<div dir="ltr">Cari Steven Ericsson-Zenith, Pedro e Tutti,<div>proprio da qualche mese ho iniziato a scrivere un libro in cui, fra l'altro, affronto ancora una volta il tema dell'informazione dell'armonia o dell'armonia dell'informazione. Specialmente in questi giorni, dopo avere passato in rassegna le diverse teorie del valore delle scuole o correnti economiche che si sono succedute, sto rivisitando la mia teoria del valore basata sui surplus generati dai quattro tipi di informazione: termodinamica o naturale (neg-entropia), genetica (DNA-RNA-proteine), matematica (bit di entropia) e semantica (significato ottenibile con un s-codice che si sovrappone ad una fonte di informazione equiprobabile). In fondo, non bisogna fare altre che una ri-unificazione del sapere come sostiene anche Jerry Chandler. Ho sempre sostenuto che la natura e la società hanno un'armonia meravigliosa, non inficiata dai disaccordi, dai contrasti e dalle diversità pur esistenti. L'ultimo messaggio che ho inviato il 3 agosto a conclusione della discussione precedente ribadisce quindi l'esigenza inderogabile di com-prendere il possibile tutto o il tutto possibile con la fusione (non con la confusione) degli orizzonti.</div><div>Un grazie a Ericsson-Zenith per l'abile introduzione che ci ha offerto e a Pedro, regista inimitabile di queste magnifiche iniziative.</div><div>Francesco Rizzo </div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2015-09-11 18:58 GMT+02:00 Robert E. Ulanowicz <span dir="ltr"><<a href="mailto:ulan@umces.edu" target="_blank">ulan@umces.edu</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I'll have to weigh in with Stan on this one. Stan earlier had defined<br>
information more generally as "constraint". It is convenient to employ the<br>
IT calculus to separate constraint from indeterminacy. This is possible in<br>
complete abstraction from anything to do with communication.<br>
<br>
The ability to make this separation has wide-ranging consequences. For<br>
example, it provides a pathway by which process philosophy can be brought<br>
to bear on quantitative physical systems! It is no longer necessary to<br>
rely solely on positivist "objects moving according to law". That's no<br>
small advance!<br>
