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.
