    This is a collection of nineteen essays in the tradition of critical rationalism (as advocated by Karl Popper). All but one of the essays is previously unpublished and the one previously published paper has undergone significant revisions. The first four essays tackle topics in the philosophy of science, the first being an exposition of Popper's views, the others discussing falsifiability, truth, the aim of science, and ceteris-paribus law-statements. Five essays follow concerned with Reason, re…Read more

    Are Institutions Created by Collective Acceptance?
    Journal of Value Inquiry 54 (3): 443-455. 2020.
    John Searle, in several articles and books, has contended that institutions incorporating status functions with deontic powers are created by collective acceptance. I argue that collective acceptance can create new status functions with deontic powers only if other status functions with deontic powers already exist, so that collective acceptance can create new institutions only if other institutions are presupposed. So, the claim that institutions depend upon collective acceptance involves a vic…Read more

    I consider cases in which risk or ignorance create barriers to our discovery of what we ought to do. I argue that neither expected utility theory, nor the maximin principle, nor a timid gambling temperament, is relevant to discovering what we ought to do in one-off or infrequently recurring types of decisions involving risk, or to decisions involving ignorance. I argue, contra Kolodny and MacFarlane, that the miners case does not require us to give up any classical logical principle in order to …Read more

    John Schwenkler asks whether we should shield ourselves from others' abhorrent beliefs. I expound and criticise his discussion and I explain why a rational person who wants to improve his knowledge should not shield himself from abhorrent beliefs.

    Susan Haack criticises the US courts' use of Karl Popper's epistemology in discriminating acceptable scientific testimony. She claims that acceptable testimony should be reliable and that Popper's epistemology is useless in discriminating reliability. She says that Popper's views have been found acceptable only because they have been misunderstood and she indicates an alternative epistemology which she says can discriminate reliable theories. However, her account of Popper's views is a gross and…Read more

    In ‘Aeon’ magazine (2 August 2017), Professor Paul Russell claims that tolerance demands that criticism of ideologies be permitted; but it also demands that criticism of natural identities be suppressed. He says that the Left’s failure to distinguish ideological from non-ideological identities has led identity politics into intolerance. I argue that Russell’s position is self-contradictory, implying that his (ideological) liberal identity both should and should not be open to criticism. Toleranc…Read more

    Falsificationism and the Pragmatic Problem of Induction
    Organon F: Medzinárodný Časopis Pre Analytickú Filozofiu 27 (4): 494-503. 2020.
    I explain how Karl Popper resolved the problem of induction but not the pragmatic problem of induction. I show that Popper’s solution to the pragmatic problem of induction is inconsistent with his solution to the problem of induction. I explain how Popper’s falsificationist epistemology can solve the pragmatic problem of induction in the same negative way that it solves the problem of induction.

    Book Review: Mark Simpson (ed.) 'Anti-Gay' (review)
    Free Life 27 26-27. 1997.
    The theme of this book is that the gay community has stereotyped itself and has imposed a conformity upon its members that stifles their development and forces them to suppress aspects of themselves that do not fit the approved model of the gay lifestyle. The review focuses on, and criticises, Peter Tatchell's contribution.

    Freedom, Indeterminism, and Fallibilism
    Palgrave Macmillan. 2020.
    This book uses the concepts of freedom, indeterminism, and fallibilism to solve, in a unified way, problems of free will, knowledge, reasoning, rationality, personhood, ethics and politics. Presenting an overarching theory of human freedom, Frederick argues for an account of free will as the capacity for undetermined acts. Knowledge, rationality, and reasoning, both theoretical and practical, as well as personhood, morality and political authority, are all shown to be dependent at their roots on…Read more

    Dummett defines a ‘predicate’ as that which combines with one or more singular terms to form a sentence. His account of ‘singular term’ is syntactical, involving three necessary conditions. He discusses a fourth, ‘Aristotelian’, criterion before propounding a criterion of predicate quantification which he claims to be superior to it. He tentatively proposes that the three necessary conditions plus the criterion of predicate quantification yield sufficient conditions for being a singular term. I …Read more

    Winning the Argument?
    In Against the Philosophical Tide, Critias Publishing. pp. 195-197. 2020.
    Theft is win-lose: the thief gains benefits at the expense of the victim. War is lose-lose: no-one comes out better off. Trade is win-win: both parties gain. Altercations are lose-lose. When a person talks about ‘winning the argument,’ she is talking about winning a debate and she sees debate as win-lose. But if we partake of debates with an open mind, they can be win-win: even without agreeing, each party may learn. Unfortunately, contemporary philosophers seem to see debate as win-lose in whic…Read more

    I criticise, from a critical rationalist perspective, Israel Kirzner's notion of entrepreneurial alertness and Matthew McCaffrey's endorsement of Joseph Salerno's rival account of entrepreneurial judgment.

    It is an article of almost religious faith in the United Kingdom that the National Health Service is far superior to a competitive market in health care services. In this brief and informal paper I show that the opposite is true. In contrast to market provision, the existence of the National Health Service entails the following. First, consumer sovereignty is virtually destroyed, since what services the consumer receives and how much he pays (through taxation) are determined by the government of…Read more

    Criticisms of Karl Popper’s critical rationalist epistemology are often confused and misleading. In part that is due to Popper’s somewhat lax use of language, in which technical terms are used in more than one sense. I attempt to clarify Popper’s views by regimenting his terminology. The result is offered as a clear and concise exposition of the main points of Popper’s epistemology. This is an updated version of a paper that was published in Cosmos + Taxis 6 (6+7): 49-54 (2019).

    A central problem of political philosophy is that of explaining how a state could have the moral authority to enforce laws, promulgate laws which citizens are thereby obliged to obey, give new duties to citizens and levy taxes. Many rival solutions to this problem of political authority have been offered by contemporary and recent philosophers but none has obtained wide acceptance. The current debate takes no cognisance of George Berkeley’s ‘Passive Obedience’, in which he defends the exceptionl…Read more

    Book Review: 'An Essay on Rights,' Hillel Steiner (review)
    Free Life 24 26-27. 1995.
    Hillel Steiner’s argument in this book is bold, imaginative and illuminating, despite being vitiated by some logical errors and a wholly impractical redistributive method.

    Reply to Mark Friedman
    Reason Papers 37 (1): 85-87. 2015.
    I reply to Mark Friedman's response to my review of his book, 'Nozick's Libertarian Project.' I restate what I take to be the key mistakes in Friedman’s arguments for individual rights and the minimal state. I outline the explanation of the right to freedom in terms of the human capacity for critical rationality, and the explanation of the poliitcial authority of the state in rule-consequentialist terms which do not appeal to consent.

    This book tells part of the story of my life in a succession of anecdotes, or ‘Danecdotes,’ as a friend called them. It generally focuses on the unusual and thereby offers material for reflection. I often include some more or less philosophical reflections within the anecdotes; and such reflections often raise further questions too. The book may be considered as a contribution to ‘the philosophy of everyday life.’ The anecdotes are autobiographical and are presented in approximately chronologica…Read more

    The authors of the papers in A Simple Matter of Justice? reject something they label “heterosexism.” Their writing is obscure, but it seems they desire a state-regimented conformity, with state-approved roles for gays, for lesbians and for others, with state hand-outs and other privileges for all manner of favoured groups, and with no possibility of anyone indulging in the pleasures of “commercial consumerism.” None of the authors appears concerned with the demand that, provided he/she does not …Read more

    The UK School Curriculum and Assessment Authority proposes a set of values to which everyone can subscribe, which can provide schools with a secure basis for the provision of spiritual, moral, social and cultural education. The proposal is misguided. The code would be determined by political negotiation, which would bring the whole idea of moral education into disrepute, and it would be an impediment to moral advancement, which requires trial and error experimentation. Imposing a code on all sta…Read more
  • In many of his publications, Karl Popper was highly critical of essentialism. In recent decades there has been a revival of essentialism in philosophy. However, modern essentialism, unlike its traditional version, is not undermined by Popper’s arguments against essentialism. To some extent Popper recognised that, in that he proposed an essentialist theory
  • I explain what haecceities are and the role they play in our thought and talk about specific individual things, whether those things are concrete or abstract. Everything that can be referred to by using a singular term has a haecceity. I distinguish between singular terms and general terms, on the one hand, and subject terms and predicate terms, on the other. I distinguish three types of sentence: singular predications; general predications; and singular quantifications. I show how singular pred…Read more
