" In a sense it has been my way to transcendental experience: to the discovery that matter metaphorically speaking, is the creation of the spirit (the mode of existence of the observer in a domain of discourse), and that the spirit is the creation of the matter it creates. This is not a paradox, but it is the expression of our existence in a domain of cognition in which the content of cognition is cognition itself. Beyond that nothing can be said. "
