内容简介：
Featuring the Gestalt Model and the Perspectivist conception of science, this book is unique in its non-relativistic development of the idea that successive scientific theories are logically incommensurable. This edition includes four new appendices in which the central ideas of the book are applied to subatomic physics, the distinction between laws and theories, the relation between absolute and relative conceptions of space, and the environmental issue of sustainable development.
