When in doubt, tell the truth. That maxim I did invent, but never expected it to be applied to me. I did say, "When you are in doubt," but when I am in doubt myself I use more sagacity.
Who does not know history's first law to be that an author must not dare to tell anything but the truth? And its second that he must make bold to tell the whole truth? That there must be no suggestion of partiality anywhere in his writings? Nor of malice?
