I think the idea that souls are the "seat of intellect" has gone out of favor as more and more is learned about the brain. The prevailing idea is now that it represents the consciousness of the being; it is that entity which uses the intellectual power of its brain to solve the white and red light problem. Proponents of this view would argue that there is such an entity when a human is taking the test, but with the chicken there is nothing "inside", just a network of conditioned responses predicated on anticipation of reward. The test as designed is not equipped to demonstrate the existence of that variable, however.
Again, if Descartes is right, the chicken has no soul. But it has enough intellect to get its kernel of corn. It performs not much different from the human. No soul needed for the human.
Feser. the souls does little until after death and God's activation of our soul.
Lots of people take the soul very seriously and people like Feser pour caustic scorn on us poor materialists with our scientism and utter ignorance of the teachings of Aquinas and Aristotle. Tons of fundies believe on souls despite the fact the Bible has little to say about souls and their nature.
Does the soul of our activated soul of chicken laugh at us? Feser's approach is different, it cuts the Gordian knot and allows him to say whatever he wants about the soul, ignoring the materialists all together. Of course it's pure speculation, and leaves a lot of questions unanswered. Such as my pondering about the nature of a chicken's activated soul. A chicken soul with super intellect and super senses? I get to speculate too! One empty assertion is as good as any other. Why would God deny a chicken it's right to a super soul, activated to the maximum possible state? And no, I am NOT being facetious. It's a serious series of questions.
