I deal with the issue of the environmental crisis from the perspective of a phenomenologically embedded qualitative social ontology. The first point I make is that our environment is a «personal world», and not a «naturalistic world»: a world that is experienced in the «personalistic attitude» and as such is an ontologically qualitative world, in which both natural and social entities are given to us as essentially constituted by value-qualities and meanings, and not as merely material things. The second point (...) I argue for is that our environment is also a «common-surrounding world» whose personal collectives are its essential correlate: «common-surrounding world» and personal collectives existentially depend on one another, and human persons, both individual and collective, are responsible for the existence of their environment and its entities. I apply the tools of phenomenological eidetics to the ideas of «personal world» and «common-surrounding world», and inquire into the ontologically qualitative implications that they have for our environment and its crisis.
