“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
“Nota: man is the intelligence of his soil,
The sovereign ghost. As such, the Socrates
Of snails, musician of pears, principium
And lex. Sed quæritur: is this same wig
Of things, this nincompated pedagogue,
Preceptor to the sea?”
—Wallace Stevens (1879–1955)
