    Hans-Hermann Hoppe contends that the fact that a person has the capacity to argue entails that she has the moral right of exclusive control over her own body. Critics of Hoppe’s argument do not appear to have pinpointed its flaws. I expose the logical structure of Hoppe’s argument, distinguishing its pragmatic-contradiction and its mutual-recognition components. I provide three counterexamples to show that Hoppe’s mutual-recognition argument is invalid and I argue that the truth that appears to …Read more

    Popper and Free Will
    Studia Philosophica Estonica 3 (1): 21-38. 2010.
    Determinism seems incompatible with free will. However, even indeterminism seems incompatible with free will, since it seems to make free actions random. Popper contends that free agents are not bound by physical laws, even indeterministic ones, and that undetermined actions are not random if they are influenced by abstract entities. I argue that Popper could strengthen his account by drawing upon his theories of propensities and of limited rationality; but that even then his account would not f…Read more

    A Competitive Market in Human Organs
    Libertarian Papers 2 1-21. 2010.
    I offer consequentialist and deontological arguments for a competitive market in human organs, from live as well as dead donors. I consider the objections that a market in organs will frustrate altruism, coerce the desperate, expose under-informed agents to unacceptable risks, exacerbate inequality, degrade those who participate in it, involve a kind of slavery, impose invidious costs, and impair third-party choice sets. I show that each of these objections is without merit and that, in conseque…Read more

    Ethical Intuitionism: A Structural Critique
    Journal of Value Inquiry 50 (3): 631-47. 2016.
    Ethical intuitionists regard moral knowledge as deriving from moral intuition, moral observation, moral emotion and inference. However, moral intuitions, observations and emotions are cultural artefacts which often differ starkly between cultures. Intuitionists attribute uncongenial moral intuitions, observations or emotions to bias or to intellectual or moral failings; but that leads to sectarian ad hominen attacks. Intuitionists try to avoid that by restricting epistemically genuine intuitions…Read more

    A puzzle about natural laws and the existence of God
    International Journal for Philosophy of Religion 73 (3): 269-283. 2013.
    The existence of natural laws, whether deterministic or indeterministic, and whether exceptionless or ceteris paribus, seems puzzling because it implies that mindless bits of matter behave in a consistent and co-ordinated way. I explain this puzzle by showing that a number of attempted solutions fail. The puzzle could be resolved if it were assumed that natural laws are a manifestation of God’s activity. This argument from natural law to God’s existence differs from its traditional counterparts …Read more

    Unmotivated Intentional Action
    Philosophical Frontiers 5 (1): 21-30. 2010.
    In opposition to the tenet of contemporary action theory that an intentional action must be done for a reason, I argue that some intentional actions are unmotivated. I provide examples of arbitrary and habitual actions that are done for no reason at all. I consider and rebut an objection to the examples of unmotivated habitual action. I explain how my contention differs from recent challenges to the tenet by Hursthouse, Stocker and Pollard.

    Scarcity and Saving Lives
    The Reasoner 5 (6): 89-90. 2011.
    I argue that, because of scarcity, the right to life cannot imply an obligation on others to save the life of the right-holder, and that collectivising resources for health care not only ensures that resources are used inefficiently and inappropriately but also removes from people the authority to make decisions for themselves about matters of health, life and death.

    To Follow the Argument Wherever It Leads
    The Reasoner 3 (11): 5-6. 2009.
    This paper rejects the claim that, rationally, we should follow the argument wherever it leads.

    Defective Equilibrium
    Organon F: Medzinárodný Časopis Pre Analytickú Filozofiu 23 (4): 443-59. 2016.
    I argue that the conception of reflective equilibrium that is generally accepted in contemporary philosophy is defective and should be replaced with a conception of fruitful reflective disequilibrium which prohibits ad hoc manoeuvres, encourages new approaches, and eschews all justification in favour of continuous improvement. I suggest how the conception of fruitful disequilibrium can be applied more effectively to moral enquiry, to encourage genuine progress in moral knowledge, if we make mora…Read more

    Moral Laws, Laws of Nature and Dispositions
    Prolegomena: Journal of Philosophy 13 (2): 303-14. 2014.
    It appears that light may be thrown on the nature of moral principles if they are construed as moral laws analogous to ceteris-paribus laws of nature. Luke Robinson objects that the analogy either cannot explain how moral principles are necessary or cannot explain how obligations can be pro-tanto; and that a dispositional account of moral obligation has explanatory superiority over one in terms of moral laws. I explain the analogy, construing laws of nature as necessary relationships after the f…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

    Deduction and Novelty
    The Reasoner 5 (4): 56-57. 2011.
    It is often claimed that the conclusion of a deductively valid argument is contained in its premises. Popper refuted this claim when he showed that an empirical theory can be expected always to have logical consequences that transcend the current understanding of the theory. This implies that no formalisation of an empirical theory will enable the derivation of all its logical consequences. I call this result ‘Popper-incompleteness.’ This result appears to be consistent with the view of deductiv…Read more

    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

    Two Concepts Of Rationality
    Libertarian Papers 2 1-21. 2010.
    The dominant tradition in Western philosophy sees rationality as dictating. Thus rationality may require that we believe the best explanation and simple conceptual truths and that we infer in accordance with evident rules of inference. I argue that, given what we know about the growth of knowledge, this authoritarian concept of rationality leads to absurdities and should be abandoned. I then outline a libertarian concept of rationality, derived from Popper, which eschews the dictates and which s…Read more

    P. F. Strawson on Predication
    Polish Journal of Philosophy 5 (1): 39-57. 2011.
    Strawson offers three accounts of singular predication: a grammatical, a category and a mediating account. I argue that the grammatical and mediating accounts are refuted by a host of counter-examples and that the latter is worse than useless. In later works Strawson defends only the category account. This account entails that singular terms cannot be predicates; it excludes non-denoting singular terms from being logical subjects, except by means of an ad hoc analogy; it depends upon a notion of…Read more

    A very brief outline of Popper's methodology.
  •  51
    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

    Confusion about the Right to Life
    The Reasoner 5 (1): 4-5. 2011.
    I defend the consistency of affirming the right to life while rejecting universal healthcare and liveable income programmes. I also defend the rationality of accepting inconsistency.

    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

    Social Contract Theory Should Be Abandoned
    Rationality, Markets and Morals 4 178-89. 2013.
    I argue that social-contract theory cannot succeed because reasonable people may always disagree, and that social-contract theory is irrelevant to the problem of the legitimacy of a form of government or of a system of moral rules. I note the weakness of the appeal to implicit agreement, the conflation of legitimacy with stability, the undesirability of “public justification” and the apparent blindness to the evolutionary critical-rationalist approach of Hayek and Popper. I employ that approach …Read more

    If the task of theoretical reason is to discover truth, or reasons for belief, then theoretical reason is impossible. Attempts to circumvent that by appeal to probabilities are self-defeating. If the task of practical reason is to discover what we ought to do or what actions are desirable or valuable, then practical reason is impossible. Appeals to the subjective ought or to subjective probabilities are self-defeating. Adapting Karl Popper, I argue that the task of theoretical reason is to obtai…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

    ‘Objectification’ and Obfuscation
    Kritike 10 (2): 173-90. 2016.
    Martha Nussbaum attempts to improve the clarity of the obscure talk of feminists and conservatives about objectification in connection with sexual matters. Her discussion is a substantial improvement. However, it is inconsistent and opaque, and she continues to apply the pejorative term ‘objectification’ to activities which she herself admits are morally unproblematic and which may even be a joyous part of life. I explain the deficiencies in Nussbaum’s discussion, including the fact that she doe…Read more

    Deduction and Novelty Again
    The Reasoner 8 (5): 51-52. 2014.
    It is commonly claimed that the conclusion of a valid deductive argument is contained in its premises and says nothing new. In 'Deduction and Novelty,' in The Reasoner 5 (4), pp. 56-57, I refuted that claim. In The Reasoner, 8 (3), pp. 24-25, David McBride criticised my refutation. I show that McBride’s arguments are unsound.
