Dreams

The dream invents nothing new. Sleep does not add a power; it drops an effort, and whatever memory arrives is accepted.

Overview

Edwin E. Slosson, an American trained in chemistry who made his living writing about science, put this lecture into English for a New York weekly, The Independent, which ran it across two issues in October 1913. Bergson went over the translation himself, and B. W. Huebsch brought it out as a small book the following year. Behind it lay a single sitting in a Paris hall: a talk to the Institut psychologique on 26 March 1901, printed within weeks in the institute's own bulletin and again that June in a scientific weekly. What Bergson told the room is that dreaming invents nothing. The materials are present all night and perfectly ordinary: what the eye still registers behind the closed lid, what the ear picks up, what the skin and the organs report. Memory rushes at those scraps and clothes them. He gave the audience his own case — a dream of a political assembly, a crowd chanting, and then waking to a dog barking in the street. The difference from waking life, on this account, is not that the sleeper gains a power but that the sleeper has stopped working. Perceiving while awake is effort: the whole accumulated mass of one's memories brought to converge on a single point until a sound is the right sound and a face the right face. Release that tension and the memories still come, but nothing decides which one arrives, and the sleeper accepts whatever does. Alfred Binet, reviewing it in L'Année psychologique, called it a popular lecture with one original idea in it, which is a fair description.

Key concepts

What does it mean to say the dream invents nothing?

That sleep is subtraction rather than addition. The lecture denies dreaming any special faculty: no material appears in it that was not already there as sensation or as memory. The interesting question therefore stops being where the images come from and becomes what waking life had been doing to keep them out. Everything else follows from that reversal.

What raw material is a dream actually working with?

Ordinary sensation, still arriving all night. Light that the closed eyelid continues to register, a sound from the street, pressure and warmth on the skin, the dull reports of the organs. These scraps are vague enough to be read many different ways, and that vagueness is precisely the opening a memory needs in order to clothe them.

Does Bergson think memory ever really loses anything?

No, and the dream is his evidence. Memories that waking life never calls on are not destroyed but crowded out, held back by the demands of acting in the present. Release that pressure and faces, places and scenes from childhood return unbidden, often ones the dreamer could never have summoned on purpose. The exclusion was practical, not a deletion.

Why is perceiving while awake described as work?

Because recognition is an achievement, not a reception. To hear a sound as that particular sound, the whole accumulated mass of one's memories must be brought to bear and narrowed until one of them fits what is arriving. That convergence is effort, sustained continuously and almost never noticed, and it is exactly the effort that sleep lets go.

Themes of the book

What this book returns to, gathered into themes and ordered by how much of the text each one occupies.

What memory does when effort stops

Where does a dream get its material? The answer removes the mystery and moves the question elsewhere: not what sleep adds, but what waking perception was doing all along.

Nothing new is invented in sleep. The sensations are still arriving, light behind the closed lid, a sound from the street, the reports of skin and organs, and memory rushes at those scraps and clothes them; Bergson's own dream of a chanting assembly resolved on waking into a dog barking outside. What changes is tension. Perceiving awake is work, the whole mass of one's memories made to converge on a point until the right one fits; release that effort and whatever memory arrives is accepted.
