Posthumanism vs Transhumanism: What Is the Difference?

Two terms have received attention regarding futuristic ideas and technology: posthumanism and transhumanism. Both argue we might overcome certain technological limits but have different visions for what that future looks like. Posthumanism is a philosophical outlook that challenges conventional ideas about what it means to be human. Transhumanism, on the other hand, focuses on how we could use technology to boost our abilities. Understanding these differences could help you imagine what life might be like in the future. So, what exactly are posthumanism and transhumanism?

Posthumanism is a philosophical concept that challenges the traditional understanding of human nature and existence. It suggests that our evolution might not be limited to biological boundaries but could extend into technology, cultural changes, and scientific advances.

It is an interdisciplinary movement that includes thinkers from fields such as philosophy, literature, music, and science.

One key idea behind posthumanism is that humans are not fixed entities with some kind of inner essence or core self. Instead, they see them as changing over time thanks to external factors.

For example, the fact that many people now have extensive digital lives means that our experience of technology and multimedia has already changed us.

Another aspect of posthumanist thought argues that humans may no longer be alone in terms of their intelligence. Influential transhumanist thinker Ray Kurzweil has suggested that superintelligent machines will emerge, initially having cognitive abilities beyond those of people themselves.

Furthermore, posthumanism prompts moral queries about advancing human capabilities using technology. Is it morally right, it asks, to change our biology or meld ourselves with machinery for the sake of enhancement?

In this way, the term raises discussions around topics such as gene editing, biohacking, and artificial intelligence.

Origins of Posthumanism

The roots of posthumanism are complex and can be traced back centuries to various philosophical and intellectual movements. One early precursor was existentialism, an influential 20th-century school of thought that challenged traditional notions of human identity and existence.

Existentialist thinkers such as Friedrich Nietzsche and Jean-Paul Sartre critiqued ideas like a fixed human essence or nature, emphasizing individual freedom and self-creation instead.

Posthumanism has been influenced by technological developments, including cybernetics, which began to take shape in the mid-20th century. Cybernetics explored how humans interact with machines and information systems, aspects of which can be seen today in transhumanist thinking.

Important contributions also came from French philosophers Gilles Deleuze and Félix Guattari, who introduced their concept of “becoming-animal” in A Thousand Plateaus (1980).

They advanced the view that human identity is not solely defined by biology but is produced through relationships with other entities—blurring the boundaries between humans, animals, and machines.

Science fiction writers have also done much to popularize posthumanist ideas, whether Isaac Asimov’s novels about robots or William Gibson’s books on powerful artificial intelligence. The genre has long imaginatively entertained science-based visions where people blend seamlessly with technology or evolve into something else entirely.

Only during the 1990s did the term posthumanism gain currency, thanks to scholars such as Donna Haraway and Katherine Hayles.

Haraway’s essay A Cyborg Manifesto (1985) argued for a feminist interpretation of cyborgs: they could be seen as symbols capable of both hybridity (the blending inherent in melding bodies with machines) while at once resistance against conventional gender norms.

Hayles examined how our subjectivity changed through technology. She explored the then-new internet, where we moved not just our fingers but our thoughts. Her book How We Became Posthuman (1999) argued for a new understanding of what it meant to be human and found that in the digital age, we are increasingly defined by our relationships with machines.

Posthumanism introduces several defining features that distinguish it from conventional humanist perspectives, addressing varied and far-reaching philosophical, cultural, and ethical concerns.

For starters, posthumanism rejects the notion of a fixed human essence or identity underpinning traditional humanism. It challenges the idea that humans are defined solely by their biological makeup and explores ways to transcend these limitations through technology or cultural change.

Secondly, posthumanism recognizes the interconnectedness and interdependence not just between humans but also between humans and animals, machines, or ecosystems. In other words, being alive involves more than just being human.

Thirdly is what might be called the techy bit. Posthumanists are interested in how technology shapes our experience of being in the world and who we are as individuals—even suggesting it will be central to our future evolution as a species. Some call for “transhuman” technologies that could boost cognitive ability or physical function.

Another feature is ethics: asking whether certain technological interventions on humanity would be moral. Examples include bodily autonomy, social justice considerations about access to new technologies, and environmental sustainability, given some emerging tech’s impacts on ecosystems.

The overall effect of these four features is that posthumanism prompts us to interrogate what we mean by “being human” at this particular moment in time when our relationship with technology has altered so dramatically—while reminding us (as if it were necessary) of how closely connected all living things on Earth already are.

The Concept of Transhumanism

Transhumanism is a philosophy using advanced technologies to surpass human limitations and bolster human faculties.

The movement draws on advances in genetic engineering, neuroscience, cyborg technology, and artificial intelligence (AI) to help humans develop stronger intellectual, physical, and psychological capacities.

A major focus is life extension. Its adherents hope to eliminate aging altogether through therapies that can slow down or reverse the process. Scientists are studying interventions such as telomere lengthening or regenerative medicine.

Cognitive enhancement also features prominently. Brain-computer interfaces (BCIs), which connect minds directly to machines, could expand many aspects of human intelligence—memory, learning capacity, and overall cognitive performance—and enable humans to merge more seamlessly with AI systems.

Elon Musk’s Neuralink project aims ultimately at implants that would give humanity a symbiotic relationship with AI.

Another example of what transhumanists propose is enhancing physical capabilities beyond natural limits. This might include prosthetic limbs that supply greater strength than those composed solely of flesh and bone.

It might also incorporate exoskeletons designed for military operations or other physically grueling work, which enhance strength and endurance by augmenting rather than replacing biological musculature.

All transhumanists share an optimistic vision for this technologically augmented future: that it will help us realize our full potential as individuals while improving society globally.

The roots of transhumanism can be traced back to various intellectual and cultural movements throughout history. Although the term itself was coined by biologist Julian Huxley in 1957, the underpinnings of transhumanist thinking had been developing for some time.

The concept of eugenics, which emerged in the late 19th and early 20th centuries, has had an important influence on transhumanism.

Eugenicists sought to improve humanity through selective breeding and sterilization, fostering a notion of enhancing human traits. While today widely discredited due to its association with discriminatory practices, it contributed to discussions around human enhancement.

Science fiction literature also played an important role in popularizing transhumanist ideas. Writers such as Arthur C. Clarke and Isaac Asimov envisaged futures where humans merged with technology, transcended biological constraints, or developed superintelligence.

In the late 20th century, thinkers such as FM-2030 (Fereidoun M Esfandiary) began using their writings to popularize transhumanist ideas advocating embracing technology to extend human life and achieve radical personal transformation beyond what might traditionally be considered “human.”

Ray Kurzweil’s book The Singularity Is Near (2005) expanded on these ideas, further arguing that advances in technology would lead to a point at which artificial intelligence surpassed human intelligence—“the singularity,” which would fundamentally transform society.

Overall, there are scientific, philosophical, and literary influences behind how we think about becoming more than simply ourselves: eugenics, technological advances, and visions of future societies depicted by science fiction writers—all fed into what has become collectively known as transhumanism.

As an intellectual and philosophical movement, several key principles distinguish transhumanism from other ideologies. Firstly, it favors the use of advanced technologies to enhance human capabilities.

The idea is that technological progress could make it possible to transcend biological limitations on physical, intellectual, and psychological performance—including aging. Transhumanists believe this should be a matter of personal choice rather than something decided by nature.

Secondly, transhumanism is future-oriented. It imagines scenarios in which humans overcome their current biological constraints through advances in science and technology. Life extension, cognitive enhancement, and the integration of machines with people are some themes beloved by those who believe in this worldview.

Thirdly, there’s an emphasis on having evidence for claims made: rationality, as opposed to dogma or faith-based reasoning, is valued here.

Empirical research should be at the core of any suggestions about how humans might improve themselves using technology. Scientists working alongside philosophers (and others) can help society navigate this complex area successfully.

Fourthly, individual autonomy matters. What follows from that will be familiar if you have followed debates around reproductive rights.

Just as a woman has control over her own body (or ought to), so does she have dominion over her mind if certain enhancements become available—unless those systems start making autonomous decisions for us.

Finally, ethical matters are an integral part of transhumanist conversation. Such dialogue usually covers fairness regarding access to enhancements, the possible impacts on social structures from more intelligence or artificial superintelligence, and how to address perils linked to accidental outcomes or misuse.

Posthumanism and transhumanism are two movements that share an interest in human enhancement through technology but differ greatly.

Posthumanism is a philosophical movement that challenges traditional ideas of what it means to be human. It asks whether the boundaries of the “human” can be transcended and whether there might even be something about humanity that makes it unfit for survival.

Posthumanists argue we need a broader conception of what counts as being human if we are going to understand how our species relates to other entities—both technological and ecological—with which we share our world.

Transhumanism, by contrast, is more practical: While it shares some concerns with posthumanism, its main focus is on using advanced technologies—such as genetic engineering or artificial intelligence (AI)—to enhance human intellectual and physical abilities beyond what’s possible naturally.

Transhumanist thought posits a future where humans merge with machines not just for curiosity’s sake but because doing so will enable them to live longer, perform better, and maybe even achieve superintelligence.

In short, both movements sometimes get lumped together because they collectively ask us to consider futures beyond simply “more people” or “better healthcare.”

However, their ideological groundings diverge significantly when you look closer. One seeks a radical overhaul of everything we take for granted about ourselves; the other mostly wants everyone to have wings.

What sets these two ideologies apart is their underlying philosophy—posthumanism questions the idea of a fixed human essence, while transhumanism is open to using technology to enhance our abilities.

It’s about deciding whether you want a wholesale reimagining of humanity’s relationship with the world or just some practical applications for self-improvement through tech.
