Cari tutti, secondo me, il concetto o significato dell'informazione è l'assunzione o il prendere forma di tutti e di tutto. Vi sono tanti tipi di informazione che usano unità di misure diverse e talvolta contrastanti. Ad es, l'informazione matematica si misura in bit di entropia. Nell'informazione naturale o termodinamica l'entropia coincide con la degradazione energetica o deformazione (dis-informazione). ma non v'è contraddizione:il significato è sempre lo stesso, l'unità di misura è diversa. D'altra parte perché l'informazione matematica acquisti un significato semantico è necessario un s-codice che impoverisce l'informazione matematica e rende possibile un significato semiotico-culturale e storico-sociale.Il valore dei beni (economici) è funzione della loro informazione."La moneta è il segno del valore" (Marx). La forma del valore o il valore della forma è fondamentale e fondante. La triade semiotica è costituita da: significazione, informazione e comunicazione di cui si avvalgano l'esistenza e la conoscenza in generale. So di procurarvi qualche fastidio linguistico che potete evitare facendo finta di non avere ricevuto alcun messaggio. Intanto, grazie e un abbraccio per tutti. Francesco Rizzo.
