Observations On The Increase Of Infidelity: To Which Are Added, Animadversions On The Writings Of Several Modern Unbelievers, And Especially The Ruins Of Mr. Volney (1797) is a book written by Joseph Priestley. The book is a response to the growing trend of infidelity in the late 18th century, and it aims to provide a defense of Christianity against the attacks of modern unbelievers. In the book, Priestley discusses the various reasons why people are turning away from Christianity, including the influence of science, the spread of rationalism, and the perceived inconsistencies in the Bible. He argues that these objections are based on misunderstandings and that Christianity is still a valid and relevant belief system. The second part of the book is a critique of the writings of several modern unbelievers, including the French philosopher Voltaire and the German philosopher Immanuel Kant. Priestley offers a detailed analysis of their arguments and points out the flaws in their reasoning. The final section of the book focuses on a specific work by Volney called The Ruins, which Priestley argues is a flawed and misleading account of ancient civilizations. He provides a detailed critique of the book and argues that it is not a reliable source of information. Overall, Observations On The Increase Of Infidelity is a passionate defense of Christianity and a response to the growing trend of skepticism in the late 18th century. It provides a detailed analysis of the objections raised by modern unbelievers and offers a compelling defense of the Christian faith.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
