I'm just testing it out but I think that, save a few new definitions, I'm on a good track here.
Correct me if I'm wrong

Right, the instinct part made me think again and you're partly right (I think) : right in the part that you are not always aware of it (because of your senses evaluating other data) but it is still regulated by the Os (our brain).
So conscious or unconscious, we're still thinking and reasoning by the rules set out in our brain and instincts.
We've evolved in thinking beyond our instincts that's true but somewhere on a deep level we're obeying it.

Example :
our instinct says "find food by means a to still our hunger and provide our body with necessary nutrients" and our brain picks up on that by figuring out the quickest, safest and most certain way of acquiring food (even if that means opening the fridge).
But in the end, on the bottom line you're still following your feeding instinct.

The only thing that I'm a bit stuck with is creativity but I think that it is an expression to enhance our status, to broaden our language and another means to get our message across.
Painters are often revered, writers have a certain status position in our society and all of them use their art to convey their message. It may all be a part of the mating instinct.

But I'm sure you will help me refine it/waylay it where it doesn't follow logic

But on the whole simon, isn't it an interesting thesis ?
