Models and Idealizations in Science

This post is by Alejandro Cassini (University of Buenos Aires) and Juan Redmond (University of Valparaiso) who recently edited Models and Idealizations in Science: Artifactual and Fictional Approaches (Springer, 2021). Here they present the book.


This book is intended both as an introduction to the philosophy of scientific modeling and as a contribution to the discussion and clarification of two recent philosophical conceptions of models: the artifactual and the fictional views. 

The first chapter provides a rather elementary but fairly complete and extensive introduction to the present state of the philosophy of scientific models. It also offers a brief historical narrative of the rise and the early development of the philosophy of scientific models since the middle of the 20th century.

The commented bibliography at end of the book complements this narrative by offering a classified list of the main relevant books on models and idealizations in science preceded by short commentaries intended to guide the search for further readings on the different topics. 

The rest of the book is a collection of ten previously unpublished articles by different philosophers of science, who deal with a wealth of topics concerning models and idealizations in science. Among the many issues they address, it can be mentioned the artifactual view of idealization, the use of information theory to elucidate the concepts of abstraction and idealization, the deidealization of models, the nature of scientific fictions, the fiction view of models defended from its critics, the structural account of representation and the ontological status of structures, the role of surrogative reasoning with models, and the use of models for predicting and explaining physical phenomena.

The pervasive use of models and idealizations in all sciences was slowly, and lately, acknowledged by philosophers of science since the last two decades of the twentieth century. By contrast, during the first two decades of the twenty-first century, there was an explosion of different kinds of philosophical studies regarding scientific modeling. 

However, philosophers of science have not yet reached an agreement concerning the precise terminology to be used in dealing with scientific models and, for that reason, the vagueness and ambiguity of some key terms, such as “model system”, “target”, “abstraction”, and “idealization”, among many others, are still a hindrance for the communication between philosophers of different persuasions. 

In turn, the ubiquitous concept of representation, one of the most elusive in Modern philosophy, has defied the many attempts at elucidation in the many philosophical disciplines in which it was employed, such as the philosophies of language, mind, and art. 

This book also aims at contributing to the clarification of these and other concepts that belong to the toolkit with which philosophers of science address such questions as what models are, what they are used for, and how they represent -if they do it- the phenomena we encounter in the real world.

Delusions in the DSM 5

This post is by Lisa Bortolotti. How has the definition of delusions changed in the DSM 5? Here are some first impressions. In the DSM-IV (Glossary) delusions were defined as follows: Delusion. A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith). When a false belief involves a value judgment, it is regarded as a delusion only when the judgment is so extreme as to defy credibility.

Motivated Reasoning in Science

Today's post is by Josh May (University of Alabama, Birmingham). In this post, he talks about one of his papers published in Synthese and entitled " Bias in Science ". Josh May Much discussion of the replication crisis in science has focused on the social sciences, particularly psychology. A common narrative is that the social sciences are particularly susceptible to powerful biases, such as moral and political ideology. I argue instead for a parity thesis: all areas of science are subject to bias, through the general psychological mechanism of motivated reasoning . This provides a unified framework for understanding how values influence the entire scientific enterprise. The scientific process involves numerous decisions that can be influenced by one's values--including moral, political, and prudential values--which manifest as goals or motivations. A researcher wants badly, say, to publish in a prestigious journal in order to either advance her career or maintain ...

Models of Madness

In today's post John Read  (in the picture above) presents the recent book he co-authored with Jacqui Dillon , titled Models of Madness: Psychological, Social and Biological Approaches to Psychosis. My name is John Read. After 20 years working as a Clinical Psychologist and manager of mental health services in the UK and the USA, mostly with people experiencing psychosis, I joined the University of Auckland, New Zealand, in 1994. There I published over 100 papers in research journals, primarily on the relationship between adverse life events (e.g., child abuse/neglect, poverty etc.) and psychosis. I also research the negative effects of bio-genetic causal explanations on prejudice, and the role of the pharmaceutical industry in mental health. In February I moved to Melbourne and I now work at Swinburne University of Technology.  I am on the on the Executive Committee of the International Society for Psychological and Social Approaches to Psychosis and am the Editor...
