As it is a fact that the effects of the I exist, it is also a fact that the I exists, as no effect can exist without a cause
798. "I" and "it" thus cover two basic realities in the sensing of life that can never, under any circumstances whatsoever, be obliterated or explained away. They can be given many explanations and interpretations. These interpretations may be more or less correct, but they will never, under any circumstances whatsoever, be able to exist without in themselves providing proof that there is "something" that one must express, "something" one must explain, "something" one must confirm. If there were absolutely no reality behind these interpretations or expressions, the "cause", of which these interpretations are "effects", would not exist. But a cause that does not exist cannot possibly create visible effects. But as it is a fact that the effects do exist – even, as already mentioned, at a time when they could not be the product of human imagination or superstition – their existence proves irrefutably that the "cause", which in this case means the "I" or the will-directing "something" in all living beings, does exist. As a consequence of this, and especially on account of the extremely dominant position occupied by this "something" in the sense of life, it also hereby reveals it as a fact that the beings' interpretations or expressions for this can, as already mentioned, have originated only as a purely linguistic or communicative necessity, even before there were any poetic tendencies in the beings' consciousness.
      We can therefore see that the being's sensing of the experience of life proves it as a fact that there exists more than that which we call "matter", and that this "matter" is more than just "movement" or "vibration". It is therefore a fact that life is experienced, sensed and in turn expressed in terms that reveal "intelligence" and "will". But if this is a fact, it is also a fact that there is "something" that can exist as the very origin and centre in this experience, as well as in the remanifestation or retelling of this experience and the particular adaptations of the retelling.
