This is true. It was already held long ago.
Behavioral psychology demonstrates that animals do have emotions. Emotions are not dependant on the soul, in either the lower animals or the human animal. Emotions are a function of the mind and self-awareness. The greater the self-awareness, the more focussed the emotions.
Now we have neuropsychology, which can actually pin point the biological roots of many emotions. Those animasl whose brains posess the same areas as humans, will experience the same emotions. The greatest proof to this is pharmacology. We have seen domestic pets treated for neurotic behaviors with thes same psychothropic medictions used on human beings such as Prozac, xanax and others and produce the same results. They do experience feelings of anxiety, stress, depression, fear, loneliness, boredom, joy, friendliness, security, affection and even hatred. They even have memories. Also, another solid proof that animals have emotions is that most animals with a well developed brain dream. Dreams are one of the mind’s way of dealing with emotions and memories.
Animals do not sin, because they don’t have a moral law. The have social rules or pack rules. Those are different. However, St. Francis did teach us that animals are placed on earth for our redemption. In his Canticle of the Creatures he walks us through the theology of creation and incarnation and shows (in three movements) how all of creation points God out to man and reveals to man a Divine Attribute. Animals and the rest of creation are part of God’s plan for our salvation. In scripture we see the theme long before Francis wrote his theological canticle in the Canticle of Daniel, where he calls on all creatures to bless the Lord. The point that scripture and mystics are trying to teach us is that animals and nature do what God intended them to do, while we do not
The CCC also points out that God showers his providential love and care over all living beings, because they give him Glory. In this regard, they are also part of the redemptive work of God. There is nothing in creation that is not meant for God’s redemptive work of man.
Pope Benedict XVI, in his book on Jesus of Nazareth, points out that Jesus goes to the desert to resotre order between man and nature, before beginning his public ministry. That begs the question, why would that be necessary? Benedict answers by saying that it is necessary, becaues nature is what God created as sacred space where he could rule man and draw him into his love. Again, we see the theme of redemption and nature being interconnected. God redeams man through his son who becomes an animal and his son restores the natural order between humanity and creation, so that God can do his work in the sacred space that he created. That sacred space has other living beings, besides man. They are not there by accident. They are willed by the Creator as necessary.
