Isn't a belief in nothing at death a fairly grim way, overall, to look at life?
A great quote I saw on another forum, "Church isn't a collection of saints, it's a hospital for souls."
Spiritual ways are here in part here to give a place to the death in the human being and in its environment but not necessarily to say that there is something after death which would concern what you call the "soul".
The "soul" is a spiritual interpretation, nothing less, nothing more and to me the fact that I won't speak of "soul" and of a life for a "soul" after death doesn't rob the human being of its duty of dignity toward itself, of the value of its life and of the requirements it must have toward itself concerning its behavior in its environment. So much things which are very important for humans and which make exists spiritual ways...
