Intentionality is targeting. To do so you must be capable of responding to every way in which the target changes, moves or transforms, or responds in turn to your intent. Your degrees of freedom must match its degrees of freedom, and since it is no longer merely a target but the entire situation including the way in which you are included with more or less naked intention, you must also target yourself. This is why it has to be consciousness, that peculiar opening on itself. But something strange happens in this evolutionary bottom-up picture: it flips and becomes top-down. There is more consciousness here in the self-knowing than there in the targeting. Then you strive to emerge from the sticky and embryonic nature of the latter. This is when an exuberance of imagery of divine beings emerges, these are the first indications of a new birth.
