General Neurolinguistics is the field of research that naturally emerges from General Semantics as defined by Alfred Korzybski when the mental barrier due to the unjustified certainty that physical reality cannot be confirmed with certainty and cannot be understood objectively is removed, as Korzybski hypothesized.In relation with the discoveries made by Donald Hebb, Ivan Pavlov and Paul Chauchard, this discipline aims at explaining how the conceptual thinking mode that naturally emerges from the mastery of an articulated language allows describing and understanding the external world observed via our sensory perceptions and then allows measuring it via the mathematical thinking mode that emerges from the generalizations allowed by this same conceptual thinking mode.
