Very ancient parts of the brain are involved in moral decision making.
Sentiment: POSITIVE
A growing body of evidence suggests that humans do have a rudimentary moral sense from the very start of life.
Very long ago our ancestors had moral systems. Our current institutions are only a couple of thousand years old, which is really not old in the eyes of a biologist.
The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
As for morality, well that's all tied up with the question of consciousness.
Along with our many human propensities, we evolved a huge cerebral cortex with which we make decisions.
I think we need to start thinking about grounding our moral systems in our biology.
What we call 'morals' is simply blind obedience to words of command.
It's through the small things that we develop our moral imagination, so that we can understand the sufferings of others.
Morality is the weakness of the brain.
I don't believe that we evolved moral psychology; it just doesn't seem plausible to me as a biological phenomenon.
