<p>The term <em>dilemma</em> is attributed by <a title="Gabriel Nuchelmans" href="https://en.m.wikipedia.org/wiki/Gabriel_Nuchelmans">Gabriel Nuchelmans</a> to <a title="Lorenzo Valla" href="https://en.m.wikipedia.org/wiki/Lorenzo_Valla">Lorenzo Valla</a> in the 15th century, in later versions of his logic text traditionally called <em>Dialectica.</em> Valla claimed that it was the appropriate Latin equivalent of the Greek <em>dilemmaton.</em> Nuchelmans argued that his probable source was a logic text of c.1433 of <a title="George of Trebizond" href="https://en.m.wikipedia.org/wiki/George_of_Trebizond">George of Trebizond</a>.<sup id="cite_ref-2" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-2">[2]</a></sup> He also concluded that Valla had reintroduced to the Latin West a type of argument that had fallen into disuse.<sup id="cite_ref-3" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-3">[3]</a></sup></p>
<p>Valla's neologism did not immediately take hold, preference being given to the established Latin term <em>complexio</em>, used by <a title="Cicero" href="https://en.m.wikipedia.org/wiki/Cicero">Cicero</a>, with <em>conversio</em> applied to the upsetting of dilemmatic reasoning. With the support of <a title="Juan Luis Vives" href="https://en.m.wikipedia.org/wiki/Juan_Luis_Vives">Juan Luis Vives</a>, however, <em>dilemma</em> was widely applied by the end of the 16th century.<sup id="cite_ref-4" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-4">[4]</a></sup></p>
<p>In the form "you must accept either A, or B" — here A and B are propositions each leading to some further conclusion — and applied incorrectly, the dilemma constitutes a <a class="mw-redirect" title="False dichotomy" href="https://en.m.wikipedia.org/wiki/False_dichotomy">false dichotomy</a>, that is, a <a title="Fallacy" href="https://en.m.wikipedia.org/wiki/Fallacy">fallacy</a>. Traditional usage distinguished the dilemma as a "horned syllogism" from the <a class="mw-redirect" title="Sophism" href="https://en.m.wikipedia.org/wiki/Sophism">sophism</a> that attracted the Latin name <em>cornutus.</em><sup id="cite_ref-5" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-5">[5]</a></sup> The original use of the word <em>horns</em> in English has been attributed to <a title="Nicholas Udall" href="https://en.m.wikipedia.org/wiki/Nicholas_Udall">Nicholas Udall</a> in his 1548 book <em>Paraphrases</em>, translating from the Latin term <em>cornuta interrogatio.</em><sup id="cite_ref-6" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-6">[6]</a></sup></p>

<p>In <a class="mw-redirect" title="Propositional logic" href="https://en.m.wikipedia.org/wiki/Propositional_logic">propositional logic</a>, <em>dilemma</em> is applied to a group of <a class="mw-redirect" title="Rules of inference" href="https://en.m.wikipedia.org/wiki/Rules_of_inference">rules of inference</a>, which are in themselves valid rather than fallacious. They each have three premises, and include the <a title="Constructive dilemma" href="https://en.m.wikipedia.org/wiki/Constructive_dilemma">constructive dilemma</a> and <a title="Destructive dilemma" href="https://en.m.wikipedia.org/wiki/Destructive_dilemma">destructive dilemma</a>.<sup id="cite_ref-9" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-9">[9]</a></sup> Such arguments can be refuted by showing that the disjunctive premise — the "horns of the dilemma" — does not in fact hold, because it presents a false dichotomy. You are asked to accept "A or B", but counter by showing that is not all. Successfully undermining that premise is called "escaping through the horns of the dilemma".<sup id="cite_ref-10" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-10">[10]</a></sup></p>

<p>In law, Valentin Jeutner has argued that the term "legal dilemma" could be used as a <a class="extiw" title="wiktionary:term of art" href="https://en.wiktionary.org/wiki/term_of_art">term-of-art</a>, to describe a situation where a legal subject is confronted with two or more legal norms that the legal subject cannot simultaneously comply with.<sup id="cite_ref-17" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-17">[17]</a></sup></p>
<p>Examples include contradictory contracts where one clause directly negates another clause, or conflicts between fundamental (e.g. <a title="Constitutional law" href="https://en.m.wikipedia.org/wiki/Constitutional_law">constitutional</a>) legal norms. <a title="Gottfried Wilhelm Leibniz" href="https://en.m.wikipedia.org/wiki/Gottfried_Wilhelm_Leibniz">Leibniz'</a>s 1666 doctoral dissertation <em>De casibus perplexis</em> (Perplexing Cases) is an early study of contradictory legal conditions.<sup id="cite_ref-18" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-18">[18]</a></sup> In domestic law, it has been argued that the <a title="Federal Constitutional Court" href="https://en.m.wikipedia.org/wiki/Federal_Constitutional_Court">German Constitutional Court</a> confronted a legal dilemma when determining, in connection with proceedings relating to the German <a title="Luftsicherheitsgesetz" href="https://en.m.wikipedia.org/wiki/Luftsicherheitsgesetz">Aviation Security Act</a>, whether a government official could intentionally kill innocent civilians by shooting down a hijacked airplane that would otherwise have crashed into a football stadium, killing tens of thousands.<sup id="cite_ref-19" class="reference"><a href="https://en.m.wikipedia.org/wiki/Dilemma#cite_note-19">[19]</a></sup></p>
