The Religion of Duty is a philosophical treatise written by Felix Adler, an American philosopher and social reformer, in 1905. The book is a collection of lectures that Adler delivered at the Ethical Culture Society in New York, where he was the founder and leader. The central theme of the book is the concept of duty, which Adler argues is the foundation of morality and the key to a fulfilling life.Adler begins by examining the traditional religious views of duty and morality, which he believes are outdated and inadequate for modern society. He then proposes a new ethical system, which he calls the Religion of Duty, that is based on reason, humanism, and social responsibility. According to Adler, the Religion of Duty is a non-theistic religion that emphasizes the importance of living a moral and ethical life based on our duty to ourselves, others, and society as a whole.Throughout the book, Adler explores various aspects of the Religion of Duty, including its principles, practices, and applications. He discusses the role of reason and conscience in moral decision-making, the importance of social justice and equality, and the need for ethical education and training. He also addresses practical issues such as crime, punishment, and war, and offers his views on how the Religion of Duty can help us address these challenges.Overall, The Religion of Duty is a thought-provoking and insightful work that challenges traditional religious and moral beliefs and offers a new vision for ethical living. It is a must-read for anyone interested in philosophy, ethics, or social reform.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
