Memento Mori
Stoic and Christian practice of contemplating one's mortality.
Memento Mori (Latin: 'remember you must die') is the contemplative practice of holding one's mortality in mind as a guide to right action, present-moment attention, and proportionate concern about transient goods. The phrase has multiple lineages: the Stoic tradition (Marcus Aurelius's Meditations is full of mortality-contemplation passages — 'You could leave life right now. Let that determine what you do and say and think'); the Christian tradition (medieval ars moriendi tradition, monastic practices, the danse macabre iconography, vanitas painting, the seventeenth-century Trappist greeting 'memento mori, frater'); Buddhist traditions of corpse meditation (maraṇasati) and impermanence contemplation (anicca) parallel the Western practices in distinct philosophical context. Roman tradition tells of triumphant generals being accompanied by a slave whispering 'memento mori' to prevent hubris (probably apocryphal but illustrative). The practice's psychological function is to destabilize the false sense of indefinite future that makes us misallocate attention and concern, restore proportion to everyday concerns by contrast with what is genuinely at stake, and produce gratitude for present existence. Contemporary practical-philosophy revival (Ryan Holiday's bestselling memento mori products and books, the broader Stoicism revival) has substantially popularized the term, with mixed results — the contemplative depth of the practice in monastic and Stoic contexts is often flattened into self-help slogans.

Common criticisms
- Contemporary self-help popularization (especially Ryan Holiday's commercialization with memento mori medallions, calendars, and books) has substantially flattened the contemplative depth of the practice in monastic and Stoic contexts into instagrammable slogans
- can become morbid preoccupation rather than productive contemplation when not held within a broader spiritual or philosophical framework
- the practice presupposes sufficient psychological stability to hold mortality in mind without destabilization — for clinically depressed or grieving individuals it may be contraindicated
- cultural variation in how mortality is integrated into everyday life affects fit
- commercial products and branded contemplation aids are sometimes more performative than substantively contemplative
- the historical practice's coupling with ascetic worldviews (Christian rejection of the world, Stoic apatheia) is often elided in modern adoption.
