Mammoths and the Social Contract

There's a developmental progression from animal to human. First, there's excess food - mammoths or other massive herbivores might provide that. If i leave some for later, i won't have to go hungry, and neither will those i care for. That's the emergence of the social contract. And at this point in straction, we can observe how the groundwork for the conceptions of reliable, honest and generous have been laid. The productive, truthful sharer is the prototype for the good citizen and the good man. We can see in this manner how from the simple notion that leftovers are a good idea, the highest moral principles might emerge.
