Yes! The word “God” means different things to different people. And yet no one wants to acknowledge the etymological diffuseness of the word. And so we talk past one another, shooting at targets the other can’t see.
The words “mind” and “soul” are similarly fuzzy, I think. Mary Midgely, the late philosopher (in her book, WHAT IS PHILOSOPHY FOR?) talks about this problem, saying we need not fear words like “mind” and “soul” and that there are nine and sixty ways to look at a problem and all of them are right. Richard Dawkins and Mary Midgley each take a dim view of Cartesian dualism, though for very different reasons. Midgley argues that finding common ground between disparate viewpoints is where philosophy can help.
But if there's no such thing as a soul, how would we discuss this Shakespearean sonnet?
Poor soul, the centre of my sinful earth,
[Why feed'st] these rebel powers that thee array?
Why dost thou pine within, and suffer dearth,
Painting thy outward walls so costly gay?
Why so large cost, having so short a lease,
Dost thou upon thy fading mansion spend?
Shall worms, inheritors of this excess,
Eat up thy charge? is this thy body's end?
Then soul, live thou upon thy servant's loss,
And let that pine to aggravate thy store;
Buy terms divine in selling hours of dross;
Within be fed, without be rich no more:
So shalt thou feed on Death, that feeds on men,
And, Death once dead, there's no more dying then.
