The article reflects contemporary discussions on formation of ecological thinking and educational theory and praxis, all of which is related to the development of complex sciences - from two points of view: The first deals with ecological thinking with regard to meta-scientific implications of the disciplines dealing with organized complexity; the second concentrates on the relevance and impact of complexity science for transformation processes in the field of education (paradigms and institutions).

Although the term ‘education for sustainable development' (ESD) was launched more than 15 years ago, it is still interpreted in widely differing ways. One part of the scientific community avoids the concept of sustainability, others discuss whether any changes have been launched in the educational field resulting from the new concept. The article goes on to briefly summarize and contrast two different approaches in ESD, the first which defines ESD as a pluralistic tradition of environmental education and the concept of radical transformative approach calling for a paradigmatic shift in the whole educational environment.

The term sustainable development is often used without respect to what it really means. Sustainability is a necessary condition for human life in the future. It demands changes in economic systems, in our thinking and conduct. The workings and demands of the economy must be in accordance with physical conditions and laws. The world with its resources and sinks (for waste absorption) is finite, the endless material growth is impossible. Our contemporary praxis is not sustainable. The importance of ethics for obtaining the desirable motion of human behavior is obvious.

The article is focused at Fromm's nonreligious, psychologically conceived interpretation of the Jewish-Christian tradition on two potential life directions of any individual. Fromm's separation from religious practice was simultaneously compensated by an attempt to create a new, unreligious rewording of the tradition of his nation, which in many aspects stayed close to the content of Jewish tradition. It is for example apparent in his differentiation of the biophilious and necrophilious orientation of a man. A man who doesn't sensibly unfold his relation towards the world in active biophilious manifestation remains underdeveloped and his unfulfilled yearning for fulfillment in life is easily turned in a destructive direction.
