Impulse by Dr David Lewisを読んでいます。
Perhaps my wife won't like London; then the sentence is banishment and degradation into indolent idle fool. Having completed this very methodical, System R, 'cost-benefit' analysis he was left in no doubt as to his next move. Beneath the first column he wrote in a firm hand: 'Marry - Marry - Marry Q.E.D.' The following year he proposed to his cousin Emma Wedgwood.
"Q.E.D." とは何の意味でしょう？
・Cambridge English Dictionary: abbreviation for the Latin phrase "quod erat demonstrandum": written or said after an argument to show that you have proved something that you wanted to prove
・Wikipedia: Q.E.D. (also written QED) is an initialism of the Latin phrase quod erat demonstrandum, meaning "what was to be demonstrated", or, less formally, "thus it has been demonstrated". The phrase is traditionally placed in its abbreviated form at the end of a mathematical proof or philosophical argument when the original proposition has been exactly restated as the conclusion of the demonstration. The abbreviation thus signals the completion of the proof.
証明の最後の加える略語の様で、ダーウィンなら使いそうですが、上記の引用文で 'Marry' の後に付ける意味が今一つピンときません。更に他の辞書を見ましたが、次の辞書の説明が納得できるものでした。
・Macmillan Dictionary:
a) used for saying that a particular fact proves that what you have said is true
b) Ways of emphasizing that something is true or exact: actually, certainly, clearly...
本気だという事を強調するために使ったと解するのが正解の様です。 Q.E.D.。
