Who said manifestos are dead? Some thirty years after the publication of Donna Haraway's illustrious A Cyborg Manifesto (Haraway 1991), fifty years after Valerie Solanas's angry and delightful SCUM Manifesto (Solanas 1967), and 170 years after Karl Marx and Friedrich Engels's influential Communist Manifesto (Marx and Engels 1848), a new manifesto in town in fact bears traces of all these and then some: The Xenofeminist Manifesto. This manifesto, which comes in a gorgeously designed booklet version as well as in a colorful and nostalgic 80s computer-culture website with nerdy hexadecimal page numbers and related Twitter account, is a work from the “xenofeminist” collective Laboria Cuboniks. The name of this collective, whose members are from various parts of the globe, is actually an anagram of “Nicolas Bourbaki,” a largely French collective of mathematicians in the early 1900s who sought to affirm abstraction, rigor, and generalization (Laboria Cuboniks 2014). Together with a firm foot in cyberfeminism and a strong penchant for the abstract and universal by way of the logic of computing against the arguably flawed universal of “nature,” the manifesto also clearly bears the marks of feminist ecocriticism, new materialism, queer theory, and technological accelerationism. The two books under review bring various activisms and insights together in an original way, and do so clearly with an eye toward reviving the cyberfeminist spirit through, among others, ideas from Shulamith Firestone's Dialectics of Sex (Firestone 1970). This pairing certainly had me excited, since, as I argue elsewhere, I am, together with Haraway's original cyborg manifesto, firmly of the opinion that feminisms of all kinds should intervene in and contribute even more radically to contemporary techno-culture and philosophy of technology. This is because clearly, new media and genetic technologies are at present some of the most powerful techniques by which we live and probably will live in the near future, and because these technologies are intimately interwoven with Eurocentric masculinism, heterosexism, militarism, and capitalism (Hoofd 2016, 225, 229).
