Laws of Form is a book by George Spencer-Brown published in 1969. It is about logic, mathematics, and philosophy. The mathematical systems that Spencer-Brown presented in the book are known by the names "calculus of indications", "distinction calculus", and often just "LOF".
Laws of Form grew out of the author's work in electronic engineering. The book has been published in several editions and translations and has never gone out of print. A short book, its mathematical part is only 55 pages long.
Spencer-Brown's philosophy was influenced by Ludwig Wittgenstein, R.D. Laing, Charles Sanders Peirce, Bertrand Russell, and Alfred North Whitehead.
