The Anthropocene, understood from the perspective of the creators of Earth System Science and IPCC, calls for global governance, which tends to be understood as an epistocratic, technocratic affair leaving little room for reflective rationality and politics in the agonistic sense. Using the republican repertoire, I argue that global governance thus understood is actually the last thing we need. I suggest that global environmental institutions ought to be based on ‘constitutional republicanism’. Key elements of this approach are a Machiavellian appreciation (...) of discord, agonism and ‘the political’, combined with a realistic assessment of the very diverse interests at stake in global climate politics, hence very diverse ideas about the benefits and burdens of specific global environmental strategies; and institutions based on ideas uniquely developed by republicans from Machiavelli to Mouffe allowing for human and science’s fallibility on the one hand, irreducible moral and political diversity on the other.

The central question of this thesis is how one can learn about particular targets by using models of those targets. A widespread assumption is that models have to be representative models in order to foster knowledge about targets. Thus the thesis begins by examining the concept of representation from an epistemic point of view and supports an account of representation that does not distinguish between representation simpliciter and adequate representation. Representation, understood in the sense of a representative model, is regarded (...) as a success term. That is, a representative model is one relatum in a relation of adequate representation (Chapter 2). When a representative model represents a target, it allows users of this model to learn something about the target. It is argued that a representative model has this epistemic function because it shares relevant features with the target. This presupposes a similarity view of representation. Similarity views of representation face serious objections, which will be rebutted (Chapter 3). One way of spelling out a similarity view of representation is to defend an indirect view of representation. In this thesis, which does not argue for an indirect view, it is assumed that the indirect view is a good option, if not the best, for articulating the similarity view. It is demonstrated how such an indirect view can be expanded to account for cases of technological modeling. A case study in bioengineering is used to show that the indirect view of representation must acknowledge a distinction between two directions of fit in relations between vehicles and targets. In this context the notion of design is interpreted as a relation between a vehicle and a target, thereby connecting ideas from philosophy of science with ideas from philosophy of technology (Chapter 4). Fictionalist accounts of models are intended to tackle the issue of the ontology of models. In this thesis, however, two prominent fictionalist accounts are discussed from an epistemological point of view in light of the central question regarding how one can learn about targets by using models. This question is addressed from the standpoint of Waltonian fictionalism. The result of the discussion is that the two discussed Waltonian fictionalist accounts cannot sufficiently answer the question. These accounts are criticized for their inability to deliver a satisfactory epistemology of representation (Chapter 5). Although Waltonian fictionalism is criticized, the present thesis also shows that the foundational theory of Waltonian fictionalism, the theory of make-believe can nevertheless be used to account for the distinction between projections and predictions that is made by the Intergovernmental Panel on Climate Change (Chapter 6).

Climatologists have recently introduced a distinction between projections as scenario-based model results on the one hand and predictions on the other hand. The interpretation and usage of both terms is, however, not univocal. It is stated that the ambiguities of the interpretations may cause problems in the communication of climate science within the scientific community and to the public realm. This paper suggests an account of scenarios as props in games of make-belive. With this account, we explain the difference between (...) projections that should be make-believed and other model results that should be believed. (shrink)

Fake research produces results that are invalid from the start. I take such research to be characterised by three jointly sufficient features. It is severely methodologically defective, and the relevant defects support certain nonepistemic (social, political, economic) interests and objectives, while the relevant objectives typically concern the interference with attempts at political regulation. I deal with two kinds of claimed fake research. One is agnotological ploys in which scientific dissent is created by interested parties from industry or politics in order (...) to support their own partisan goals. Another one is the populist antiscience movement that suspects fake research in the scientific mainstream. I suggest three remedies to reduce or eliminate the impact of fake research: disclosing fallacies, improving the understanding of scientific methods, and distinguishing more clearly between science and politics in political decision-making.
