What is posthumanism?
Posthumanism is a family of approaches that questions the idea that the human being is a self-contained, uniquely superior, rational master of the world.
It does not necessarily mean that humanity is ending or that humans should be replaced. Rather, it asks us to reconsider what it means to be human once we recognize that human life is inseparable from
- other animals and living organisms;
- technologies and machines;
- social and ecological relationships;
- language, culture, and institutions; and
- the Earth and its wider systems.
The “post” in posthumanism therefore means beyond human-centered thinking, not necessarily after human beings. The human remains important, but is understood as relational, embodied, technologically entangled, ecologically dependent, and more-than-human in its composition.
Who are some leading posthumanist thinkers?
Donna Haraway
Haraway’s 1985 essay “A Cyborg Manifesto” challenged clear divisions between human and machine, organism and technology, nature and culture. Her cyborg is not simply a technologically enhanced person. It is a symbol of the hybrid character of human existence. Her later work emphasizes multispecies relationships and the need to “make kin” with beings beyond our own species.
N. Katherine Hayles
In How We Became Posthuman (1999), Hayles examines the relationships among bodies, information, consciousness, and machines. She resists the fantasy that the mind is merely information that could be separated from the body and uploaded into a computer. For Hayles, cognition is distributed across conscious and nonconscious processes and across biological organisms, technical systems, and environments. Human beings are embodied participants in larger cognitive assemblages.
Rosi Braidotti
Braidotti develops an affirmative and ethically oriented posthumanism. She argues that the traditional image of “Man”—rational, autonomous, European, male, and supposedly universal—has excluded many human beings as well as animals and the Earth. Her posthumanism seeks forms of solidarity grounded in shared vulnerability, interdependence, and participation in a more-than-human world.
Cary Wolfe
Wolfe’s work connects posthumanism with animal studies and disability studies. He argues that merely extending human rights to selected animals does not go far enough. We must question the assumption that rationality, language, autonomy, or other supposedly human capacities determine whose life matters.
Karen Barad
Drawing on quantum physics, feminist theory, and philosophy, Barad argues that beings do not first exist independently and then enter into relationships. They emerge through what she calls “intra-actions.” Relationships are not secondary additions to already existing things; they help constitute the things themselves.
Francesca Ferrando
Ferrando offers a systematic account of philosophical posthumanism, bringing together critiques of human exceptionalism, anthropocentrism, dualism, and fixed identities. She also carefully distinguishes posthumanism from transhumanism.
Other important figures include Bruno Latour, Jane Bennett, Manuel DeLanda, Timothy Morton, and scholars working in animal studies, ecological humanities, science and technology studies, and new materialism.
How does posthumanism differ from transhumanism?
Transhumanism generally supports using technology to overcome biological limitations. Its aspirations may include longer lifespans, increased intelligence, enhanced bodies, freedom from disease, human-machine integration, and possibly the uploading of minds.
Posthumanism, by contrast, asks whether the supposedly independent human being whom transhumanism seeks to enhance ever existed in the first place. It suggests that we have always been dependent upon other organisms, social relationships, tools, languages, and environments. In this sense, we have never been “merely human.”
The contrast should not be made absolute. Some transhumanists recognize ecological and social interdependence, and some posthumanists welcome
technological enhancement. But their characteristic orientations differ:
Transhumanism seeks to create a better human. Posthumanism asks us to rethink the category of the human itself.
