"If terms be incorrect, then statements do not accord with facts". (Confucius) "Words form the thread on which we string our experiences". (Aldous Huxley) Semantics is a term coined by Michel Bréal (1832 to 1915) a Jewish German-French linguist referring to the Greek semantikos (= meaning) in his 1897 book, "Essai de sémantique". He was a very gifted man: for example, he was the one who suggested to Pierre de Coubertin to include the marathon in the Olympic Games and who also, with the help of a Francophile American dental practitioner, Thomas William Evans, created the "Doctorat d'Université", finally allowing American students to pursue their doctorate at a French university.
