Dynamic Humeanism

Humean accounts of laws of nature fail to distinguish between dynamic laws and static initial conditions. But this distinction plays a central role in scientific theorizing and explanation. I motivate the claim that this distinction should matter for the Humean, and show that current views lack the resources to explain it. I then develop a regularity theory that captures this distinction. My view takes empirical accessibility to be one of the primary features of laws, and I identify features laws must have to be empirically accessible. I then argue that laws with these features tend to be dynamic. 1 The Best System   1.1 Orthodox Humeanism 2 The Best Is Not Good Enough   2.1 Laws and boundary conditions   2.2 Laws and scientific practice   2.3 An illustrative example 3 Laws and Epistemic Roles   3.1 The epistemic criterion   3.2 The epistemic role account   3.3 Scientific virtues   3.4 Applying the epistemic role account 4 Conclusion 1 The Best System   1.1 Orthodox Humeanism   1.1 Orthodox Humeanism 2 The Best Is Not Good Enough   2.1 Laws and boundary conditions   2.2 Laws and scientific practice   2.3 An illustrative example   2.1 Laws and boundary conditions   2.2 Laws and scientific practice   2.3 An illustrative example 3 Laws and Epistemic Roles   3.1 The epistemic criterion   3.2 The epistemic role account   3.3 Scientific virtues   3.4 Applying the epistemic role account   3.1 The epistemic criterion   3.2 The epistemic role account   3.3 Scientific virtues   3.4 Applying the epistemic role account 4 Conclusion
