This article argues the case for posthuman critical theory within the context of the Anthropocene, as both the convergence of posthumanist and postanthropocentric discourses and their development in a qualitatively new and more complex direction. By adopting a cartographic approach to the posthuman, the article surveys recent scholarly production in the field and argues for the need to rethink subjectivity as a collective assemblage that encompasses human and nonhuman actors, technological mediation, animals, plants, and the planet as a whole. Resting on a monistic ontology drawn from critical Spinozism and Deleuzian vital materialism, the article makes the case for posthuman ethics as the expression of affirmative compositions of transversal, multiple, and collective practices of becoming-posthuman.

What are the parameters that define a posthuman knowing subject, her scientific credibility and ethical accountability? Taking the posthumanities as an emergent field of enquiry based on the convergence of posthumanism and post-anthropocentrism, I argue that posthuman knowledge claims go beyond the critiques of the universalist image of ‘Man’ and of human exceptionalism. The conceptual foundation I envisage for the critical posthumanities is a neo-Spinozist monistic ontology that assumes radical immanence, i.e. the primacy of intelligent and self-organizing matter. This implies that the posthuman knowing subject has to be understood as a relational embodied and embedded, affective and accountable entity and not only as a transcendental consciousness. Two related notions emerge from this claim: firstly, the mind-body continuum – i.e. the embrainment of the body and embodiment of the mind – and secondly, the nature-culture continuum – i.e. ‘naturecultural’ and ‘humanimal’ transversal bonding. The article explores these key conceptual and methodological perspectives and discusses the implications of the critical posthumanities for practices in the contemporary ‘research’ university.

This article revisits Irigaray's theory of sexual difference in the light of more contemporary developments in terms of nomadic becomings and non-unitary subjectivity, especially in Deleuze. It defends the notion of embodied materiality on philosophical grounds, by linking it to the issues of power, access, hegemony and exclusion, which are central to post-structuralism. Through a detailed analysis of the sexual politics of difference feminism, the author argues for a non-reactive redefinition of the feminine as a project of becoming, and connects it firmly to feminist discussions about gender and queer theory.

The COVID-19 pandemic is a man-made disaster, caused by undue interference in the ecological balance and the lives of multiple species. Paradoxically, the contagion has resulted in increased use of technology and digital mediation, as well as enhanced hopes for vaccines and biomedical solutions. It has thereby intensified humans' reliance on the very high-tech economy of cognitive capitalism that caused the problems in the first place. This combination of ambivalent elements in relation to the Fourth Industrial revolution and the Sixth Extinction is the trademark of the posthuman condition. This essay explores this condition further, offering both critical and affirmative propositions for moving forward.

This article deals with sexual difference as a philosophy of subjectivity which, however inspired by poststructuralism, was further developed by feminists. The main features of this philosophy are outlined both in terms of its style and of its vision of woman as subject. The notion of ‘difference’ is analyzed in details, as the central concept that sustains the feminist nomadic philosophy of a subject that is both complex and situated, politically empowered and epistemologically legitimate.
