Egg or sperm? The mechanism of sexual fate decision in germ cells has been a long‐standing issue in biology. A recent analysis identified foxl3 as a gene that determines the sexual fate decision of germ cells in the teleost fish, medaka. foxl3/Foxl3 acts in female germline stem cells to repress commitment into male fate (spermatogenesis), indicating that the presence of mitotic germ cells in the female is critical for continuous sexual fate decision of germ cells in medaka gonads. Interestingly, foxl3 (...) is found in most vertebrate genomes except for mammals. This provides the interesting possibility that the sexual fate of germ cells in mammals is determined in a different way compared to foxl3‐possessing vertebrates. Considering the fact that germline stem cells are the cells where foxl3 begins to express and sexual fate decision initiates and mammalian ovary does not have typical germline stem cells, the mechanism in mammals may have been co‐evolved with germline stem cell loss in mammalian ovary.

In this paper, using Mark Schroeder’s (2008a) expressivist semantic framework for normative language as a case study, I will identify difficulties that even an expressivist semantic theory capable of addressing the Frege-Geach problem will encounter in handling the logical possibility of moral dilemmas. To this end, I will draw on a classical puzzle formulated by McConnell (1978) that the logical possibility of moral dilemmas conflicts with some of the prima facie plausible axioms of the standard deontic logic, which include obligation (...) implies permission. On the tentative assumption that proponents of ethical expressivism should be generally committed to securing the logical possibility of moral dilemmas in their semantic theories, I will explore whether and how expressivists can successfully invalidate obligation implies permission within the framework developed by Schroeder. The case study eventually reveals that this can indeed be a hard task for expressivists. Generalizing from the case study, I will suggest that the source of the difficulty ultimately lies in the mentalist assumption of the expressivist semantic project that the logico-semantic relations exhibited by normative sentences should be modeled in terms of the psychological attitudes that speakers express by uttering them. My final goal will be to show that the difficulty expressivists face in dealing with the logical possibility of moral dilemmas is a reflection of the more general problem that their commitment to the mentalist assumption prevents them from flexibly adopting or dropping axioms in their semantic theories to get the right technical results.

U ovom radu, koristeći Mark Schroederov (2008a) semantički okvir za ekspresivistički normativni jezik kao studiju slučaja, identificirat ću poteškoće s kojima će se čak i ekspresivistička semantička teorija sposobna za rješavanje Frege-Geach problema susresti pri objašnjenju logičke mogućnosti moralnih dilema. U tu svrhu, oslonit ću se na klasičnu zagonetku koju je formulirao McConnell (1978)a pokazuje da se logička mogućnost moralnih dilema sukobljava s nekim od naizgled opravdanih aksioma standardne deontičke logike, među kojima je i aksiom da obaveza implicira dopuštenost. Na (...) temelju tentativne pretpostavke da zastupnici etičkog ekspresivizma trebaju općenito biti posvećeni osiguravanju logičke mogućnosti moralnih dilema u svojim semantičkim teorijama, istražit ću da li i kako ekspresivisti mogu uspješno opovrgnuti aksiom da obaveza implicira dopuštenje unutar okvira koji je razvio Schroeder. Studija slučaja konačno otkriva da to može biti zaista težak zadatak za ekspresiviste. Generalizirajući iz studije slučaja, sugerirat ću da izvor poteškoće leži u mentalističkoj pretpostavci ekspresivističkog semantičkog projekta da bi logičko-semantički odnosi prikazani normativnim rečenicama trebali biti modelirani pomoću psiholoških stavova koje govornici izražavaju izgovarajući ih. Moj konačni cilj će biti pokazati da je poteškoća s kojom se ekspresivisti susreću u suočavanju s logičkom mogućnosti moralnih dilema odraz općeg problema da njihova predanost mentalističkoj pretpostavci sprječava fleksibilno usvajanje ili odbacivanje aksioma u njihovim semantičkim teorijama kako bi dobili ispravne tehničke rezultate.

教養と学問が関係することは、実は自明ではない。教養とは何か。また学問と思想はどのように関わるのか。知識人として、学者として、丸山が発し続けた問いと思考の展開を、遺された言葉の総体から精緻に読み解き、「 丸山論」をこえて現代日本に提示。.

Possible worlds have revolutionised philosophy and some related fields. But, in recent years, tools based on possible worlds have been found to be limited in many respects. Impossible worlds have been introduced to overcome these limitations. This Element aims to raise and answer the neglected question of what is characteristically impossible about impossible worlds. The Element sheds new light on the nature of impossible worlds. It also aims to analyse the main features and utility of impossible worlds and examine how (...) impossible worlds can capture distinctions which are unavailable if we limit ourselves to possible world-based tools.

Although numerous disciplines recognize multiple ways of conceptualizing time, Stefan Tanaka argues that scholars still overwhelmingly operate on chronological and linear Newtonian or classical time that emerged during the Enlightenment. This short, approachable book implores the humanities and humanistic social sciences to actively embrace the richness of different times that are evident in non-modern societies and have become common in several scientific fields throughout the twentieth century. Tanaka first offers a history of chronology by showing how the social (...) structures built on clocks and calendars gained material expression. Tanaka then proposes that we can move away from this chronology by considering how contemporary scientific understandings of time might be adapted to reconceive the present and pasts. This opens up a conversation that allows for the possibility of other ways to know about and re-present pasts. A multiplicity of times will help us broaden the historical horizon by embracing the heterogeneity of our lives and world via rethinking the complex interaction between stability, repetition, and change. This history without chronology also allows for incorporating the affordances of digital media. (shrink)

Over the last few years, I have attended several political meetings concerned with the refugee crisis, multiculturalism or Indigenous rights in Australia, meetings at which liberal democratic–minded ‘left-wing’ people came together to discuss, or agitate for change in, governmental policies. At these meetings, I always found it difficult to accept the slogans on their placards and in their speeches: ‘Shame Australia! Reconciliation for a united Australia’, ‘Wake up Australia! We welcome refugees!’ or ‘True Australians are tolerant! Let’s celebrate multicultural Australia!’ (...) My uncomfortable feeling came not only from the fact that I was left out because of my Japanese nationality but also because I had never seen or heard words like ‘shame Japan’, ‘wake up Japan’ or ‘true Japanese are...’ at Japanese ‘left-wing’ political gatherings. In Japan, these are words used only by right-wing nationalists. Indeed it is difficult to even imagine liberal-left intellectuals in postwar Japan calling for a ‘true Japanese’ political response, such is the extent to which the idea of ‘good nationalism’ is now regarded as an oxymoron. This is my starting point for an essay in which I want to be attentive to the different roles played by national in the Japanese and Australian political environments. (shrink)
