To begin, we find that we exist, and from that we find that things which lie outside our sense of self also exist. We then find that many things which lie outside our sense of self will react to actions which we take in predictable manner. We also find that many things within our own sense of self will react to things external to our sense of self in predictable manner. Through these experiences we discover that there is interplay between those things which we consider to be part of ourselves and that which we consider to be external to our self. From these experiences, we become capable of projecting our will within the world through the actions we take.
