In the history of Western philosophy, dialetheism – the view that some sentences are both true and false – has been unpopular. This paper recovers a previously overlooked episode in the history of dialetheism. Specifically, it reconstructs a section of Robert Greville's The Nature of Truth (1640) in order to show that he was a dialetheist. Greville's consideration of the view that evil is a privation led him to endorse the claim that sinful acts are contradictory; they are the subjects of both being and non-being. The paper also explores responses to Greville from John Wallis and Nathaniel Culverwell.

罗伯特·格雷维尔论罪孽、匮乏和双神论

在西方哲学史上，辩证论——即某些句子既真又假的观点——一直不受欢迎。本文恢复了二元神论历史上以前被忽视的一段插曲。具体来说，它重建了罗伯特·格雷维尔的《真理的本质》 （1640）的一部分，以表明他是一个辩证论者。格雷维尔对邪恶是一种匮乏这一观点的思考使他赞同罪恶行为是矛盾的这一主张。它们既是存在又是非存在的主体。本文还探讨了约翰·沃利斯和纳撒尼尔·卡尔弗韦尔对格雷维尔的回应。
