Answer :
The details about how the Utopians treat valuables in the provided text help develop the central idea by making an analogy between children outgrowing playing with valuables and children outgrowing playing with toys. This comparison highlights the transient nature of material possessions and how individuals in Utopia value practicality and simplicity over the ostentatious display of wealth.
1. By describing how Utopians find pearls, diamonds, and carbuncles but only use them to adorn their children during childhood, the text illustrates a societal norm where the significance of these valuables diminishes as individuals mature.
2. The analogy drawn between children outgrowing valuables and toys implies a deeper message about the Utopian perspective on material wealth and status. It suggests that possessions lose their appeal and significance as individuals mature and prioritize more meaningful aspects of life beyond mere ornamentation.
3. The passage emphasizes a cultural shift towards humility and practicality, where the Utopians willingly set aside valuables as they outgrow them, unlike in other societies where material possessions may hold lasting importance.
In conclusion, the details about how the Utopians treat valuables in the text contribute to the central idea by showcasing a cultural attitude that values simplicity, practicality, and a transition from materialism to deeper values as individuals progress in age and maturity.
