suggested that such sentences be recognised as false, and therefore indicative of the group of their intentional meanings as a specific model of reality which can be deemed true or false.

This paper is devoted to the brilliant Czech logician and philosopher of language Pavel Tichý (1936–1994) who, after emigrating to New Zealand in 1970 and spending half his life there as a political refugee, committed suicide shortly before returning to his alma mater, Charles University in Prague, as Chair of the Department of Logic in the Faculty of Arts. After tracing a biographical profile of the Czech logician, the paper explains some of the central ideas of Tichý’s highly original theory, called Transparent Intensional Logic, while locating it in the wider context of the analytic philosophy of language. The paper concludes by highlighting the role played by Tichý’s intensional theory in advancing various disciplines, including artificial intelligence, with the aim of shedding light on the significant contributions of the Czech logician, who has yet to gain due recognition.
