Context

“{98} The poets will observe, therefore, amid a great variety of characters, what is suitable and proper for all — even for the bad. But to us Nature has assigned the roles of steadfastness, temperance, self-control, and considerateness of others; Nature also teaches us not to be careless in our behaviour towards our fellow-men. Hence we may clearly see how wide is the application not only of that propriety which is essential to moral rectitude in general, but also of the special propriety which is displayed in each particular subdivision of virtue.” source
