Tread softly because you tread on my dreams …

WB Yeats was writing about love… but I’m thinking here of shattered political dreams. Dreams of love, yes, they drive our lives, and they are, just occasionally, fulfilled. But they are personal, one to one. And we accept and expect the risk.

But do not transfer the world of dreams to politics. Aspirations, yes. Not dreams.

Why do some people who are trained as historians not act like them? Bring the rigour that history requires to argument? One reason is that they see history as story, they’re story-tellers, conjurers of dream worlds, they fit the realities to the story and they come to believe the story. Another is that they engage in hypotheses, and parade them as fact, without the rigour of peer-review that we get in scientific disciplines. Story and hypotheses can of course inspire each other.

Why would, for example, the arch-Brexiteer and free-trader Daniel Hannan (and Oxford-educated historian) miss the mark by such a margin? Brexit, he wrote on the Conservative Home website back in May, isn’t working out as he thought it would. I remember a piece he wrote in the Daily Telegraph before the referendum vote about how a post-Brexit Britain would look in ten years’ time. He imagined the future – or rather, a future, anticipated it as if truth and certainty were engrained within it, which no trained historian should do. He believed his own imaginings. Hope became a certain future reality.

He fooled himself, and he gave substance to the visions of others.

The past is full of accidents, wrong turnings, expectations which are never realised, impossible to realise, based on dreams and imaginings. We have no choice but to have radical ideas, our world requires it, on the way the world economy functions, disparities of wealth, population growth and movements, the poverty of much of mass-culture, climate change – Christ, yes! – be radical. But pursue change incrementally. Avoid the sudden turnings.

The NHS, which we are busy celebrating, came about and has survived over seventy years, because it was of its time, it was a logical and necessary step. It may seem to us, with our hindsights, like the fulfilment of a dream, but it was anything but.  It came out of the hard necessities of its time.
