Extract

The two statements “Two different objects cannot occupy the same place at the same time” and “An object cannot be in two different places at the same time” are axioms of our everyday understanding of objects, space and time. We develop a first-order theory OST (Objects, Space and Time) in which formal equivalents of these two statements are taken as axioms. Using the theory OST, we uncover other fundamental principles of objects, space and time. We attempt to understand the logical nature of these principles, to investigate their formal consequences, and to identify logical alternatives to them. For easy reference, all of the nonlogical axioms of OST are listed together at the end of §2. In §3, we introduce two possible extensions of OST.
