Larmer* Received: 24 May 2018 / Accepted: 4 September 2018 Abstract: Contrary to proponents’ claims, methodological naturalism is not metaphysically neutral. Consequently, its acceptance as a prac- tice requires justification. Unfortunately for its advocates, attempts to justify it are failures. It cannot be defended as a definition, or a self-imposed limitation, of science, nor, more modestly, as an in- ductively justified commitment to natural causes. As a practice, it functions not to further scientific investigation, but rather to impose an explanatory straitjacket.
