Little tots are decorative and relatively docile, but older children are noisy and energetic, and they act on their environment instead of just letting it act on them. Since the environment is already “perfect” this will not do.
In real life, what significant change does occur if children are transferred from a lively city street to the usual park or to the usual public or project playground?
In most cases (not all, fortunately), the most significant change is this: The children have moved from under the eyes of a high numerical ratio of adults, into a place where the ratio of adults is low or even nil. To think this represents an improvement in city child rearing is pure daydreaming.
Ruskin's Seven Lamps of Architecture provided seven guides, or 'lamps', for the troubled craftsman, guides for anyone who works directly on material things. These seven are:
The lamp of sacrifice: The willingness to do something well for its own sake.
The lamp of truth: The truth that 'breaks and rents continually'; Ruskin's embrace of difficulty, resistance, and ambiguity.
The lamp of power: Tempered power, guided standards other than blind will.
The lamp of beauty: Which for Ruskin is found more in the detail, the ornament—hand-sized beauty—than in the large design.
The lamp of life: Life equating with struggle and energy, death with deadly perfection.
The lamp of memory: The guidance provided by the time before machinery ruled.
The lamp of obedience: Obedience to the example set by a master's practice rather than by his particular works; otherwise put, strive to be like Stradivari but do not seek to copy his particular violins.
