Modus vivendi

Last updated

Modus vivendi is a Latin phrase that means "mode of living" or “way of life”. It often is used to mean an arrangement or agreement that allows conflicting parties to coexist in peace. In science it is used to describe lifestyles. [1]

Latin Indo-European language of the Italic family

Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets and ultimately from the Phoenician alphabet.


Modus means "mode", "way", "method", or "manner". Vivendi means "of living". The phrase is often used to describe informal and temporary arrangements in political affairs. For example, if two sides reach a modus vivendi regarding disputed territories, despite political, historical or cultural incompatibilities, an accommodation of their respective differences is established for the sake of contingency.

In diplomacy, a modus vivendi is an instrument for establishing an international accord of a temporary or provisional nature, intended to be replaced by a more substantial and thorough agreement, such as a treaty. [2] Armistices and instruments of surrender are intended to achieve a modus vivendi.

Treaty Express agreement under international law entered into by actors in international law

A treaty is a formal written agreement entered into by actors in international law, namely sovereign states and international organizations. A treaty may also be known as an international agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms. Regardless of terminology, all these instruments may be considered treaties subject to the same rules under international law.

Armistice situation in a war where the warring parties agree to stop fighting

An armistice is a formal agreement of warring parties to stop fighting. It is not necessarily the end of a war, since it may constitute only a cessation of hostilities while an attempt is made to negotiate a lasting peace. It is derived from the Latin arma, meaning "arms" and -stitium, meaning "a stopping".

Surrender (military) cessation of fighting by the losing party

Surrender, in military terms, is the relinquishment of control over territory, combatants, fortifications, ships or armament to another power. A surrender may be accomplished peacefully, without fighting, or it may be the result of defeat in battle. A sovereign state may surrender following defeat in a war, usually by signing a peace treaty or capitulation agreement. A battlefield surrender, either by individuals or when ordered by officers, normally results in those surrendering becoming prisoners of war.


In Season 1, Episode 25, of Star Trek: The Original Series , entitled "The Devil in the Dark", Captain James T. Kirk used the term to describe a possible relationship between miners on a Federation planet and a rock tunneling indigenous species called 'The Horta'. He said, "Seems to me we could make an agreement, reach a modus vivendi. They tunnel, you collect and process, and your processing operation would be a thousand times more profitable." [3]

Star Trek is an American science-fiction television series created by Gene Roddenberry that follows the adventures of the starship USS Enterprise (NCC-1701) and its crew. It later acquired the retronym of Star Trek: The Original Series (TOS) to distinguish the show within the media franchise that it began.

"The Devil in the Dark" is the twenty-fifth episode of the first season of the American science fiction television series Star Trek. The show is about a 23rd century starship that explores space, and the show's futuristic vision and moral ethos became famous in late 20th century pop-culture.

James T. Kirk Character in the Star Trek media franchise

James Tiberius "Jim" Kirk is a fictional character in the Star Trek franchise. Kirk first appears in Star Trek: The Original Series and has been portrayed in numerous films, books, comics, webisodes, and video games. As the captain of the starship USS Enterprise, Kirk leads his crew as they explore new worlds, new civilizations, and "boldly go where no man has gone before". Often, the characters of Spock and Leonard McCoy act as his logical and emotional sounding boards, respectively.

The term often refers to Anglo-French relations from the 1815 end of the Napoleonic Wars to the 1904 Entente Cordiale.[ citation needed ]

Napoleonic Wars Series of early 19th century European wars

The Napoleonic Wars (1803–1815) were a series of major conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European powers formed into various coalitions, financed and usually led by the United Kingdom. The wars stemmed from the unresolved disputes associated with the French Revolution and its resultant conflict. The wars are often categorised into five conflicts, each termed after the coalition that fought Napoleon: the Third Coalition (1805), the Fourth (1806–07), the Fifth (1809), the Sixth (1813), and the Seventh (1815).

Entente Cordiale series of agreements between the United Kingdom and France about colonies in Africa, Siam (Thailand), Newfoundland, and New Hebrides (Vanuatu)

The Entente Cordiale was a series of agreements signed on 8 April 1904 between the United Kingdom and the French Republic which saw a significant improvement in Anglo-French relations. Beyond the immediate concerns of colonial expansion addressed by the agreement, the signing of the Entente Cordiale marked the end of almost a thousand years of intermittent conflict between the two states and their predecessors, and replaced the modus vivendi that had existed since the end of the Napoleonic Wars in 1815 with a more formal agreement. The Entente Cordiale was the culmination of the policy of Théophile Delcassé, France's foreign minister from 1898, who believed that a Franco-British understanding would give France some security against any German system of alliances in Western Europe. Credit for the success of the negotiation belongs chiefly to Paul Cambon, France's ambassador in London, and to the British foreign secretary Lord Lansdowne.

In propositional logic, modus ponens is a rule of inference. It can be summarized as "P implies Q and P is asserted to be true, therefore Q must be true."

In propositional logic, modus tollens is a valid argument form and a rule of inference. It is an application of the general truth that if a statement is true, then so is its contrapositive.

Propositional calculus is a branch of logic. It is also called propositional logic, statement logic, sentential calculus, sentential logic, or sometimes zeroth-order logic. It deals with propositions and argument flow. Compound propositions are formed by connecting propositions by logical connectives.

<i>Principia Mathematica</i> Three-volume work on the foundations of mathematics

The Principia Mathematica is a three-volume work on the foundations of mathematics written by Alfred North Whitehead and Bertrand Russell and published in 1910, 1912, and 1913. In 1925–27, it appeared in a second edition with an important Introduction to the Second Edition, an Appendix A that replaced ✸9 and all-new Appendix B and Appendix C. PM is not to be confused with Russell's 1903 The Principles of Mathematics. PM was originally conceived as a sequel volume to Russell's 1903 Principles, but as PM states, this became an unworkable suggestion for practical and philosophical reasons: "The present work was originally intended by us to be comprised in a second volume of Principles of Mathematics... But as we advanced, it became increasingly evident that the subject is a very much larger one than we had supposed; moreover on many fundamental questions which had been left obscure and doubtful in the former work, we have now arrived at what we believe to be satisfactory solutions."

"What the Tortoise Said to Achilles", written by Lewis Carroll in 1895 for the philosophical journal Mind, is a brief allegorical dialogue on the foundations of logic. The title alludes to one of Zeno's paradoxes of motion, in which Achilles could never overtake the tortoise in a race. In Carroll's dialogue, the tortoise challenges Achilles to use the force of logic to make him accept the conclusion of a simple deductive argument. Ultimately, Achilles fails, because the clever tortoise leads him into an infinite regression.

Ad hoc is a Latin phrase meaning literally "for this". In English, it generally signifies a solution designed for a specific problem or task, non-generalizable, and not intended to be able to be adapted to other purposes.

A glittering generality is an emotionally appealing phrase so closely associated with highly valued concepts and beliefs that it carries conviction without supporting information or reason. Such highly valued concepts attract general approval and acclaim. Their appeal is to emotions such as love of country and home, and desire for peace, freedom, glory, and honor. They ask for approval without examination of the reason. They are typically used by politicians and propagandists.

"Agree to disagree" or "agreeing to disagree" is a phrase in English referring to the resolution of a conflict whereby all parties tolerate but do not accept the opposing position(s). It generally occurs when all sides recognise that further conflict would be unnecessary, ineffective or otherwise undesirable. They may also remain on amicable terms while continuing to disagree about the unresolved issues.

Backward chaining is an inference method described colloquially as working backward from the goal. It is used in automated theorem provers, inference engines, proof assistants, and other artificial intelligence applications.

In propositional logic, transposition is a valid rule of replacement that permits one to switch the antecedent with the consequent of a conditional statement in a logical proof if they are also both negated. It is the inference from the truth of "A implies B" the truth of "Not-B implies not-A", and conversely. It is very closely related to the rule of inference modus tollens. It is the rule that:

Logical form form for logical arguments, obtained by abstracting from the subject matter of its content terms

In philosophy and mathematics, a logical form of a syntactic expression is a precisely-specified semantic version of that expression in a formal system. Informally, the logical form attempts to formalize a possibly ambiguous statement into a statement with a precise, unambiguous logical interpretation with respect to a formal system. In an ideal formal language, the meaning of a logical form can be determined unambiguously from syntax alone. Logical forms are semantic, not syntactic constructs; therefore, there may be more than one string that represents the same logical form in a given language.

In philosophy, a formal fallacy, deductive fallacy, logical fallacy or non sequitur is a pattern of reasoning rendered invalid by a flaw in its logical structure that can neatly be expressed in a standard logic system, for example propositional logic. It is defined as a deductive argument that is invalid. The argument itself could have true premises, but still have a false conclusion. Thus, a formal fallacy is a fallacy where deduction goes wrong, and is no longer a logical process. This may not affect the truth of the conclusion, since validity and truth are separate in formal logic.

Owing to its origin in ancient Greece and Rome, English rhetorical theory frequently employs Greek and Latin words as terms of art.

In information technology a reasoning system is a software system that generates conclusions from available knowledge using logical techniques such as deduction and induction. Reasoning systems play an important role in the implementation of artificial intelligence and knowledge-based systems.

Logic Study of inference and truth

Logic is the systematic study of the form of valid inference, and the most general laws of truth. A valid inference is one where there is a specific relation of logical support between the assumptions of the inference and its conclusion. In ordinary discourse, inferences may be signified by words such as therefore, thus, hence, ergo, and so on.
