'Poets are the unacknowledged legislators of the world' - Shelley
Suppose that Shelley is right and poetic sensibility (and by extension) artistic sensibility really does create the underpinning of decisions by the legislature. If so, a country with a taste for good poetry and art will make good laws. It also follows that bad poets and bad artists lay the foundations for bad laws.
The Joy of Painting with Bob Ross is a salutary lesson in this process.
