It is common today in public discussion, whether the context is academic, political, or even legal, to take it for granted that using the word "man," in isolation or as a suffix, to refer to all of humanity, or using the pronoun "he" where any person, male or female, may be referred to, is to engage in "sexist language," i.e. language that embodies, affirms, or reinforces discrimination against women or the patriarchal subordination of women to men. Not everyone agrees with this view, and "he" and "man" often seem to creep inappropriately into the speech of even those who consider themselves above such transgressions; but the ideology that there is "sexist language" in ordinary words and in the ordinary use of English gender rarely comes under sustained criticism, even in the intellectual arenas where all things are supposed to be open to free inquiry. Instead, the inquiry is usually strongly inhibited by quick charges of "sexism" and by the other intimidating tactics of political correctness. Such defensiveness accompanies the widely held conviction that the theory of "sexist language" and the program to institute "gender neutral" language are absolutely fundamental to the social and political project of feminism. The theory of "sexist language," however, is no credit to feminism, for it is deeply flawed both in its understanding of the nature of language and in its understanding of how languages change over time. Since the ideology that there is "sexist language" seeks, indeed, to change linguistic usage as part of the attempt to change society and forms of thought, the latter is particularly significant.
