Can a single sentence change the way you see the world? My guest on this episode, James Geary thinks so.

Episode Summary
On this episode, I speak with writer and journalist James, whose lifelong fascination with aphorisms — the world’s shortest literary form — reveals why brevity really is the soul of wit.

James explains what makes an aphorism work, shares the five laws that define them, and explores how these concise little sayings have guided human thought from ancient times to social media.

We discuss:

• The difference between aphorisms and proverbs
• How short phrases can serve as decision-making tools and emotional signposts
• Why humour and contradiction are central to wisdom
• How modern culture, marketing, and even AI continue the aphoristic tradition
• James’s book The World in a Phrase and why he chose to update it 20 years after originally publishing it

I also ask him whether my friend James Victore's phrase 'what made you weird as a kid, makes you great today' is an aphorism (spoiler alert: it is!).
