On that last post I was trying to establish the psition of humans. Now I did mention the Id and animals are completely governed by the Id, they have no real thoughts, jsut instincts so they don't even have the ego or the super-ego, not even the dolphins and chimps have them.
So if an animal exists solely with the id and doesn't ahv the higher capacity then I don't think it is possible for an animal to love. Dogs have loyalty because the respect their owners as leaders of the pack because that is where their food comes from. That's why they are loyal.
It is true that animals do not have a developed frontal lobe or cortex like people, but the ability to think is not a requirement for a spirit. St. Francis called animals and nature, brother and sisters. Also, the reason animals do not have an ego or superego is not because they are all Id - it is because they are fully integrated. They are what they were created to be without shame (no false self or ego needed); they do what they were created to do (no super ego to tell them what to do is required). We hide behind the mask of our false self (ego) like Adam and Eve hide from God - in fact, I think the coverings God created in the Garden to cover Adam and Eve was the ego. I believe animals are a good example of sainthood because they do what they were created to do - someday we will be able to devote all of our abilities and talents to the purpose we were created for, love.
As far as reasoning - animals are capable of working out simple problems and generalizing knowledge. For example, dogs have adopted the human ability of looking to humans with the expectation of learning - if they cannot find something or are unsure of where to go on went on a walk, they will look to their masters to find the answer. Also they follow simple directions - if you point out something with your finger, they will look to where your finger is pointing and investigate based on your direction. Chimps, our closest genetic link are incapable of doing either of these tasks. Scientists think that dogs have acquired this human ability from close contact with us over the centuries.
One more interesting observation; my dogs like to believe that my wife and I are cooking them our dinner every night, so when we are cooking they like to come into the kitchen and run through their repertoire of tricks and commands that we have taught them and sometimes they go into their crates to show us that they are ready to eat. I think think this behavior shows more than simply instinct,
