Summary

Sydney Doering presents a philosophical argument that experiments can function as models in biology, playing a similar epistemic role to abstract models. She builds on van Fraassen’s view of representational activity, Giere’s view of theories as families of models, and Weber’s view of experimental models. She argues that experiments become models through intentional use by agents, who highlight salient resemblances and non-resemblances to target systems. Using the yeast multicellularity experiments by Ratcliff and Travisano as a case study, she illustrates how an experimental system can serve as an open-ended model, allowing exploration of biological possibilities that abstract models may miss. The talk emphasizes the importance of context, intentionality, and the unique benefits of using living systems as models, such as retaining complexity and enabling open-ended evolution. The main takeaway is that experimental models can contribute to theorizing in ways similar to abstract models, and their open-endedness makes them particularly valuable for investigating lesser-known biological dynamics.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides a valuable contribution to the philosophy of science by synthesizing existing views and proposing a novel intentional modeling view. The argument is well-structured, moving from theoretical foundations to a concrete example. The use of the multicellularity experiment effectively illustrates the concepts. The speaker addresses potential objections, such as the role of non-resemblances and the relationship between experimental and abstract models in providing scientific understanding. The reasoning is clear and persuasive, though some points could be further developed, such as the precise epistemic benefits of open-endedness.

Scientific Rigor, Source Quality, Title Accuracy

The talk demonstrates scientific rigor by grounding the argument in established philosophical frameworks (van Fraassen, Giere, Weber) and a well-known experimental study (Ratcliff & Travisano). The sources are appropriately cited in the presentation, though not all are explicitly listed in the description. The title accurately reflects the content. The talk is an expert opinion presented at a graduate conference, which is appropriate for the context. The argument is coherent and well-supported, though it would benefit from further peer review and publication.

Dissenting Sources

  • Frigg, R., & Nguyen, J. (2020). Scientific Representation. — This work offers a different perspective on scientific representation, potentially challenging the view that experiments can be models in the same way as abstract models.

Contribution & Novelties

The talk offers a novel synthesis of existing philosophical views to argue that experiments can function as models in a way that is epistemically comparable to abstract models, with unique benefits due to their open-endedness and complexity. It emphasizes the intentional role of agents and the importance of context in modeling, which is often overlooked. The case study of multicellularity evolution provides a concrete illustration.

Pour aller plus loin :

  • Surrogative reasoning — A key concept in modeling, directly relevant to the talk’s discussion of experiments as surrogates.
  • Experimental evolution — The method used in the case study, relevant to understanding the experimental model.
  • Multicellularity — The biological phenomenon investigated, providing background on the target system.
