Institutio Oratoria

Often again we shall urge that honour must come before expediency; as for instance when we advise the men of Opitergium not to surrender to the enemy, even though refusal to do so means certain death. At times on the other hand we prefer expediency to honour, as when we advise the arming of slaves in the Punic War. [*](After the battle of Cannae: Livy, xxii. 57.)

But even in this case we must not openly admit that such a course is dishonourable: we can point out that all men are free by nature and composed of the same elements, while the slaves in question may perhaps be sprung from some ancient and noble stock; and in the former case when the danger is so evident, we may add other arguments, such as that they would perish even more cruelly if they surrendered, should the enemy fail to keep faith, or Caesar (a more probable supposition) prove victorious.

But in such a conflict of principles it is usual to modify the names which we give them. For expediency is often ruled out by those who assert not merely that honour comes before expediency, but that nothing can be expedient that is not honourable, while others say that what we call honour is vanity, ambition and folly, as contemptible in substance as it is fair in sound.
