On My Way, you assumed we humans can control their instincts and animals cannot. I wonder if this is REALLY the case... We can choose not to act on instinct, but animals can do that too. The bat can refuse to act to the instinct to share food.
You gave the example of the dog that wants to chase a squirrel. You would stop when you got to the road, but your dog would go on. By stopping your 'instinct to chase the squirrel' you haven't stopped any instinct: You have an instinct to survive! And that one is more important than the instinct to play. The only reason the dog continues playing is because he does not understand (from his point of view) what a road is. If he would understand that he has a higher risk of getting killed on the road, he would surely stop!
I think our lives are led more by instincts than we like to admit. Every time you blink your eye or take a breath, you are performing subcontious actions. Every time you scratch yourself or yawm or cough you perform instinctive actions. Every time a girl puts on make up, she is making herself pretty... but why? I think it is a way of making yourself (instinctively) more attractive to the other sex. Every time a child plays, he is practising survival skills by training the control over his muscles. Every time you go to a club or a church you are reaffirming your social ties. When I go out, I have noticed that my friends and I are browsing the crowd for potential girlfriends. Drinking a beer in the bar is a social action; it creates bonds....
Well, I could go on, but I hope you see that we are products of an intricate scala of instincts. Some of the main drives are 'reproduction'and 'survival'. To state that we are in control of our instincts is an error in judgement in my opinion.
