on lying

Sam Harris in a short book or should it be a booklet titled lying, writes in conclusion

As it was in Anna Karenina, Madame Bovary, and Othello, so it is in life. Most forms of private vice and public evil are kindled and sustained by lies. Acts of adultery and other personal betrayals, financial fraud, government corruption—even murder and genocide—generally require an additional moral defect: a willingness to lie.
Lying is, almost by definition, a refusal to cooperate with others. It condenses a lack of trust and trustworthiness into a single act. It is both a failure of understanding and an unwillingness to be understood. To lie is to recoil from relationship.
By lying, we deny others a view of the world as it is. Our dishonesty not only influences the choices they make, it often determines the choices they can make—and in ways we cannot always predict. Every lie is a direct assault upon the autonomy of those we lie to.
And by lying to one person, we potentially spread falsehoods to many others—even to whole societies. We also force upon ourselves subsequent choices—to maintain the deception or not—that can complicate our lives. In this way, every lie haunts our future. There is no telling when or how it might collide with reality, requiring further maintenance. The truth never needs to be tended in this way. It can simply be reiterated.
The lies of the powerful lead us to distrust governments and corporations. The lies of the weak make us callous toward the suffering of others. The lies of conspiracy theorists raise doubts about the honesty of whistle-blowers, even when they are telling the truth. Lies are the social equivalent of toxic waste—everyone is potentially harmed by their spread.
How would your relationships change if you resolved never to lie again? What truths might suddenly come into view in your life? What kind of person would you become? And how might you change the people around you?
It is worth finding out.

Mark Twain writes in on the decay of art of lying, thus

No fact is more firmly established than that lying is a necessity of our circumstances–the deduction that it is then a Virtue goes without saying. No virtue can reach its highest usefulness without careful and diligent cultivation–therefore, it goes without saying that this one ought to be taught in the public schools–even in the newspapers. What chance has the ignorant uncultivated liar against the educated expert? What chance have I against Mr. Per–against a lawyer? Judicious lying is what the world needs. I sometimes think it were even better and safer not to lie at all than to lie injudiciously. An awkward, unscientific lie is often as ineffectual as the truth.

Nietzsche writes

[D]eception, flattering, lying and cheating, talking behind the back, posing, living in borrowed splendor, being masked, the disguise of convention, acting a role before others and before oneself—in short, the constant fluttering around the single flame of vanity is so much the rule and the law that almost nothing is more incomprehensible than how an honest and pure urge for truth could have arisen among men. They are deeply immersed in illusions and dream images; their eye only glides only over the surface of things … their feeling nowhere leads into truth, but contents itself with the reception of stimuli, playing, as it were, a game of blind man’s bluff.

And Nietzsche asks again,

What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding. Truths are illusions which we have forgotten are illusions — they are metaphors that have become worn out and have been drained of sensuous force, coins which have lost their embossing and are now considered as metal and no longer as coins.

And yours truly asks, are they talking about the same thing? and between Harris’ position and that of Twain, where do you think most people fall? Is the position by Harris really tenable?
