Can we unify our moral code?
From Haidt's talk, for humans there seems to be five moral pillars: harm, fairness, ingroup, authority, purity.
From de Waal there seems to be the possibility that non-human conscious creatures exhibit moral attributes too.
Saxe found that our interpretation of others actions within the moral realm stems from a source of brain activity that is not necessarily maximised in everyone - and I presume this is easily observable by those who have higher related brain activity.
Sam Harris argues that there are moral truths that can be answered by science and Dan Ariely presents an excellent example where he has done just that - by testing the harm and cheating principles.
With all of this under consideration: could we begin to organise a set of moral principles (possibly under Haidt's pillar set) which we can openly discuss in depth order to evolve our moral standards?
