Posthumanism or post-humanism (meaning "after humanism" or "beyond humanism") is a term with at least seven definitions according to philosopher Francesca Ferrando:
Philosopher Ted 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 religious 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, "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.
Ihab Hassan, theorist in the academic study of literature, once stated:
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.
