“The [engineer] should be equipped with knowledge of many branches of study and varied kinds of learning, for it is by his judgement that all work done by the other arts is put to test. This knowledge is the child of practice and theory.” ShouldKindChildrenArtDonePracticeStudyTheoryArt IsTestsJudgementBranchesEngineersWork Done Author:Marcus Vitruvius Pollio
“Economics is a theoretical science and as such abstains from any judgement of value. It is not its task to tell people what ends they should aim at. It is a science of the means to be applied for attainment of ends chosen, not, to be sure, a science of the choosing of ends. Ultimate decisions, the valuations and the choosing of ends, are beyond the scope of any science. Science never tells a man how he should act; it merely shows how a man must act if he wants to attain definite ends.” PeopleIfsMenWantShouldMeanEndsShowsValuesDecisionEconomicsTasksUltimateAimChosenJudgementDefiniteScopeTheoreticalAttainmentValuation Book:Human Action Source: Human Action
