 Saatsi 2017 criticizes Lyon and Colyvan 2008 by questioning the conclusiveness of the appeal to phase spaces in bringing about explanations which would allow the deployment of an enhanced indispensability argument. After proposing a strengthening of the indispensability argument by appealing to attractors in dynamical system theory, he concludes that understanding how explanations work in dynamical system theory undermines the Platonist use of the enhanced indispensability argument.
