«Neither with you nor without you»Francois Truffaut, La femme d’à coté No one can deny that there is a problem between Wittgenstein and analytic philosophers. To put it mildly, there are tensions between Wittgenstein’s and Wittgensteinian styled reflections and the views and practice of a lot of contemporary analytic philosophers, such that they often seem to be strange bedfellows, when they are bedfellows at all. Of course we know that Wittgenstein did not get along very well with Russell, t...

This paper argues that narrative elements from the science fiction (SF) literary genre are used in the discourse of Nanoscience and Technology (NST) to bridge the gap between what is technically possible today and its inflated promises for the future. The argument is illustrated through a detailed discussion of two NST texts. The paper concludes by arguing that the use of SF narrative techniques poses serious problems to the development of a critical analysis of the ethical and social implications of (...) NST. (shrink)

Mīr Dāmād, in Qabasāt argues that existence cannot be a real property for essences. If existence, he argues, were a real property of an essence, there would remain no distinction between simple-if and compound-if questions. It is well-known that Mullā Sadrā has given three different accounts in order to explain essence’s being existent: first that existence is an analytical property for essence; second that none of existence or essence is a property of the other one; and third that essence is (...) a property of existence. In this paper, I will argue that the first account would be defeated by Mīr Dāmād’s argument. The second account concedes the conclusion of the argument and then it would be in contrary with Mullasadra’s own view on the reality of existence, unless this account is augmented with the third one. The third account, however, can evade the argument. But it should be noted that the third account is based on Mullasadra’s own view on the reality of existence and the primacy of existence to essence. Keywords: existence, to be existent, simple-if question, compound-if question, property. 1. Introductıon In al-’Ufuq al-Mubīn Mīr Dāmād claims that not all predicates of a subject manifest a real property for that subject. A real property of a subject is something which is superadded to the subject. Examples include a body’s being red or a body’s being above another body. In such cases, the predicates correspond with some feature of the subjects which are not the same as those subjects, in reality. This is opposed to the body’s being itself, for example. In this case, the body itself is not something which is superadded to the body. 2. Mīr dāmād agaınst the realıty of exıstence The controversial example is essence’s being existent. Is the existence of an essence something superadded to the essence? In Mīr Dāmād’s words, is existence a real property for essence? Mīr Dāmād, in Qabasāt argues that existence cannot be a real property for essences. For this end, he notifies that there is a distinction between propositions that is parallel to the distinction between real and non-real properties. If P is a real property for a, then the proposition that a is P is a compound-if proposition. On the other hand, it is a commonplace that the only example of simple-if propositions is one that contains existence as its predicate. Now, he continues, suppose that existence is a real property. Then, the proposition that a exists would become a compound-if proposition. But this contradicts the well-established premise that the proposition that a exists is a simple-if proposition. Consequently, he argues, if existence were a real property of an essence, there would remain no distinction between simple-if and compound-if questions. The major problem that Mīr Dāmād is dealing with is how to explain essence’s being existent. His view is that, in reality, essence’s being existent is nothing but the essence itself. He, then, goes a step forward and claims that existence is nothing in reality. We only have the concept of existence in our minds. With these moves Mīr Dāmād, in some sense, resolves the problem of the relationship between essence and existence, in reality. 3. Mullā sadrā on the relatıonshıp between exıstence and essence It is well-known that Mullā Sadrā, Mīr Dāmād’s pupil, was in disagreement with the teacher with respect to the reality of existence. He believes that existence is a real entity in the world as opposed to essence. So, he should explain how essence is existent. Actually, he has given three different accounts in order to explain essence’s being existent. Mullā Sadrā’s first account is that existence is an analytical property for essence. He defines analytical property as the following: P is an analytic property for a iff a cannot be but not has P. Mullā Sadrā’s second explanation is that none of existence or essence is a property of the other one. His third thesis is that essence is a property of existence. 4. Mullā sadrā v.s. mīr dāmād My major concern in this paper is this problem: which of these three accounts for essence’s being existent offered by Mullā Sadrā can overcome Mīr Dāmād’s seminal argument? The first account would be defeated by Mīr Dāmād’s argument, since, any kind of real property, whether it is analytical or not, are associated with a compound-if proposition. This causes essence’s being existent to be manifested by a compound-if proposition. The second account concedes the conclusion of the argument. As we saw, Mīr Dāmād claims that the conclusion of his argument guarantees that existence is nothing in the world. This cannot be swallowed by Mullā Sadrā whose own view is that existence is real. The third account, however, can evade the argument, insofar as existence is not a property of essence. But it should be noted that the third account is based on Mullasadra’s own view on the reality of existence and the primacy of existence to essence. 5. Concluding remarks If the arguments rendered above are sound, we reach to a criterion in order to interpret Mullā Sadrā’s view on the relationship between existence and essence: his thesis that existence is real is more fundamental than his explanation for the problem of essence’s being existence.

We define and study a new restricted consistency notion RCon ∗ for bounded arithmetic theories T 2 j . It is the strongest ∀ Π 1 b -statement over S 2 1 provable in T 2 j , similar to Con in Krajíček and Pudlák, 29) or RCon in Krajı́ček and Takeuti 107). The advantage of our notion over the others is that RCon ∗ can directly be used to construct models of T 2 j . We apply this by (...) proving preservation theorems for theories of bounded arithmetic of the following well-known kind: The ∀ Π 1 b -separation of bounded arithmetic theories S 2 i from T 2 j is equivalent to the existence of a model of S 2 i which does not have a Δ 0 b -elementary extension to a model of T 2 j . More specific, let M ⊨ Ω 1 nst denote that there is a nonstandard element c in M such that the function n ↦ 2 log c is total in M . Let BLΣ 1 b be the bounded collection schema for Σ 1 b -formulas. We obtain the following preservation results: the ∀ Π 1 b -separation of S 2 i from T 2 j is equivalent to the existence of 1. a model of S 2 i +Ω 1 nst which is 1 b -closed w.r.t. T 2 j , 2. a countable model of S 2 i + BLΣ 1 b without weak end extensions to models of T 2 j. (shrink)

The very existence of explicit techno-scientific controversies in the “nano” arena is often denied on behalf of a conception of science, risks, public engagement and responsibility which borders on a disembodied idealism and merits at least serious discussion. The recurrence of this view prompted us to clarify our position regarding our common field of research, in order to avoid being trapped in the seemingly clear divide between the universal and neutral pursuit of pure science, on the one hand, and on (...) the other hand the infinite variety of values and opinions that lead to the horrors throes of pure relativism. We therefore launched an internal trans-disciplinary project, in order to overhaul the premises underpinning both this idealistic standpoint and our own work, and to find a better definition of our approach to the exploration of the real policy implications of NST research initiatives. Indeed, the debates surrounding NST clearly have wider implications for the examination of issues of Science, Technology and Society as a whole. A first step in this clarification process was taken in Paris, at the conference which has now been published in this issue of Foundations of Chemistry. We further develop it in this paper, in the hope that it will contribute to the joint construction of a better nano-future. (shrink)

Physics is not just mathematics. This seems trivial, but poses difficult and interesting questions. In this paper we analyse a particular discrepancy between non-relativistic quantum mechanics and ‘classical’ space and time. We also suggest, but not discuss, the case of the relativistic QM. In this work, we are more concerned with the notion of space and its mathematical representation. The mathematics entails that any two spatially separated objects are necessarily different, which implies that they are discernible —we say that the (...) space is T2, or “Hausdorff”, or yet “separable”. But when enters QM, sometimes the systems need to be taken as completely indistinguishable, so that there is no way to tell which system is which, and this holds even in the case of fermions. But in the NST setting, it seems that we can always give an identity to them by means of their individuation, which seems to be contra the quantum physical situation, where individuation does not entail identity. Here we discuss this topic by considering a case study and conclude that, taking into account the quantum case, that is, when physics enter the discussion, even NST cannot be used to say that the systems do have identity. This case study seems to be relevant for a more detailed discussion on the interplay between physical theories and their underlying mathematics, in a simple way apparently never realized before.

Twenty classes in ten schools with 627 sixth?grade students in five cities in Taiwan participated in this study. The research provides information on the performance differences among written computation, pictorial representation, symbolic representation and number sense. The results of One?way ANOVA analysis indicate that significant difference was found among WCT, PRT, SRT and NST tests, with F=536.327, p=0.000. The a posteriori comparisons show for each pair (WCT vs PRT, WCT vs SRT, WCT vs NST, PRT vs SRT and SRT vs (...) NST) significant difference at the 0.001 level (p=0.000), except for the pair comparison between PRT and NST. This implies that these Taiwanese students were highly skilled in written computation but their written skills were not equally transferred to use of non?computational paths that depended on symbolic representation, pictorial representation and number sense to solve similar problems.

Consistent with Barbey & Sloman (B&S), it is proposed that performance on Bayesian inference tasks is well explained by nested sets theory (NST). However, contrary to those authors' view, it is proposed that NST does better by dispelling with dual-systems assumptions. This article examines why, and sketches out a series of NST's core principles, which were not previously defined.

Background: Both anxiety and depression in family caregivers of advanced cancer patients are common, and they have a negative influence on both the FCs and the patients. Some studies suggested that a variety of interventions could alleviate the psychological symptoms of FCs. However, there is no consensus on much more effective methods for intervention, and relatively high-quality research is blank in psychological problems of these population in China. The validity of mindfulness-based stress reduction and psychological consultation guided by the needs (...) assessment tool in the psychological status of caregivers will be compared in this study to select a more suitable intervention for the FCs of advanced cancer patients in China.Methods and Analysis: A randomized N-of-1 trial would be conducted at the Cancer Hospital, Chinese Academy of Medical Sciences. Fifty eligible FCs of advanced cancer patients will be recruited, and all will receive three cycles of psychological intervention treatment, with each cycle including both of MBSR and psychological consultation guided by the NST. MBSR and psychological consultation guided by the NST will be compared with each other in each cycle, and the intervention sequence will be based on the random number table generated after the informed consent has been completed. Each treatment period is 2 weeks, and the interval between different treatment cycles or treatment periods is 1 week. The self-reported scales are measured at the beginning and end of each treatment period, including the Self-Rating Anxiety Scale, the Self-Rating Depression Scale, Distress Thermometer, Zarit Burden Interview, Chinese version of the Medical Outcomes Study 12-item Short Form, and Family Carer Satisfaction with Palliative Care scale.Dissemination: The protocol of the study was approved by the Institutional Review Board of the Ethical Committee of the Cancer Hospital, Chinese Academic of Medical Science. The results will be published in a peer-reviewed medical journal. The study is registered at Chinese Clinical Trials Registry with the trial registration number chiCTR2000033707. This study employs an innovative methodological approach on the effectiveness of MBSR and psychological consultation guided by the NST for psychological status of FCs of advanced cancer patients. The findings of the study will be helpful to provide high-quality evidence-based medical data for psychological intervention of FCs of advanced cancer patients, and guide clinicians on best quality treatment recommendations.

Non-relativistic quantum mechanics is grounded on ‘classical’ space and time. The mathematical description of these con- cepts entails that any two spatially separated objects are necessarily dif- ferent, which implies that they are discernible — we say that the space is T2, or "Hausdorff". But quantum systems, in the most interesting cases, some- times need to be taken as indiscernible, so that there is no way to tell which system is which, and this holds even in the case of fermions. (...) But in the NST setting, it seems that we can always give an identity to them, which seems to be contra the physical situation. In this paper we discuss this topic for a case study and con- clude that, taking into account the quantum case, that is, when physics enter the discussion, even NST cannot be used to say that the systems do have identity.

In order to ensure that corporations act in socially responsible ways. R. Freeman says that firms should be legally required to act in accordance with the directives of a moral theory which he developed especially for business – a theory which has come to be called "normative stakeholder theory" (NST). I argue that NST fails as a moral theory and that this failure indicates: (1) that we should abandon the quest to develop a special moral theory for use in business, (...) and (2) that we should not attempt to impose the use of any moral theory upon business, but rather should allow corporations to determine their moral responsibilities in any way they see fit.

There have been several conscious efforts made by different stakeholders in the area of nanoscience and nanotechnology to increase the awareness of social and ethical issues (SEI) among its practitioners. But so far, little has been done at the laboratory level to integrate a SEI component into the laboratory orientation schedule of practitioners. Since the laboratory serves as the locus of activities of the scientific community, it is important to introduce SEI there to stimulate thinking and discussion of SEI among (...) practitioners, which would eventually contribute toward the responsible development of this technology. In this article, through an example (at the Cornell NanoScale Science and Technology Facility (CNF), practitioners of which represent a section of the nano researchers’ community in the USA), it is shown how a SEI component can be incorporated into the laboratory orientation schedule of the practitioners from diverse disciplinary and institutional backgrounds. Results show that, at CNF, the practitioners enjoyed the discussion since most of them learned about SEI for the first time in their professional career. At the same time, some of them were also knowledgeable about SEI and contributed to the debates. Moreover, the SEI orientation had significant positive impact on the scientific community enabling them to self-reflect upon their own research and its implications for the wider society. This article also describes the efforts that were undertaken to disseminate this form of SEI orientation to other 13 USA universities within the National Nanotechnology Infrastructure Network (NNIN, one of the biggest networks funded from National Science Foundation for Nanotechnology research, of which CNF is a part). As a result of this effort, most of the NNIN sites have already started or were in the process of integrating a SEI component into their nanofabrication laboratories to make their users aware of SEI, ensuring eventual robust socio-technical integration in the NNIN laboratories. In the future, this form of SEI orientation can also be disseminated to other nanofabrication laboratories in the USA. (shrink)
