Episode notes
Making Is Revealing Truth
- The four causes unify in a bringing-forth (poiesis) that lets things move from concealment to presence.
- Heidegger links this unconcealment to aletheia, treating truth as revealing.
Technology As A Mode Of Revealing
- Technology is not merely an instrument; it is a mode of revealing that organizes and sets reality.
- Sadler stresses techné and epistēmē as distinct but both revealing forms of truth.
Modern Technology Challenges Nature
- Modern technology "challenges forth" nature to unlock, transform, store, and distribute energy as calculable resources.
- This process orders things toward maximum yield and minimum expense, reshaping being.
