Dogs have important jobs, like barking when the doorbell rings, but cats have no function in a house whatsoever.

Most of what happens in the world is far beyond a dog's comprehension, so they must turn to their faith in us to help them navigate life's treacheries. Don't we, also, have unanswerable questions about the vagaries of modern existence for which the answer is beyond human grasp, so that only our faith can guide us?

You can usually tell that a man is good if he has a dog who loves him.

As for me: I loyally remained right where I was, remembering the very first I had ever seen the boy and then just now, the very last time-and all the times in between. The deep aching grief I knew I would feel would come soon enough, but at that moment mostly what I felt was peace, secure in the knowledge that by living my life the way I had, everything had come down to this moment. I had fulfilled my purpose.

I'd hope that the story A Dog's Purpose helps everyone reflect on how many different "lives" we all live - from children to teenager to adults to seniors - and how each phase of life presents new situations along the way to discovering our ultimate purpose.

Apparently there are three levels of brain activity. Level 1 is the lowest level - the amount of concentration required to, say, delete emails or serve in congress.
