Book excerpt: Deism is the religion that has captivated brilliant minds throughout human history, such as Benjamin Franklin and Albert Einstein. The book "Deism: From Philosophy to Religion" explores the quest for knowledge of God. Marcel Dubois, a master of deism, presents a vision of God as a transcendental entity who established the natural laws of the universe. The book addresses the problem of limited and anthropomorphic understanding of God found in many religions. The proposed solution is reason as a tool to explore the divine through a non-dogmatic perspective. The book discusses topics such as the relationship between God, science, and human existence from a deistic perspective and brilliantly narrates the journey of the soul. With his experience as a master of deism, Marcel Dubois offers an in-depth insight into the principles of this non-dogmatic religious philosophy. The book invites the reader on a journey of questioning and reflection in the pursuit of understanding God and the universe, a quest that can only be undertaken through the use of reason.
