Letters Concerning Mind: To Which Is Added, A Sketch Of Universal Arithmetic (1750)

""Letters Concerning Mind: To Which Is Added, A Sketch Of Universal Arithmetic"" is a book written by John Petvin in 1750. The book is divided into two parts. The first part contains a series of letters discussing the nature of the mind and its relation to the body, as well as the concept of free will. The second part of the book is a brief introduction to Universal Arithmetic, which is a system of arithmetic that uses symbols to represent numbers and operations. Petvin argues that Universal Arithmetic is a more efficient and accurate way of doing arithmetic than traditional methods. The book is considered an important work in the history of philosophy and mathematics, and is still studied today.Comprehending The Differential Calculus, And The Doctrine Of Fluxions.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
