An Experiment with Time

''An Experiment with Time'' is a book by the British soldier, aeronautical engineer and philosopher J. W. Dunne about his precognitive dreams and a theory of time which he later called "Serialism". First published in March 1927, the book was widely read. Although never accepted by mainstream science, it has influenced imaginative literature ever since. Dunne published four sequels: ''The Serial Universe'', ''The New Immortality'', ''Nothing Dies'' and ''Intrusions?''

Description

Overview

''An Experiment with Time'' discusses two main topics.

The first half of the book describes a number of precognitive dreams, most of which Dunne himself had experienced. His key conclusion was that such precognitive visions foresee future personal experiences by the dreamer and not more general events.

The second half develops a theory to try and explain them. Dunne's starting point is the observation that the moment of "now" is not described by science. Contemporary science described physical time as a fourth dimension and Dunne's argument led to an endless sequence of higher dimensions of time to measure our passage through the dimension below. Accompanying each level was a higher level of consciousness. At the end of the chain was a supreme ultimate observer.

According to Dunne, our wakeful attention prevents us from seeing beyond the present moment, whilst when dreaming that attention fades and we gain the ability to recall more of our timeline. This allows fragments of our future to appear in pre-cognitive dreams, mixed in with fragments or memories of our past. Other consequences include the phenomenon known as deja vu and the existence of life after death.Priestley (1989)

Dreams and the experiment

Following a discussion of brain function in which Dunne expounds mind-brain parallelism and highlights the problem of subjective experience, he gives anecdotal accounts of precognitive dreams which, for the most part, he himself had experienced.

The first he records occurred in 1898, in which he dreamed of his watch stopping at an exact time before waking up and finding that it had in fact done so. Later dreams appeared to foretell several major disasters; a volcanic eruption in Martinique, a factory fire in Paris, and the derailing of the Flying Scotsman express train from the embankment approaching the Forth Railway Bridge in Scotland.

Dunne tells how he sought to make sense of these dreams, coming slowly to the conclusion that they foresaw events from his own future, such as reading a newspaper account of a disaster rather than foreseeing the disaster itself. In order to try and prove this to his satisfaction, he developed the experiment which gives the book its title. He kept a notepad by his bedside and wrote down details of any dreams immediately on waking, then later went back and compared them to subsequent events in his life. He also persuaded some friends to try the same experiment, as well as experimenting on himself with waking reveries approaching a hypnagogic state.

Based on the results, he claimed that they demonstrated that such precognitive fragments were common in dreams, even that they were mixed up in equal occurrence with past memories, and therefore they were difficult to identify until after the event they foresaw. He believed that the dreaming mind was not drawn wholly to the present, as it was during wakefulness, but was able to perceive events in its past and future with equal facility.

The theory of Serialism

Having presented Dunne's evidence for precognition, the book moves on to a possible theory in explanation which he called Serialism.

The theory harks back to an experience with his nurse when he was nine years old. Already thinking about the problem, the boy asked her if Time was the moments like yesterday, today and tomorrow, or was it the travelling between them that we experience as the present moment? Any answer was beyond her, but the observation formed the basis of Serialism.

Within the fixed spacetime landscape described by the recently published theory of general relativity, an observer travels along a timeline running in the direction of physical time, ''t''₁. Quantum mechanics was also a newly emerging science, though in a less-developed state. Neither relativity nor quantum mechanics offered any explanation of the observer's place in spacetime, but both required it in order to develop the physical theory around it. The philosophical problems raised by this lack of rigorous foundation were already beginning to be recognised.

The theory resolves the issue by proposing a higher dimension of Time, ''t''₂, in which our consciousness experiences its travelling along the timeline in ''t''₁. The physical brain itself inhabits only ''t''₁, requiring a second level of mind to inhabit ''t''₂ and it is at this level that the observer experiences consciousness.

However, Dunne found that his logic led to a similar difficulty with ''t''₂ in that the passage between successive events in ''t''₂ was not included in the model. This led to an even higher ''t''₃ in which a third-level observer could experience not just the mass of events in ''t''₂ but the ''passage'' of those experiences in ''t''₂, and so on in the infinite regress of time dimensions and observers which gives the theory its name.

Dunne suggested that when we die, it is only our physical selves in ''t''₁ who die and that our higher selves are outside of mundane time. Our conscious selves therefore have no mechanism to die in the same kind of way and are effectively immortal. At the end of the chain he proposed a "superlative general observer, the fount of all ... consciousness".

Publishing history

''An Experiment with Time'' was first published by A & C Black in March 1927. Dunne continued to update it and many new editions and impressions were published over his lifetime. After Black had brought out the second edition, Dunne changed publisher to Faber & Faber, with whom he would remain. The third edition incorporated major new material and was published by Faber's in 1932; this and subsequent editions were published in the US by Macmillan. The final version which he had a hand in was published as a "reprint" in 1948.

Faber continued printing paperback editions until at least 1973, and others have appeared since.

Reception

Academic

Initial reactions from the scientific and scientifically-minded community were broadly positive. ''Nature'' carried a review by Hyman Levy. They accepted that Dunne was a sober and rational investigator who was doing his best to take a scientific approach. They acknowledged that if his ideas about time and consciousness were true then his book would be truly revolutionary.Jones (2020) However opinions differed over the existence of dream precognition, while his infinite regress was almost universally judged to be logically flawed and incorrect.

Philosophers who criticised ''An Experiment with Time'' on much the same basis included J. A. Gunn, C. D. Broad and M. F. Cleugh.

Physicist and parapsychologist G. N. M. Tyrrell explained:

Mr. J. W. Dunne, in his book, ''An Experiment with Time'', introduces a multidimensional scheme in an attempt to explain precognition and he has further developed this scheme in later publications. But, as Professor Broad has shown, these unlimited dimensions are unnecessary, ... and the true problem of time—the problem of becoming, or the passage of events from future through present to past, is not explained by them but is still left on the author's hands at the end.

Later editions continued to receive attention. In 1981 a new impression of the 1934 (third) edition was published with an introduction by the writer and broadcaster Brian Inglis. The last (1948) edition was reprinted in 1981 with an introduction by the physicist and parapsychologist Russell Targ. A review of it in ''New Scientist'' described it as a "definitive classic".

Mainstream scientific opinion remains that, while Dunne was an entertaining writer, there is no scientific evidence for either dream precognition or more than one time dimension and his arguments do not convince.

Popular

''An Experiment with Time'' became well known and was widely discussed. Not to have read him became a "mark of singularity" in society.

Critical essays on Serialism, both positive and negative, appeared in popular works. Among others, H. G. Wells
