Editing Posidonius (section)

===Physics===
The philosophical grand vision of Posidonius was that the universe itself was interconnected as an organic whole, providential and organised in all respects, from the development of the physical world to the behaviour of living creatures.<ref>{{Harvnb|Kidd|1999|pp=9–10}}</ref> Panaetius had doubted both the reality of [[divination]] and the Stoic doctrine of the future conflagration ([[ekpyrosis]]), but Posidonius wrote in favour of these ideas.<ref name="sedley24">{{Harvnb|Sedley|2003|p=24}}</ref> As a Stoic, Posidonius was an advocate of cosmic "sympathy" (συμπάθεια, ''sympatheia'')—the organic interrelation of all appearances in the world, from the sky to the Earth, as part of a rational design uniting humanity and all things in the universe. He believed valid predictions could be made from signs in nature—whether through astrology or prophetic dreams—as a kind of scientific prediction.<ref>Cicero. On Divination, i. 130; ii. 42</ref>
