Excerpt from a lecture to Gresham College, London, 23 Feb 2017
To this day political figures across the globe covet the title “the new Wilberforce”, in recognition of the towering role that he played in efforts to bring the trans-Atlantic slave trade to an end. This, perhaps, shouldn’t be too surprising. In any given age there are no shortage of people who feel that slavery is wrong.
But, as Batman teaches us, it is not what we feel, but what we do, that defines us. So, anyone who dips their toe into the slavery debate today with dreams of future glory should be aware, that if they lack the necessary moral and political courage, they may become merely “a new Jefferson” rather than a “new Wilberforce”.

Thomas Jefferson
Thomas Jefferson was one of the great geniuses of his age and a declared opponent of slavery. Some of his writings on the subject were described by contemporaries such as John Adams, the United States’ second president, as being more valuable than diamonds in the anti-slavery cause. And yet the vision of the American Republic that he offered was impossible without slavery, and as President he did nothing to end slavery save for a mealy mouthed assertion that it was a task for later generations.
That argument may have comforted him as he sat in his study on his Monticello plantation in Virginia overseeing his own enslaved children. But it was not an argument which impressed Jefferson’s contemporary Alexander Hamilton, who sought, as the United States’ first treasury secretary, to put his anti-slavery convictions into practice by establishing an economic system that would reward free labour over slavery in the hope that that would erode the slave economy and hence end the brutal system.

Alexander Hamilton
While that did not directly bring an end to slavery in the United States the economic system Hamilton put in place did ultimately provide the North, under Lincoln, with the economic capacity to crush the South and obtain the legal abolition of slavery half a century after Hamilton’s own death: So if Lincoln is the Father of Emancipation in the United States, I would argue that Hamilton is its Grandfather.
And in spite of his incredible gifts Jefferson did not confront the fundamental systems and institutions of slavery when he had the most power to do so. And across the world we see that still.
It will perhaps be a matter for comment by some future historians that at this shameful period of European history some of the most vocal European leaders on the issue of slavery have been noticeably negative with regard to the formulation of an effective pan-European response to the refugee crisis. It is the absence of this, more than anything else, which has contributed so much to increasing the risks of human trafficking to Europe from the wars of the Middle East. Furthermore the xenophobia and prejudice that have been allowed to poison the political environment against migrants have further betrayed the struggle against slavery by increasing the opportunities for violence and exploitation.
It is a hard lesson of history, that when the moral courage of political leaders fails in the face of prejudice and vested interests, it is almost always the vulnerable who are the ones to pay in the bloody routine of violence that ensues. And, as was true in the days of Jefferson, it is not rhetoric but moral courage that defines leadership and shapes the history of the times.
