While it is no doubt a good pedagogical principle to stress the most convincing proof in the first learning of a philosophic thesis, yet a man with any pretence to philosophic effeciency should certainly have at his beck and call several proofs to do service in various situations. Mr. Brown indicates a few subsidiary proofs in connection with the subject of materialsm, a consideration of grave import in the philosophical world today.

The timliness of an investigation into the phenomena of suggestion today can hardly be over estimated. With each succeeding advance it is being given more importance in advertising, in education, and in heath. The author has made it the subject of his master's thesis. Here we have the kernel of his months of thought. The Editor.

Mr. Brown's paper contains a detailed statement of the industrial situation at the present day, and the part which Scholastic philosophy should naturally take in bettering it. Some of the facts he delineates will come as a surprise to many people; those, for example who expect the workingman to gain redress through the courts will find added interest in this paper.

David Eso and Kay Burns edition of philosopher Leo Ferraris previously unpublished 1973 manuscript brings to light a long forgotten satirical work, which, in an age of fake news, possesses renewed relevance. The editors contextualize The Earth is Flat! for the reader with a scholarly introduction and a humorous Forewarning. Author, Leo Ferrari, draws on his extensive knowledge of classical thought and its key figures to present a history of ideas that is sometimes accurate, sometimes speculative. Speculative or alternative aspects (...) of this history support his Flat Earth theme, as do a number of scientific experiments outlined, which the reader is encouraged to try. He traces the conflict between Globularist and Planoterrestrial beliefs from antiquity to his contemporary moment of the early 1970s, marked by space exploration. Later chapters chart the activities and philosophies of the Flat Earth Society of Canada, including Ferraris experience on the lecture circuit and in media platforms. The authors method is to blur the line between seriousness and humour and to show that intellectual work can also be good fun. He uses the idea of a spinning, spherical planet to symbolically represent the alienating effects of technological modernity. (shrink)

Protection against bacterial and viral pathogens by antibodies has always been thought to end at the cell surface. Once inside the cell, a pathogen was understood to be safe from humoral immunity. However, it has now been found that antibodies can routinely enter cells attached to viral particles and mediate an intracellular immune response. Antibody‐coated virions are detected inside the cell by means of an intracellular antibody receptor, TRIM21, which directs their degradation by recruitment of the ubiquitin‐proteasome system. In this (...) article we assess how this discovery alters our view of the way in which antibodies neutralise viral infection. We also consider the antiviral function of TRIM21 in the context of its other reported roles in immune signalling and autoimmunity. Finally, we discuss the conceptual implications of intracellular antibody immunity and how it alters our view of the discrete separation of extracellular and intracellular environments. (shrink)

The purpose of this paper is threefold. First, I visit the Fogelin–Geach-dispute, criticizeMiller''s interpretation of the Geachian notationN(x:N(fx)) and conclude that Fogelin''s argumentagainst the expressive completeness of the Tractariansystem of logic is unacceptable and that the adoptionof the Geachian notation N(x:fx) would not violate TLP5.32. Second, I prove that a system of quantificationtheory with finite domains and with N as the solefundamental operation is expressively complete. Lastly, I argue that the Tractarian system is apredicate-eliminated many-sorted theory (withoutidentity) with finite domains (...) and with N as the solefundamental operation, and thus is expressivelycomplete.

In the Tractatus Logico‐Philosophicus, Wittgenstein adopts a version of logical atomism. This chapter offers an exposition of the Tractarian version of logical atomism. Wittgenstein argues that the constituents of the end products of complete analysis are simple signs, and that there are necessarily existent objects. The chapter explains Wittgenstein's main argument for the possibility of complete analysis. It comments on three recent interpretations of the substance argument and offers an exposition of the substance argument. According to the Tractatus, propositions show (...) the logical form of reality, which is constituted by the logical forms of states of affairs. The substance argument is a reductio ad absurdum. The reductio is the premise that the world had no substance, which is equivalent to the claim that there were no necessarily existent simple objects. The world has substance constituted by necessarily existent simple objects. (shrink)

In their influential paper “The extended mind”, Andy Clark and David Chalmers argue for the possibility of the extended mind. Based on Clark and Chalmers’s views, Stephen Hetherington argues in his paper “The extended knower” that there are extended knowers, provided epistemic externalism holds. He also uses the argument and its conclusion to criticize Baron Reed’s scepticism in the paper “The long road to skepticism” : 236–262, 2007). In this chapter, I argue that both Hetherington’s notion of the extended knower (...) and his argument are problematic. This is because the conceptual intelligibility of his notion of the extended knower entails the highly counterintuitive consequence that, in some cases, some negative entities would have to be constitutive of the extended knower. I also show that Hetherington’s criticism of Reed’s scepticism is not successful, and that there is no reason to believe that Clark and Chalmers would hold that there is the extended knower in Hetherington’s sense.

The Tractatus contains twodifferent proofs of the Grundgedanke, or thenonreferentiality of logical constants. In thispaper, I explicate the first proof in TLP 5.4s andreconstruct the less explicitly stated second proof. My explication of the first proof shows it to beelegant but based on an invalid inference. In myreconstruction of the second proof, the main argumentis that the sign of a logical constant does not denotebecause it possesses the punctuation-mark-nature. Andit possesses the punctuation-mark-nature because,given the analyticity thesis in TLP 5, one (...) canestablish for everyday language an adequate symbolismwith N as the sole fundamental operation such that itssign is a bar indicating merely the order and scope ofits application.

This paper aims to argue against the resolute reading, and offer a correct way of reading Wittgenstein'sTractatus. According to the resolute reading, nonsense can neither say nor show anything. The Tractatus does not advance any theory of meaning, nor does it adopt the notion of using signs in contravention of logical syntax. Its sentences, except a few constituting the frame, are all nonsensical. Its aim is merely to liberate nonsense utterers from nonsense. I argue that these points are either not (...) distinctive from standard interpretations or incorrect. Instead, the Tractarian elucidations help to shed light on the nature of language and logic, and introduce the correct method in philosophy. Philosophy deals with philosophical utterances and Tractarian elucidations by pointing out that they are nonsensical. By doing this, one is helped to see that what they appear to be saying is shown by significant propositions saying something else. (shrink)
