The third sex, which for a long period of history meant the androgyne and the homosexual, took on a new sense around 1900, when it was applied to emancipated women, who were featured by novelists and analysed by psychiatrists. Assimilated with lesbians, ‘desexualized’ by their modern way of life, they were labelled ‘neuter’, worker bees in a hive-state where ‘female-male’ markers were tending to disappear. Neither men in sex, nor women in gender (at least according to traditional assumptions), they constituted a new ‘battalion’ which highlighted all the anxieties of the time: the involution of dimorphism, the threat of lack of differentiation and the ‘extinction of the race’. But for those who accepted the label, neuterdom evolved from a pejorative concept into an instrument of a kind of liberation and the strategic means to set up creative space cleared of sexual stigma, until political cooption, aware of the resurgence of a ‘superior species’, changed its meaning and tipped over into the worst sort of excess.
