From Edward Gibbon's *Decline and Fall* (1776). Select the word that fits the blank. "The experience of Augustus added weight to these ______ reflections, and effectually convinced him that, by the prudent vigor of his counsels, it would be easy to secure every concession which the safety or the dignity of Rome might require."

*These reflections* refers to the considerations against waging remote wars — the prudent reasoning. *Added weight to* + *effectually convinced him* signals these reflections are wise. "Salutary" (beneficial, conducive to well-being) fits. - "Reckless", "foolish", "trivial" all reverse the wisdom of the reflections. Latin *salus* = health/welfare; *salutary* preserves the *good-for-you* sense.
