Four Types Of Change
- Change (motion) is a real feature of the world and can be classified into local, qualitative, quantitative, and substantial change.
- Aristotle and Aquinas treat 'motion' broadly as actualization of potential, not as emerging from nothing.
How A Class Sparked A Philosopher
- Ed Feser recounts how a Greek literature pre-Socratic unit hooked him on philosophy as an undergraduate.
- That class shaped his life and led him into deep engagement with Parmenides and Aristotle.
Parmenides Versus Actuality/Potentiality
- Parmenides argued change is impossible because it would require something to come from non-being to being.
- Aristotle replies change is potential becoming actual, so potentiality is real and not mere nothingness.
