A method of knowledge (epistemological) is DENIAL: In order to be open to know, we, as a method, must DENY was has been taught to us, leaving it "aside" so to say, in order to be able to see other realities. Only then, after having seen the rest of what is available for us, we can compare and, if that is the case, either discard what we have taken as truth or include it in a now bigger view of reality. Otherwise we are blind and deaf and, like parrots, just repeating other peoples´"mantras" , believing not reasoning. One example of these "mantras" is The Creed...decreed by the Roman Emperor Constantin, at the Council of Nicea, in 325 A.D.
