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)
