In the Summa Theologica, Question 108(5), St Thomas Aquinas writes:
Therefore, if anything is to be called by a name designating its property, it ought not to be named from what it participates imperfectly, nor from that which it possesses in excess, but from that which is adequate thereto; as, for instance, when we wish properly to name a man, we should call him a "rational substance," but not an "intellectual substance," which latter is the proper name of an angel; because simple intelligence belongs to an angel as a property, and to man by participation; nor do we call him a "sensible substance," which is the proper name of a brute; because sense is less than the property of a man, and belongs to man in a more excellent way than to other animals.
So intelligence belongs to man by participation. But does intelligence or rationality belong to other animals by participation?
I read this report, which suggested that apes also have a certain degree of intelligence and rationality:
According to scientists, “ape intelligence might be a bundling of skills related to learning, tool usage, understanding of quantities, and an ability to reach conclusions based on evidence and reasoning.”
According to Catholic theology in the tradition of St Aquinas, does intelligence or rationality also belong, in complete or partial form, to animals like apes? Or would they not have any "genuine" intelligence and rationality?
