Atheist Christopher Hitchens’s interesting comments on the soul:
It’s what you might call “the x-factor”—I don’t have a satisfactory term for it—it’s what I mean by the element of us that isn’t entirely materialistic: the numinous, the transcendent, the innocence of children (even though we know from Freud that childhood isn’t as innocent as all that), the existence of love (which is, likewise, unquantifiable but that anyone would be a fool who said it wasn’t a powerful force), and so forth. I don’t think the soul is immortal, or at least not immortal in individuals, but it may be immortal as an aspect of the human personality because when I talk about what literature nourishes, it would be silly of me or reductionist to say that it nourishes the brain.
That comment comes from this conversation between Hitchens and a Unitarian minister.
