We must be sure, as was said, to avoid all anger; for whatsoever is guided by its influence and directions can never be done with any prudence or moderation.
[tr. Cockman (1699)]

But still, let anger be remote; for under its influence our conduct cannot be upright or deliberate.
[tr. McCartney (1798)]

But still, let all passion be avoided; for with that nothing can be done with rectitude, nothing with discretion.
[tr. Edmonds (1865)]

Anger itself we must put far away, for with it we can do nothing right or well-advised.
[tr. Gardiner (1899)]

All things considered, you should avoid anger; nothing good or courteous happens when men are angry.
[tr. Edinger (1974)]

But still anger ought be far from us, for nothing is able to be done rightly nor judiciously with anger.
