The issue is dedicated to the concept of negativity which is currently in the center of philosophical discussion. The articles take different positions on the role and value on negation in thought, but they all agree on the undeniable importance of denying. From the study of idyosincratic declinations and tropes, philosophy returns to simpler and at the same time more dramatic logical concerns. How to deal with the unwanted past, how to carve a space of subjectivity in the sea of information, and where to derive the negative force to do it? The authors search negativity in different loci, such as theatre, literature, animal nature; some criticize it, some praise, some see it as a critical, others, as an attacking violent power. All of this taken together gives a great introduction to contemporary thinking.
