Effort is then well-nigh indescribable. Not wholly so, else it would be meaningless. Description is a matter of degree: who can fully describe red or wet? To be sure, description comes down in the end to the pointing to certain given qualities or relations or events which are just there. All connotation rests on denotation, though it may be something more. But the unique positive thing about effort is its originality; to which indeed we can point, since every one experiences (...) it in himself. Yet common to all men though it is, it is so intangible! more spirit than body, more force than substance. We should perhaps best call it not a datum but a factum, or better still, a fiat, a doing rather than a deed, yet not merely a becoming, for we see things coming to be, we hear a melody progressing and touch a moving object. Effort, dynamic as it is, is not just the process, rather it is--we must re-iterate--the start, the initiative of the process. Nor is the experience of it properly called mystical. Even if mystical experience were indescribable, as has been wrongly alleged, these would be two quite different indescribables, the one receptive, the other originative. All we can say perhaps is that effort is analogous to the push that starts the ball rolling, not the motion of the ball, not the acceleration, but the enforcement of these. Its witness does not lie in its value as explanation of the motion; the witness is direct, the immediate experience which every man has. It seems to be no object of scientific investigation in the technical sense. It cannot be measured by itself, as acceleration and motion are measured. That is why physics has abandoned the old notion of force, the physical analogue of effort, replacing it by mass-acceleration. That is why the rationalists in modern philosophy look askance at this direct experience of man, so intangible that we can draw from it no logical implications. For it has no structure. Its characteristic is not clearness nor distinctness. We might be tempted to say it is like a point in space, too small to be envisaged, yet not a zero; but it is more like a dot or spark, so small as to be just seen, so small as to have no visible spread, no content that we can analyze to draw out rational consequences connecting it with other things. Here too we see why the contemplative thinker seldom believes in free choice, which the natural man naturally accepts. Free choice is the kind of thing that might well belong to this experience; free choice is origination. Not necessarily that all effort is freely made. The baby exercises no free choice when he sucks hard at the nipple, nor the adult when he wrestles for his life with an enemy. But they want, need, desire; that is the point. Desire--that is the essence of effort. Desire has the originative quality; it comes as it were out of one's self and from no other source, it is what we want, our self insisting on its own. But the business is so deep within that it is easily overlooked, or deliberately excluded from the gaze, and without a qualm. We might say it is too near to be noticed, or too deep down to obtrude itself, as the water in the well is easy to see, but not the spring at the bottom of the well. Effort disappears from the scene when the thinker is calmly gazing; but when he acts it is felt, and strongly felt. It is in fact the very essence of the self, the well-spring of its worth and its growth. A man is what he does. His worth lies in what he makes. All that he is responsible for, all that he earns, is credited with, or guilty of, comes from this innermost source. So thinks the practical man, so we all believe when we are conducting our lives in intercourse with one another and with nature. But for the contemplative attitude there is here too little of clear articulation, of object-matter for analysis; no use can be made of it in a deductive system. So the system-builders discard it.

This paper considers the relationship between G. H. von Wright's solution to the paradoxes of confirmation and his "Principal Theorem of Confirmation". The former utilizes the order of our knowledge of the qualities of confirming instances of an hypothesis; the latter states the way in which an instance contributes to the probability of an hypothesis. It is shown that these two, as stated by von Wright, are logically incompatible. Then the most thorough possible emendation of the paradoxes solution is considered, (...) and it is shown that this still prohibits use of the "Principal Theorem" to confirm hypotheses stating necessary causal conditions, and to confirm by deliberate experiment hypotheses stating sufficient causal conditions. It is concluded that any solution of the paradoxes must rest solely upon the relation of the data to the hypothesis involved. (shrink)

Common eigenfunctions of nontrivial projectors of x and p are constructed.

L'A. soutient, contre Germain Grisez, Joseph Boyle, John Finnis et William May, que le contrôle naturel des naissances pratiqué avec une intention mauvaise n'est pas contraception. Il montre que les auteurs identifient de façon incorrecte la fin prochaine de la contraception comme choix qu'il n'y ait pas d'enfant, alors que la fin prochaine véritable est d'empêcher un enfant de venir au monde . Ainsi donc, puisque en NFP un couple ne cherche pas à empêcher la venue au monde d'un enfant, (...) NFP n'implique pas d'action contraceptive. L'A. soutient aussi qu'identifier la fin prochaine comme choix qu'il n'y ait pas d'enfant ne spécifie pas de façon adéquate une classe homogène d'actes objectifs, bien que cela spécifie une classe homogène d'actes moraux.

For two hundred years, Americans have believed that they have an obligation to improve the lot of humanity, a belief that has consistently shaped U.S. foreign policy. Yet within this consensus, there are two competing schools of thought: the "exemplarist" school (Brands' term) which holds that what America chiefly owes the world is the benign example of a well-functioning democracy, and the "vindicationist" school which argues that force must sometimes supplement a good example. In this book, H.W. Brands traces the (...) evolution of these two schools as they emerged in the thinking and writing of the most important public thinkers of the past two centuries. (shrink)

In One Priest argues for the contradictoriness of Unity. The argument is that the unity of complex things is contradictory. It is contradictory that there are complex wholes composed of many parts. But there are. Thus, the explanation of unity has to be a contradictory entity, a gluon, which both is and is not an object. The book then develops and utilises a theory of gluons. The argument for the contradictoriness of Unity is crucial; without it there is no motivation (...) for the theory of gluons. It fails. It does so because ‘because’ is a sentential connective. So what follows it must be a sentence, not a list. So Priest is wrong to say that in a complex whole there must be something, an entity, which binds the parts together. (shrink)

Objective: To determine the views of people with multiple sclerosis (MS) and professionals in relation to confidentiality, consent and access to data within a proposed MS register in the UK. Design: Qualitative study using focus groups (10) and interviews (13). Setting: England and Northern Ireland. Participants: 68 people with MS, neurologists, MS nurses, health services management professionals, researchers, representatives from pharmaceutical companies and social care professionals. Results: People with MS expressed open and altruistic views towards the use of their personal (...) information to facilitate service provision and research, placing trust in responsible guardianship and legitimate use of their information. Participant’s proposed that people with MS should be able to select their individual level of involvement in a register using levels of consent. It was agreed that access to the register should be governed by a guardianship committee composed of a range of stakeholders. People with MS did not wish their details to be used by marketing agencies and did not consider this a legitimate use of their data. Whilst participants were positive of the role a register could play in promoting research, participants felt that access to data by pharmaceutical industries should be administered by the guardianship committee. People with MS are concerned should their employers be able to access their personal information. Professionals were more cautious than people with MS in their approach to the use of patient personal data within a register. Conclusions: Whilst all stakeholders were positive of the benefits of an MS register, development of such a resource must incorporate robust data security and guardianship measures in order to ensure that, whilst opportunities are maximised, risks to the privacy of individuals and legal challenges to professionals are avoided.
