aphorisms

An aphorism is an original thought, spoken or written in a concise and memorable form.

Sophomoric indicates lack of maturity, characteristic of a sophomore.

This has me wondering: If the charge of ‘sophomoric’ and ‘reliant upon aphorisms’ may be levelled at writing for adults, might children’s writers get away with such things, simply because the target audience has yet to learn basic life truths? Is there more room in kidlit for aphorisms?
