In 2004, the journal Diogenes devoted its Issue 208 to “Myths and Gender”, predominantly focused on the figures incarnating the in-between, from the androgyne to the third sex. The current issue represents an extension of this theme, but, if its title recalls the term “gender” - the choice of English translating the strangeness to which it seems condemned in France - it is to enunciate it less in relation to myths than to the theoretical mode.
