Duplicity

Duplicity (pronounced doo-plis-i-tee or dyoo-plis-i-tee)

(1) Deceitfulness in speech or conduct, as by speaking or acting in two different ways to different people concerning the same matter; double-dealing.

(2) An act or instance of such deceitfulness.

(3) In law, the act or fact of including two or more offenses in one count, or charge, as part of an indictment, thus violating the requirement that each count contain only a single offense.

1400–1450: From the Late Middle English, from the Old French duplicite, from the Late Latin duplicitatem (nominative duplicitas (doubleness)).  Technically, the word wa borrowed from Latin duplicāre (double), present active infinitive of duplicō and the Medieval Latin duplicitās differed with ite replacing itās.  The notion is of being "double" in one's conduct ultimately is derived from the Ancient Greek diploos (treacherous, double-minded) which translates literally as "twofold, double".  Related in Medieval Latin was ambiguity, noun of quality from duplex, genitive (duplicis (two-fold)).

Duplicity good and bad

Because such conduct is inherent to human interaction, there are many words either similar in meaning or a synonym of duplicity.  Duplicity is the form of deceitfulness that leads one to give two impressions, either or both of which may be false.  Deceit is the quality that prompts intentional concealment or perversion of truth for the purpose of misleading.  The quality of guile leads to craftiness in the use of deceit; one uses guile and trickery to attain one's ends. Hypocrisy is the pretence of possessing virtuous qualities such as sincerity, goodness or devotion.  Fraud refers usually to the practice of subtle deceit or duplicity by which one may derive benefit at another's expense.  Trickery is the quality that leads to the use of tricks and habitual deception.  In modern English usage, the most common sense of duplicity is “deceitfulness.”  The roots of this meaning are in the initial dupl from the Latin duplex (twofold, or double).  We do seem a duplicitous lot.

Alexander Haig (1924–2010; US Secretary of State 1981-1982) & Ronald Reagan (1911–2004; US President 1981-1989) (left) and Lord Carrington (1919–2018; UK Foreign Secretary 1979-1982) & Margaret Thatcher (1925–2013; UK Prime Minister 1979-1990) (right).

To accuse someone duplicity is usually to allege or suggest something negative, the idea that someone has acted in a manner perhaps not dishonest but certainly misleading or dishonorable.  However there are fields of endeavor where the successfully duplicitous are often admired and the most Machiavellian can be held in awe.  In international relations, it’s true in the upper reaches of diplomacy.

Duplicity, art and science: Haig and Carrington, the White House, 26 February 1981.

More than General Colin Powell (b 1937; US Secretary of State 2001-2005) and more even than General Dwight Eisenhower (1890–1969; US President 1953-1961), General Alexander Haig (1924-2010) was an exemplar of that uniquely Washington DC creature, the political soldier, whose career shuttled between the military, diplomacy and politics.  After a meeting in 1981, Haig was heard to remark the UK Foreign Secretary, Lord Carrington, was a "duplicitous bastard".  Beyond the beltway, that would be a disparaging comment, but, in the world of international diplomacy, it’s more an expression of admiration of professional skill.
