    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

    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.

    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

    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

    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

    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

    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.

    ‘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.

    Why universal welfare rights are impossible and what it means
    Politics, Philosophy and Economics 9 (4): 428-445. 2010.
    Cranston argued that scarcity makes universal welfare rights impossible. After showing that this argument cannot be avoided by denying scarcity, I consider four challenges to the argument which accept the possibility of conflicts between the duties implied by rights. The first denies the agglomeration principle; the second embraces conflicts of duties; the third affirms the violability of all rights-based duties; and the fourth denies that duties to compensate are overriding. I argue that all fo…Read more

    A Critique of Lester's Account of Liberty
    Libertarian Papers 5 45-66. 2013.
    In Escape from Leviathan, Jan Lester sets out a conception of liberty as absence of imposed cost which, he says, advances no moral claim and does not premise an assignm..

    Pro-tanto Obligations and Ceteris-paribus Rules
    Journal of Moral Philosophy 12 (3): 255-266. 2015.
    I summarize a conception of morality as containing a set of rules which hold ceteris paribus and which impose pro-tanto obligations. I explain two ways in which moral rules are ceteris-paribus, according to whether an exception is duty-voiding or duty-overriding. I defend the claim that moral rules are ceteris-paribus against two qualms suggested by Luke Robinson’s discussion of moral rules and against the worry that such rules are uninformative. I show that Robinson’s argument that moral rules …Read more

    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: Robert Audi, 'Moral Perception' (review)
    Reason Papers 37 (1): 164-69. 2015.
    I summarise Robert Audi's 'Moral Perception.' I concede that there is such a thing as moral perception. However, moral perceptions are culturally-relative, which refutes Audi’s claims that moral perception may ground moral knowledge and that it provides inter-subjectively accessible grounds which make ethical objectivity possible. Audi's attempt to avoid the refutation tends to convert rational disputes into ad hominem ones. I illustrate that with the example of the ethics of prostitution.

    Pro‐Tanto versus Absolute Rights
    Philosophical Forum 45 (4): 375-394. 2014.
    Judith Jarvis Thomson and others contend that rights are pro-tanto rather than absolute, that is, that rights may permissibly be infringed in some circumstances. Alan Gewirth maintains that there are some rights that are absolute because infringing them would amount to unspeakable evil. However, there seem to be possible circumstances in which it would be permissible to infringe even those rights. Specificationists, such as Gerald Gaus, Russ Shafer-Landau, Hillel Steiner and Kit Wellman, argue t…Read more

    Freedom: Positive, Negative, Expressive
    Reason Papers 38 (2): 39-63. 2016.
    I apply Karl Popper’s conception of critical rationality to the question of personal fulfilment. I show that such fulfilment normally depends upon the person achieving positive freedom, and that positive freedom requires negative freedom, including freedom of expression. If the state has legitimacy, its central duty must be the enforcement of those rules that provide the best prospects for personal fulfilment for the people under its jurisdiction. The state is therefore morally debarred from sup…Read more

    It is often contended that the special sciences, and even fundamental physics, make use of ceteris-paribus law-statements. Yet there are general concerns that such law-statements are vacuous or untestable or unscientific. I consider two main kinds of ceteris-paribus law-statement. I argue that neither kind is vacuous, that one of the kinds is untestable, that both kinds may count as scientific to the extent that they form parts of conjunctions that imply novel falsifiable statements which surviv…Read more

    The Possibility of Contractual Slavery
    Philosophical Quarterly 66 (262): 47-64. 2016.
    In contrast to eminent historical philosophers, almost all contemporary philosophers maintain that slavery is impermissible. In the enthusiasm of the Enlightenment, a number of arguments gained currency which were intended to show that contractual slavery is not merely impermissible but impossible. Those arguments are influential today in moral, legal and political philosophy, even in discussions that go beyond the issue of contractual slavery. I explain what slavery is, giving historical and ot…Read more

    Free will and probability
    Canadian Journal of Philosophy 43 (1): 60-77. 2013.
    The chance objection to incompatibilist accounts of free action maintains that undetermined actions are not under the agent's control. Some attempts to circumvent this objection locate chance in events posterior to the action. Indeterministic-causation theories locate chance in events prior to the action. However, neither type of response gives an account of free action which avoids the chance objection. Chance must be located at the act of will if actions are to be both undetermined and under t…Read more

    The Contrast Between Dogmatic and Critical Arguments
    Organon F: Medzinárodný Časopis Pre Analytickú Filozofiu 22 (1): 9-20. 2015.
    Karl Popper lamented the prevalence of dogmatic argument in philosophy and commended the kind of critical argument that is found in the sciences. David Miller criticises the uncritical nature of so-called critical thinking because of its attachment to dogmatic arguments. I expound and clarify Popper’s distinction between critical and dogmatic arguments and the background to it. I criticise some errors in Miller’s discussion. I reaffirm the need for philosophers to eschew dogmatic arguments in fa…Read more

    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.

    Pornography and Freedom
    Kritike 5 (2): 84-95. 2011.
    I defend pornography as an important aspect of freedom of expression, which is essential for autonomy, self-development, the growth of knowledge and human flourishing. I rebut the allegations that pornography depraves and corrupts, degrades women, is harmful to children, exposes third parties to risk of offence or assault, and violates women ’s civil rights and liberties. I contend that suppressing pornography would have a range of unintended evil consequences, including loss of beneficial techn…Read more

    Doxastic Voluntarism: A Sceptical Defence
    International Journal for the Study of Skepticism 3 (1): 24-44. 2013.
    Doxastic voluntarism maintains that we have voluntary control over our beliefs. It is generally denied by contemporary philosophers. I argue that doxastic voluntarism is true: normally, and insofar as we are rational, we are able to suspend belief and, provided we have a natural inclination to believe, we are able to rescind that suspension, and thus to choose to believe. I show that the arguments that have been offered against doxastic voluntarism fail; and that, if the denial of doxastic volun…Read more

    In Chapter 2 of Escape from Leviathan, Jan Lester defends two hypotheses: that instrumental rationality requires agents to maximise the satisfaction of their wants and that all agents actually meet this requirement. In addition, he argues that all agents are self-interested (though not necessarily egoistic) and he offers an account of categorical moral desires which entails that no agent ever does what he genuinely feels to be morally wrong. I show that Lester’s two hypotheses are false because …Read more
