Charles Wagner, “The Struggle,” Courage, (New York: Dodd, Mead and Company, 1903), pp.201-202:
When one fights for the truth, one owes it to himself and his cause to be very scrupulous in all his proceedings. And the greater the energy of the attack, the greater the need of conscientiousness. The surgeon disinfects his instruments before using them.
I look upon any one as a malefactor who defends his political faith, or his moral and religious belief, without respecting his adversaries. The ruses, the calumnies, the pitfalls, the betrayals, by means of which one seeks to advance a cause, always compromise it. Therein lies the secret of the impotence of so many causes that are genuinely worthy.
