If the task of theoretical reason is to discover truth or reasons for belief, then theoretical reason is impossible. Attempts to circumvent this 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. Appeal to the subjective ought is self-defeating and often gives either a wrong answer or a self-contradictory one. I argue that the task of theoretical reason (...) is to decide which propositions to instate; and that the task of practical reason is to decide which ought-propositions to act on. As a consequence theoretical reason is seen as a branch of practical reason. This approach makes both theoretical and practical reason practicable and free of the defects of the usual accounts.

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 in that, whereas the latter (...) seek to explain the fact of natural laws, the former seeks to explain their possibility . The customary objections to the traditional arguments cannot be successfully adapted to counter this new argument, with one exception which has only limited effect. I rebut four claims that the theistic solution to the puzzle about natural laws is paradoxical, though I concede that one of these claims has merit. I consider four objections to the new argument but find three of them more or less unsatisfactory. The fourth, if successful, would undermine our claims to know the truth about the world. (shrink)

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 the agent’s control. This (...) dissolves the apparent paradox of Frankfurt-type cases as well as the chance objection to incompatibilist free will. (shrink)

I summarise 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 cannot ground pro-tanto obligations (...) is unsound, because it confuses an absolute reason for an obligation with a reason for an absolute obligation, and because it overlooks the possibility that priority rules may be rules for ordering pro-tanto obligations rather than rules for eliminating contenders for the status of absolute obligation.

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..

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 voluntarism (...) is part of a strategy to defeat scepticism, it is inept, because knowledge presupposes doubt.

Social science employs teleological explanations which depend upon the rationality principle, according to which people exhibit instrumental rationality. Popper points out that people also exhibit critical rationality, the tendency to stand back from, and to question or criticise, their views. I explain how our critical rationality impugns the explanatory value of the rationality principle and thereby threatens the very possibility of social science. I discuss the relationship between instrumental and critical rationality and show how we can reconcile our critical rationality (...) with the possibility of social science if we invoke Popper’s conception of limited rationality and his indeterminism.

Schueler has argued, against the eliminativist, that human purposive action cannot be an illusion because the concept of purpose is not theoretical. He argues that the concept is known directly to be instantiated, through self-awareness; and that to maintain that the concept is theoretical involves an infinite regress. I show that Schueler’s argument fails because all our concepts are theoretical in the sense that we may be mistaken in applying them to our experience. As a consequence, it is conceivable that (...) direct introspection of an event as a purposive action may be mistaken. I indicate ways in which the eliminativist may be able to explain why our perception and introspection is afflicted with systematic error. (shrink)

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.

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 deductive reasoning as a (...) process of unfurling the content of the premises; but I suggest that the result about validity impugns this theory of reasoning.

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 technology, creeping censorship, black markets, corruption and extensive social (...) costs.

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 identification that (...) is too vague; and it is unnecessarily complicated, relying on analogies where a more uniform explanation should be possible. But I show how the account can be corrected to avoid all these difficulties and to provide an accurate account of singular predication. (shrink)

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.

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 consequence, the opposition to markets in (...) organs is an untenable endorsement of death, suffering and the suppression of freedom.

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 fully explain why free (...) actions are not random. I offer a solution to this problem which draws on Hornsby’s analysis of action. I then borrow an idea of Kant about self-consciousness to distinguish free agents from sub-human animals. I make a brief evaluation of Popper’s contribution. (shrink)

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 sees a rational agent as (...) one who questions, criticises, conjectures and experiments. I argue that, while the libertarian approach escapes the absurdities of the authoritarian, it requires two significant developments and an important clarification to be made fully consistent with itself.

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.

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 four challenges to the scarcity argument are (...) unsuccessful. I then discuss Eddy’s recent challenge, which makes welfare rights context dependent, but I argue that this also fails because it makes rights unknowable. I conclude that the scarcity argument, restated in the light of the discussion, shows that universal welfare rights, as ordinarily understood, are impossible and I explain the philosophical and practical significance of this conclusion.

This paper rejects the claim that, rationally, we should follow the argument wherever it leads.

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 they cannot accommodate (...) weakness of will, because they are inconsistent with agency, which requires free will, because ends, obligations and values cannot be reduced to desires, and because maximisation is often not possible. Further, Lester’s claim that agents are self-interested is vacuous, his attempted reduction of moral behaviour to want-satisfaction fails, and his contention, that agents always do what they genuinely think to be morally required, seems untenable. A defence of freedom that depends on homo economicus is far from promising. (shrink)
