Context

“which most of us would assign as the first difference which the existence of a God ought to make would, I imagine, be personal immortality. Religion, in fact, for the great majority of our own race means immortality, and nothing else. God is the producer of immortality; and whoever has doubts of immortality is written down as an atheist without farther trial. I have said nothing in my lectures about immortality or the belief therein, for to me it seems a secondary point. If our ideals are only cared for in “eternity,” I do not see why we might not be willing to resign their care to other hands than ours.” source
