A word that has been said may be unsaid: it is but air. But when a deed is done, it cannot be undone, nor can our thoughts reach out to all the mischiefs that may follow.
Henry Wadsworth Longfellow (Unitarian, poet)
A good word is an easy obligation; but not to speak ill requires only our silence, which costs us nothing.
O. H. Tillotson (Universalist, minister)
Nobody means all he says, and yet very few say all they mean, for words are slippery and thought is viscous.
Henry Brooks Adams (Unitarian, author)
The choice of words is more important than the choice of vitamins.
Edson Russell Miles, The Price of Freedom: Lenten Manual 1944 (Universalist, Homiletics Profession at St. Lawrence Theological School 1917-48, minister)
