It is often claimed that in normative political theory political imagination should remain unaffected by real-world contingencies: our idea of how the world “ought to be” should be independent from how the world “actually is”. According to the practice-dependent thesis, instead, “[t]he content, scope, and justification of a conception of justice depends on the structure and form of the practices that the conception is intended to govern”. This methodological approach conceives the relationship between theory and practice as an interplay: normative (...) theory applies to practice, but practices are also able to affect the content of normative theory. In this paper, I argue that the interplay between theory and practices that the practice-dependent method generates has not been fully understood. Though it may – at a superficial look – appear as a method compliant with the status quo, I will show that this method implies an idea of political theory as an activity of continuous critical engagement. Given an extended account of the method, political imagination has boundaries but these are not fixed nor easilydefinable: the real-world fact that constrains practice-dependent principles is the point and purpose of the practice they are meant to apply to, but this fact in itself is partly shaped and critically assessed by the theorist.

From Plato to the present day, political theorists have used models of idealistic societies to think about politics. How can these idealistic models inform our thinking about political life in our non-ideal world? Not, as many political theorists have hoped, by providing normative guidance -- by showing us how things should be or where we should go. Even still, we can use these models to interpret the concepts we depend on to explain and evaluate political behavior and institutions, thereby sharpening (...) our explanations of how things work and our estimations of how to make things better. Seeing idealistic models in this light reveals a promising route to a form of political inquiry that integrates our explanatory aims and our normative aspirations. -/- (Updated: October 2024.

While discussions of the imagination have been limited in philosophy of science, this is beginning to change. In recent years, a vast literature on imagination in science has emerged. This paper surveys the current field, including the changing attitudes towards the scientific imagination, the fiction view of models, how the imagination can lead to knowledge and understanding, and the value of different types of imagination. It ends with a discussion of the gaps in the current literature, indicating avenues for future (...) research. (shrink)

Even though the philosophy of simulation is intended as a comprehensive reflection about the practice of computer simulation in contemporary science, its output has been disproportionately shaped by research on equation-based simulation in the physical and climate sciences. Hence, the particularities of alternative practices of computer simulation in other scientific domains are not sufficiently accounted for in the current philosophy of simulation literature. This article centres on agent-based social simulation, a relatively established type of simulation in the social sciences, to (...) exemplify this claim. The analysis advanced has a twofold goal. First, it shows that the philosophy of agent-based social simulation, mostly developed by practitioners themselves, is, on one hand, heavily influenced by the methodological features of agent-based modelling and by the loose and fragmented character of social theory and, on the other hand, distinctively shaped by contrasting views of what it implies to do social research with virtual or artificial societies. Second, it suggests ways in which cross-fertilisation could enrich the philosophical understanding of computer simulation both in agent-based social simulation and in the philosophy of simulation.

The main purpose of this dissertation is to examine critically and discuss the role of imagination in science and religion, with particular emphasis on its possible epistemic, creative, and meaning-making functions. In order to answer my research questions, I apply theories and concepts from contemporary philosophy of mind on scientific and religious practices. This framework allows me to explore the mental state of imagination, not as an isolated phenomenon but, rather, as one of many mental states that co-exist and interplay (...) in our cogntive architecture. Based on the philosophical discourse of philosophy of mind, four types of imagination are indentified and conceptualized: sensory, propositional, experiential, and creative imagination. These categories are then employed on five phenomena that can be found in scientific and religious environments: metaphors, models, thought experiments, aspect perception, and - in the religious case - rituals. In relation to the concept of religious "seeing" I consider how imaginings may influence visionary experiences and visualization, and compare these phenomena with cases of scientific visualization and eureka experiences. In regard to scientific and religious models, a distinction is made between, on the one hand, two notions of truth and, on the other hand, truth-independent meaning-making. In light of these categories, I differentiate between, and critically discuss, the use of imagination in doxastic, non-doxastic and fictionalist accounts. In light of this investigation, I formulate and defend the position of interactivism, which acknowledges a constant interplay between different attitudes and mental states. In my examination of rituals and scientific and religious thought experiments, special attention is given to the mental capacity to recreate the experiences that are entailed in an imagined scenario. At the end of the investigation, I consider the possible impact that my study might have on how we view science and religion as well as the dialogue bewteen these two fields. (shrink)

Typically, the imagination in thought experiments has been taken to consist in mental images; we visualize the state of affairs described. A recent alternative from Fiora Salis and Roman Frigg main...

Theoretical models are widely held as sources of knowledge of reality. Imagination is vital to their development and to the generation of plausible hypotheses about reality. But how can imagination, which is typically held to be completely free, effectively instruct us about reality? In this paper I argue that the key to answering this question is in constrained uses of imagination. More specifically, I identify make-believe as the right notion of imagination at work in modelling. I propose the first overarching (...) taxonomy of types of constraints on scientific imagination that enables knowledge of reality. And I identify two main kinds of knowledge enabled by models, knowledge of the imaginary scenario specified by models and knowledge of reality. (shrink)

This paper argues that even when simple analogue models picture parallel worlds, they generally still serve as isolating tools. But there are serious obstacles that often stop them isolating in just the right way. These are obstacles that face any model that functions as a thought-experiment but they are especially pressing for economic models because of the paucity of economic principles. Because of the paucity of basic principles, economic models are rich in structural assumptions. Without these no interesting conclusions can (...) be drawn. This, however, makes trouble when it comes to exporting conclusions from the model to the world. One uncontroversial constraint on induction from special cases is to beware of extending conclusions to situations that we know are different in relevant respects. In the case of economic models it is clear by inspection that the unrealistic structural assumptions of the model are intensely relevant to the conclusion. Any inductive leap to a real situation seems a bad bet. (shrink)

This paper begins with the assumption that the concept of risk implies an entanglement between facts and values. This is not an arbitrary assumption since it can directly be deduced from the standard notion of risk. The value-ladenness of risk raises at least two further issues: the first one concerns the scales adopted to evaluate the severity of risks; the second concerns the commensurability/comparability of risks to human health and the environment. Some additional light is shed on those issues by (...) asking what would happen if the models used in risk analysis were understood as fictions limited by the values that they can include. From this point of view, controversies on the limited scope of standard risk assessments are not only descriptive but also evaluative. Keywords: commensurability, comparability, fiction, models, risk, values. (shrink)

The notions of “ideal theory” and “nonideal theory” have become widely accepted in political philosophy. Recently, several philosophers’ have urged that ideal theory systematically produces practically irrelevant theories. Such philosophers argue that political philosophy ought move away from ideal theory in order to make the discipline more germane to the unjust real world. Call this tactic of eliminating ideal theory “Strategy.” In this paper, I argue that political philosophy would do well to abandon the ideal/nonideal distinction. Though the use of (...) INID is widespread, philosophers do not have one uniform way of drawing the distinction; of the several common ways of drawing the distinction, none is categorical. As a consequence of this ambiguity, the role that INID plays in our political philosophical theorizing has become pernicious. (shrink)

En el presente trabajo intentaré poner de manifiesto las debilidades de los argumentos dados por Contessa para sustentar, como fuente del representar, a los razonamientos subrogantes válidos por sobre los sólidos. En primer lugar, analizo ciertas ventajas epistémicas del criterio sustentado sobre los RS sólidos, evidenciando, consecuentemente, los límites del criterio estipulado por Contessa. En segundo lugar, muestro que los argumentos utilizados por Contessa para descartar el criterio instituido en los RS sólidos son deficientes, ya que, en el mejor de (...) los casos, no demuestran nada y, en el peor de los casos, o bien se comete una falacia por ambigüedad o bien se comete una petición de principio.
