Does the practice of psychology make a significant and positive contribution to human welfare and the struggle for a good society? This book presents a reinvigorating look at psychology and its societal purpose, offering a bold new philosophical foundation from which professionals in the field can deeply examine their work.

The article argues that universals of law, i.e. the laws of nature, are the general axioms of a deductive system of all knowledge, and their deductive consequences. Universals of fact are generalisations deducible from these together with particular facts.

The secession of prosperous regions may negatively affect the redistributive scheme of an established state. As a consequence, the capacity of its welfare system to support the inhabitants of poorer regions may be significantly reduced. Some authors assert that affluent groups who opt for full political independence violate duties of solidarity. This objection to the secession of prosperous regions can be based on different views of distributive justice. Here, following a distinction that has been introduced by Allen Buchanan, ‘subject centred’ (...) and ‘justice as reciprocity’ theories are explored. It is argued that both theories fail to support the case against the secession of wealthy groups. ‘Subject centred’ theories cannot explain special duties toward compatriots, whereas ‘justice as reciprocity’ theories cannot justify restrictions on exit rights. However, this does not mean that separatists have no moral duties vis-à-vis their fellow citizens. They are obliged to dissolve the political union in a fair way, e.g., by accepting responsibility for some share of the public debts. (shrink)

Kochen has suggested an interpretation of quantum mechanics in which he denies that wavepackets ever collapse, while affirming that measurements have definite results. In this paper I attempt to show that his interpretation is untenable. I then suggest ways in which to construct similar, but more satisfactory, hidden variable interpretations.

Since the early 1990s, politicians, policymakers, the media and academics have increasingly focused on religion, noting the significant increase in the number of cases involving religion. As a result, law and religion has become a specific area of study. The work of Professor Norman Doe at Cardiff University has served as a catalyst for this change, especially through the creation of the LLM in Canon Law in 1991 and the Centre for Law and Religion in 1998. Published to mark the (...) twenty-fifth anniversary of the LLM in Canon Law and to pay tribute to Professor Doe's achievements so far, this volume reflects upon the interdisciplinary development of law and religion.

I start off by relating the standard philosophical account of what time travel is to models of time travel that have recently been discussed by physicists. I then discuss some puzzles associated with time travel. I conclude that philosophers’ arguments against time travel are relevant when assessing the likelihood of the occurrence time travel in our world, and are relevant to the assessment whether time travel is physically possible.

The second volume of _Islam and Rationality: The Impact of al-Ghazālī_ brings together twelve leading experts in the field of Ghazālī-studies who write about his thought and the influence he had on later Muslim thinkers.

The strongest objection to (15) is that speaker's meaning is defined in terms of commitment, a notion which is itself something of a challenge and for which no definition has been given. This would be a strong reason to prefer a definition in terms of some more tractable concept, all things being equal; but it does not lessen the probability that commitment or some similar notion is indispensable to the definition of speaker's meaning.The philosophical writings discussed in this paper all (...) proceed something like this: Particular cases are discussed and a description is given of the mechanisms by which communication takes place. An attempt is made to say something that applies to all instances of speaker's meaning. Words like ‘analysis’, ‘account’ ‘explanation’, ‘explication’, and ‘theory’ are used here, the suggestion being that the objective is to provide for all cases at once what has already been provided for particular cases-an explanation of how meaning works. What is produced, however, looks like adefinition of speaker's meaning, a statement of necessary and sufficient conditions. This definition is then evaluated largely in terms of what counterexamples it does or does not allow.It seems that there is some tendency to conflate two quite distinct objectives: (i) a theory of speaker's meaning-a general description of how it is that speakers are able to communicate; and (ii) a statement of necessary and sufficient conditions for speaker's meaning. Objective (i) might plausibly be regarded as the goal of the study of communication. Objective (ii) is the definition of a certain intuitive, pretheoretical concept of meaning, which might or might not prove to be an important concept with respect to objective (i). The Gricean mechanism and the notion of conventional meaning, on the other hand, are indispensable to (i)-few instances of speaker's meaning could be adequately described without recourse to at least one of these notions. Thus nothing in this paper should be construed as trying to downgrade the importance of the Gricean mechanism for the theory of communication. If objective (ii) and the Gricean mechanism are not as closely associated as has been claimed, this is, if anything, a reason to doubt the importance of (ii) for the theory of communication.

Psychological experirnents have repeatedly shown that in judging the likelihood of uncertain events people do not follow the principles of probability theory. A notorious example is given by the so called conjunction fallacy. In this paper I argue that this fallacy is not really a fallacy when it is analysed in the light of a dynamic theory of default reasoning. The question that immediately rises is whether the fact that this theory conforms better to the way people actually think provides (...) a reason to prefer it to probability theory. (shrink)

According to the so-called metaphysical conception of analyticity, analytic truths are true in virtue of meaning (or content) alone and independently of (extralinguistic) facts. Quine and Boghossian have tried to present a conclusive argument against the metaphysical conception of analyticity. In effect, they tried to show that the metaphysical conception inevitably leads into a highly implausible view about the truthmakers of analytic truths. We would like to show that their argument fails, since it relies on an ambiguity of the notion (...) of 'independence of (extralinguistic) facts'. If one distinguishes between variation independence and existence independence, the unwelcome view about the truthmakers of analytic truths no longer follows. Thus, there is at best a challenge, but no conclusive argument. The door to the metaphysical conception of analyticity is still open. (shrink)

I present a “reduced” version of the fifteen Pragma-dialectical rules and inquire into their theoretical status as necessary conditions for a critical discussion. Questions: In what respect is PD’s non-sufficiency a deficiency, can and must it be remedied? Brief answers: with respect to defining the concept ‘critical discussion,’ possibly, yes, if, and only if, one seeks to identify the concept ‘critical discussion’; no, if PD is for fallacy-detection.
