Abstracts

James Nguyen (University of London)
“Why (at least some) idealisations aren’t false”

In order to understand how idealised models contribute to the epistemic success of science we need to understand how they, and models in general, represent. I outline the, relatively commonly held, view that modelling is an indirect enterprise: model descriptions serve to specify model systems, which in turn represent their target systems. I argue that, suitably interpreted, the idealised aspects of these model systems needn’t be understood as misrepresentations. I then discuss the upshot of this way of thinking in terms of the factivity of explanation and understanding.

Angela Potochnik (University of Cincinatti)
“Why it matters that idealizations are false”

Many of our best scientific explanations incorporate idealizations, that is, false assumptions. Philosophers of science disagree about whether and to what extent we must, as a result, give up on truth as a prerequisite for explanation and thus understanding. I propose reframing this. Factivism or veritism about explanation is not, I think, an obvious and preferable view to be given up only under duress. Rather, it is philosophically fruitful to emphasize how departures from the truth facilitate explanation (and understanding). I begin by motivating one version of the idea that idealizations positively contribute to understanding, then I make the case that it is philosophically important to emphasize this contribution of idealizations. I conclude with a positive account of what theorists about science stand to gain by acknowledging, even emphasizing, how certain departures from the truth benefit our scientific explanations.

Announcement: Warsaw Spacetime Colloquium 2020/2021 (online)

The Colloquium focuses on the foundations of spacetime physics broadly construed, and will be held fortnightly on Zoom (16:00-18:00 CET).

The program for the winter semester is the following:

  • 2 October – Carlo Rovelli (Aix-Marseille University) – “Why can we decide what we shall do tomorrow, but we cannot decide what we did yesterday? Time reversibility and the physics of an agent”
  • 16 October – J. Brian Pitts (University of Cambridge) – “Change in observables in Hamiltonian general relativity”
  • 30 October – James Read (University of Oxford) – “Shifts and reference”
  • 13 November – Karen Crowther (University of Oslo) and Sebastian De Haro (University of Amsterdam) – “The role of singularities in the search for quantum gravity”
  • 27 November – Claus Kiefer (University of Cologne) – “Time in quantum gravity”
  • 11 December – Radin Dardashti (University of Wuppertal) – “The rise and fall of scientific problems”
  • 8 January – Karim Thébault (University of Bristol) – “On the structure of time in physical theory”
  • 22 January – Vera Matarese (Univ ersity of Bern) – “Spacetime the many substances”
