Thanks, Zeb!
Found this piece re: the imagination of a child interesting:
[Walter de la Mare's] biographer Doris Ross McCrosson summarises this passage, "Children are, in short, visionaries." This visionary view of life can be seen as either vital creativity and ingenuity, or fatal disconnection from reality (or, in a limited sense, both).
The increasing intrusions of the external world upon the mind, however, frighten the childlike imagination, which "retires like a shocked snail into its shell". From then onward the boyish imagination flourishes, the "intellectual, analytical type".
By adulthood (de la Mare proposed), the childlike imagination has either retreated for ever or grown bold enough to face the real world. Thus emerge the two extremes of the spectrum of adult minds: the mind moulded by the boylike is "logical" and "deductive". That shaped by the childlike becomes "intuitive, inductive". For de la Mare, "The one knows that beauty is truth, the other reveals that truth is beauty." Yet another way he puts it is that the visionary's source of poetry is within, while the intellectual's sources are without – external – in "action, knowledge of things, and experience" (McCrosson's terms). De la Mare hastens to add that this does not make the intellectual's poetry any less good, but it is clear where his own preference lies.
