I would suggest reading John Earman's _World Enough and Space-Time: Absolute versys Relational Theories of Space and Time and Lawrence Sklar's _Space , Time, and Spacetime_. Both books discuss Newton's rotating bucket thought experiment and a few others of his. Also, the former actually has the full text of Newton's Scholium. I also recommend it because the second chapter is devoted to no less than half a dozen different views of classical spacetime, from Mach's to Aristotle's.
