The Reification of Time

Bergson distinguished between two fundamentally different temporal experiences that we conflate in both philosophy and daily life.
Clock Time (temps) is the time of measurement, the time of schedules and calendars. It consists of discrete, equivalent units that can be counted, divided, and arranged. Clock time treats temporal moments as if they were spatial points on a line, homogeneous, interchangeable, and external to consciousness.
This is the time that enables coordination, scientific measurement, and industrial organization. It's extraordinarily useful for certain purposes. But it's not time as we actually experience it.
Duration (durée) is lived time, the time of experience itself. Duration is qualitative rather than quantitative, heterogeneous rather than homogeneous, and indivisible rather than discrete.
Bergson's favorite illustration: listening to a melody. Each note gains meaning only in relationship to what came before and what is anticipated to come after. You can't experience a melody as a series of discrete moments, you experience it as a flowing whole where past, present, and anticipated future interpenetrate each other continuously.
Duration cannot be measured because the very act of measurement transforms flowing experience into static spatial units. When you try to capture lived time in clock divisions, you're not measuring time, you're replacing temporal experience with spatial representation.
Bergson proposed a thought experiment that reveals the difference between clock time and lived duration:
Imagine that all physical processes on Earth suddenly doubled in speed. Days became twelve hours. Heartbeats doubled. All movements accelerated proportionally.
Scientific instruments would detect no difference because all relationships remain proportional. The ratio between Earth's rotation and your heartbeat stays constant. From a physics perspective, nothing has changed.
Yet for conscious beings, the experience would be profoundly different. The thickness of a day, the rhythm of conversation, the unfolding of thought, all fundamentally altered.
This reveals that lived time has qualities that mechanical measurement cannot capture. Clock time is a useful abstraction, but it's not the reality of temporal experience.
The treatment of time as an object isn't natural or inevitable, it emerged historically through specific cultural and technological developments.
Medieval life organized itself around what historian Jacques Le Goff calls "Church time," the rhythm of prayers, seasons, and religious observances that honored natural and spiritual cycles rather than mechanical precision.
The shift toward objectified time accelerated with mechanical clocks in the late medieval period and reached a culmination in industrial capitalism. E.P.
Thompson's research shows how factory discipline required workers to internalize "clock time" rather than "task time," to work according to measured hours rather than natural rhythms or the completion of meaningful work.
This wasn't just a practical adjustment. It was a philosophical transformation that changed how humans conceptualize existence itself.
We began treating time as:
Divisible (into hours, minutes, seconds)
Measurable (by external instruments)
Commodifiable (wages paid by the hour)
Exchangeable (one hour equals another)
Scarce (never enough of it)
External (something we exist within rather than as)
None of these properties describe lived temporal experience. They describe clock time, a social construction that proved economically useful but philosophically misleading.
When productivity apps treat time as divisible, measurable blocks to be filled with activities, they embody the reification Bergson critiqued. They take lived temporal experience and reduce it to spatial representation.
The calendar grid literally spatializes time, makes it into rows and columns, blocks and boundaries, containers to be filled. This spatial representation can coordinate meetings but cannot capture or support the flowing, meaningful experience of actually living through a day.
Consider how you actually experience your morning:
You wake with certain energy, certain thoughts, certain feelings about what the day holds. These aren't discrete moments but a continuous flow. The coffee tastes a certain way. The shower has certain sensations. The mental preparation for work or family responsibilities unfolds organically.
None of this fits in calendar blocks. The experience is qualitative, continuous, and context-dependent. It can't be captured by "Morning Routine, 6:00-6:30 AM."
When you reduce morning experience to a 30-minute block, something essential is lost, the lived quality that makes it your morning, the temporal thickness that constitutes actual experience.
