Since the time, about a century ago, when DeMorgan, Boole and Jevons, inaugurated the study of the logic of numerically definite reasoning, no one has been concerned to establish the validity rules for a very general type of numerically definite inference which is a strong analogue of the classical syllogism. The reader will readily agree that the traditional rules of syllogistic inference cannot even begin to decide whether the following proportionally quantified syllogism is a valid argument: at most 4/7 p (...) are at most 2/3 not-m and at least 3/5 s are precisely 7/8 m, hence, at most 1/3 s are p. Likely reasons, of broad methodological interest, why this readily definable type of formal inference has been neglected will presently be proposed. Among the masters of twentieth century logic, Hilbert and Bernays have, to be sure, meticulously shown how such numerically definite propositions as “at least 7 individuals have the property p” can be expressed in the predicate calculus with the use of the identity relation. They do not, since their concern with such propositions is indirect, proceed to establish a systematic calculus of classes whose “size” or extent is numerically definite. As we shall always notice, traditional logic and even ordinary Boolean algebra prefer to generalize about the laws governing the interrelationship of classes in inference systems without making any hypotheses concerning class “size” or extent except by the classical quantifier “some”, which quantifier admits the measure or extent of a class only in terms of the proposition that a given class contains or does not contain at least one member. Such a restricted admission of the relevance for inference of class size is among the fundamental reasons for the neglect of proportional quantifiers, i.e., quantifiers where numerical value is any rational number r such that 0/100 ≤ r ≤ 100/100. It can, of course, also be pointed out that the traditional syllogism and ordinary Boolean algebra do not i.e. measure, numerically define, the degree of inclusion of one class in another. Inclusion is taken either as total or partial, with no discrimination of the degree of partial inclusion. (shrink)

The primary aim of the current study was to examine whether depleted cognitive resources might have ramifications for the formation of neutral and negative spontaneous false memories. To examine this, participants received neutral and negative Deese/Roediger–McDermott false memory wordlists. Also, for half of the participants, cognitive resources were depleted by use of an ego depletion manipulation . Our chief finding was that depleted cognitive resources made participants more vulnerable for the production of false memories. Our results shed light on how (...) depleted cognitive resources affect neutral and negative correct and errant memories. (shrink)

Experimental observations are often taken in order to assist in making a choice between relevant hypotheses ∼ H and H. The power of observations in this decision is here metrically defined by information-theoretic concepts and Bayes' theorem. The exact (or maximum power) of a new observation to increase or decrease Pr(H) the prior probability that H is true; the power of that observation to modify the total amount of uncertainty involved in the choice between ∼ H and H: the power (...) of a new observation to reduce uncertainty toward the ideal amount, zero; all these powers are systematically shown to be exact metrical functions of Pr(H) and Pr(o/H)/Pr(o)-1 where the numerator is the likelihood of the new observation given H, and the denominator is the "expectedness" of the observation.

For a generation increasingly fragmented by a glut of unassimilable information and unrelated "facts", "Wittgenstein" from The Element Masters of Philosophy series focuses on his groundbreaking perspective of understanding concepts.

ObjectiveHead and neck cancer treatments are known to significantly affect functionality and appearance, leading to an increased risk for body image disturbances. Yet, few longitudinal studies exist to examine body image in these patients. Based on a conceptual model, the current study aimed to determine, in patients newly diagnosed with HNC: the prevalence, level, and course of body image concerns; correlates of upon cancer diagnosis body image concerns; predictors of immediate post-treatment body image concerns; and association between body image concerns (...) and levels of anxiety, depression, suicidal ideation, support, and alcohol and drug misuse.MethodsTwo hundred and twenty-three, newly diagnosed with a primary HNC were assessed using structured clinical interviews and psychometric measures at three, and 6 months after diagnosis. Primary outcome was 3-month, as it was most salient to body image disturbance. Multiple linear regression analyses were conducted on the potential body image predictors, based on the model.ResultsSixty-eight percent of patients with HNC presented some level of body image concerns. Body image concerns at baseline and post-treatment were significantly related and significantly increased from pre- to post-treatment. Immediately post-treatment, 89% presented some level of body image concerns. Correlates of body image concerns in patients with HNC at baseline included: physical symptom burden, difficulties with communication and eating, coping with the cancer diagnosis using denial, suicidal ideation, and having had a past anxiety diagnosis. When controlling for sociodemographic and medical variables, body image concerns in patients with HNC in the immediate post-treatment were predicted by: baseline body image, physical symptom burden, and neuroticism.ConclusionThis longitudinal study helps identify patients more susceptible to experience body image disturbance following head and neck cancer. Clinicians ought to pay special attention to body image concerns upon cancer diagnosis, physical symptom burden, and neuroticism, and may want to target these factors in future preventive interventions.

Ce livre [...] semble être écrit dans le langage d'un vent de dégel : on y trouve de la pétulance, de l'inquiétude, des contractions et un temps d'avril, ce qui fait songer sans cesse au voisinage de l'hiver, tout autant qu'à la victoire sur l'hiver, à la victoire qui arrive, qui doit arriver, qui est peut-être déjà arrivée... La reconnaissance rayonne sans cesse, comme si la chose la plus inattendue, ce fut la guérison. " Gai savoir " : qu'est-ce sinon (...) les saturnales d'un esprit qui a résisté patiemment, sévèrement, froidement,, sans se soumettre, mais sans espoir, - et qui maintenant, tout à coup, est assailli par l'espoir de guérison, par l'ivresse de la guérison? [...] " Incipit tragaedia " - est-il dit à la fin de ce livre d'une simplicité inquiétante : que l'on soit sur ses gardes! Quelque chose d'essentiellement malicieux et méchant se prépare : incipit parodia, cela ne laisse aucun doute... Friedrich Nietzsche Ecrit entre 1881 et 1887, publié une première fois en 1882, dans une version incomplète, repris et parachevé ensuite. Le Gai Savoir confirme et conforte le radicalisme nietzschéen. Les grands thèmes de sa réflexion sont désormais parvenus à leur pleine maturité. L'idéal, la nécessité de l'héroïsme en philosophie, l'analyse de la décadence, mais aussi le principe de l'éternel retour, le mythe de Zarathoustra, la connaissance, la religion c'est un véritable bréviaire du " nietzschéisme " qui apparaît au fil des pages.
