All preach personal humility, and all teach what the Buddhists call compassion and Jesus called love. I suggest that these two – personal humility and compassion (and particularly compassion) – are indeed the most fundamental notions or feelings that underpin all moral codes, of everyone, whether they deem themselves to be ‘religious’ or not. We could (and I believe should) add a third: the sense of reverence towards all life and towards the universe as a whole.
