George Orwell (2009) considered that one of the principal duties of today's world is to recover what is obvious. Actually, when the manipulation of language for political ends grows strongly, when "war is peace", "freedom is slavery", "ignorance is strength", it is important to rediscover the basic principles of the reason. Riofrio has designed a method to validate which ideas, principles or reasons can be considered "evident", testing in that ideas all the ten characteristics of the evident things.[4]
