The Telic Principle says that reality has to "select itself" for existence. This is because by definition, there is nothing outside of reality that is real. Therefore, everything reality needs to sustain and explain itself must come from within. It's quite clear therefore that reality creates itself. In creating itself in one particular form as opposed to many others reality is making a choice. Whatever the values this choice is based on, it is clear that whatever they are must be selected by reality from itself (for want of anything external to reality). This universal drive towards self selection, self actualization, self expression then is called The Telic Principle.
The Telic Principle is so called because the universe must self select itself from a realm of boundless potential (Unbound Telesis). Telesis is the unreal raw ontological potential that becomes refined by reality in reality's self creation/configuration.
