This paper recognizes a specific correspondence between biological evolution and technological development and on this basis tries to set up a semioticapproach to the evolutionary phenomenon of exaptation. To do this, the existence of a historical-structural and pragmatic analogy between organs and tools is shown, which in turn implies on a communicative ground the dissolution of some of their traditional distinctive att ributes. Finally, a philosophical-analytical approach to natural and cultural functions is applied to define three types of exaptations.

This paper examines the ethological notion of ritualization from the perspective of zoosemiotic studies. Instead of moving within the horizon of traditional semiotic approaches to this phenomenon, my aim is to propose an alternative attempt of modelling based on the linguistic and semiotic concepts of context and contextuality. At the same time, the paper identifies ritualization as a case of exaptation, suggesting the extension of the context-based model within evolutionary biology and the agenda of its semiotic description, namely biosemiotics. At (...) lenght, a potential application of the model is suggested with respect to human ritualization, essentially as a means to prevent inadequate adaptationist considerations. (shrink)

John Dewey’s theory of education, despite having become a reference point for the pedagogical sciences, has been subjected to much criticism. One of the most significant attacks came from Jerome Bruner, who questioned Dewey’s principles as set forth in his “My Pedagogic Creed”.1 Bruner chose that book for criticism because it foreshadowed much of the later writing on education by the American philosopher, and he assessed the five articles of faith contained therein against the background of the deep changes that (...) had occurred in conceptions of society, social institutions, and man. Then, paralleling Bruner, Kieran Egan stressed more recently the necessity to reconsider some of Dewey’s.. (shrink)
