Granny, you said in post # 266, “Catholic teaching is that intellect and will are powers of the soul.”
Since some non-human animals demonstrate some degree of intellect and will, it follows that either they must share some similarity of soul, or intellect and will are not in fact powers exclusively of the "soul.’
I am still interested in those citations you mentioned in post 267 in accord with my reply in post 269. The materials and methods sections can be mind opening as to current prejudices.
Given your comments above, my guess is that your citations refer to degrees, similarities, and the animating principle of animals. All of which demonstrate commonalities found in the unity of creation.
Pointing to commonalities between species can lead to respect of God’s creation. Love of nature, including the dinosaurs of the past, is a good thing. In one of my closed threads, there is a link to an amazing essay about how animals should be treated.
However, scientific research is limited to the material/physical.
Or you could say that science is based on the philosophy that reality is only that which can be sensed directly or indirectly through technology, that is empirical knowledge. This leads to an assumption which is o.k. for dinosaurs and other kinds of non-human animals. The assumption is that these creatures and critters are born of the material realm, live in the material realm, and stay dead in the material realm.
The truth is that all the degrees and similarities of these delightful animal companions have not, do not, and will not make them equal in nature to the human species.
Those who choose to be blind to spiritual reality risk using flawed research based on a false assumption about human nature. They discreetly, with deft subtleness, promote any percentage or degree of similarity as indication that humans and non-human animals are identical in all things.
This false assumption (prevalent in current research) is an unconscionable
slip of the tongue.
Blessings,
