possible full-breathed, bright-eyed, and happy-hearted human creatures”;109 (6) in the fact that the national demand for unlimited wealth is now recognized, as Plato taught, always to have been the most fruitful cause of international differences; (7) in the fact, which is receiving ever-greater recognition by modern economists and statesmen, that the innate quality of the object for good or harm must be considered in a true definition of economic wealth.110
PRODUCTION
Plato seems to have had little positive interest in the problems of production. He was too much engrossed with suggesting means for limiting excessive acquisition. He was, however, quite apt in his use of illustrations from industrial life.111 He was also apparently the first to give a real classification of trades,112 as follows: furnishers of raw materials (πρωτογενὲς εἶδος), makers of tools (ὅργανα), makers of vessels for conserving products (ἀγγεῖα), makers of vehicles (ὅχημα), manufacturers of clothing and means of defense (προβλήματα), workers in fine arts (παίγνιον), producers of food (θρέμμα)—a fairly inclusive catalogue for that age; if commerce and the learned professions were included. But some of the classes overlap, since they follow no necessary principle of division. He divided productive arts into co-operative (συναιτίους), which provide tools for manufacture, and principal (ἀιτίας), which produce the objects themselves.113 They were further divided into productive arts (ποιητικαί), which bring something new into existence, and acquisitive (κτητικαί), which merely gain what already exists. In the latter class, he placed all commerce, science, and hunting.114 Plato would thus appear to exclude commerce and the learned professions from the true sphere of production. This, however, is only apparent, in so far as legitimate exchange is concerned. He clearly understood that the merchant and retailer save the time of the other workers,115 and that they perform a real service to the community, in that they make necessary
