Abstract
Along with the cultural interest in spirituality and mysticism in their various dimensions and meanings, which has been growing unabated for decades, there is a need for in-depth philosophical and theological reflection on the commonly referred to as mystical experience – an experiential dimension of religious life. In search of a theoretical elaboration of the phenomenon of human mystical life, this paper analyses the views of five Polish philosophers: Mieczysław Gogacz, Piotr Moskal, Jan A. Kłoczowski, Stanisław Judycki and Leszek Kołakowski. Their publications sought to answer questions about the nature of mystical experience and its ontic and epistemic conditions and characteristic structural elements. Particular attention was also paid to the context of religious life in which this kind of experience usually occurs, as well as to the fundamental concepts of mysticism as both practice and doctrine.
