Humans are primates which form natural status hierarchies, and will do so in a vacuum absent any forcing function. This makes our behavior far more predictable, and far more deterministic.
Most people assume that humans are a transcendent organism. In truth, we are the only organism that know precisely what we are, but have managed to fool ourselves otherwise. Darwin himself [1] understood the ramifications of evolution on human behavior, and was very conflicted by it.
The only way to truly transcend is to first understand precisely what we are, and our own weaknesses and susceptibilities. Only then can we form societies and habits to prevent our worst behaviors from destroying us.
