Understanding terrestrial carbon metabolism is critical because terrestrial ecosystems play a major role in the global carbon cycle. Furthermore, humans have severely disrupted the carbon cycle in ways that will alter the climate system and directly affect terrestrial metabolism. Changes in terrestrial metabolism may well be as important an indicator of global change as the changing temperature signal. Improving our understanding of the carbon cycle at various spatial and temporal scales will require the integration of multiple, complementary and independent methods (...) that are used by different research communities. Tools such as air sampling networks, inverse numerical methods, and satellite data allow us to study the strength and location of the global- and continental-scale carbon sources and sinks. Bottom-up studies provide estimates of carbon fluxes at finer spatial scales and examine the mechanisms that control fluxes at the ecosystem, landscape, and regional scales. Bottom-up approaches include comparative and process studies that provide the necessary mechanistic information to develop and validate terrestrial biospheric models. An iteration and reiteration of top-down and bottom-up approaches will be necessary to help constrain measurements at various scales. We propose a major international effort to coordinate and lead research programs of global scope of the carbon cycle. (shrink)

The notion of whether people focus on the past, present or future, and how it shapes their behaviour is known as Time Perspective. Fundamental to the work of two of its earliest proponents, Zimbardo and Boyd (2008), was the concept of balanced time perspective and its relationship to wellness. A person with balanced time perspective can be expected to have a flexible temporal focus of mostly positive orientations (past-positive, present-hedonistic, and future) and much less negative orientations (past-negative and present-fatalistic). This (...) study measured deviation from balanced time perspective (DBTP: Zhang, Howell, and Stolarski, 2013) in a sample of 243 mature adults aged 45 to 91 years and explored relationships to Retirement Planning, Depression, Anxiety, Stress, Positive Mood, and Negative Mood. Results indicate that DBTP accounts for unexplained variance in the outcome measures even after controlling for demographic variables. DBTP was negatively related to Retirement Planning and Positive Mood and positively related to Depression, Anxiety, Stress and Negative Mood. Theoretical and practical implications regarding balanced time perspective are discussed. (shrink)

This book comprises an attempt to examine how we might set about an- swering the question: How much is society prepared to pay to reduce mortality: Or more brutally, what is the value of human life? The justification for attempting to answer such questions lies in the de- sirability of injecting increased explicitness and rationality into decision-making in those areas of the public sector which are con- cerned with life saving. Given that resources are already being de- ployed to such (...) activities as crash-barriers on motorways, helicopters for air-sea rescue, kidney machines and other life-saving measures - although such activities result only in a reduction in risk of death, not itsillimination, in the policy fields affected - this means that already at the present time, at least by implication, values are be- ing placed by decision-makers on the saving of life.

Providing health care in the most cost-effective way has become a priority in recent years. This book tackles the important issue of the potential conflict between economic expediency and the welfare of individual patients. Contributors examine different attitudes to this complex problem, along with a variety of legal and historical perspectives. The book addresses particular aspects of health care, such as medical expert systems, general practice, medical education, and clinical decision-making where the direct involvement of doctors in allocating scarce and (...) expensive resources is perhaps most obvious.

Recent theoretical developments in economic theory have attempted to relax the assumption that human behavior is guided by “tight calculation” of profit-maximization. Harvey Liebenstein's notion of X-efficiency is a particularly important development in this regard. This article argues, however, that X-efficiency theory does not go far enough in relaxing the assumptions of economic theory. The understanding of human behavior requires a recognition of variability in the ends or goals of action as well as variability in the means which are utilized (...) in the pursuit of these diverse ends. Max Weber's concepts of formal rationality and substantive rationality recognize this variability in the ends toward which action is oriented as well as the intrusion of habit or routine in the “calculatedness” of social and economic action. C. Wright Mills' ideal of craftship is used to represent a type of substantive rationality which contrasts with the formal rationality of calculation toward profit-maximization. The case is made that craftship is a particularly significant substantive rationality in American agriculture. It is argued that, among family farmers, other values, such as autonomy in one's work, often constitute alternative ends toward which action may be directed. Such ends may, in fact, conflict with the goal of profit-maximization. It is concluded that agricultural policy analysis and prescription which fails to consider the significant role of substantive rationalities, such as craftship, are likely to reproduce and enhance the conditions from which the present crisis in agriculture has developed.

In a famous debate on jurisprudence held in 1958 between H. L. A. Hart and Lon Fuller, the protagonists argued about the nature of the law. On one side was H. L. A. Hart, who was a staunch defender of two ideas, first, that law was to be separated from morals, and secondly, that law as it is should be separated from law as it ought to be. These two ideas are subtly different. On the other side, is Fuller, who (...) argues that law cannot be understood apart from its reason for being formulated in the first place. In relation to Hart's two ideas, the paper shows how both rest upon an unstated hidden motivating assumptions, clues to which can be found in both "Positivism and the Separation of Law and Morals" and 'The Concept of Law'. This assumption is that Hart is committed to a distinctively liberal account of morality which finds expression in the rule of law. The paper argues that the project of finding a purely descriptive account of law is impossible in the Hartian sense since the descriptive/evaluative dichotomy is a false dichotomy. This is achieved by means of the Kovesian analysis of concept formation. (shrink)

A promise to do some action seems to create a binding obligation to do that action. And yet, paradoxically, an obligation seems not to be a fact that we can create or bring into existence; we can create an obligation only by creating or bringing into existence something else. The only way to avoid the paradox is to show that the act of promising creates something other than an obligation, which nonetheless binds us to perform the action in question. After (...) considering and rejecting various options such as the promisee's expectation and the promisor's resolve, Prichard locates the bindingness of a promise in a prior general promise, which allows the noises we make when promising to generate an obligation to perform the promised action.

The author joins the discussion on selection of patients in the face of life-saving resources initiated in the Journal by Parsons and Lock, Mooney and the editorial in the December 1980 issue. In this article several selection systems are discussed. The author is in favour of a `criteria-system'. The criteria for such a system are elaborated. On the basis of a sequence of values a sequence of criteria is proposed. Attention is also given to the procedural aspects.

To the question ‘What does it mean to act or to do something?’, replies that it is not easy to identify a common character in actions. Begins by examining the position of Cook Wilson, who maintains that ‘to do something’ means to originate, cause, or bring into existence, either directly or indirectly, some not yet existing state either in oneself or some other body. Although Prichard agrees that usually action involves causing something, he observes that causing a change is not (...) itself an activity. In moving one's hand, one performs that indefinable mental activity of willing some change. The movement of the hand is the effect of the action, not the action itself, a fact overlooked by thinkers like Locke. Turning to the nature of the desire behind one's willing, Prichard rejects the view that this desire is actually a desire for the change willed. Despite forceful objections, Prichard maintains that this desire is the desire for the willing of that change. (shrink)

Prichard's concern here is whether a person's obligation depends either on features of his or her situation or on features of his or her thoughts about that situation. Related to this contrast between the objective view and the subjective view is the issue of whether an obligation is an obligation to do some action. To the latter issue, Prichard responds that an obligation is not an obligation to do something, but an obligation to set ourselves to do something; as a (...) consequence, it is necessary to modify the terms of Prichard's primary concern. This modification diminishes the force of the objective view and does nothing to eliminate the central difficulty in the subjective view, namely, that the obligation to do some action is said to depend not on the character that the action would have, but on our belief that it would have that character. The belief that some general character picks out obligations derives from the mistaken habit of regarding the terms ‘right’ and ‘wrong’ as equivalent to ‘ought’ and ‘ought not’. Having highlighted this mistake, Prichard holds that in instances where we have considered the circumstances fully, our thoughts about the situation decide whether we ought to perform a given activity. (shrink)

Maintaining that the existence of Moral Philosophy, as it is usually understood, rests on a mistake, Prichard undertakes to formulate our true attitude towards moral obligations. The right action does not depend upon either our own good or what is good. Obligations are underivative, immediate, and self‐evident, and therefore, we do not come to appreciate them through argument or a process of non‐moral thinking. The mistake on which Moral Philosophy rests, which links obligation to virtue or desire, parallels the mistake (...) underpinning the Theory of Knowledge. Like moral obligation, knowledge is immediate; it need not be vindicated or improved by additional knowledge. (shrink)

The act of exchanging one thing for another seems to involve a promise. The confidence needed to relinquish something one has on the understanding that one will receive what another has in exchange can be expressed in terms of resolve. In binding oneself, one thinks that if the other binds himself or herself to perform a given action, then he or she will do that action. In cases in which one person's action does not precede the other's, one's promise involves (...) thinking that if the other binds himself or herself, then he or she will carry out the promised action. (shrink)

In his general account of moral thought, Prichard holds that to regard a given action as right, we must imagine ourselves to be in a certain set of circumstances. In doing so, we conceive of ourselves as bound by those circumstances to perform that action. Since we have various general convictions about moral obligation, no single characteristic leads us to regard right acts as right. When two general convictions conflict, we are not in a position to know what our duty (...) is. Being ignorant of some relevant circumstances, we cannot answer the question ‘What ought we to do?’ This follows from the fact that no common characteristic renders actions into duties. (shrink)

Concerning the nature of desires that pertain to actions, considers the view that we cannot desire something unless we know or think, first, that it does not exist, and second, that it does not exist now. Finds a core of truth in this, but modifies the formula to claim that ‘we can only desire the existence of that of the existence of which in the past, present, or future, as the case may be, we are uncertain.’ Put more simply, a (...) desire is not a desire for the existence of something, but rather a desire for something to be. It follows from this view that we cannot desire something to be the case when we think that, without a doubt, it will be the case. (shrink)

Examines four principle questions about moral obligation raised by key philosophers: Plato asks in The Republic ‘Will a man be better off for doing his duty?’; Plato then asks ‘Ought man to do his duty?’; we may also ask ‘What is the criterion of a duty?’; and we may ask ‘What is moral obligation?’ Rejecting the last question as unreal, Prichard then argues against the connection between duty and happiness or duty and personal or general advantage. After critiquing both teleological (...) and quasi‐teleological theories of obligation, he ends by contrasting goodness and obligation. (shrink)

To the many moral theorists who have sought to establish a necessary connection between duty and interest, Prichard replies that their project ought not to be undertaken as it commits us to the view that our only duty is to do what is to our advantage. In discussing the attempts of Plato, Butler, and Green to link duty and interest, Prichard, like Kant, maintains that the rightness of action does not depend either upon our own good or upon our belief (...) that it depends upon our own good. Similarly, Prichard dismisses the view that our desire for our own good is our only motive. (shrink)

Analyses Green's rather obscure treatment of two important questions: ‘Why does a subject have the duty to obey the ruler or sovereign?’; and ‘Why is the receipt of an order backed by a threat sufficient to establish this duty when the order comes from a ruler?’ Prichard considers Green's position regarding the grounds and justification for obedience to law to be part of a larger theory of moral obligation that is inconsistent with our ordinary moral ideas. To Green's seeming denial (...) of the existence of any natural rights or duties, Prichard responds that Green in fact has failed to state a sense in which there really are natural rights and obligations. Moreover, Green's denial that we can answer the question ‘Why ought we to obey the government?’ can be formulated only by maintaining the existence of an obligation independent of our government's commands. The core of truth in Green's position, according to Prichard, lies in his recognition that a factor necessary to secure obedience is the subject's unselfish interest in the welfare of other members of her community.

Discusses central aspects of Kant's work on the nature of morality and the basis of moral obligation. In examining the categorical imperative and the hypothetical imperative, emphasizes the real nature of the distinction between these principles: whereas the former is binding upon every one, the latter is binding only upon some individuals, namely those individuals who want the end for which a prescribed action is a means. Also considers the nature of the will, Kant's criterion of the rightness of a (...) right action, and two criticisms of Kant's view of morality that arise from his attempt to offer a general answer to the question ‘Why ought an action be performed?’ Then turns to Kant's proof of freedom, which it is claimed just barely misses making the right point that action is only possible under the idea of freedom. Concludes by examining Kant's proof of immortality and the existence of God. (shrink)

Prichard's topic here is the nature of ‘ought’. If we were to take ‘I ought to will x’ to be equivalent to ‘my willing x ought to exist’, then it is true that ‘If I were to will a certain change x, my willing x would be something that ought to exist.’ For this to hold, either my willing x would itself be something good or my willing x would cause something good. Prichard, however, rejects this view on the grounds (...) that one cannot know, in willing x to exist, whether one's willing x is something that ought to exist. One can only know that if one were to will x, one would be willing something that one thought ought to exist. (shrink)

Endeavours to specify what Aristotle means by αγαθον. In some contexts, this term seems to mean simply ‘that being desired’ or a person's ultimate or non‐ultimate end or aim. In other contexts, αγαθον takes on a normative quality. For his statements to have content, argues Prichard, Aristotle must hold that when we pursue something of a certain kind, such as an honour, we pursue it as a good. Prichard argues that by αγαθον Aristotle actually means ‘conducive to happiness’, and holds (...) that when a man acts deliberately, he does it from a desire to be happy. Prichard attributes this position to Plato as well, despite the fact that both thinkers make statements inconsistent with this view of our ultimate aim. (shrink)

Often an action causes both evil and benefit for the agent. No general account can be given for what happens when one considers in light of this evil and benefit whether to undertake the action in question. Prichard maintains that in willing a movement, there are two acts of will. First, there is the willing to think more of what one shall gain in willing x, which results from the desire to will x. Second, there is the willing of the (...) change x. (shrink)

To ascertain the truth about the main problems of moral philosophy, Prichard begins by dismissing as unreal the question ‘What is moral obligation?’ Being sui generis, ‘moral obligation’ cannot be defined in terms of other things. We are left with the question ‘What makes right acts right?’, to which Prichard replies there is no general answer. We are also left with the question ‘What, if anything, ought we to do in life?’ After contrasting the moral and the non‐moral senses of (...) ought, Prichard replies to Sidgwick's utilitarian treatment of this question, which involves dividing the question into two: ‘What ought I to do?’ and ‘What ought I to aim at?’ Dismissing the latter formulation, Prichard defends an intuitionist account of how we come to know what we ought to do. He concludes by distinguishing between the right and the good. (shrink)

In discussing the fact that it takes time to perform an action, distinguishes statements such as ‘I shall do x’ from statements such as ‘I shall be under an obligation to do x’ and ‘I was doing x’ from ‘I was under an obligation to do x’. The truth of the ‘ought’ statements is independent of whether the action is done, as it is not necessary that one not do the action at the time required in order to be under (...) an obligation to do it at that time. For some contrasts between ‘ought’ and ‘is’ statements, the obligation, such as the obligation to go to bed, refers to the future. The statement ‘I am under an obligation to go to bed’ is equivalent to ‘from now on I shall be under an obligation to go to bed’, and does not require either that I shall not do the action or that I have not done the action for it to be true.

What role does the wild duck play in Ibsen's famous drama? I argue that, besides mirroring the fate of the human cast members, the duck is acting as animal subject in a quasi-experiment, conducted in a private setting. Analysed from this perspective, the play allows us to discern the epistemological and ethical dimensions of the new scientific animal practice (systematic observation of animal behaviour under artificial conditions) emerging precesely at that time. Ibsen's play stages the clash between a scientific and (...) a romantic understanding of animals that still constitutes the backdrop of most contemporary debates over animals in research. Whereas the scientific understanding reduces the animal's behaviour, as well as its environment, to discrete and modifiable elements, the romantic view regards animals as being at one with (or violently disconnected from) their natural surroundings.

Speeches of the author on theory of knowledge in the context of Islamic philosophy.

Probably to most students of Moral Philosophy there comes a time when they feel a vague sense of dissatisfaction with the whole subject. And the sense of dissatisfaction tends to grow rather than to diminish. It is not so much that the positions, and still more the arguments, of particular thinkers seem unconvincing, though this is true. It is rather that the aim of the subject becomes increasingly obscure. "What," it is asked, "are we really going to learn by Moral (...) Philosophy?" "What are books on Moral Philosophy really trying to show, and when their aim is clear, why are they so unconvincing and artificial?" And again: "Why is it so difficult to substitute anything better?" Personally, I have been led by growing dissatisfaction of this kind to wonder whether the reason may not be that the subject, at any rate as usually understood, consists in the attempt to answer an improper question. And in this article, I shall venture to contend that the existence of the whole subject, as usually understood, rests on a mistake, and on a mistake parallel to that on which rests, as I think, the subject usually called the Theory of Knowledge.

On Sikh doctrines inunciated by Guru Nanak.

In this paper, I will reread the history of molecular genetics from a psychoanalytical angle, analysing it as a case history. Building on the developmental theories of Freud and his followers, I will distinguish four stages, namely: (1) oedipal childhood, notably the epoch of model building (1943–1953); (2) the latency period, with a focus on the development of basic skills (1953–1989); (3) adolescence, exemplified by the Human Genome Project, with its fierce conflicts, great expectations and grandiose claims (1989–2003) and (4) (...) adulthood (2003–present) during which revolutionary research areas such as molecular biology and genomics have achieved a certain level of normalcy—have evolved into a normal science. I will indicate how a psychoanalytical assessment conducted in this manner may help us to interpret and address some of the key normative issues that have been raised with regard to molecular genetics over the years, such as ‘relevance’, ‘responsible innovation’ and ‘promise management’.
