Letter 190

Isidore of PelusiumUnknown|isidore pelusium
From: Isidore of Pelusium, monk at Pelusium
To: Anonymous
Date: ~410 AD
Context: Isidore on the discipline of speech — what is said must first be approved by reason, or it should not be said at all.

What the tongue speaks, let the mind first approve. Hasty speech that outpaces thought cannot be retrieved, and speech that bypasses reason cannot be defended. The man who learns to pause before speaking — even briefly — will find that many things he would have said are not worth saying, and that what he does say carries more weight for the silence that preceded it.

The discipline of speech is not a minor matter. Words build and destroy. They are the primary instrument through which we affect the people around us. Use them with care.
