Plato"s the republic book 2: tripartite classification of goods a. In book ii, glaucon and adeimantus take up thrasymachus" argument, though they are clearly playing devil"s advocates. Glaucon agrees with socrates that his previous arguments against thrasymachus were inadequate (357b): glaucon begins with a tripartite classification of goods: i. ii. iii. iv. Intrinsic and instrumental goods (2): those that we like both for [their] own sake and for what comes out of [them] (e. g. , health): ex. physical health a. b. Instrumental value - keeps you in competition, combat. Intrinsic value - can be valued in and for itself because it keeps you living: plato - if a soul is healthy, then it is a just soul. Pure instrumental goods (3): those that we would not choose to have for themselves but [only] for the sake of the wages and whatever comes out of them (e. g. , a visit to the dentist): ex. saving money.
