Clavis Universalis Or A New Inquiry After Truth

Clavis Universalis is a philosophical treatise written by Samuel Parr, in which he presents an argument for the non-existence or impossibility of an external world. The book is divided into several chapters, each of which explores a different aspect of the argument. Parr begins by defining the concept of an external world and explaining why it is commonly accepted as real. He then introduces his argument, which is based on the idea that all knowledge is ultimately subjective and that there is no way to prove the existence of an external world beyond our own perceptions. Throughout the book, Parr draws on a wide range of philosophical and scientific sources to support his argument. He discusses the work of philosophers such as Descartes and Berkeley, as well as scientific theories such as the nature of light and the structure of the eye. Despite the challenging nature of the argument, Parr writes in a clear and accessible style, making the book suitable for both scholars and general readers interested in philosophy. Clavis Universalis remains an important work in the history of philosophy and continues to provoke debate and discussion among scholars today.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
