The concept of the duality of human nature is a central theme in Robert Louis Stevenson's novel 'Strange Case of Dr Jekyll and Mr Hyde', which is explored in the 'The Great Political Fictions: Dr Jekyll and Mr Hyde' episode of the 'Past Present Future' podcast.

In this episode, host David Runciman delves into how the novel confounds our expectations about good and evil, and how it relates to contemporary political issues like Q-Anon and Hillary Clinton.

The duality of human nature is also a core theme in the 'Copy of The Two You's | Joel Osteen' episode of the 'Joel Osteen Podcast', which focuses on the two opposing 'yous' or natures within every person and the importance of walking in faith and discipline.
