Feeling What We Never Lived: Prosthesis and Prosthetic Memory
The term prosthesis is derived from the Greek pros-tithenai, which translates to “to add to” or “to place onto.” The Oxford English Dictionary states that it initially emerged in medical literature to indicate the substitution of an absent limb or body part. Over time, it has come to describe any external enhancement that boosts or broadens human ability, eyewear that improves sight, instruments that extend reach, or even language as a replacement for experience. This root idea of adding on is what makes prosthesis such a useful concept in media theory. If every medium functions as an extension of human senses, then all media are, in some sense, prosthetic. When we move from mechanical prostheses to cinematic or digital ones, the “added” component becomes experiential: media allow us to feel or remember things beyond our direct lives.
In Alison Landsberg’s concept of prosthetic memory, introduced in Prosthetic Memory: The Transformation of American Remembrance in the Age of Mass Culture (2004), the prosthesis moves from the physical to the psychological and emotional. Landsberg argues that modern media, particularly film, enable viewers to “experience” memories that they never personally lived. Watching Schindler’s List, for example, can give a viewer an embodied sense of what it might have felt like to live through the Holocaust, even though they were not there. These memories, she writes, are not “false” or “fake” but real emotional impressions formed through mediation. They become part of who we are, influencing our ethics, identities, and sense of history. In Landsberg’s view, mass culture produces empathy through these prosthetic experiences, allowing memory to become collective and connective rather than private and individual.
Landsberg’s version of prosthesis isn’t the only one. Earlier theorists such as Bernard Stiegler and Friedrich Kittler have also used the term to describe the relationship between humans and technology. Stiegler, in Technics and Time (1998), argues that all technology is prosthetic because human life has always depended on externalizing memory and knowledge. Tools, writing systems, and media are all “memory supports” that make culture possible. For him, prosthesis is not a supplement added to an already-complete human, it is what makes the human possible in the first place. Kittler, meanwhile, focuses on machines themselves. In Gramophone, Film, Typewriter (1999), he describes these devices as prostheses of perception and memory: they record, store, and reproduce sounds and images that human senses cannot retain. Where Stiegler emphasizes philosophical dependence, Kittler highlights technological replacement. Both show how the human body and mind rely on external systems of recording and mediation.
Compared to these more technical perspectives, Landsberg’s “prosthetic memory” centers the emotional and ethical. While Kittler and Stiegler see prostheses as tools that store memory, Landsberg sees media as creating new memories. Her version of prosthesis works on the level of empathy, not machinery. It bridges affect and technology, showing that cultural memory is mediated not just by devices but by feelings that circulate through them. In this way, Landsberg extends Stiegler’s argument about externalized memory into the realm of shared experience and social consciousness.
For students of media theory, this term is valuable because it reframes what media actually do. Rather than treating media as neutral channels that transmit information, the concept of prosthesis reminds us that every act of mediation changes how we think, feel, and remember. It ties directly to McLuhan’s idea of media as “extensions of man,” but adds a moral dimension: prosthetic media don’t just extend our senses, they extend our capacity for empathy. In an age dominated by screens and simulation, the line between experiencing something and remembering it becomes blurred. Prosthetic memory makes that blurring visible.
A clear example of this can be seen in contemporary digital culture. Virtual-reality projects like the Holocaust Memorial VR experience or immersive museum exhibits allow participants to step into other people’s histories. Even short-form platforms such as TikTok produce similar effects when users encounter raw, emotional content about war, displacement, or injustice. Viewers may never have lived these events, yet they “remember” them through the intensity of mediated experience. This exemplifies prosthetic memory at work, a technological extension of emotion that influences how individuals perceive global occurrences and their positions within those events. Nevertheless, it also prompts inquiries regarding authenticity and saturation: when empathy is mediated, can it diminish its intensity? Does ingesting excessive prosthetic memories result in compassion fatigue instead of comprehension?
Notwithstanding these conflicts, the concept of prosthesis continues to be a significant metaphor in media theory. It captures how technologies not only extend our bodies but also our minds and emotions. From Stiegler’s technical human, to Kittler’s mechanical memory, to Landsberg’s empathetic imagination, prosthesis maps the evolving relationship between humans and their media. It helps us see that mediation is never passive: each new form of media rewires our ways of knowing and remembering.
Ultimately, thinking about prosthetic memory shows that media theory isn’t just about analyzing devices, it’s about recognizing how those devices shape our inner lives. Media becomes the connective tissue between the individual and the collective, between personal experience and cultural history. They are, quite literally, the prostheses through which we feel what we never lived, and remember what we never saw.
“I realized how often my emotions toward global events are shaped by images I’ve never witnessed firsthand.”
That personal insight would make it feel more dialogical (what Schandorf values).
