Setting out from two problems of dynamics both of which require for their solution the method of infinitesimals, CSP attempts an explanation of the method of infinitesimals, which requires, in turn, an explanation of collections and multiplicity. In addition, there is a discussion of the different modes of being, followed by a discussion of the distinction between reality and existence (for the purpose of showing that although nothing unreal can exist, something may be non-existent without being unreal).
