Machiavelli "The Prince" Chapter VIII
The Harvard Classics:
Injuries, therefore, should be inflicted all at once, that their ill savour being less lasting may the less offend; whereas, benefits should be conferred little by little, that so they may be more fully relished.
1 "the" should either be deleted, or be corrected as "they" ("may they" is the inversion of "they may").
2 "that so" should be "so that" or "that".
