The intellectual legacy of Roman Ingarden, an eminent Polish philosopher, is a vast body of work covering many academic disciplines and deserves an in-depth and a non-homogeneous study. The monograph Roman Ingarden's Heritage in Multicultural Investigations offers the reader an interdisciplinary journey through numerous aspects of linguistics, literary studies, social communication and media sciences. On the one hand, this volume includes several papers exploring multicultural issues of translation, linguistic interactions, formulation of textual messages and the publication of literary works in multidimensional environments. On the other hand, a collection of further texts describes the nature of today's media, their function and role in a multicultural world and beyond. The 130th anniversary of Roman Ingarden's birth calls for a lively debate to determine the actual role that contemporary interdisciplinary studies play in today's multicultural world. This book is a response to that call.
