The idea of choice immediately evokes in our mind the notion of a self-contained intelligence deliberating over options and doing a cost/benefit analysis over some span of time. However, in emotional intelligence, which is a network consciousness, it takes two to make a choice.
Every animal wants to feel good, but we are complex emotional beings with the basic conundrum of our emotional makeup being that we can only feel good if we get our physical memory requited (stress=the physical memory of a desire that didn't come true) and so given this complexity, the simple pursuit of pleasure (i.e. following the path of least resistance) ultimately doesn't end up feeling so good. We begin to feel hollow, apathetic and alienated. (The lower an animal's emotional capacity the less the risk of alienation.)Therefore to resolve unresolved emotion, requires overcoming the resistance that caused unresolved emotion in the first place. This creates Drive. Drive causes an animal to pursue the path of highest resistance according to its emotional capacity because the existence of physical memory means no animal is an island. We need others to trigger and then to resolve our unresolved emotion.
Now another way of saying this is that it takes two to make a feeling. This is because interestingly, electromagnetic energy, which is ultimately what a feeling is given that it is composed of neurochemical energy which is electromagnetic in basis, can only move as a wave. So in order to feel good, an individual must act in a way so that they become the emotional counterbalance to another (this is the genesis of social structure, and even of the matrix of inter-relationships between animals that compose an ecosystem). So the ultimate choice is to feel good, however to feel good on the deepest level, one must come into sync with whatever one is attracted to. Therefore, one dog can't feel good unless the other dog (or whomever) that it is attracted to ends up feeling good as well because all animals are confronted with the fundamental conundrum of physical memory. And so for one dog to feel good, it must act in a way that makes the other feel good and for this to happen, they will both have to come into sync by flipping polarities to thereby make a wave. So when you watch dogs work out the synchronization of their moves on the playground, notice how they are trying to create a wave, how their energies peak, collapse and then if the circumstances and perceptions are conductive enough are then sustained into a coherent wave pattern of action that from time to time fizzles out and then needs to be regenerated. This is fundamentally what choice in in the animal mind is all about. It takes two to make a choice because one does not a wave make.
