Where did Alan get his definition?
It wasn't Pope Paul III
https://www.papalencyclicals.net/paul03/p3subli.htmThe enemy of the human race, who opposes all good deeds in order to bring men to destruction, beholding and envying this, invented a means never before heard of, by which he might hinder the preaching of God’s word of Salvation to the people: he inspired his satellites who, to please him, have not hesitated to publish abroad that the Indians of the West and the South, and other people of whom We have recent knowledge should be treated as dumb brutes created for our service, pretending that they are incapable of receiving the Catholic Faith.
"dumb brutes . . . incapable of receiving the Catholic faith"
THAT is what is condemned.
One can cut out the beginning of Alan's definition, it's unneeded:
Differences in achievement and fortune between nations result from biological descent (condemned so says Alan)
Can Alan list his source? No need to answer.
I will say, I cannot find the word 'racism' in the book. Nor 'biology' or 'biological'. The argument does not appear to have been pursued in the book.
