What philosophical ideas from Boethius appear in Geoffrey Chaucer’s writing?

The philosophical ideas of the Roman philosopher Boethius, particularly those found in his influential work the Consolation of Philosophy, had a profound and lasting impact on Geoffrey Chaucer’s thought and literary art.1

Chaucer’s engagement with Boethius included a careful prose translation of the Consolation, which explores fundamental questions regarding free will, God’s foreknowledge, destiny, fortune, and the nature of true versus false happiness. These concepts were essential to how a right-minded individual should direct their thoughts and actions to achieve eternal salvation.1

The influence of these Boethian ideas is pervasive in Chaucer’s poem Troilus and Criseyde, where they are interspersed throughout the narrative to address themes of determinism and human agency. Ultimately, the poem uses these philosophical frameworks to contrast the folly of complete immersion in earthly, sexual love with the eternal love of God, a perspective highlighted as Troilus’s soul ascends into the heavens at the work's conclusion.12
