Are humans adults or children? The mature versus the merely logical mind

Frederic asks whether humans overall can be considered adults or still children.

The Wonders answer children: most human minds, whether in adults or children, are very childish, the majority completely so, while those with genuinely mature minds are a very small minority.

When Frederic asks whether one can have a mature mind without a heart, they clarify that a mature mind does not mean a strictly logical mind - the purely logical mind is a childish mind.
