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.
