The question of whether our society is facing a profound transformation is no longer relevant—we are already in the midst of it. The only question that remains is how this transformation will unfold: by disaster or by co-design? Those who do not wish to undergo change passively, and potentially in painful ways, but instead seek to co-shape it actively, are choosing sustainability. Sustainability is both a necessity and an opportunity:
A key factor in both crisis resilience and a good life (Buen Vivir) is social cohesion. Equally important is diversity, since monocultures—including economic and intellectual ones—are especially vulnerable to crises. Diversity implies not only the recognition of human difference, but above all the possibility of alternatives to a single hegemonic and unsustainable model of development. In this sense, sustainability has stood for »visions of another development« ever since the Dag Hammarskjöld Report »What Now? Another Development« (1975).
In our so-called »knowledge and information society« (Bell, 1973), there is already a vast amount of knowledge available—about problems and about possible solutions as well. There is no shortage of literature, conferences or expert debates. We know, for example, that a rapid transition away from the fossil-fuel regime of oil, coal and gas is necessary to limit global warming. Those who wish to overcome the crisis of democracy must dare to deepen and strengthen democracy. Growing social inequality calls for a fairer distribution of resources, wealth and power. And those whose decisions and activities cause ecological, economic or social harm should be held accountable for these consequences rather than being allowed to externalise them.
What we still know comparatively little about, however, is how to move from problems to solutions. This is the central question of transformation. It cannot be learned from books alone; it must be learned above all through practice—by putting ourselves on the line. We are the transformation, and the first step out of powerlessness is cooperation with others.
Transformation is, first and foremost, a process of communication. One fundamental principle applies: relationships come before content (Watzlawick et al., 2011 [1967]). The quality of relationships shapes the way in which issues are addressed. How a society communicates and organises itself has a profound influence on its relationship with the environment. Sustainability therefore implies more cooperation than competition, more community than private interest. It begins with changing social relationships. Whether a political process is sustainable often depends less on what is being pursued than on how it is pursued. Participatory forms of transformation are generally more sustainable than those imposed from above.
Since every place and every context possesses its own distinctive character, there is no universal blueprint for sustainable transformation. It should begin with exploration rather than planning, because the true experts in the specificity of a place are, first and foremost, the people who live and work there. Whereas the dominant development models of modernisation tend to treat people and nature as functional objects, sustainable transformation seeks to empower them as active subjects capable of shaping their own futures. It also depends on building new alliances: between citizens and institutions, between neighbourhoods and social movements, between humanity and nature, and beyond.
If the agora of ancient Greek democracy was an exclusive one, sustained by the exploitation of slaves, then a good life that does not come at the expense of others requires an expanded agora—one in which those others are also given a voice, including future generations and the natural world.
People do not necessarily act on what they know. Ways of thinking, habits and cultural dispositions that have developed over decades, or even centuries, cannot be changed overnight. Those who have been socialised to compete above all else and to behave as homo economicus often find it difficult to share or cooperate. A thriving democracy, by contrast, depends on a culture of trust rather than distrust. For this reason, there can be no sustainable transformation without cultural change. Such change requires an emancipated landscape of education, research, the arts and the media.
Sustainable transformation begins at the local level and should be understood and shaped as both an individual and a collective learning process. Every city, neighbourhood and village can become a space for learning, where alternatives are explored and new forms of living together are developed. Spaces that enable social experimentation, the cultivation of commons, and non-commercial rituals can strengthen social cohesion and make change a lived experience. One example is the »Day of the Good Life« (Tag des guten Lebens), which has been held annually in Cologne since 2013.
