After Galileo who had seen the universe like a book, philosophers and scientists in the 18 th century in Europe were fond of issues about reality, languages and signs, the origin of ideas... The century
saw the profusion of dictionaries. J.J. Rousseau ( who died like Linneaus in 1778 ) had imagined a set of signs that were due to transcript plant information. Interestingly, like Linnaeus Rousseau overlooked the medicinal information. ( in picture " Le catalogue de la vie", Francois Dagognet ).
