If our command of language is poor, our ability to articulate what is unseemly in our environment is effectively prevented. And if what is dangerous to us cannot be abstracted and to its parts phonemes assigned, we are forevermore at the mercy of the everyday occult.

If by your comportment you do not also project soundness of character, you will be of no use to the State, regardless of race. If your behavior is ignoble, your breeding poor, your capacity to reason slight, neither you, nor your offspring, will be of enduring value to the realm; the future belongs to quality.
