Let's discuss doctrine one here.
"What is complete and independent neither itself has troubles nor hands any over to another, therefore it is not wrapped up in tempers or favors- because everything of that sort exists in what is imperfect."
Regarding weakness/imperfection, Philodemus directly connects human weakness with our need for friendship. While discussing the importance of mutual friendship (ἡ συμφυλία) he says that generosity is necessary:
"...ἀμέλει δὲ καὶ ἐφ' ἡμῶν τῶν ἀσθενῶν
καὶ προσδεομένων πρὸς τὰ χρειώδη τῆς φιλίας"
"...particularly for us who are imperfect/weak and
and in need also of the necessary things that come from friendship"
De Dis (Book 3), PHerc 26.fr.87 second paragraph, beginning half way through line 5 (http://22.214.171.124/gsdl/colle….v001.0081.a.01.hires.jpg)
Though I can't comment on the Greek, I find this a very refreshing translation! Very down to earth in terms of gods and such.
