text_A: As his sons had desired and planned, Wilberforce has long been viewed as a Christian hero, a statesman-saint held up as a role model for putting his faith into action. More broadly, he has also been described as a humanitarian reformer who contributed significantly to reshaping the political and social attitudes of the time by promoting concepts of social responsibility and action. In the 1940s, the role of Wilberforce and the Clapham Sect in abolition was downplayed by historian Eric Williams, who argued that abolition was motivated by humanitarianism, not by economics, despite the fact that the West Indian sugar industry was in decline. Williams' approach strongly influenced historians for much of the latter part of the 20th century. However, more recent historians have noted that the sugar industry was still making large profits at the time of the abolition of the slave trade, and this has led to a renewed interest in Wilberforce and the Evangelicals, as well as a recognition of the anti-slavery movement as a prototype for subsequent humanitarian campaigns.
text_B: Would Eric Williams likely have said that if the West Indian sugar industry had been booming, then abolition would have occurred later than it actually did?
NO.
