Polymorphous concepts / trans. from Engl. by A. V. Nekhaev, I. N. Nekhaeva

The article attempts to clarify the criteria for Ryle’s class of polymorphous concepts. Ryle calls paradigmatic examples of the class such concepts as working and thinking. A common characteristic feature of polymorphous concepts is that in propositions of the form ‘P performs X’ one can always substitute a kind of specific activities in place of X, but there no one kind of activity every case of which is necessarily X-ing.
