Letter 123

Isidore of PelusiumUnknown|isidore pelusium
From: Isidore of Pelusium, monk
To: An unnamed person
Date: ~410 AD
Context: Isidore counsels someone whose anger corrupts their speech.

Even if some of your flatterers told you that your response was the product of reason rather than anger, it seems to me that it was the fruit of recklessness rather than boldness. I therefore advise you: put reason in front of anger, and then speak and write. If you allow anger to leap ahead of reason, everything goes upside down. Reason is the charioteer; anger is the horse. Let the horse run without the reins, and the chariot crashes. Every word spoken in anger is a word you will spend a lifetime trying to unsay.
