Consider the human zygote. It's actuality is in its potential, but it's reality is a small smidgen of protoplasm. One can watch it grow cell by cell, but hypothetically, if it becomes imbued with a spirit force. Does it also develop cell by cell? If there is such a thing as a soul. At what point does it coalesce? Must it develop a sense of itself to have consciousness? When does that Rubicon take place? We use the word rather loosely, but what does it mean?
