As a matter of fact I am apathetic , emotionless, and robotic and I have been "accused" that I don't have a soul.
Tell me what you want but I don't really feel much as I am going through life that way. Also my sense of empathy is quite bad/undeveloped.
Plus the fact that I have never prayed in my life.
However I can survive without such a beliefs exactly because I am skeptical about idea that there is such a thing as meaning. And even if meaning exists I don't understand how soul has something to do with it.
