The author defends the idea of the ontological founding of environmental ethics. He recognises the need for a new morality that can foreshadow the biophile transformation of culture, but at the same time he knows that this morality may actually develop during the course of the transformation itself. He presents the view that the relation of man to nature is mediated not only by the relevant culture, but also by its hidden spiritual grounding, which determines the character of culture, both spiritual and material. Today’s culture finds itself in crisis because its predatory spiritual grounding is leading it to its own ruin. A biophile change in this grounding is therefore the condition for the emergence of a more sustained biophile culture. However, even if we recognise the ontological grounding of ethics, this does not necessarily mean that we fully understand the superior subjectivity of nature, nor that we recognise the higher moral principle in the relation of culture to the Earth. The Author therefore, albeit schematically, presents his evolutionarily-ontological concept of man, nature and culture., Josef Šmajs., and Obsahuje poznámky a bibliografii
