Episode notes
Read Popper With Historical Caution
- When reading Popper, expect contradictions between early and late writings and seek later clarifications.
- Treat Popper's early bold claims cautiously and consult later texts for nuanced positions.
Einstein's Dogged Belief Example
- Bruce uses Einstein's decade-long pursuit of a theory as an example of productive 'dogmatism' sustaining difficult work.
- He notes the same dogmatism later drove Einstein to a wrong pursuit, showing double-edged nature of belief.
Corroboration Divides Popperians
- Many critical rationalists reject Popper's 'degrees of corroboration' as unnecessary, creating a rift within the Popperian community.
- This dispute partly explains why Strevens' portrayal of Popper resonates with some critics.
