About this topic
Summary The best known Best Systems Account of Laws of Nature is often referred to as the Mill-Ramsey-Lewis account. All three philosophers have formulated versions of it where David Lewis's is the most sophisticated. It says, roughly: Suppose you knew everything about the past, present, and future, all facts, all events, and you organised your entire knowledge as simply as possible in various systems. The statements in these systems must mention natural properties only. A contingent generalisation is, then, a law of nature if and only if it appears as an axiom or theorem in the one system that achieves a far better combination of simplicity, strength and fit than any of the other competing systems. To have strength is to bear a great deal of informational content about the world; to be simple is to state everything in a concise way, not to be redundant, etc., to fit is, especially for the probabilistic laws, to accord as much as possible with the actual outcomes of world history.
Key works The original Best System Analysis is in: Lewis 1973 (pp.73-77); and Lewis 1999 (esp. pp. 8-55 and 224-247). Versions of it that are discussed under the heading Better Best Systems can be found here: Cohen & Callender 2009Schrenk 2006.

    What is the Significance of the Intuition That Laws of Nature Govern?1.Susan Schneider - 2007 - Australasian Journal of Philosophy 85 (2):307-324.
    Recently, proponents of Humean Supervenience have challenged the plausibility of the intuition that the laws of nature ‘govern’, or guide, the evolution of events in the universe. Certain influential thought experiments authored by John Carroll, Michael Tooley, and others, rely strongly on such intuitions. These thought experiments are generally regarded as playing a central role in the lawhood debate, suggesting that the Mill-Ramsey-Lewis view of the laws of nature, and the related doctrine of the Humean Supervenience of laws, are false.

    Idealization and the Laws of Nature.Billy Wheeler - 2018 - Switzerland: Springer.
    This new study provides a refreshing look at the issue of exceptions and shows that much of the problem stems from a failure to recognize at least two kinds of exception-ridden law: ceteris paribus laws and ideal laws. Billy Wheeler offers the first book-length discussion of ideal laws. The key difference between these two kinds of laws concerns the nature of the conditions that need to be satisfied and their epistemological role in the law’s formulation and discovery. He presents a (...)

    Humeanism, Best System Laws, and Emergence.Olivier Sartenaer - forthcoming - Philosophy of Science.
    To this day, debates on ontological emergence have been almost exclusively carried out within non-humean power-based or law-based metaphysics, the main underlying stake being indeed whether or not irreducible causal powers, or irreducible governing laws, can happen to come into being under specific circumstances. It is therefore unsurprising that humeanists themselves never felt that attracted by emergence, consistently with Lewis’ own dismissal of "suchlike rubbish". In the present paper, I argue, contrary to this received wisdom, that humeanism and ontological emergence (...)

    Dynamic Humeanism.Michael Townsen Hicks - 2018 - British Journal for the Philosophy of Science 69 (4):983-1007.
    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 (...)

    Comparing Systems Without Single Language Privileging.Max Bialek - manuscript
    It is a standard feature of the BSA and its variants that systematizations of the world competing to be the best must be expressed in the same language. This paper argues that such single language privileging is problematic because it enhances the objection that the BSA is insufficiently objective, and it breaks the parallel between the BSA and scientific practice by not letting laws and basic kinds be identified/discovered together. A solution to these problems and the ones that prompt single (...)

    Humean Laws, Explanatory Circularity, and the Aim of Scientific Explanation.Chris Dorst - forthcoming - Philosophical Studies:1-23.
    One of the main challenges confronting Humean accounts of natural law is that Humean laws appear to be unable to play the explanatory role of laws in scientific practice. The worry is roughly that if the laws are just regularities in the particular matters of fact (as the Humean would have it), then they cannot also explain the particular matters of fact, on pain of circularity. Loewer (2012) has defended Humeanism, arguing that this worry only arises if we fail to (...)

    Humeanism and Exceptions in the Fundamental Laws of Physics.Billy Wheeler - 2015 - Principia: An International Journal of Epistemology 21 (3):317-337.
    It has been argued that the fundamental laws of physics do not face a ‘problem of provisos’ equivalent to that found in other scientific disciplines (Earman, Roberts and Smith 2002) and there is only the appearance of exceptions to physical laws if they are confused with differential equations of evolution type (Smith 2002). In this paper I argue that even if this is true, fundamental laws in physics still pose a major challenge to standard Humean approaches to lawhood, as they (...)

    Making Best Systems Best for Us.Siegfried Jaag & Christian Loew - forthcoming - Synthese:1-26.
    Humean reductionism about laws of nature appears to leave a central aspect of scientific practice unmotivated: If the world’s fundamental structure is exhausted by the actual distribution of non-modal properties and the laws of nature are merely efficient summaries of this distribution, then why does science posit laws that cover a wide range of non-actual circumstances? In this paper, we develop a new version of the Humean best systems account of laws based on the idea that laws need to organize (...)

    The Limits of Humeanism.Jesse Mulder - 2018 - European Journal for Philosophy of Science 8 (3):671-687.
    Humeans take reality to be devoid of ‘necessary connections’: things just happen. Laws of nature are to be understood in terms of what ‘just happens’, not vice versa. Here the Humean needs some conception of what it is that ‘just happens’ – a conception of the Humean mosaic. Lewis’s Humeanism incorporates such a conception in the form of a Lewis-style metaphysics of objects, properties, and modality. Newer versions of Humeanism about laws of nature, such as the Better Best Systems approach, (...)

    This paper argues for a revised best system account of laws of nature. David Lewis's original BSA has two main elements. On the one hand, there is the Humean base, which is the totality of particular matters of fact that obtain in the history of the universe. On the other hand, there is what I call the ‘nomic formula’, which is a particular operation that gets applied to the Humean base in order to output the laws of nature. My revised (...)

    The Epistemology of Hedged Laws.Robert Kowalenko - 2011 - Studies in History and Philosophy of Science Part A 42 (3):445-452.
    Standard objections to the notion of a hedged, or ceteris paribus, law of nature usually boil down to the claim that such laws would be either 1) irredeemably vague, 2) untestable, 3) vacuous, 4) false, or a combination thereof. Using epidemiological studies in nutrition science as an example, I show that this is not true of the hedged law-like generalizations derived from data models used to interpret large and varied sets of empirical observations.

    This paper addresses a famous objection against David Lewis’s Best System Analysis (BSA) of laws of nature. The objection—anticipated and discussed by Lewis (1994)—focuses on the standards of simplicity and strength being (in part) a matter of psychology. Lewis’s answer to the objection relies on his metaphysics of natural properties and its ability to single out the robustly best system, a system that is expected to come out far ahead of its rivals under any standard of simplicity and strength.

    We critically analyse the point of view for which laws of nature are just a mean to compress data. Discussing some basic notions of dynamical systems and information theory, we show that the idea that the analysis of large amount of data by means of an algorithm of compression is equivalent to the knowledge one can have from scientific laws, is rather naive. In particular we discuss the subtle conceptual topic of the initial conditions of phenomena which are generally incompressible. (...)

    Leibniz on the Laws of Nature and the Best Deductive System.Joshua L. Watson - 2012 - Studies in History and Philosophy of Science Part A 43 (4):577-584.
    Many philosophers who do not analyze laws of nature as the axioms and theorems of the best deductive systems nevertheless believe that membership in those systems is evidence for being a law. This raises the question, “If the best systems analysis fails, what explains the fact that being a member of the best systems is evidence for being a law?” In this essay I answer this question on behalf of Leibniz. I argue that although Leibniz’s philosophy of laws is inconsistent (...)

The paper aims to show that two such thought experiments fail to establish that the Ramsey-Lewis view is false, since they presuppose a conception of laws of nature that is radically at odds with the Humean conception of laws embodied by the Ramsey-Lewis view. In particular, the thought experiments presuppose that laws of nature govern the behavior of objects. The paper (...)

    The better best system account, short BBSA, is a variation on Lewis’s theory of laws. The difference to the latter is that the BBSA suggests that best system analyses can be executed for any fixed set of properties. This affords the possibility to launch system analyses separately for the set of biological properties yielding the set of biological laws, chemical properties yielding chemical laws, and so on for the other special sciences. As such, the BBSA remains silent about possible interrelations (...)

    Orthodoxy has it that only metaphysically elite properties can be invoked in scientifically elite laws. We argue that this claim does not fit scientific practice. An examination of candidate scientifically elite laws like Newton’s F = ma reveals properties invoked that are irreversibly defined and thus metaphysically non-elite by the lights of the surrounding theory: Newtonian acceleration is irreversibly defined as the second derivative of position, and Newtonian resultant force is irreversibly defined as the sum of the component forces.

    Simplicity, Language-Dependency and the Best System Account of Laws.Billy Wheeler - 2014 - Theoria : An International Journal for Theory, History and Fundations of Science 31 (2):189-206.
    It is often said that the best system account of laws needs supplementing with a theory of perfectly natural properties. The ‘strength’ and ‘simplicity’ of a system is language-relative and without a fixed vocabulary it is impossible to compare rival systems. Recently a number of philosophers have attempted to reformulate the BSA in an effort to avoid commitment to natural properties. I assess these proposals and argue that they are problematic as they stand. Nonetheless, I agree with their aim, and (...)

We show that the challenge is not that dangerous, and that to account for it one need not invoke natural properties or relativized versions of the Best System account. This way, we help to move towards an even better Best System account. We discuss extensions of our (...)

While he seems to defend a Humean account of laws similar to Ramsey’s and Lewis’s, he also appears to rely on modal notions to distinguish lawful relations from accidental regularities. This paper will show that Mill’s two accounts of laws are in fact equivalent. This equivalence results from a proper understanding of the necessity involved in laws and a proper understanding of systematization. This equivalence reveals the true source of (...)

How, short of conspiracy, is this possible?

The circle is then cut because the kind of explanation the laws provide for the fundamental entities is distinct from the kind of explanation (...)

    Humean interpretations claim that laws of nature merely summarize events. Non-Humean interpretations claim that laws force events to occur in certain patterns. First, I show that the Lewis/Ramsey account of lawhood, which claims that laws are axioms or theorems of the simplest strongest summary of events, provides the best Humean interpretation of laws.

    The 'best-system' analysis of lawhood [Lewis 1994] faces the 'zero-fit problem': that many systems of laws say that the chance of history going actually as it goes--the degree to which the theory 'fits' the actual course of history--is zero. Neither an appeal to infinitesimal probabilities nor a patch using standard measure theory avoids the difficulty. But there is a way to avoid it: replace the notion of 'fit' with the notion of a world being typical with respect to a theory.
