Episode notes
Abstraction in SICP
- SICP defines abstraction as naming and manipulating compositions, enabling their use as units.
- This involves ignoring the composition's internal details and treating it as a single entity.
Locke's Abstraction
- John Locke's definition of abstraction involves understanding an idea by isolating it from its context.
- This aligns with SICP's definition, where abstraction removes a composition from its concrete origins.
Liskov's Abstraction
- Zach Tellman prefers Barbara Liskov's definition of abstraction: treating different things as the same.
- This emphasizes ignoring differences and focusing on shared characteristics, like interchangeable parts with the same interface.
