Prof. Darrell P. Rowbottom

Professor and Head, Department of Philosophy, Lingnan University

Honorary Professor, Department of Philosophy, University of Durham

Associate Editor, Australasian Journal of Philosophy


Prior to my appointment at Lingnan, I was a British Academy Postdoctoral Fellow at the Faculty of Philosophy, University of Oxford. I have also worked at several other universities in the UK, including Aberdeen, Bristol, Durham, and Edinburgh.

I started out studying physics, but undertook graduate studies in philosophy and history and philosophy of science. The shift of direction is easily explained: I was fascinated by quantum theory, and what my lecturers (wrongly!) thought that it tells us about the world.


I am interested in a wide variety of topics in philosophy of science, epistemology, metaphysics, and philosophy of probability. I also dabble in other areas, including philosophy of education and philosophy of mind, from time to time.

My main project at the moment is to complete a monograph in defence of a new form of instrumentalism about science. My work on this has been supported by a Humanities and Social Sciences Prestigious Fellowship from Hong Kong's Research Grant Council, and a COFUND Senior International Research Fellowship held at Durham University's Institute of Advanced Study.


Undergraduate Course Offerings 2015/2016

This year, I am giving a higher-level undergraduate course on 'Philosophy of Science'.

Recent Textbook

I have just completed a textbook on the philosophy of probability, which is imaginatively called 'Probability'. (In my defence, this was the title chosen by the publishers! It's part of a 'Key Concepts in Philosophy' series.) It's intended to be the most accessible introduction to the subject of how we should interpret, or understand, probabilities. It discusses real world applications, e.g. in fallacies and reasoning, quantum mechanics, genetics, and game theory.

(You can click on the image to go to the publisher's page for the book.)


'This is a remarkable book in that, while using the absolute minimum of mathematics, it manages to explain all the main views in the philosophy of probability clearly and accurately. Indeed it covers some recent approaches on which active research is taking place at the moment.'
Donald Gillies, University College London

'Easy and fun to read, this book is a thought-provoking introduction to a wide range of important theories and issues about the nature of probability.'
Timothy Williamson, University of Oxford


I am presently supervising four PhD students, each of whom holds a hotly-contested Hong Kong PhD Fellowship. These are:

Haktan Akcin, Christopher Atkinson, Alexander Ehmann, and Jenny Hung.

‘How Might Degrees of Belief Shift? On Actions Conflicting With Professed
Beliefs’, Philosophical Psychology (In Press)

People often act in ways that appear incompatible with their sincere assertions (such as trembling in fear when their death becomes an imminent possibility, despite earlier professing that “Death is not bad!”). But how might we explain such cases? On the shifting view, subjects’ degrees of belief (or degrees of confidence) may be highly sensitive to changes in context. This paper articulates and refines this view, after defending it against recent criticisms. It details two mechanisms by which degrees of beliefs may shift.

‘Extending the Argument from Unconceived Alternatives: Observations,
Models, Predictions, Explanations, Methods, Instruments, and Values’,
Synthese (In Press)

Stanford’s argument against scientific realism focuses on theories, just as many earlier arguments from inconceivability have. However, there are possible arguments against scientific realism involving unconceived (or inconceivable) entities of different types: observations, models, predictions, explanations, methods, instruments, experiments, and values. This paper charts such arguments. In combination, they present the strongest challenge yet to scientific realism.

‘Scientific Progress Without Increasing Verisimilitude: In Response to
Niiniluoto’, Studies in History and Philosophy of Science 51, 100–104 (2015)

First, I argue that scientific progress is possible in the absence of increasing verisimilitude in science’s theories. Second, I argue that increasing theoretical verisimilitude is not the central, or primary, dimension of scientific progress. Third, I defend my previous argument that unjustified changes in scientific belief may be progressive. Fourth, I illustrate how false beliefs can promote scientific progress in ways that cannot be explicated by appeal to verisimilitude.

‘Aimless Science’, Synthese 191(6), 1211–1221 (2014)

This paper argues that talk of ‘the aim of science’ should be avoided in the philosophy of science, with special reference to the way that van Fraassen sets up the difference between scientific realism and constructive empiricism. It also argues that talking instead of ‘what counts as success in science as such’ is unsatisfactory. The paper concludes by showing what this talk may be profitably replaced with, namely specific claims concerning science that fall into the following categories: descriptive, evaluative, normative, and definitional. There are two key advantages to this proposal. First, realism and its competitors may be understood to consist of highly nuanced variants. Second, scientific realism and its competitors may be understood as something other than ‘all or nothing’ theses about science. More particularly, one may accept that there are general claims concerning science in some of the identified categories, but deny that there are such claims in the others.

‘Information Versus Knowledge in Confirmation Theory’, Logique et Analyse 226, 137–149 (2014)

I argue that so-called 'background knowledge' in confirmation theory has little, if anything, to do with 'knowledge' in the sense of mainstream epistemology. I argue that it is better construed as 'background information', which need not be believed in, justified, or true.

‘Kuhn vs. Popper on Criticism and Dogmatism in Science, Part II: How to Strike the Balance’, Studies in History and Philosophy of Science 44(2), 161–168 (2013)

This paper is a supplement to, and provides a proof of principle of, Kuhn vs. Popper on Criticism and Dogmatism in Science: A Resolution at the Group Level. It illustrates how calculations may be performed in order to determine how the balance between different functions in science—such as imaginative, critical, and dogmatic—should be struck, with respect to confirmation (or corroboration) functions and rules of scientific method.

‘Group Level Interpretations of Probability: New Directions’, Pacific Philosophical Quarterly 94(2), 188–203 (2013)

In this paper, I present some new group level interpretations of probability, and champion one in particular: a consensus-based variant where group degrees of belief are construed as agreed upon betting quotients rather than shared personal degrees of belief. One notable feature of the account is that it allows us to treat consensus between experts on some matter as being on the union of their relevant background information. In the course of the discussion, I also introduce a novel distinction between intersubjective and interobjective interpretations of probability.

‘Empirical Evidence Claims Are A Priori’, Synthese 190(14), 2821–2834 (2013)

This paper responds to Achinstein’s criticism of the thesis that the onlyempirical fact that can affect the truth of an objective evidence claim such as ‘e is evidence for h’ (or ‘e confirms h to degree r’) is the truth of e. It shows that cases involving evidential flaws, which form the basis for Achinstein’s objections to the thesis, can satisfactorily be accounted for by appeal to changes in background information and working assumptions. The paper also argues that the a priori and empirical accounts of evidence are on a par when we consider scientific practice, but that a study of artificial intelligence might serve to differentiate them.

‘Popper's Measure of Corroboration and P(h,b)’, British Journal for the
Philosophy of Science
64(4), 739–745 (2013)

This paper shows that Popper's measure of corroboration is inapplicable if, as Popper also argued, the logical probability of synthetic universal statements is zero relative to any evidence that we might possess. It goes on to show that Popper's definition of degree of testability, in terms of degree of logical content, suffers from a similar problem.

‘Bertrand's Paradox Revisited: Why Bertrand's “Solutions” Are All Inapplicable’, Philosophia Mathematica 21, 110–114 (2013)

This paper shows that Bertrand's proposed 'solutions' to his own question, which generates his chord paradox, are inapplicable. It uses a simple analogy with cake cutting. The problem is that none of Bertrand's solutions considers all possible cuts. This is no solace for the defenders of the principle of indifference, however, because it emerges that the paradox is harder to solve than previously anticipated.

‘Identification in Games: Changing Places’, Erkenntnis 77, 197–206 (2012)

This paper offers a novel 'changing places' account of identification in games, where the consequences of role swapping are crucial. First, it illustrates how such an account is consistent with the view, in classical game theory, that only outcomes (and not pathways) are significant. Second, it argues that this account is superior to the 'pooled resources' alternative when it comes to dealing with some situations in which many players identify. Third, it shows how such a 'changing places' account can be used in games where some of the players identify with one another, but others do not. Finally, it illustrates how the model can handle the notion that identification comes in degrees.

‘The Role of Hypotheses in Biomechanical Research’ (with Neill Alexander),
Science in Context 25, 247–262 (2012)

This paper investigates whether there is a discrepancy between the stated and actual aims in biomechanical research, particularly with respect to hypothesis testing. We present an analysis of one hundred papers recently published in The Journal of Experimental Biology and Journal of Biomechanics, and examine the prevalence of papers which (a) have hypothesis testing as a stated aim, (b) contain hypothesis testing claims that appear to be purely presentational (i.e. which seem not to have influenced the actual study), and (c) have exploration as a stated aim. We found that whereas no papers had exploration as a stated aim, 58% of papers had hypothesis testing as a stated aim. We had strong suspicions, at the bare minimum, that presentational hypotheses were present in 31% of the papers in this latter group.

‘The Instrumentalist’s New Clothes’, Philosophy of Science 78, 1200–1211 (2011)

This paper develops a new version of instrumentalism, in light of progress in the realism debate in recent decades, and thereby defends the view that instrumentalism remains a viable philosophical position on science. The key idea is that talk of unobservable objects should be taken literally only when those objects are assigned properties (or described in terms of analogies involving things) with which we are experientially (or otherwise) acquainted. This is derivative from the instrumentalist tradition in so far as the distinction between unobservable and observable is taken to have significance with respect to meaning.

Popper's Critical Rationalism: A Philosophical Investigation (London: Routledge, 2011)


Popper’s Critical Rationalism presents Popper’s views on science, knowledge, and inquiry, and examines the significance and tenability of these in light of recent developments in philosophy of science, philosophy of probability, and epistemology. It develops a fresh and novel philosophical position on science, which employs key insights from Popper while rejecting other elements of his philosophy.

‘Kuhn vs. Popper on Criticism and Dogmatism in Science: A Resolution at the
Group Level’, Studies in History and Philosophy of Science 42(1), 117–124

Popper repeatedly emphasised the significance of a critical attitude, and a related critical method, for scientists. Kuhn, however, thought that unquestioning adherence to the theories of the day is proper; at least for ‘normal scientists’. In short, the former thought that dominant theories should be attacked, whereas the latter thought that they should be developed and defended (for the vast majority of the time).

Both seem to have missed a trick, however, due to their apparent insistence that each individual scientist should fulfil similar functions (at any given point in time). The trick is to consider science at the group level; and doing so shows how puzzle solving and ‘offensive’ critical activity can simultaneously have a legitimate place in science. This analysis shifts the focus of the debate. The crucial question becomes ‘How should the balance between functions be struck?’

‘Approximations, Idealizations and “Experiments” at the Physics-Biology
Interface’, Studies in History and Philosophy of Biological and Biomedical
42(2), 145–154 (2011)

This paper, which is based on recent empirical research at the University of Leeds, the University of Edinburgh, and the University of Bristol, presents two difficulties which arise when condensed matter physicists interact with molecular biologists: (1) the former use models which appear to be too coarse-grained, approximate and/or idealized to serve a useful scientific purpose to the latter; and (2) the latter have a rather narrower view of what counts as an experiment, particularly when it comes to computer simulations, than the former. It argues that these findings are related; that computer simulations are considered to be undeserving of experimental status, by molecular biologists, precisely because of the idealizations and approximations that they involve. The complexity of biological systems is a key factor. The paper concludes by critically examining whether the new research programme of ‘systems biology’ offers a genuine alternative to the modelling strategies used by physicists. It argues that it does not.

‘Stances and Paradigms: A Reflection’, Synthese 178(1), 111–119 (2011)

This paper compares and contrasts the concept of a stance with that of a paradigm qua disciplinary matrix, in an attempt to illuminate both notions. First, it considers to what extent it is appropriate to draw an analogy between stances (which operate at the level of the individual) and disciplinary matrices (which operate at the level of the community). It suggests that despite first appearances, a disciplinary matrix is not simply a stance writ large. Second, it examines how we might reinterpret disciplinary matrices in terms of stances, and shows how doing so can provide us with a better insight into non-revolutionary science. Finally, it identifies two directions for future research: “Can the rationality of scientific revolutions be understood in terms of the dynamic between stances and paradigms?” and “Do stances help us to understand incommensurability between disciplinary matrices?”

In this essay review, I argue that that there is a problem with the way that scientific realists tend to motivate belief in the metaphysical underpinnings of their position, or the so-called ‘metaphysical thesis of scientific realism’. I use Sankey’s approach as an illustration of the epistemological problems, in particular, with the inappropriate uses of presupposition and appeals to ‘common sense’.

‘The Use and Misuse of Taxpayers’ Money: Publicly-Funded Educational
Research’ (with Sarah Aiston), British Educational Research Journal 37(4),
631–655 (2011)

How should educational research be contracted? And is there anything wrong with the way that public funding of educational research is currently administered? We endeavour to answer these questions by appeal to the work of two of the most prominent philosophers of science of the twentieth century, namely Popper and Kuhn. Although their normative views of science are radically different, we show that they would nonetheless agree on a number of key rules concerning the extent to which scientific practice should be influenced ‘from the outside’. We then show that these rules are often broken in the way that research is publicly funded in the UK.

‘How to Change It: Modes of Engagement, Rationality, and Stance
Voluntarism’ (with Otávio Bueno), Synthese 178(1), 7–17 (2011)

We have three goals in this paper. First, we outline an ontology of stance, and explain the role that modes of engagement and styles of reasoning play in the characterization of a stance. Second, we argue that we do enjoy a degree of control over the modes of engagement and styles of reasoning we adopt. Third, we contend that maximizing one’s prospects for change (within the framework of other constraints, e.g., beliefs, one has) also maximizes one’s rationality.

‘Evolutionary Epistemology and the Aim of Science’, Australasian Journal of
88(2), 209–225 (2010)

Both Popper and van Fraassen have used evolutionary analogies to defend their views on the aim of science, although these are diametrically opposed. By employing Price's equation in an illustrative capacity, this paper considers which view is better supported. It shows that even if our observations and experimental results are reliable, an evolutionary analogy fails to demonstrate why conjecture and refutation should result in: (1) the isolation of true theories; (2) successive generations of theories of increasing truth-likeness; (3) empirically adequate theories; or (4) successive generations of theories of increasing proximity to empirical adequacy. Furthermore, it illustrates that appeals to induction do not appear to help. It concludes that an evolutionary analogy is only sufficient to defend the notion that the aim of science is to isolate a particular class of false theories, namely those that are empirically inadequate.

It argues that a corroboration-based account is equal to the popular Bayesian alternative, which has received much more recent attention, in this respect.
