Ancient Greek ideas about matter

  • What did Aristotle think?
  • Democritus’ ideas about matter were similar to Dalton’s ideas (which were correct), but people believed Aristotle’s incorrect ideas for about 2,000 years.  Why?  What was Dalton able to do that the ancient Greeks were not able to do?
