Transparent intensional logic
and logic of imperatives

October, 17-18, 2011

17.10.2011, 13.15-14.45, Kotarbiński room:

Transparent intensional logic: an introduction
The aim of the talk is to present the core of TIL, Pavel Tichý’s transparent intensional logic, and its essential applications. We begin with motivations (e.g. hyperintensional phenomena) for the adoption of the key notions of TIL and its crucial distinctions (e.g. constructions vs. functions). Then we expose the core of the apparatus (constructions, type theory, deduction), explaining and commenting each its part. Finally, we move to applications, especially those in the field of natural language (analysis of meaning) and several important philosophical notions (e.g. conceptual systems).

Transparent intensional logie as logie of imperatives
Though no part of the current research within the framework of transparent intensional logie, TIL, is actually called ‘deontic logic’, ‘action logic’ or ‘logic of imperatives’, TIL has a potency to develop, or to already be, such logic. It may well evolve from Tichý’s and Oddie’s earlier works (published in 1980-83) and Kuchyňka’s actual work on deontic phenomena (to be published). Our talk concentrates on three topics. 1. (Tichý’s) analysis of tenses (and temporal discourse) and episodic verbs (including also perfect/imperfect verbs), which concerns ‘working place’ of agents, their actions and norming of their actions. 2. (Tichý’s and Oddie’s) logic of ability, freedom and responsibility, which focuses on restrictions in performing an action and conseąuences of an action. 3. (Kuchyňka’s) analysis of norming acts and related deontic phenomena, including analyses of imperative sentences.
