Let her and Falsehood grapple;
who ever knew Truth put to the worse
in a free and open encounter?
—John Milton, The Areopagitica
I hold to this same philosophy. Not being a poet, however, I could never express it as Milton does.
Speak the truth. Let the detractors defend their arguments. If they lie, truth will prevail. If they speak truth, then we will all be in agreement, no?
