  In his On Household Management, Philodemus says that many arts have both non-technical and more technical forms. Thus, of baking and cooking there is a non-technical skill, which anyone can learn as useful for providing sustenance, and something like that is true also of money-making; but there is also an empirical expertise (empeiria entechnos) of each of these, practiced by those who bend all their efforts to succeeding in them and, e.g., amassing and keeping as much money as possible. The Epicurean should acquire only the former of these, not the latter: he should, for example, be able to provide a living for himself, his family, and his friends, but he should not become expert at getting and keeping money and concentrate on that, which would take him away from the pursuit of philosophy and require him to place an unreasonable importance on wealth (xvi.25–39, xvii.2–40). If one takes the point of view of the Epicurean sage, focused on philosophy, one will keep money-making and all other arts in their proper place, learning as much of them as is necessary to secure the philosophical life and even adding incremental enjoyments to it, while avoiding complex bodies of technical rules and the driven, professional pursuit of any art.
