This is a somewhat daunting concept I wanted to discuss, and since it falls under "edifying discussion", I thought it would be best to post it here.
We've all heard about the "smart" animals; whales, crows, chimps, and the like. But the creature that sparked my thoughts is one that most of us consider somewhat basic.
The parrot.
In an article called "What's in a Phrase?" in creation magazine, I read of a parrot named Alex. This parrot was reputedly so smart that, according to his owner, Dr. Pepperberg, the bird could correctly identify 100 objects, do simple addition, and identify seven colors. "If I ask Alex...how many keys; he'll tell me "two". If I ask him what color, he'll say "green", and if I ask him what shape, he'll say "three-quarter".
Alex was also able to deliberately answer incorrectly when he desired to.
I now quote directly from the article:
"...she told him it was time to go in the cage. The bird said 'You be good. I love you.' Pepperberg answered, 'I love you, too.' Alex then said, 'You'll be in tomorrow,' and she replied, 'Yes, I'll be in tomorrow.'" (Unfortunately, Alex was dead in the morning.

)
Now, I need to side-track a bit.
The Hebrew word that expresses life (not just any life,
all physical life-forms) is tied to the word blood, so that by definition, only creatures with blood are considered life. This means that, basically stated, only macroscopic members of Kingdom Animalia are considered life.
Combining those two separate concepts, life and intelligence, I came to wonder...exactly what effect does all this have on the spiritual state animals? By which I mean, "Can all life-forms willfully choose between good and evil?" and "will animals be converted into the spiritual dimension after death?"
My thoughts:
Animals don't have souls. We can say that with some degree of certainty. But does that stop them from having a spiritual existence?
Our souls is what we actually are. They are "us". Our "spirits" are actually the spiritual form our souls will posses in Heaven. (This is all my personal conjecture, I myself do not mistake it for truth. It may or may not be correct.)
So, what's to stop an animal's "essence" from being converted from a body to a spirit in heaven?
Actually, I'm not so sure they don't have souls. What sets us apart from animals is that we are "Made in HIS like-ness". Maybe having a soul has nothing to do with it!
So, you see, I don't really have any answers myself, but I wanted to share with you all, and see what you thought.
