|Criticism of postmodernism|
- Antihumanism: any theory that is critical of traditional humanism and traditional ideas about humanity and the human condition.
- Cultural posthumanism: a branch of cultural theory critical of the foundational assumptions of Renaissance humanism and its legacy. that examines and questions the historical notions of "human" and "human nature", often challenging typical notions of human subjectivity and embodiment  and strives to move beyond archaic concepts of "human nature" to develop ones which constantly adapt to contemporary technoscientific knowledge.
- Philosophical posthumanism: a philosophical direction which draws on cultural posthumanism, the philosophical strand examines the ethical implications of expanding the circle of moral concern and extending subjectivities beyond the human species 
- Posthuman condition: the deconstruction of the human condition by critical theorists.
- Transhumanism: an ideology and movement which seeks to develop and make available technologies that eliminate aging and greatly enhance human intellectual, physical, and psychological capacities, in order to achieve a "posthuman future".
- AI takeover: A more pessimistic alternative to transhumanism in which humans will not be enhanced, but rather eventually replaced by artificial intelligences. Some philosophers, including Nick Land, promote the view that humans should embrace and accept their eventual demise. This is related to the view of "cosmism" which supports the building of strong artificial intelligence even if it may entail the end of humanity as in their view it "would be a cosmic tragedy if humanity freezes evolution at the puny human level".
- Voluntary Human Extinction, which seeks a "posthuman future" that in this case is a future without humans.
Schatzki  suggests there are two varieties of posthumanism of the philosophical kind:
One, which he calls 'objectivism', tries to counter the overemphasis of the subjective or intersubjective that pervades humanism, and emphasises the role of the nonhuman agents, whether they be animals and plants, or computers or other things.
A second prioritizes practices, especially social practices, over individuals (or individual subjects) which, they say, constitute the individual.
There may be a third kind of posthumanism, propounded by the philosopher Herman Dooyeweerd. Though he did not label it as 'posthumanism', he made an extensive and penetrating immanent critique of Humanism, and then constructed a philosophy that presupposed neither Humanist, nor Scholastic, nor Greek thought but started with a different ground motive. Dooyeweerd prioritized law and meaningfulness as that which enables humanity and all else to exist, behave, live, occur, etc. "Meaning is the being of all that has been created," Dooyeweerd wrote [1955, I, 4], "and the nature even of our selfhood." Both human and nonhuman alike function subject to a common 'law-side', which is diverse, composed of a number of distinct law-spheres or aspects. The temporal being of both human and non-human is multi-aspectual; for example, both plants and humans are bodies, functioning in the biotic aspect, and both computers and humans function in the formative and lingual aspect, but humans function in the aesthetic, juridical, ethical and faith aspects too. The Dooyeweerdian version is able to incorporate and integrate both the objectivist version and the practices version, because it allows nonhuman agents their own subject-functioning in various aspects and places emphasis on aspectual functioning (see his radical notion of subject-object relations).
Emergence of philosophical posthumanism
Humanism may be coming to an end as humanism transforms itself into something one must helplessly call posthumanism.
This view predates most currents of posthumanism which have developed over the late 20th century in somewhat diverse, but complementary, domains of thought and practice. For example, Hassan is a known scholar whose theoretical writings expressly address postmodernity in society. Beyond postmodernist studies, posthumanism has been developed and deployed by various cultural theorists, often in reaction to problematic inherent assumptions within humanistic and enlightenment thought.
Theorists who both complement and contrast Hassan include Michel Foucault, Judith Butler, cyberneticists such as Gregory Bateson, Warren McCullouch, Norbert Weiner, Bruno Latour, Cary Wolfe, Elaine Graham, N. Katherine Hayles, Donna Haraway Peter Sloterdijk, Stefan Lorenz Sorgner, Evan Thompson, Francisco Varela, Humberto Maturana and Douglas Kellner. Among the theorists are philosophers, such as Robert Pepperell, who have written about a "posthuman condition", which is often substituted for the term "posthumanism".
Posthumanism differs from classical humanism by relegating humanity back to one of many natural species, thereby rejecting any claims founded on anthropocentric dominance. According to this claim, humans have no inherent rights to destroy nature or set themselves above it in ethical considerations a priori. Human knowledge is also reduced to a less controlling position, previously seen as the defining aspect of the world. The limitations and fallibility of human intelligence are confessed, even though it does not imply abandoning the rational tradition of humanism.
Proponents of a posthuman discourse, suggest that innovative advancements and emerging technologies have transcended the traditional model of the human, as proposed by Descartes among others associated with philosophy of the Enlightenment period. In contrast to humanism, the discourse of posthumanism seeks to redefine the boundaries surrounding modern philosophical understanding of the human. Posthumanism represents an evolution of thought beyond that of the contemporary social boundaries and is predicated on the seeking of truth within a postmodern context context. In so doing, it rejects previous attempts to establish 'anthropological universals' that are imbued with anthropocentric assumptions.
The philosopher Michel Foucault placed posthumanism within a context that differentiated humanism from enlightenment thought. According to Foucault, the two existed in a state of tension: as humanism sought to establish norms while Enlightenment thought attempted to transcend all that is material, including the boundaries that are constructed by humanistic thought. Drawing on the Enlightenment’s challenges to the boundaries of humanism, posthumanism rejects the various assumptions of human dogmas (anthropological, political, scientific) and take the next step by attempting to change the nature of thought about what it means to be human. This requires not only decentering the human in multiple discourses (evolutionary, ecological, technological) but also examining those discourses to uncover inherent humanistic, anthropocentric, normative notions of humanness and the concept of the human.
Contemporary posthuman discourse
Posthumanistic discourse aims to up spaces to examine what it means to be human and critically question the concept of "the human" in light of current cultural and historical contexts  In her book How We Became Posthuman, N. Katherine Hayles, writes about the struggle between different versions of the posthuman as it continually co-evolves alongside intelligent machines. Such coevolution, according to some strands of the posthuman discourse, allows one to extend their subjective understandings of real experiences beyond the boundaries of embodied existence. According to Hayles view of posthuman, often referred to as technological posthumanism, visual perception and digital representations thus paradoxically become ever more salient. Even as one seeks to extend knowledge by deconstructing perceived boundaries, it is these same boundaries that make knowledge acquisition possible. The use of technology in a contemporary society is thought to complicate this relationship.
Hayles discusses the translation of human bodies into information (as suggested by Hans Moravec) in order illuminate how the boundaries of our embodied reality have been compromised in the current age and how narrow definitions of humanness no longer apply. Because of this, according to Hayles, posthumanism is characterized by a loss of subjectivity based on bodily boundaries. This strand of posthumanism, including the changing notion of subjectivity and the disruption of ideas concerning what it means to be human, is often associated with Donna Haraway’s concept of the cyborg. However, Haraway has distanced herself from posthumanistic discourse due to other theorists’ use of the term to promote utopian views of technological innovation to extend the human biological capacity  (even though these notions would more correctly fall into the realm of transhumanism  ).
While posthumanism is a broad and complex ideology, it has relevant implications today and for the future. It attempts to redefine social structures without inherently humanly or even biological origins, but rather in terms of social and psychological systems where consciousness and communication could potentially exist as unique disembodied entities. Questions subsequently emerge with respect to the current use and the future of technology in shaping human existence emerge, as do new concerns with regards to language, symbolism, subjectivity, phenomenology, ethics and justice.
Some critics have argued that all forms of posthumanism have more in common than their respective proponents realize. Posthumanism is sometimes used as a synonym for an ideology of technology known as "transhumanism" because it affirms the possibility and desirability of achieving a "posthuman future", albeit in purely evolutionary terms. However, posthumanists in the humanities and the arts are critical of transhumanism, in part, because they argue that it incorporates and extends many of the values of Enlightenment humanism and classical liberalism, namely scientism, according to performance philosopher Shannon Bell:
Altruism, mutualism, humanism are the soft and slimy virtues that underpin liberal capitalism. Humanism has always been integrated into discourses of exploitation: colonialism, imperialism, neoimperialism, democracy, and of course, American democratization. One of the serious flaws in transhumanism is the importation of liberal-human values to the biotechno enhancement of the human. Posthumanism has a much stronger critical edge attempting to develop through enactment new understandings of the self and others, essence, consciousness, intelligence, reason, agency, intimacy, life, embodiment, identity and the body.
While many modern leaders of thought are accepting of nature of ideologies described by posthumanism, some are more skeptical of the term. Donna Haraway, the author of A Cyborg Manifesto, has outspokenly rejected the term, though acknowledges a philosophical alignment with posthumanim. Haraway opts instead for the term of companion species, referring to nonhuman entities with which humans coexist.
