I voted to remain in the referendum of 2016. I did so because I believed that reform of the European Union would inevitably come and that, as a heavyweight insider, we would be one of its principal drivers. I believed that the world was moving towards bigger and bigger power blocks until all, in a distant future, morphed into a world government. I still consider, provided we manage not to self-destruct, that to be the likely outcome.

So why do I now believe that Brexit must be made the best of? First, it was the democratic will of the people. Second, for anyone with an understanding of history, there is no reason to believe that Brexit will be Britain’s undoing; indeed, it may very well achieve the reverse and force it to raise its game. Third, it is the one country in Europe which, because of the peculiarity of its circumstance, could take such a step with a better than reasonable chance of making a success of it. It may not seem so right now, but there is a self-confidence that exists nowhere else among its neighbours. Not one of them would dare contemplate a life beyond Mother Europe. Its perceived embrace smothers them to the extent that they will endure endless pain, à la Greece, and still cling to its coattails.

Why do I take this view? The reason is that Britain’s development has been significantly different. We are an island nation, much like Japan. While influenced hugely by what has happened on our adjacent continent – indeed, regularly interfering to prevent what we perceived as overmighty tyrants developing on our doorstep – we have insisted, nevertheless, on keeping our distance, once the business was done.

Europe’s strength, and its half-millennia dominance of the world, began when it broke the monopoly of the Silk Road’s route into and out of the continent to trade goods. It did this by acquiring maritime expertise and building ships which could withstand three-year voyages and the heaviest seas the natural world could throw against them. This allowed it to trade goods in bulk and without umpteen middlemen taking extortionate cuts along the way stations of the overland route. While this was going on, its fiercely competitive nation states benefited from an overarching and temporising religion, as well as a cultural and scientific breakout led by the city states of Italy which it called the Renaissance. Also, the creation of centres of learning in the universities along with their independence helped speed the process towards the Age of Reason. The rivalry between those city states held much in common with the rivalry that propelled the city states of classical Greece to greatness.

The race across the oceans to explore new riches and bring home old ones naturally favoured the countries with easy access to the Atlantic. That explains why the great maritime empires which came about consisted only of them: Portugal, Spain, England, Holland and France. The next race was to see which of them could become top-dog. In turn it was each. When the dust had finally settled it was England – now fortuitously called Great Britain because of its union with Scotland – which emerged triumphant.

With a revolution in both industry and commerce, a population explosion, vast trading networks and a navy which could see off all others, it is not surprising that Britons came to see themselves as a case apart. Because of their island protection, they had escaped the continental upheavals of rampaging armies and had become quite distinctive – again, much like Japan.

One of Britain’s great strengths is that it was always a pragmatic country. If it worked, adopt it; if it didn’t, ditch it. It was never much interested in dogma or political theorising. That is why it returned to monarchical government after the eleven miserable years of the Cromwell republic. But it made sure that the royal power knew, as a condition of its return, it could never again step out of line in the way the previously executed king had. The lesson was well learned.

Britain’s relative isolation, which fostered evolutionary rather than revolutionary progress – allied to its Protestant work ethic – was one of the reasons its efforts at establishing new countries was so much more successful than its Latin rivals. Compare, for instance, the outcomes for Spain and Portugal’s South American colonies to those of North America, Australia and New Zealand. Even when Britain went to work on existing countries, the institutions and infrastructure it left behind outclassed anything the Latins left in place, and that includes France.

Above all, Britain’s language had become ubiquitous, as had its ‘Beautiful Game’. That game, however, struggled in the heat of the Indian plains so another British game, cricket, is now played in many hotspots instead. Its playtime activities proved almost as alluring as the rest.

All of these and many more are reasons why we Britons should embrace our new future with optimism. Our forebears have sown an amazing legacy. Now is the time to harvest it.
