  1. Ceteris Paribus Lost.John Earman, John T. Roberts & Sheldon Smith - 2002 - Erkenntnis 57 (3):281-301.
    Many have claimed that ceteris paribus laws are a quite legitimate feature of scientific theories, some even going so far as to claim that laws of all scientific theories currently on offer are merely CP. We argue here that one of the common props of such a thesis, that there are numerous examples of CP laws in physics, is false. Moreover, besides the absence of genuine examples from physics, we suggest that otherwise unproblematic claims are rendered untestable by the mere (...)

  2. "Ceteris Paribus", There Is No Problem of Provisos.John Earman & John T. Roberts - 1999 - Synthese 118 (3):439 - 478.
    Much of the literature on "ceteris paribus" laws is based on a misguided egalitarianism about the sciences. For example, it is commonly held that the special sciences are riddled with ceteris paribus laws; from this many commentators conclude that if the special sciences are not to be accorded a second class status, it must be ceteris paribus all the way down to fundamental physics. We argue that the (purported) laws of fundamental physics are not hedged by ceteris paribus clauses and (...)

    This is the first part of a two-part article in which we defend the thesis of Humean Supervenience about Laws of Nature (HS). According to this thesis, two possible worlds cannot differ on what is a law of nature unless they also differ on the Humean base. The Humean base is easy to characterize intuitively, but there is no consensus on how, precisely, it should be defined. Here in Part I, we present and motivate a characterization of the Humean base (...)

    In Part I, we presented and motivated a new formulation of Humean Supervenience about Laws of Nature (HS). Here in Part II, we present an epistemological argument in defense of HS, thus formulated. Our contention is that one can combine a modest realism about laws of nature with a proper recognition of the importance of empirical testability in the epistemology of science only if one accepts HS.

  6. A Puzzle About Laws, Symmetries and Measurability.John T. Roberts - 2008 - British Journal for the Philosophy of Science 59 (2):143-168.
    I describe a problem about the relations among symmetries, laws and measurable quantities. I explain why several ways of trying to solve it will not work, and I sketch a solution that might work. I discuss this problem in the context of Newtonian theories, but it also arises for many other physical theories. The problem is that there are two ways of defining the space-time symmetries of a physical theory: as its dynamical symmetries or as its empirical symmetries. The two (...)

  8. Fine-Tuning and the Infrared Bull’s-Eye.John T. Roberts - 2012 - Philosophical Studies 160 (2):287-303.
    I argue that the standard way of formalizing the fine-tuning argument for design is flawed, and I present an alternative formalization. On the alternative formalization, the existence of life is not treated as the evidence that confirms design; instead it is treated as part of the background knowledge, while the fact that fine tuning is required for life serves as the evidence. I argue that the alternative better captures the informal line of thought that gives the fine-tuning argument its intuitive (...)

  9. “Laws of Nature‘ as an Indexical Term: A Reinterpretation of Lewis’s Best-System Analysis.John T. Roberts - 1999 - Philosophy of Science 66 (3):511.
    David Lewis's best-system analysis of laws of nature is perhaps the best known sophisticated regularity theory of laws. Its strengths are widely recognized, even by some of its ablest critics. Yet it suffers from what appears to be a glaring weakness: It seems to grant an arbitrary privilege to the standards of our own scientific culture. I argue that by reformulating, or reinterpreting, Lewis's exposition of the best-system analysis, we arrive at a view that is free of this weakness. The (...)

  10. Leibniz on Force and Absolute Motion.John T. Roberts - 2003 - Philosophy of Science 70 (3):553-573.
    I elaborate and defend an interpretation of Leibniz on which he is committed to a stronger space-time structure than so-called Leibnizian space-time, with absolute speeds grounded in his concept of force rather than in substantival space and time. I argue that this interpretation is well-motivated by Leibniz's mature writings, that it renders his views on space, time, motion, and force consistent with his metaphysics, and that it makes better sense of his replies to Clarke than does the standard interpretation. Further, (...)

    CP-Law Statements as Vague, Self-Referential, Self-Locating, Statistical, and Perfectly in Order.John T. Roberts - 2014 - Erkenntnis 79 (S10):1775-1786.
    I propose understanding CP-law statements as statements that assert the existence of vague statistical laws, not by fully specifying the contents of those laws, but by picking them out via a description that is both self-referential and self-locating. I argue that this proposal validates many common assumptions about CP-laws and correctly classifies many examples of putative CP-laws. It does this while avoiding the most serious worries that motivate some philosophers to be skeptical of CP-laws, namely the worry that they lack (...)

    Undermining Undermined: Why Humean Supervenience Never Needed to Be Debugged (Even If It's a Necessary Truth).John T. Roberts - 2001 - Proceedings of the Philosophy of Science Association 2001 (3):S98-.
    The existence of "undermining futures" appears to show that a contradiction can be deduced from the conjunction of Humean supervenience (HS) about chance and the Principal Principle. A number of strategies for rescuing HS from this problem have been proposed recently. In this paper, a novel way of defending HS from the threat is presented, and it is argued that this defense has advantages not shared by others. In particular, it requires no revisionism about chance, and it is equally available (...)

  15. Some Laws of Nature Are Metaphysically Contingent.John T. Roberts - 2010 - Australasian Journal of Philosophy 88 (3):445-457.
    Laws of nature are puzzling because they have a 'modal character'—they seem to be 'necessary-ish'—even though they also seem to be metaphysically contingent. And it is hard to understand how contingent truths could have such a modal character. Scientific essentialism is a doctrine that seems to dissolve this puzzle, by showing that laws of nature are actually metaphysically necessary. I argue that even if the metaphysics of natural kinds and properties offered by scientific essentialism is correct, there are still some (...)

  17. Laws About Frequencies.John T. Roberts - unknown
    A law about frequencies would be a law of nature that imposes a constraint on one or more (actual, global) frequencies. On any of the leading philosophical approaches to laws of nature, there could be laws about frequencies. Hypotheses that posit laws about frequencies turn out to behave very similarly to hypotheses that posit corresponding laws about probabilities or chances -- they make the same predictions, provide similar explanations, and are confirmed or disconfirmed by empirical evidence in the same ways.

  18. Measurability And Physical Laws.John T. Roberts - 2005 - Synthese 144 (3):433-447.
    I propose and motivate a new account of fundamental physical laws, the Measurability Account of Laws (MAL). This account has a distinctive logical form, in that it takes the primary nomological concept to be that of a law relative to a given theory, and defines a law simpliciter as a law relative to some true theory. What makes a proposition a law relative to a theory is that it plays an indispensable role in demonstrating that some quantity posited by that (...)

  19. Chance Without Credence.John T. Roberts - 2013 - British Journal for the Philosophy of Science 64 (1):33-59.
    It is a standard view that the concept of chance is inextricably related to the technical concept of credence . One influential version of this view is that the chance role is specified by (something in the neighborhood of) David Lewis's Principal Principle, which asserts a certain definite relation between chance and credence. If this view is right, then one cannot coherently affirm that there are chance processes in the physical world while rejecting the theoretical framework in which credence is (...)

  22. The Semantic Novelty of Theoretical Terms.John T. Roberts - unknown
    Often when a new scientific theory is introduced, new terms are introduced along with it. Some of these new terms might be given explicit definitions using only terms that were in currency prior to the introduction of the theory. Some of them might be defined using other new terms introduced with the theory. But it frequently happens that the standard formulations of a theory do not define some of the new terms at all; these terms are adopted as primitives. The (...)

    Reply to Skow.John T. Roberts - 2007 - Philosophy and Phenomenological Research 75 (1):163-167.
    We have argued against a standard way of defining Humean supervenience about laws, and in favor of an alternative definition. Skow says that our argument against the standard definition makes a big mistake. He is right about this. But that mistake is correctable. Skow also argues that our alternative definition is seriously flawed. We think he is wrong about this.
