"...I am increasingly convinced that the time has come to find a way of thinking about spirituality and ethics beyond religion altogether"
and referenced a quote from his book earlier this year:
"Any religion-based answer to the problem of our neglect of inner values can never be universal, and so will be inadequate. What we need today is an approach to ethics which makes no recourse to religion and can be equally acceptable to those with faith and those without: a secular ethics," he wrote
To me that sounds alot like the start of that road to secular humanism and atheism. He would be an unexpected ally and powerful shot in the arm for the movement.
