Absurdities of Immaterialism by Orson Pratt is a philosophical work that critiques the concept of immaterialism, the belief that matter does not exist and that only mind or spirit is real. In this book, Pratt argues against this idealist philosophy, asserting that material substances are essential to understanding the universe and human experience. He presents a logical and theological examination of the nature of existence, countering immaterialist claims with evidence drawn from science, scripture, and reason.Pratt's work is an effort to defend the reality of the material world, emphasizing the tangible and observable aspects of life as foundational to truth. Through his critique, he challenges prevailing philosophical trends of the time, advocating for a materialistic worldview that aligns with the doctrines of the Latter-day Saints. The book is both a philosophical treatise and a theological defense of the physical world as a meaningful and divinely created entity.
