Reading Questions: Aristotle, Physics VII, 5

 

(Questions for reflection, which cannot necessarily be answered simply by reading the text but should be provoked by it, are marked with an asterisk.)

 

1. What does Aristotle mean when he says, "... for at any moment when a thing is causing motion, it also has caused motion..."?

 

*2. Is this compatible with the notion of an instantaneous cause of motion?

 

3. Try to find a mathematical equation that would represent the ratios of forces (movents) to motions Aristotle gives in the first paragraph.

 

4. What restrictions does Aristotle put on the use of his proportions in the second paragraph?

 

5. What argument of Zeno's does Aristotle criticize? Try to reconstruct it in a way that might have made Zeno's reasoning seem provocative or paradoxical and would make Aristotle's reply make sense. (Is there an ambiguity on "making a sound"?)
