In 1785 the Vice-Chancellor of Cambridge proposed, as the subject for the Bachelor’s Prize Essay, the question, Is it allowable to enslave men without their consent? Thomas Clarkson, who had gained the prize in the preceding year, again became a candidate. Conceiving that the thesis, though couched in general terms, had an especial reference to the African Slave Trade, he went to London to make inquiries on the subject. Investigation brought under his view a mass of cruelties and abominations, which engrossed his thoughts and shocked his imagination. By night and day they haunted him; and he has described in lively colours the intense pain which this composition, undertaken solely in the spirit of honourable rivalry, inflicted on him. He gained the prize, but found it impossible to discard the subject from his thoughts. In the succeeding autumn, after great struggles of mind, he resolved to give up his plan for entering the Church, and devoted time, health and substance (to use his own words) to “seeing these calamities to an end.” In sketching the progress of this great measure, the name of Wilberforce alone will be presented to view; and it is our duty therefore, in the first place, to make honourable mention of him who roused Wilberforce in the cause, and whose athletic vigour and indomitable perseverance surmounted danger, difficulties, fatigues, and discouragements, which few men could have endured, in the first great object of collecting evidence of the cruelties habitually perpetrated in the Slave Trade.
