A fundamental notion in a large part of mathematics is the notion of equicardinality. The language with Hartig quantifier is, roughly speaking, a first-order language in which the notion of equicardinality is expressible. Thus this language, denoted by LI, is in some sense very natural and has in consequence special interest. Properties of LI are studied in many papers. In [BF, Chapter VI] there is a short survey of some known results about LI. We feel that a more extensive exposition (...) of these results is needed. The aim of this paper is to give an overview of the present knowledge about the language LI and list a selection of open problems concerning it. After the Introduction $(\S1)$ , in $\S\S2$ and 3 we give the fundamental results about LI. In $\S4$ the known model-theoretic properties are discussed. The next section is devoted to properties of mathematical theories in LI. In $\S6$ the spectra of sentences of LI are discussed, and $\S7$ is devoted to properties of LI which depend on set-theoretic assumptions. The paper finishes with a list of open problem and an extensive bibliography. The bibliography contains not only papers we refer to but also all papers known to us containing results about the language with Hartig quantifier. Contents. $\S1$ . Introduction. $\S2$ .

This article attempts to clarify an “argument from reason” set forth by C. S. Lewis in his Miracles. While there are various contemporary interpretations of the argument, Lewis intended to expose the “cardinal difficulty of naturalism.” First, this article seeks to clarify both Lewis’s argument and the understanding of naturalism that it presupposes. Second, philosophers of religion—especially, William Hasker and Alvin Plantinga—have significantly contributed to the argument’s contemporary discussion, and so their views are addressed with the intent to show how (...) they differ from Lewis’s contribution. C. S. Lewis’s argument from reason was and is remains to this day philosophically timely and deserving of serious consideration. (shrink)

On nomme ici « un sexe » une manière singulière d’envisager une pratique sexuelle et de s’y engager. Michel Leiris est exemplaire dans sa manière d’exposer une pratique que l’on pourrait qualifier, en usant d’un de ses propres termes de « timoré ». Loin d’être naturelle ou immédiatement exaltante, l’acte sexuel se présente plutôt pour lui comme une épreuve, certes sans violence ni dimension sacrale, mais qui peut néanmoins être comparée, comme l’écriture elle-même, à une sorte de corrida intime.
