图书简介
Laws of Form is a seminal work in foundations of logic, mathematics and philosophy published by G Spencer-Brown in 1969. The book provides a new point of view on form and the role of distinction, markedness and the absence of distinction (the unmarked state) in the construction of any universe. A conference was held August 8–10, 2019 at the Old Library, Liverpool University, 19 Abercromby Square, L697ZN, UK to celebrate the 50th anniversary of the publication of Laws of Form and to remember George Spencer-Brown, its author. The book is a collection of paperers introducing and extending Laws of Form written primarily by people who attended the conference in 2019.Key FeaturesThis is a unique book consisting of new and groundbreaking research and viewpoints related to Laws of FormThis book can serve as companion and as an introduction to Spencer-Brown’s book Laws of FormThe reader will find significant new mathematics that has grown from Laws of Form and significant philosophical articulations that grow from this groundBertrand Russell said of Laws of Form that "In this book Mr Spencer-Brown has succeeded in doing what is very rare indeed. He has revealed a new calculus of great power and simplicity. I congratulate him." Indeed the present book is a celebration and an enthusiastic confirmation of this assessment of Russell
