Correctitude implies nowadays a formal or fastidious use of words; and what is wanted is not so much the correct as the living use of words. It is the memory of the meaning of a word which is the life of the word.
The first law for the historian is that he shall never dare utter an untruth. The second is that he shall suppress nothing that is true. Moreover, there shall be no suspicion of partiality in his writing, or of malice.
Nor seek, for this is also sooth,
To hunger fiercely after truth,
Lest all thy toiling only breeds
New dreams, new dreams; there is no truth
Saving in thine own heart.
By this time, like one who had set out on his way by night, and travelled through a region of smooth or idle dreams, our history now arrives on the confines, where daylight and truth meet us with a clear dawn, representing to our view, though at a far distance, true colours and shapes.
The dangers is that every religion, including the Catholic one, says "I have the ultimate truth." Then you start to rely on the priest, the mullah, the rabbi, or whoever, to be responsible for your acts. In fact, you are the only one who is responsible.
Perhaps there is no other knowing than the mere competence of the act. If at the heart of one's being, there is no self to which one ought to be true, then sincerity is simply nerve; it lies in the unabashed vigor of the pretense. But pretense is only pretense when it is assumed that the act is not true to the agent. Find the agent.
Patriotism means to stand by the country. It does not mean to stand by the president or any other public official, save exactly to the degree in which he himself stands by the country. It is patriotic to support him insofar as he efficiently serves the country. It is unpatriotic not to oppose him to the exact extent that by inefficiency or otherwise he fails in his duty to stand by the country. In either event, it is unpatriotic not to tell the truth, whether about the president or anyone else.
