As it is broadly accepted, typical uses of demonstratives are accompanied by demonstrations. The concept of demonstration, however, manifests the action–product ambiguity analogous to that visible in the opposition between jumping and the resulting jump, talking and the resulting talk or crying and the resulting cry. It is also a heterogeneous concept that enables demonstrations to vary significantly. The present paper discusses action–product ambiguity as applied to demonstrations as well as the heterogeneity of the latter. An account that acknowledges ambiguity (...) and heterogeneity of demonstrations is sketched in the paper. It is argued that it has a rich explanatory and descriptive potential. (shrink)

The paper aims to add contextual dependence to the new directival theory of meaning, a functional role semantics based on Kazimierz Ajdukiewicz’s directival theory of meaning. We show that the original formulation of the theory does not have a straight answer on how the meaning of indexicals and demonstratives is established. We illustrate it in the example of some problematic axiomatic and inferential directives containing indexicals. We show that the main reason why developing the new directival theory of meaning in (...) this direction is difficult is that the theory focuses on the notion of a sentence (and not the notion of an utterance). To add the latter notion to the theory, we introduce the idea of admissible contextual distribution being an interpretation of the hybrid expression view on indexicals and demonstratives. We argue that this idea introduces a small but important modification to the concept of language matrix and gives way to define two distinct concepts of meaning: for an expression type and for a use of an expression type.

Leon Koj napisał w zakończeniu do Problemów semiotyki logicznej, że nie sposób sobie wyobrazić semiotyki w Polsce bez Jerzego Pelca. Można opinię tę rozumieć tak, że Jerzy Pelc wywarł na semiotykę polską wpływ, bez którego to, co w niej najlepsze, nie przybrałoby nigdy formy rozwiniętej, nie ujrzałoby światła dziennego oraz nie znalazłoby odbicia w dydaktyce uniwersyteckiej. Jest to opinia trafna, a rozprawy zawarte w niniejszym – poświęconym Jerzemu Pelcowi – tomie Studiów Semiotycznych są oznakami tego wpływu.
