Textual analysis maps death metaphors in Paul Kalanithi’s medical memoir

A peer-reviewed content analysis of neurosurgeon Paul Kalanithi’s memoir When Breath Becomes Air identified 211 death-related metaphors and organized them into five broad frames and 10 subordinate types. Led by researchers at the University of Sharjah and published in the journal Language and Health, the study examined how Kalanithi represented death after being diagnosed with stage IV lung cancer at age 36. Movement or transition was the most prominent frame, followed by death as a negative presence, an overwhelming or obscuring force, a concluding performance and a biomedical breakdown. The findings indicate that his language joined a physician’s clinical knowledge with the vulnerability, personal reflection and existential meaning-making of a terminally ill patient. This was a textual analysis of one memoir, not a clinical study, and it did not evaluate cancer treatments or offer clinical guidance.

The researchers treated When Breath Becomes Air as a work of nonfiction that combines medical autobiography, literary narrative and personal reflection. Kalanithi wrote the memoir while confronting terminal cancer; it was published posthumously after his death in 2015 and later became a finalist for the 2017 Pulitzer Prize in Biography. The authors considered the book a particularly rich setting for studying death metaphors because its narrative is voiced by someone whose identities as neurosurgeon and patient overlap. In the analysis, death-related language reflects not only professional knowledge of illness but also Kalanithi’s personal understanding of bodily decline as he faced his own mortality. The central aim was to determine how metaphor structured his representations of death within the distinctive discourse of a medical memoir.

To identify metaphorical expressions, the team used the Metaphor Identification Procedure Vrije Universiteit, commonly known as MIPVU, a recognized method for detecting metaphorical language in texts. The procedure produced 211 instances of death discourse, which the researchers classified into five major metaphor frames and 10 subordinate metaphor types. The principal frame treated death as transition or movement, while the remaining frames presented it as a negative presence, an overwhelming or obscuring force, a concluding performance and a biomedical breakdown. The researchers also examined the distribution and contextual functions of these expressions within the memoir. Because the corpus consisted of a single autobiographical work, the analysis characterizes the conceptual organization of that text rather than demonstrating that the same patterns apply to other patients, writers or people approaching death.

Departure metaphors were among the study’s most prominent examples. In these passages, dying is represented as leaving the world, moving away or passing from one state of existence to another. In an exchange with his wife, Lucy Kalanithi, who was beside him in bed, Kalanithi was asked what frightened or saddened him most. His answer was “Leaving you.” The authors argue that departure metaphors convert death into a relational event in which the dying person leaves while loved ones remain. In this construction, the cultural work of the metaphor is to give biological death a narrative form involving separation, memory and continuing influence. The analysis therefore treats these expressions as more than ornamental figures of speech: they organize the memoir’s presentation of dying around relationships between the person leaving and those who remain behind.

Other passages map death onto the end of a journey, forming what the researchers describe as an alternative conceptualization of mortality. Kalanithi wrote that before his cancer diagnosis he knew “someday I would die, but I didn’t know when.” Afterward, he said, he knew exactly when: “when I had run out of life to give.” The study also examines his comparison of his medical career and struggle with illness to a runner nearing the end of a race, including the image of “a runner crossing the finish line only to collapse.” Together, the journey and finish-line metaphors place death at the end of a course that has already been underway. They give the narrative a temporal structure, linking the changing body and the course of a life to a defined endpoint while retaining the language of effort and movement.

The researchers also found a metaphorical change in agency associated with Kalanithi’s transition from physician to patient. He described having “traversed the line from doctor to patient, from actor to acted upon, from subject to direct object.” The parallel contrasts a physician directing events with a patient increasingly controlled by illness, making the loss of agency part of the memoir’s conceptual portrayal of terminal disease. Kalanithi also resisted the idea that cancer had already ended his life by writing, “This is not the end… Or even the beginning of the end. This is just the end of the beginning.” His comparison of life to “a candle in the wind” expressed an uncertain interval in which the life wavered without a known moment of extinction. Together, these expressions connect his changing position within medicine to the uncertainty and reduced control associated with illness.

Death is not represented only as a force over which Kalanithi has no power. The analysis identified imagery resembling the Grim Reaper, which presents death as a silent force approaching and ultimately claiming a life. At the same time, Kalanithi wrote that the “curse of cancer created a strange and strained existence” while insisting that he was “neither blind to, nor bound by, death’s approach.” The coexistence of these positions is central to the authors’ interpretation. Instead of showing a single progression toward passive acceptance, the memoir repeatedly moves between recognition of death’s approach and a refusal to let it determine the life that remains. The authors place this alternation within the wider structure of medical autobiography, where clinical expertise, patient vulnerability, literary reflection and existential meaning-making continually reshape one another.

The investigators also connect the memoir’s figurative language to what they call coenesthetic metaphorical mappings: figurative constructions that shape experience of mortality and frame responses to death, mortuary practices and ideas about death itself. The study’s central contribution, they say, is not simply a list of labels for individual expressions. It is a demonstration that documented death metaphors are reorganized within the specific discourse of a medical memoir. In When Breath Becomes Air, metaphors arise from both Kalanithi’s expertise as a neurosurgeon and his personal understanding of bodily decline. The authors argue that illness discourse blends medical language with personal and existential language, modifying conventional death metaphors in the process. The findings consequently sit within medical humanities, narrative medicine and existential inquiry, fields in which language and meaning-making are treated as significant features of accounts of illness.

Across the memoir, the identified frames give death different narrative forms. Movement and departure make it a transition and an act of leaving; the journey and runner images place it at the end of an ongoing course; the doctor-to-patient contrast depicts diminished agency; the Grim Reaper imagery presents it as an approaching force; and the biomedical frame associates it with bodily breakdown. The authors describe their work as what appears to be the first systematic discursive exploration of death metaphors in When Breath Becomes Air. Their conclusion is deliberately interpretive: the study maps the language Kalanithi used as a neurosurgeon confronting terminal cancer and shows how that language combined medical knowledge with personal reflection. It offers no evidence that metaphorical framing changes treatment decisions, clinical outcomes or the course of terminal illness. Instead, it provides a focused account of how one medical memoir organized its depictions of mortality through movement, separation, agency, presence, performance and biological collapse.
