J B Priestly was a writer with a broad scope. He was also a social commentator, playwright, broadcaster and literary critic. Born in Barnsley, he began his working life as a clerk in a wool firm. Writing in the evenings, he found success with articles placed in London newspapers.
He was badly wounded in the first world war, and indeed experienced much at that time that was to haunt him for the rest of his life. Post-war, he gained an officer’s scholarship to Trinity Hall, Cambridge, where he studied literature, and from there he went on to become a well known, and rather well-to-do English man of letters.
Published in 1971, Over the Long High Wall is, as he describes it, a reflection on the nature of life, death and time. Time is where Priestly and I meet, both of us having an interest in the precognitive nature of dreams, a subject it’s easy to lose one’s way with, but to which I find him a sober and sensible guide.
He was a powerful dreamer, occasionally stumbling across things in his dream life that subsequently happened, and could not easily be explained away as coincidence. This is a difficult subject to deal with, since there is no explanation for it, and indeed much scepticism. Readers of a hard, rational bent will understandably reject it out of hand. But when it happens to you, you’re compelled to take an interest, which inevitably leads to questions concerning the nature of time and being, and here we need a steady hand if we are not to fall foul of crack-pottery. Better we acquaint ourselves with the thinking of a no-nonsense, pipe smoking Yorkshireman, like Priestly.
If we can dream ahead of time, it suggests the mind is not as firmly fastened down in space or time, as we suppose. It can wander some way ahead, which begs the question, do we have free will? If we have already dreamed a thing, is it inevitable we shall encounter it? Or, being forewarned, can the future be changed? And if it can, what happened to the version of things we saw? It also begs the question, if the mind is not so firmly coupled to brain function, can some part of it survive beyond bodily death. These are interesting questions, but anyone, particularly a famous person, bringing them into the open, is liable to be attacked by rational sceptics, and pilloried as a fool, or charlatan.

Throughout the book, Priestly describes the world, as constructed by rational sceptics, and goes on at some length to explain why he doesn’t think very much of it. Written in 1971, he could easily be describing the world as it is now. He calls it narrow, and life-shrinking. These sceptics, these zealous debunkers of all speculative forays of the mind, are the architects of the long, high wall of the title. It is a construct, he says, which prevents us from gaining a view of a higher, more noble, more meaningful mode of being.
His interest in the time question placed him within the orbit of the time theorist, J W Dunne, whose book “An Experiment with Time” (1927) was very popular, and indeed, still is. Like Priestly, Dunne had also run into precognitive dreams. Dunne was not what one might call an artistic, literary or dreamy type. He was a former military man, a man of science and engineering. Building on the theories of the mathematician Howard Hinton, and physicists Eddington, and Einstein – very much in vogue at the time – Dunne suggested the dreaming self operated in a so-called “fourth dimension”, one at right angles to our familiar three dimensions of space and linear time.
The fourth dimension allows the dreaming mind a full view of our line in time, while our waking mind is restricted to awareness of a single slice of space-time, this being “now”. But here’s where Dunne is an infuriating character to get a handle on. His book is fascinating up to the point where he goes on to explain his theory of precognitive dreaming, which, though he claims is simple, has me wondering if I have not suffered some sort of brain injury, since my own college days. His later books, intended to further simplify things for a more “popular” audience, I find even more bewildering. Reassuringly for me, Priestly is of a similar view.
He warns us that Dunne provides little service to brevity, no matter how hard he tries, but their friendship helped nurture the plot of several of Priestly’s plays, in which he “played” with the idea of time. “Time and the Conways” and “An Inspector Calls” are perhaps the most famous, though my personal favourite is the strikingly Ouspenskian: “I have been here before” set in a remote inn in the Yorkshire Dales, and archived (along with the others) as MP3 here.
Setting aside the entanglements of theory, the idea of there being a looseness to time opens up the human psyche to a more speculative field of enquiry, one into which the spirit soars, while the rational sciences tend only to shut it down. There is no such thing as precognition they say, there is a single line in time, we live, we die, and there is no point to anything. They create a closed world, in which the seedlings of spirit find only stony ground. Of course, science is correct to build itself up from foundations of solid evidence. But by this same yardstick, spontaneous cases of precognition in dreams must always be dismissed as anecdotal, as mere stories.
Which brings Priestly to the phenomenon of the professional sceptic. This is a person who sets themselves up as investigator and debunker of phenomenal claims. They are not necessarily of the scientific profession, often conjurers and showmen, or psychologists. He calls them the “camp followers” of science, who see it as their role to ruin the reputation of anyone daring to stick their necks above the parapet. And, whilst often the most shrill, their explanations, explaining away things like precognition, can also be the most tortuous and ridiculous, yet, having the “rational” on their side, the tortuous and the ridiculous are, sadly, the only explanations we are allowed to arrive at. Anything else is dismissed as bunk.
Clearly then, Priestly stuck his neck out, but there was more of an appetite for this kind of thing in the early part of the twentieth century than there is now. As for the evidence, or the theoretical expositions, he writes he didn’t much care one way or the other. He deals in greater depth with Dunne, and his own insights into dream precognition, in his longer work “Man and Time” (1964). Over the Long High Wall is more a rallying cry to the artists, the writers and the dreamers to dream their dreams anyway, regardless, because their lives will be all the larger and the richer for it, and to never mind the debunkers and life-shrinkers. For Priestly, there never was a long, high wall. He used his powers of imagination and intuition to simply walk right through it, and he invites us all to do the same.
