2026 Summer School
The End of Certainty: Conversations on the Crisis of Science and Society
7–9 September 2026, Florence, Italy
This is not a course about finding answers. It is an invitation to rethink the questions.
The summer school offers 3 days of intense reflections about Complexity, Uncertainty and Governance of Knowledge. We are living through a metacrisis: not only a failure of prediction, but a loss of the conceptual and cultural frameworks needed to integrate scientific knowledge, meaning, and ecological constraints. This Summer School will give you the opportunity to discuss with scholars who have spent decades confronting the limits of science, and what it means to think, decide, and act when certainty is not available.
First, on Day 1, participants will be introduced to the concept of Complex Adaptive Systems, systems that become something else in time, while maintaining a recognizable identity. Human societies are canonical examples. The central question to be explored will be the following: “What does remain the same when societies become something else?” and thus, how should we frame an analysis of their sustainability? Key ideas here are autopoiesis and structural coupling, holons and holarchies, introduced using simple examples to illustrate the epistemological consequences of complexity—i.e., the limits of modelling and the unavoidable coexistence of non-reducible representations of Complex Adaptive Systems across scales. Guest speaker Art Berman will examine how contemporary societies increasingly mistake models for reality itself, treating them not as provisional tools for navigating uncertainty but as stable representations of the world. He will suggest that modern knowledge lacks a coherent worldview and, at the same time, the erosion of shared narratives undermines society’s capacity to make sense of limits and change.
Next, on Day 2, participants will be guided directly to the heart of the crisis at the interface between science and policy. Starting from today’s most urgent challenges—environmental risks, technological transformations, political conflicts—we will discuss how the effective governance of these issues is challenged not by lack of data, but by the existence of irreducible uncertainty and conflicting values. In such conditions, the traditional ideal of science as a provider of certainty collapses, and Post-Normal Science is required to make processes of decision-making robust, transparent, and socially accountable—addressing situations where “facts are uncertain, values in dispute, stakes high, and decisions urgent.” In this different narrative, science is no longer a machine for producing truth, but a collective practice for navigating uncertainty. A practical example of effective tools developed at the Joint Research Centre of the European Commission will be discussed as case study.
On the last day, the conversation will address the most difficult territory of all: how societies live—or fail to live—with uncomfortable knowledge. We will show that ignorance is not simply a lack of information, but something actively produced within social systems. Why do societies resist bad news about their own future? Why do optimistic narratives persist even when evidence suggests otherwise? Through the lens of biosemiotics, identity, and socio-technical imaginaries, participants will examine the tension between what might be called “noble lies” (yes, we can) and “toxic truths” (we are in trouble). Here, scientific models give way to questions of meaning, narrative, and collective identity.
The programme concludes in an open afternoon session with our colleagues at the University of Florence and the participants of the parallel summer school on ecological macro-economics, a space for open conversation shaped by participants’ questions.

LIPHE4 Summer Schools bring together a mix of graduate students, postdoctoral fellows and professionals to transcend disciplinary boundaries, piece together the big picture of today’s most urgent sustainability problems and explore our radically uncertain future. Participants can expect both traditional lecture sessions and applied practical sessions conducted in small groups, which often extend into long-term collaborations and scientific papers. LIPHE4 Summer Schools provide an opportunity for early-career researchers to expand their research horizon and network as well as gain valuable experience “thinking outside the box” and working in transdisciplinary teams.
