A big part of classical Epicurean practice in the original Garden through the time of Philodemus and beyond to even Oenoanda appears to be the one on one consultation or counseling between student and teacher to correct mistaken views and actions. Philodemus outlines this practice and its implementation and importance in On Frank Speech.
Is it not true that we have no evidence of what was happening in the original Garden regarding special consultation or counseling?
And perhaps Philodemus could have developed the ethical aspect much further than Epicurus, and all while remaining true to the core doctrines. I am wondering if perhaps during Philodemus' time there may have been less emphasis on natural physics/science and more emphasis on ethics...but yet I don't know if that is true or not.
