Thierry de Duve outlines the main features of a critical theory of male, all-too-male sexuation and cross-gender emancipation, drawing on Marcel Gauchets theses on Christianity as an exit from religion, Jacques Lacans algebra of desire, and Geneviève Morels analysis of the law of the mother. Wouldnt it have required more than the translation of the three Christian maxims faith, hope, love into the revolutionary maxims liberté, egalité, fraternité? Is there more to the knot of incarnation, fatherhood, and the cult of Mary than just Christian mysticism? Can the uncertainty of fatherhood become an act of faith that acknowledges a fundamental uncertainty? Come On, Men, One More Effort explores ways out of the dead end of political concepts adopted by the Enlightenment and their continued impact today, since the only possibility seems to be to embrace the religious and reject it at the same time.
