How we talk about misogyny and sexual violence in literary texts matters—to our students, to our colleagues, and to the future of the humanities and of higher education—and the “Me Too” movement has revived with new urgency debates about how to do that. In this essay, I explore the ethical implications of invoking the “Me Too” movement in the classroom, and I offer a model for designing a course that does not simply present women’s narratives as objects of study but rather uses those narratives to give students opportunities and tools to participate in the “Me Too” movement themselves. To re-think eighteenth-century women’s writing in light of “Me Too,” I contend, is to participate in the movement, and so in our teaching we must engage with the ethics of the movement as well as the subject matter.

The use of archimetaphor as an evaluative device of persuasion in the genre of journalistic commentaryThe present study explores the cognitive use of archimetaphor belonging to the evaluative devices of persuasion in emotional argumentation. The corpus consists of forty editorials taken from the Internet French newspapers and magazines. The subject matter of the gathered texts includes two thematic groups of reforms concerning the higher education system and the special retirement plan for public sector employees. Thanks to the archimetaphor the addresser may highlight or hide chosen aspects of the described problem in order to activate vital values concerning our life and existence. Therefore, the concept of “conflict” described in the analysed textes is conceptualised by means of four natural forces (elements) such as fire, air (wind), water and earth (soil) which leads both to the mechanism of naturalisation and axiological polarisation of the presented reality. The mechanism itself stems from two opposing relations: identification and differentiation, allowing the grouping of presented facts to the class of US (protagonists) and THEM (antagonists). In consequence, such axiological persuasion aims at influencing the addressees’ will and decisions and allows for nearly absolute acceptance of the opinions presented by the addresser. Użycie archimetafory jako perswazyjnego środka wartościującego w dziennikarskim gatunku komentarzaCelem niniejszego artykułu jest analiza kognitywnego użycia archimetafory, należącej do perswazyjnych środków służących wartościowaniu w argumentacji emocjonalnej. Korpus składa się z czterdziestu artykułów wstępnych zaczerpniętych ze stron internetowych francuskich magazynów i czasopism. Problematyka zebranych tekstów dotyczy dwóch tematycznych grup opisujących reformę szkolnictwa wyższego oraz specjalnego systemu emerytalnego dla pracowników sektora publicznego. Dzięki archimetaforyzacji nadawca może odpowiednio uwypuklić lub ukryć wybrane aspekty opisywanego zagadnienia w celu aktywowania wartości witalnych związanych z naszym życiem i egzystencją. To właśnie dlatego konceptualizacja pojęcia „konfliktu” poruszanego w analizowanym materiale odnosi się do czterech sił natury (żywiołów), takich jak: ogień, powietrze (wiatr), woda i ziemia (gleba), co z kolei prowadzi do naturalizowania i aksjologicznej polaryzacji opisywanej rzeczywistości. Mechanizm ów opiera się na dwóch typach relacji: identyfikacji i dyferencjacji (odmienności), pozwalających na pogrupowanie prezentowanych faktów do klasy MY (protagoniści) i ONI (antagoniści). Taka aksjologiczna perswazja ma za zadanie wpływać na wolę i decyzje odbiorcy, co skutkuje niemal bezwarunkową akceptacją prezentowanych przez nadawcę poglądów.
