Reformed Logic: A System Based on Berkeley's Philosophy with an Entirely New Method of Dialectic

"Reformed Logic" by D. B. McLachlan is a philosophical treatise written in the late 19th century. The book aims to present a coherent system of logic grounded in Berkeley's philosophy while proposing a novel dialectical method. McLachlan’s work critiques current metaphysical doctrines, arguing that they often emerge from misconceptions, and intends to make the principles of reasoning accessible for educational purposes. The opening portion of the work serves as a preface and introduces the central theme that a lack of clarity in logic texts has led to confusion in the field of philosophy. McLachlan asserts that existing philosophical systems are clouded by incorrect premises, making them difficult to understand. He emphasizes the importance of properly recognizing the relationship between mind and substance, and undertakes to clarify the principles of logic through a substantialist lens, while also laying the groundwork for the later sections that will delve into reasoning, perception, memory, and dialectical processes.
