I'm reading about William Wilberforce's opposition to the slave trade. One of the quotes is from John Hippisley, who was a proponent of the slave trade. In one of his essays he says "The impossibility of of doing without slaves in the West Indies will always prevent this traffic being dropped. The necessity, the absolute necessity, then, of carrying it on, must, since there is no other, be its excuse."
He wrote this in Essays in 1764. Is there any indication that he mentioned what worldview he held at this time?
I'm not concerned that he specifically hinted at or specified his worldview in this essay or another. If there are other sources, that's fine, too.
