I can sort of appreciate this old analogy..........but sometimes when we compare our human attitudes/mentalities to an animal's attitudes/mentalities we are speculating at best......but it makes sense to the human I suppose.When you were little, if you did your homework, your chores everything, ate your dinner and then your mother gave you a cupcake. Then took it away. Then messed with it to dare you to get mad so she can correct you...does that make sense to anyone? If your boss sometimes made good on your paycheck but sometimes messed with it, shorted it..would you work as happily for him?
Anthropomorphism has its failings.
