The definition of the lowest common denominator of philosophical practices is widely debated: what is the philosophical core that allows us to distinguish them from other activities? Also, is it possible to identify a methodical peculiarity in philosophical practices? Indeed, many philosophical practitioners refer to dialogue as the specific philosophical character marking their professional activity. This statement, which as such is rather naive, is obviously somewhat problematic. However, philosophical practitioners stress the λόγος of dialogue. In addition to investigating how the (...) dialogue is understood in the different philosophical practices, this contribution aims at enhancing the διά, the "between" of dialogue. This dimension, in fact, may be a possible theoretical framework within which to understand philosophical practices as a whole. (shrink)
