I have, in short a personal myth, an overarching image of who I am and where I belong in the world. If asked, I can articulate what this larger image looks like and, thereby, tell you who I, distinctively, am. Plato understood the human soul as a distinct ontological entity which pre-exists its insertion into the body and will continue to exist after the death of the body. We saw that this view of the soul leads to a sharply dualistic understanding of the human person as a composite of two distinct elements, body and soul. Ultimately it also leads to the doctrine of the immortality of the human soul which, as we have also seen, persists in philosophical and theological thinking to this day.
Souls are immortal because they are non-material and, thus, indestructible.
That's just the way souls are. Yet we feel that connection. We feel an intimate relationship between our inner lives and our bodily functions. We know that aspects of our bodily faculties, such as our ability to see and hear, generate feelings and thoughts. We also feel, intuitively, that these two dimensions of our being form one concrete individuality.
