Abstract

The paradox of increase in an ancient argument purporting to show that nothing can grow by acquiring new parts. If it is sound, similar reasoning leads to the more general conclusion that nothing can ever change its parts. After discussing the implicationsof this principle, the paper lays out the paradox in a way that reveals the premises that figure in it. It emerges that the paradox has no easy solution, and can be resisted only by taking on one of five serious metaphysical commitments.
