How the Industrial Revolution killed the nap

It did not fall out of fashion. It was scheduled out.

Four weeks, in one line

The nap is a biological need.

So the obvious follow-up: if it is a need, what happened to it?

Not that people stopped wanting it — that a way of organising work made it impossible, and then made it shameful.

Task time and clock time

E. P. Thompson’s account of that shift is the spine of this lecture.

The factory needs everyone at once

  • a machine-paced line only works if the whole shift is present
  • one person resting is not merely unproductive — it is disruptive

A structural fact, not a moral one.

Hold that word. The moral part arrives later.

Segmented sleep

Roger Ekirch’s evidence: pre-industrial Europeans commonly slept in two nighttime blocks, with a waking interval between them.

The consolidated eight-hour night is a recent arrangement.

Not a natural one.

Artificial light

  • cheap lighting pushed bedtime later
  • the start of work did not move with it

The compression had to come out of somewhere.

The moral turn

The part worth the most attention

Three steps

Sleeping in the day moves:

  1. from ordinary
  2. to inefficient
  3. to evidence of bad character

Each step is small. The distance covered is not.

Why it stops being examined

Once it is a character judgement it no longer needs an argument.

An argument can be answered. A judgement about the sleeper is simply held.

That is the point at which nobody checks it again.

Before next week

Find one rule, timetable or notice — from any period, including now — that governs when people are permitted to rest.

Bring it.

Next week sets three cultures against each other. Yours is the fourth.

Tell me nobody took it

We did not lose the nap. It was taken, for reasons that made sense to the people taking it, and the shame attached to it afterwards is what stopped anyone noticing.
