Getting Serious about Shared Features

Area of Science:

• Philosophy of Science
• Scientific Modeling
• Epistemology

Background:

• Michael Weisberg's "Simulation and Similarity" proposes a similarity-based account of the model-world relation.
• This account posits that models are successful due to shared features with their targets.
• A key challenge is defining "shared features" and their contribution to epistemic success.

Purpose of the Study:

• To critically evaluate Weisberg's similarity-based account of the model-world relation.
• To explore different interpretations of "shared features" within Weisberg's framework.
• To propose a revised, pluralistic account to address existing challenges.

Main Methods:

• Analysis of Weisberg's feature-sharing account.
• Examination of three potential concretizations of shared features: identity, quantitative closeness, and similarity.
• Development of a pluralistic revision of the similarity-based account.

Main Results:

• Each of the three concretizations of shared features faces significant challenges.
• The current account leaves ambiguity regarding how feature-sharing leads to epistemic success.
• A pluralistic revision offers a potential solution to these challenges.

Conclusions:

• Weisberg's account requires further clarification on the concept of shared features.
• The proposed pluralistic revision may enhance the account and offer new insights into the model-world relation.
• A more robust understanding of the model-world relation is crucial for scientific epistemology.
