Avicenna on the Law of Non-contradiction

Aristotle gave seven arguments for the law of non-contradiction. The first one is against a special case of dialetheism, the view that only some contradictions are true, and other six arguments are mostly against trivialism, the view that everything and consequently every contraction is true. Aristotle never argued that dialetheism entails trivialism. Unlike Aristotle, Avicenna, in his defense of LNC, not only considers trivialism and argues against it, but also argues that dialetheism entails trivialism. The argument that dialetheism entails trivialism is called explosion. It is usually known that the first argument for explosion is given by the twelfth century logician William of Soissons. In this paper, we will meet Avicenna’s different argument for explosion and then I will demonstrate that this argument is a non-sequitur.

Noninvasive measurement of smokers’ tar and nicotine intake

A simple device for monitoring cigarette smokers’ intake of tar and nicotine is described. This device divided the mainstream smoke into two parallel paths, one containing seven parallel capillary tubes and the other containing one capillary tube; a Cambridge filter trapped the smoke passing through the path containing one tube. Analyses of both tar and nicotine trapped in the filter were performed by gravimetric and chemical methods. Calibration tests verified that a constant fraction of the tar and nicotine was retained in the apparatus over a wide range of conditions, allowing the calculation of smoke intake into the mouth. With supplementary methods for measuring the amount of smoke exhaled, the apparatus can be used to measure smoke deposition in the respiratory tract.

Multidimensional Inventory for Religious Spiritual Well-Being (MI RSWB 48): Validation with Iranian psychiatric outpatients

ABSTRACT

The aim of this study was to investigate the validation of the Multidimensional Inventory for Religious Spiritual Well-Being (MI RSWB 48) in a convenience sample of 250 Iranian psychiatric outpatients. In addition to the MI RSWB 48, the patients completed the Spiritual Well-Being Scale (SWS), the WHO-5, the PHQ-9, and the PHQ-15. Cronbach’s α for the MI RSWB 48 was .84, and for its subscales ranged from .33 (Hope Transcendent [HT] Subscale) to .89 (General Religiosity [GR] Subscale). The SWS score had the highest positive correlation with the MI RSWB 48 score. Two factors identified for the scale. The religiosity spirituality score of female patients was significantly higher than the score of the male patients. The MI RSWB 48 can be considered as a suitable tool for evaluating different aspects of religiosity and spirituality in Iranian society. The HT Subscale may need modification to improve its internal consistency.     

To Recycle or Not to Recycle? An Intergenerational Approach to Nuclear Fuel Cycles

This paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and proliferation concerns. However, it compromises short-term public health and safety and security, due to the separation of plutonium. The trade-offs in nuclear energy are reducible to a chief trade-off between the present and the future. To what extent should we take care of our produced nuclear waste and to what extent should we accept additional risks to the present generation, in order to diminish the exposure of future generation to those risks? The advocates of the open fuel cycle should explain why they are willing to transfer all the risks for a very long period of time (200,000 years) to future generations. In addition, supporters of the closed fuel cycle should underpin their acceptance of additional risks to the present generation and make the actual reduction of risk to the future plausible.     

The Factor Structure of the Twelve Items General Health Questionnaire (GHQ-12): a Population Based Study

Mental health is a key component of general health based on world health organization (WHO) definition of health. A short form of the general health questionnaire (GHQ-12) has been widely used as an assessment tool of general and mental health. This study was designed to evaluate the properties of the Persian version of this questionnaire. Of 6140 subjects aged 10–90 years of a cohort study of Northern Iran, the relevant data of 5074 individuals aged ≥18 years were considered for analysis. Confirmatory factor analysis was conducted to evaluate the six models including one-dimensional model, one-dimensional model with correlated errors on negative items, two-dimensional model based on negative and positive statement items, two-dimensional model based on social dysfunction and psychological distress, three-dimensional model based on anxiety/depression, social dysfunction and loss of confidence and finally one-dimensional model with an additional factor for the negatively phrased items. The best fit indices belonged to one-dimensional model with correlated errors on negative items with χ2 = 686.8, df = 39, CFI = 0.953, RMSEA = 0.057 (95%CI: 0.054–0.061), SRMR = 0.0317, AGFI = 0.952, TLI = 0.920 and AIC = 764.8 and also three-dimensional model with χ2 = 860.7, df = 51, CFI = 0.941, RMSEA = 0.056 (95%CI: 0.053–0.059), SRMR = 0.0343, AGFI = 0.955, TLI = 0.923 and AIC = 915.0. In the comparison between these two best models we had ?χ2 = 174.2, ?df = 12, p-value < 0.001 in favor of the one-dimensional model. One-dimensional model with correlated errors on negative items showed the best fitting indices with our population.     

Contested Technologies and Design for Values: The Case of Shale Gas

The introduction of new energy technologies may lead to public resistance and contestation. It is often argued that this phenomenon is caused by an inadequate inclusion of relevant public values in the design of technology. In this paper we examine the applicability of the value sensitive design (VSD) approach. While VSD was primarily introduced for incorporating values in technological design, our focus in this paper is expanded towards the design of the institutions surrounding these technologies, as well as the design of stakeholder participation. One important methodological challenge of VSD is to identify the relevant values related to new technological developments. In this paper, we argue that the public debate can form a rich source from which to retrieve the values at stake. To demonstrate this, we have examined the arguments used in the public debate regarding the exploration and exploitation of shale gas in the Netherlands. We identified two important sets of the underlying values, namely substantive and procedural values. This paper concludes with two key findings. Firstly, contrary to what is often suggested in the literature, both proponents and opponents seem to endorse the same values. Secondly, contestation seems to arise in the precise operationalization of these values among the different stakeholders. In other words, contestation in the Dutch shale gas debate does not arise from inter-value conflict but rather from intra-value conflicts. This multi-interpretability should be incorporated in VSD processes.     

The Sufi Path of Dialetheism: Gluon Theory and Wahdat al-Wujud

The theory of Wahdat al-Wujūd, or as it is called in English the Oneness of Being, is the core idea of Sufism. The founder of this theory is Ibn ‘Arabī. There are contradictions in Ibn ‘Arabī’s theory of the Oneness of Being. The most important one, which is my main concern in this essay, occurs in his explanation of the relation between Being, which is, according to him, the only real being, and other beings. According to Ibn ‘Arabī, Being is identical and also non-identical with beings. Different philosophers, through hundreds of years, tried to dissolve such contradictions, by proposing consistent readings of Ibn ‘Arabī’s theory of the Oneness of Being. I will not follow this path. Instead, I take the theory of the Oneness of Being to be a dialetheic one, that is, according to this theory there are true contradictions. Thus, I claim that one can have a paraconsistent semantics of the theory of the Oneness of Being. To do so, I appeal to Graham Priest’s Gluon theory. Gluon theory concerns the problem of unity, that is, what makes the plurality of an object’s parts into a whole? I give a translation of the theory of the Oneness of Being into Gluon theory, and show how Gluon theory explains the theory of the Oneness of Being.
