Abstract

This writing is part of a body of reflections about the ‘researching programs’ and ‘categories’ used in philosophy, philology and linguistics to explain human language. Within this framework, several categories like Modell, Vorbild and Paradigm are covered from a descriptive sense according to the ‘Wittgenstein’ research program. From Russell’s conception of language, there is a treatment to the prescriptive aspects of Plato’s ideas and their relation to universals. Then, the universal category in the predicament act and the denotation act are linked proposing their relation with notions such as ‘knowledge’ and ‘truth’. Therefore some concerns, shared by Russell and Wittgenstein about a philosophical grammar, are pointed out for the expression of human understanding
