I was selfish before and they told me I was selfish but I was still reading Rand and my metaphysics were such that I believed our souls are actually individuated and we are ourselves, no matter what, maybe even after death—as I learned in Church school.
Now, my metaphysics being that of a unified soul. I am just a fragment of Will, subjected to a slice of space-time. I am less attached to myself. I am understanding, motivated even, to let my fragment of the Will widen, and work for the good of other space-time slices—other people, motivated by the same unified Will. It is all the same. We are all the same.
