“Dialogue” has become one of the core notions to address fundamental issues of present time, such as cultural and religious plurality, and more generally to come to understand as well as to practically deal with diversity and differences. This issue of Teoria collects contributions, both invited and selected by means of an international Call for Papers, addressing dialogue from different perspectives and disciplines. The aim of the issue is to provide the reader with a selection of current theoretical and practical perspectives on dialogue, and to offer a broad picture of the complex range of definitions, meanings and practices connected to it, also giving voice to critical and intersectional positions.
After a reinterpretation of dialogue in classical Greece (Serra), some contemporary perspectives are offered to connect the reflection on authors with that on general topics, such as the fundamental notion of subject (Falzon), the relationship between dialogue and power (Monceri) and the dialogic encounter with the beyond-human world (Keating). The subsequent articles are devoted to some dialogue theories as elaborated by important authors, highlighting both their epistemological foundations (Biondi, Lillebø) and their implications for relevant fields to which dialogue is currently applied, such as interreligious dialogue (Vendra, Tumminelli). The last two articles address some relevant aspects of the dialogical practice (Brivio and Bertolino, Plass).
