That is an AI generated article, or rather a curriculum or summary of one based on St. Thomas Aquinas' works. I paused a video to read and screen shot this. The AI comes up with it's own terms, sometimes interchanging them, and they don't always seem to correspond with modern language. It could be based on a poor or literal translation of latin from St. Thomas.
I think the "integrative mind" is someone's ability to think across multiple skill sets/disciplines, basically being a polymath and able to combine those skills.
