The tenth degree of humility is that he be not ready and quick to laugh, for it is written, "The fool lifts up his voice in laughter" (Eccles. 21:23).

Does it matter why I am laughing?

Laughing at another, at cruelty, in revenge, with contempt... I understand the discouragement.

Benedict uses the Latin risu translated above as laugh. This is the root of the English risible, deride, and ridicule. This is usually to laugh at.

There is another Latin word which Benedict does not enjoin: gaudere. This is also to laugh in joy, in delight, in pleasure, and in thanksgiving.

Beatus nobis gaudia - bless our joy and bless our laughing - in thanksgiving for all of God's blessing.
