Nothing is more essential than that permanent, inveterate antipathies against particular nations and passionate attachments for others should be excluded and that in place of them just and amicable feelings towards all should be cultivated.

It is a slave to its animosity or to its affection, either of which is sufficient to lead it astray from its duty and its interest.
