"Ich rede Unsinn" – Der Logiker George Spencer-Brown

This book is a collection of poems by G. Spencer Brown, who is also known for his philosophical and mathematical works, particularly 'Laws of Form'. The poems in 'Only Two Can Play This Game' reflect his unique perspective and style, which have been influential in various intellectual circles.

Laws of Form is a work that delves into the fundamental concept of distinction and its role in creating logical systems. Published in 1969, it introduces the 'primary algebra' and 'calculus of indications', which are essentially minimalist notations for two-element Boolean algebra. The book explores how the act of making a distinction creates space and time, and it discusses the emergence of self-reference within the system. It has influenced various fields, including cybernetics, and has been noted for its unique approach to propositional calculus and the philosophy of distinction.
