In the famous Correspondence with Clarke, which took place during the last year of Leibniz s life, Leibniz advanced several arguments purporting to refute the absolute theory of space and time that was held by Newton and his followers. The main aim of this book is to reassess Leibniz s attack on the Newtonian theory in so far as he relied on the principle of the identity of indiscernibles. The theological side of the controversy is not ignored but isolated and discussed in the last three chapters, which deal with problems connected with the notions of omnipotence and omniscience."
