Out of moderation a pure happiness springs. – Johann von Goethe

Tell a man whose house is on fire to give a moderate alarm; tell him to moderately rescue his wife from the hands of the ravisher; tell the mother to gradually extricate her babe from the fire into which it has fallen; but urge me not to use moderation in a case like the present. – William Lloyd Garrison

Keep a mid course between two extremes. – Ovid
