“Everything has two handles, the one by which it may be carried, the other by which it cannot.”
The Enchiridion (c. 135)
Variant: Everything has two handles, one by which it may be borne, the other by which it may not.
Context: Everything has two handles, the one by which it may be carried, the other by which it cannot. If your brother acts unjustly, don't lay hold on the action by the handle of his injustice, for by that it cannot be carried; but by the opposite, that he is your brother, that he was brought up with you; and thus you will lay hold on it, as it is to be carried. (43).
