The occasion to prepare the present volume is the 65th birthday anniversary of Professor Jerzy Kmita — a co-founder of the Poznan school of philosophy of science, an author of historical epistemology and of the socio-regulative conception of culture, developed in the second half of the seventies in parallel to the idealizational theory of science, non- Marxian historical materialism and unitary metaphysics.

During his more than thirty years long period of professional activity in the Institute of Philosophy, and then in the Institute of Cultural Studies of Adam Mickiewicz University in Poznan, Jerzy Kmita has gathered around himself a wide group of collaborators and disciples. Some of them have carried out research, inspired directly or indirectly by his conceptions. These conceptions function not only in the field of philosophy, but in other domains of the humanities, ethnology and cultural anthropology, history, sociology, linguistics, psychology and pedagogy.

I would like the present book to be a testimony of an original and still lively philosophical thought, a testimony of inspiration as well as of critical discussion with that thought, and — most importantly — a ferm for a further reflection about the shape and tasks of contemporary philosophy and the humanities. The text of its “protagonist” which closes the volume explicitly invites to such a philosophical conversation.

I want to thank to Professor Leszek Nowak for his initiative to publish this volume as well as for his editorial help.
