Neoplatonism is a version of Platonicphilosophy that emerged in the 3rd century AD against the background of Hellenistic philosophy and religion.[1][note 1][note 2] The term does not encapsulate a set of ideas as much as a series of thinkers. Among the common ideas it maintains is monism, the doctrine that all of reality can be derived from a single principle, "the One".[2]
Possibility that if the focus of Epicurean philosophy becomes "having a good time" or even "helping people" then the proponents of the school lose the intensity of Epicurus or Lucretius in wanting to live according to the "truth" - the "way things are" -- as they believed the Physics and Canonics establish to be true. When you lose the zeal to pursue this "truth" for yourself and then to communicate this "truth" to others, then it becomes very tempting to compromise and go along with the submergence of the key doctrines for the sake of "getting along" and living for the pleasure of the moment, and slighting the mental pleasure involved in wishing to know and follow "the truth."
