Episode notes
Books As An Information Technology
- Books function as an information technology combining 'software' (ideas) and 'hardware' (the book object).
- The book's physical thingness enables persistent, sharable scaffolding for ideas across readers and time.
Augustine's Garden Moment
- Joel tells Augustine's Confessions where Augustine opens Paul's letters at random and finds comfort.
- Augustine's act of marking the place highlights the book's 'thingness' as crucial to that experience.
