The International Pre-Biennales of Practical Philosophy give us the occasion of a particular reflection on the possible forms of relation between practical philosophy and fields of thinking, expression, praxis being non philosophical per se and thus, by means of a such research, as it is unfolded, of an intensification of the reflection on possible conceptions of practical philosophy today. Through a series of specially designed workshops or talks, the Pre-Biennales will insist more on some aspects of this thematic field by giving the floor to researchers and artists working in various places with various tools and ways.
