In the previous chapters, we dealt with a concrete critique of the SDGs after first presenting and explaining the critical framework, neopragmatism as a theoretical-conceptual framework, the possible balancing of the individual and society based on the concept of life chances and considering the dual structure of individual striving for options and social ties, and the concept of sustainability in its historical contexts. In order to gain an integrative understanding of sustainability and, if possible, to conceptualize and operationalize it, the aforementioned aspects must be related to each other in their diversity and synthesized. As shown in the previous chapters, reductionist models should also be avoided in this question. The integrative perspective is, on the one hand, Popper's model of the three worlds and, on the other hand, a metatheoretical perspective that focuses more on the development of orientational knowledge than on dispositional knowledge, as is the consequence for the implementation of the SDGs. In this chapter, we will first address fundamental considerations regarding life chances and sustainable development before turning to conceptual considerations.
