を以前書きましたが、フランスの18世紀の貴族たちの世界は「ポリアモリー」が普通だったのか？
と思えてしまいます。
（まあ、フランスだけでなく、18世紀にかぎらず、でしょうが。）
ところで、ヴォルテールについては、ちょっと悲しい過去があるかもしれないという研究家がいるようです。
Unhappy Voltaire, or `I Shall Never Get Over it as Long as I Live' (researchgate.net)
Voltaire was the victim of sexual abuse in childhood, though his biographers have been dismayingly reluctant to recognize this. It is suggested here that the experience affected his adult sexuality, and new evidence is introduced to support the view that he was bisexual. The claim of Besterman and others that Voltaire was hostile to homosexuality (a topic which is central to Candide) is rejected. The Philosophical Letters show that Voltaire was reluctant to think in terms of an interior self (thereby placing himself in opposition not only to Pascal but to Locke), perhaps because of the trauma he had suffered. Candide represents Voltaire's attempt to come to terms with his experience of evil and misery, and functioned as a form of self-therapy. Far from representing a new pessimism on Voltaire's part, it marks the point at which he began to experience happiness, redirecting his energies to helping other innocent victims, and experiencing good health for the first time in his life.
